ALTERNATIVE MALE REPRODUCTIVE BEHAVIORS IN
THE BELIZEAN BLACK HOWLER MONKEY (ALOUATTA
PIGRA)

Robert H. Horwich
Robin C. Brockett
Clara B. Jones

Introduction

Individuals differ in many aspects of reproductive behavior.
Two or more reproductive phenotypes may be expressed dur-
ing the lifetime of an individual and between individuals
within the same population (Austad, 1984). Variation in
mating patterns may be studied for an understanding of
differential costs and benefits to survival and reproductive
success of alternative reproductive behaviors (ARBs). In this
paper we describe ARBs in male black howler monkeys
(Alouatta pigra).

The study of ARBs in primates has a long history (Hrdy,
1974; Clarke, 1983; Horwich, 1983; Boggess, 1984; Smuts,
1985; Jones, 1995). ARBs entail all discrete tactics and strat-
egies employed to maximize reproductive benefits (Austad,
1984). Dixson's (1998) discussion of ARBs by male pri-
mates shows that they exhibit various responses to gain ac-
cess to group membership and receptive females. Among
these responses, infanticide is, perhaps, the most controver-
sial and widely discussed. ARBs will arise whenever indi-
viduals compete for mates, and sexual selection theory pre-
dicts that males will be most likely to compete for mates
since females, or, rather, their fertilizeable ova, are expected
to be limiting resources (Trivers, 1972). Smuts (1987) found
that the expression of ARBs in male primates is related to
age, demography and life-history, stochastic effects (e.g.,
"accidents of history"), and unique traits of individuals (e.g.,
temperament or intelligence). Smuts' conclusions support
the view that the diversity ofintraspecific reproductive be-
haviors results from adaptive responses to local conditions,
in particular, the operational sex ratio within populations
(the ratio of males to females fecund at a given time), which
provides a measure of the intensity of sexual selection among
competitors (Emlen and Oring, 1977; also see Leland etal.,
1984).

Animals, Study Site, and Method

We conducted adlibitum observations of marked A. pigra at
the Community Baboon Sanctuary (CBS), Belize. The CBS
is a managed reserve of >18 sq. mi. formed in 1985 by a
cooperative agreement among private landowners (Horwich,
1990). Located at 1733'N, 8835'W, the CBS is a mosaic
of small farms, pastures and tropical moist forest fragments,
including riparian habitat along the Belize River (see
Horwich and Lyon, 1990). The study area has mapped trails,
and >1500 trees are mapped and identified. Rhythms in
plant communities are seasonal, with new leaf production
occurring primarily at the beginning of the rainy season (late


May or June) (Horwich and Lyon, 1990). In northern Belize
there are two flowering peaks. The largest peak occurs during
the dry season (February through May) with a second, smaller
peak occurring about one month after the rainy season begins
(Horwich and Lyon, 1990). Fruiting activity is variable, within
and between tree species (Horwich and Lyon, 1990). At any
one time in northern Belize, there are at least some tree species
producing fruit. Seasonally, there are two fruiting peaks: near
the end of the dry season and a month or so after the start of
the rainy season. Howler monkeys are wholly herbivorous, and
phenological perturbations may have significant consequences
for their populations.

Black howlers, large atelids, are generally polygynous (single
breeding male) with a modal group size of one adult male to
several adult females and immatures (Ostro et aL, 1999;
Horwich, unpublished data), although multimale-multifemale
(polygynandrous) groups may be found. Studies of demogra-
phy, ecology, social organization and behavior are in their early
stages (e.g., Horwich, 1983; Silver et al., 1998; Ostro et al.,
1999). Groups have been censused since 1985, and systematic
observations, including marking of animals and collection of
morphometric data have been carried out since the early 1990's.

Results

Primary Patterns
Table 1 shows male displacements within black howler mon-
key groups at the CBS between 1992 and 1997. "Displace-
ment" is used to mean that when one or more males enter an
established unit, one or more males are expelled. Several pat-
terns are noteworthy. First, males may transfer alone or in as-
sociation with one or more males. When more than one male
act together, they are always successful at expelling resident
males from their groups, although male alliances or coalitions
are not a necessary condition for successful expulsion. BBLT,
for instance, expelled 0 in March, 1995. It is important to
note, however, that, while single males successfully expelled a
group male on two occasions, transferring males moving alone
generally joined an existing group without expelling resident
males. In 1992, for example, WRT successfully joined the Bap-
tist troop without aggression and without expelling any males
from the troop. WRT later left Baptist troop with BWB to
displace Scar from the adjacent Fig troop in 1993 (Table 1).

Table 1 also demonstrates that changes in male membership
within groups was not always accompanied by overt male-male
aggression. Overt aggression among males appears to be most
likely when resident males are expelled or when a transferring
male attempts to enter a multi-male group. Infant disappear-
ance also appears most likely in these conditions.

Of further interest, as reported in Brockett et al. (1999), we
have identified a "cascade effect" in male takeovers whereby
takeover by an extra-group male may precipitate a resident male
to leave his group and initiate a takeover of another group (e.g.,
BBLT's takeover of Roxie troop in March, 1995 and LRT's
takeover of Bamboo troop in November, 1995). The effect that
we describe may be a response to some threshold of group den-

sity, possibly responsive to interaction rates, and expresses
the potential for stochastic dynamics of population processes.

Transferring males were observed to attempt copulation or
to copulate with resident females more than 50% of the time.
These events were almost always associated with male-male
aggression and subsequent infant disappearance. There ap-
pears to be a suite of associated responses for which sex and
aggression, including infanticide, are correlated, although be-
cause aggression is not associated with every transfer event,
its costs must often outweigh its benefits.

Secondary Patterns
Several additional aspects of male reproductive behavior were
observed. First, males may disperse from groups of origin,
sometimes their natal groups, and "float" in unoccupied habi-
tat or remain peripheral to an intact group on its home range.
Peripheral males have been observed to interact with group
members, usually adult females in a sexual context. The role
of females in determining who leads their social unit requires
further study.

On one occasion, an expelled adult male and female were
observed to form a new group, showing that new groups may
form from a process of forced fissioning. In another instance,
displaced individuals (an adult male, an adult female, and an
immature) were observed wandering within the home ranges
of two established groups. This result suggests that popula-
tion density at the study site is high and that habitat is satu-
rated; thus, all social units may not have home ranges.

Our observations suggest that "sperm competition" (see
Birkhead and Moller, 1998) may be a significant evolution-
ary force in both single-male and multimale-multifemale
groups ofA. pigra. Transferring males, for example, were ob-
served to solicit group females, and vice versa, before the male
successfully obtained group membership or left a group's home
range (see Horwich, 1983). Horwich (1983) observed copu-
lations between a female of one group and an extra-group
male, and even occasional copulations could generate "sperm


competition". In multimale-multifemale groups, newly-
transferred males and resident males were observed to copu-
late with the same resident females during the same estrus
cycles, suggesting "facultative polyandry" in A. pigra as has
been reported for A. palliata (Jones and Cortis-Ortiz, 1998).

Discussion

Figure 1 is a diagram of the ARBs exhibited by A. pigra in
the present study, as well as those ARB's suspected but not
directly observed. Our observations are preliminary, particu-
larly since we have limited data on age, kinship, and domi-
nance rank. However, it is clear that males exhibit creative
and highly variable reproductive tactics, highlighting the plas-
ticity of social organization in Alouatta as discussed by other
authors (e.g., Crockett and Eisenberg, 1987). The diversity
of mating tactics that we describe for A. pigra are similar to
those observed in other polygynous or polygynandrous so-
cieties (see Dixson, 1998) except that we have not observed
all male groups of>2 individuals (e.g., patas, Hanuman lan-
gurs), we have not observed a male capture and guard one
or more juvenile females until sexual maturity is attained
(e.g., Hamadryas baboon), we have not positively docu-
mented the acquisition of one or more females by a male
from an established group to form a new group (e.g., go-
rilla), nor have we positively documented the inheritance of
a group by a natal male (e.g., gelada and Hamadryas ba-
boons). Interspecific differences in ARBs are likely to be a
function of phylogeny and ecology as well as the factors noted
by Smuts (1987, see Introduction).

Future research must clarify the role that male alliances and
coalitions play in successful group takeovers as well as suc-
cessful resistance of takeovers. While our results suggest that
males belonging to multimale-multifemale groups success-
fully prevent extra-group males from expelling group males,
multimale-multifemale groups may not prevent the entry of
a persistent intruder (see Moore, 1999). Related to these
events is the role of male-female relations in determining
successful takeover and male tenure.

munity Baboon Sanctuary, Belize (based on Dixson, 1998).


A noteworthy result of our studies is the identification of a
"cascade effect", possibly a chaotic effect of habitat satura-
tion triggered by male takeovers. Cascade effects may have
important implications for conservation efforts if their de-
mographic consequences increase likelihood of population
extinctions by increasing stochastic factors. Cascade effects
illustrate the importance of identifying and measuring the
differential costs and benefits of polygynous and
polygynandrous mating systems to males in a range of envi-
ronmental conditions. Relying on economic models, Moore
(1999) has recently suggested that these ARBs are best un-
derstood in terms of "intruder pressure, mediated by popu-
lation density".

Future studies, including genetic analyses, will permit us to
compare the behavior and social organization ofA. pigra with
other species of Alouatta. In red howlers (A. seniculus), for
example, Crockett and Sekulic (1984) suggested that a male's
reproductive success subsequent to his taking over a group
was related to his ability to form coalitions with other males.
Our results support their conclusions and are consistent with
mechanisms of change in male tenure reported for A. palliata
(e.g., Jones, 1980; Clarke, 1983; Glander, 1992). While our
present results are preliminary and do not permit us to iden-
tify the complete range of similarities and differences in ARBs
between A. pigra and other species ofAlouatta, future stud-
ies by our and other research programs will enable us to under-

Introducao

0 mico-leao-dourado (Leontopithecus rosalia) 6 uma especie
native da mata Atlintica, sendo um dos primatas mais
ameacados de extincao (Kleiman et al., 1988; Dietz et al.,
1994). As causes principals dessa situaqco sio falta de habitat
e o trifico illegal de animals silvestres (Dietz et al., 1994;


Kierulff, 1994). As populag6es remanescentes
(aproximadamente 800 individuos) se encontram em
fragments de mata, sendo que 60% se encontram em Areas
protegidas, 25% em dreas nao protegidas mas seguras e 15%
em pequenos fragments florestais isolados e desprotegidos
(AMLD, 1998). Esta situacqo as faz vulneriveis a catAstrofes,
processes aleat6rios e efeitos antr6picos, como a caqa e
introducao de espcies ex6ticas (Meffe e Carroll 1994; Foose
et al., 1995).

O program de reintroduqIo do mico-leao-dourado ao seu
ambiente nativo, tem como alvo os animals de cativeiro
encontrados em zool6gicos (nos EUA e Europa), que sdo
trazidos a fragments de mata Atlantica de fazendas
particulares no estado do Rio de Janeiro (15 fazendas). Existe
hoje uma populacao de 279 individuos que slo monitorados
semanalmente pelos tecnicos da Associaqao Mico-Ledo-
Dourado (AMLD) (AMLD, 1998). A reintroducao do mico-
leao-dourado e um dos poucos casos de reintroducao bern
sucedidos. Grande parte do sucesso se deve a esforros ap6s a
reintroducqo para manter a sobrevivencia dos animals de
cativeiro at6 eles se reproduzirem na mata (Beck etal., 1991;
AMLD, 1998; Castro et al., 1998). Num "workshop" de
AnAlise de Viabilidade de Habitats e Populaq6es (PHVA),
realizado em 1997 (Ballou et al., 1998), foi colocado como
prioridade a compreensdo dos fatores que afetam a
sobrevivencia ap6s as reintroduq6es, e um dos fatores citados
foi a presenga do Callithrix jacchus, uma especie ex6tica, no
estado do Rio de Janeiro.

A partir de 1985 foi observada a presence de individuos do
sagiii (Callithrixjacchus) em fragments de mata nas fazendas
destinadas a reintroducao do mico-lelo. C. jacchus, originArio
do nordeste brasileiro, vemn sendo introduzido no estado do
Rio de Janeiro, resultado do trafico illegal de animals silvestres.
A ecologia desta esp&cie 6 parecida corn a dos micos-le6es e
por isso, poderiam ser competidores. 0 grau de competicqo
imposto por uma especie introduzida iri defender da
semelhanqa entire os nichos da esp&cie native e da exotica.

Observaq6es feitas pelos t&cnicos da AMLD indicam que C.
jacchus utiliza os comedouros colocados para os micos-le6es
e os acompanha durante o dia, sendo registrados
comportamentos agressivos (por exemplo, luta) e afiliativos
(por exemplo, brincadeiras) entire as esp6cies. Nio existem
dados quantitativos sobre o tamanho da populacao de C.
jacchus, grau de associaco entire as duas esp&cies e a
organiza:go funcional da associaiao.

0 objetivo deste trabalho foi estimar a distribuicgo de C
jacchus nas areas de ocorrencia do Leontopithecus rosalia e
tambem estimar a populacao de C. jacchus no maior
fragmento de mata com micos-le6es reintroduzidos.

Metodos

Foi verificada a ocorrencia de C. jacchus nas 15 fazendas com
micos-le6es reintroduzidos localizadas nos municfpios de Rio

Bonito e Silva Jardim no Rio de Janeiro. A amostragem
populacional foi realizada na Fazenda Rio Vermelho,
localizada no municipio de Rio Bonito (4235'W, 2243'S).
Esta fazenda foi escolhida como modelo por ter o maior
fragmento de mata (1.000 ha) e a maior populaqio de micos-
le6es reintroduzidos. No infcio do estudo esta fazenda possuia
10 grupos de micos-le6es corn um total de 65 individuos
marcados individualmente e com colares de telemetria (um
indivfduo por grupo).

Amostragem da populafdo
O levantamento da populacao de C. jacchus nas fazendas
destinadas a reintroduqio de micos-le6es foi feito atravds de
uma enquete aos t6cnicos da AMLD, que monitoram todas
as fazendas tres vezes por semana desde 1985. As respostas
dos tecnicos se basearam nos registros diarios do program e
percepq6es ou observaq6es pessoais da coordenadora, Andrdia
Martins (AMLD), a qual tern 15 anos de servico no projeto
de reintroducao.

A partir de outubro de 1998 comeqaram as captures mensais
para estimar o tamanho da populacao de C. jacchus na
Fazenda. As captures foram feitas usando entire 12 a 18
armadilhas tipo "Tomahawk" por grupo, cevadas corn ba-
nanas e colocadas em sete plataformas de capture. 0 esforqo
para capturar um grupo terminou no dia em que foram
capturados pelo menos a metade dos membros.

Os sagiiis capturados foram levados ao laborat6rio (localizado
em Rio do Ouro, Rio Bonito), onde foram anestesiados corn
Ketamina (sob supervisor do veterinArio C. Verona da
Universidade Estadual do Norte Fluminense) e marcados corn
tatuagem (na perna direita, corn a sigla do grupo e o ndmero
do mico). Os animals ficaram sob supervisor veterinAria ate
passar os efeitos do anest6sico, ap6s o qual foram devolvidos
ao lugar de capture.


A estimativa da populacso de C jacchus foi feita atravds da
contagem de todos os individuos marcados, representando o
numero minimo de sagiiis na Fazenda Rio Vermelho. Este
ndmero foi dividido pela area de mata para estimar a densidade
populacional mfnima (Cullen, Jr. e Valladares-Padua, 1997).

Resultados

C. jacchus esti amplamente distribuido dentro da Area de
ocorrencia do mico-leao. Das 15 fazendas corn micos-le6es,
sete contem sagiiis (Tabela 1). Destas sete, as cinco fazendas
mais ao sul (nas Areas de Rio Vermelho e Afetiva) jA tinham
sagiiis ao infcio das reintrodug6es (c. 1985), das fazendas mais
ao norte (Area de Santa Helena, nas fazendas Dois Irmaos e
Igarap6), os sagiiis foram avistados somente a partir de 1998
(Tabela 1). Foram avistados sagiiis na Reserva Biol6gica de Poqo
das Antas, mas nao na Reserva Biol6gica da Fazenda Unigo.

Os resultados indicam que a populacio de C. jacchus na Fazenda
Rio Vermelho esti maior do que a populacqo de L. rosalia. Fo-
ram marcados 90 individuos, provavelmente de nove grupos
socials, representando o ndmero mfnimo da populacqo
(densidade = 0,09 ind/ha), enquanto que a populaco de mico-
leao na Fazenda Rio Vermelho foi de 62 animals (densidade =
0,06 ind/ha). Foi observado que nos territ6rios de dois grupos
de micos-le6es (TRI, EST) havia pelo menos dois grupos de
sagiii, enquanto nos outros grupos (APP, RV) havia apenas um
grupo de sagiiis.

animals silvestres aumentou corn a construcio de rodovias
ligando os diferentes estados (Dean, 1995). A dispersao dos
sagiiis para a regiao centro fluminense provavelmente
intensificou-se corn a construcgo da BR-101 e a ponte Rio-
Niter6i. Atualmente, hi sete fazendas da reintrodugio de mico-
leao-dourado corn a presenca de sagiiis. Em 1985 o sagii estava
present apenas nos fragments de Rio Bonito (26 km distant
da Reserva Biol6gica Pogo das Antas) e na regiao da Fazenda
Afetiva (16 km de Poqo das Antas). Treze anos depois, em 1998,
os sagiiis apareceram nos fragmentos na regiao da Fazenda Santa
Helena, a 1 km de Poqo das Antas, com uma taxa de expansao
de 1,2 km/ano. JA em 2000, foram observados sagiiis no centro
educativo da Reserva Biol6gica Poo das Antas. A presenga do
sagui na reserve e a proximidade corn outras fazendas aumentam
o perigo de que esta especie possa vir a colonizar esses fragments
de mata onde os micos-le6es selvagens se encontram,
dificultando ainda mais a conservacqo dessa espdcie.

No maior fragmento de mata corn mico-le6es reintroduzidos,
a fazenda Rio Vermelho em Rio Bonito, a populacao de C.
jacchus esti maior que a dos micos. Hi pelo menos 10 grupos
de mico-le6es (0,06 ind/ha) e nove de sagitis (0,09 ind/ha) em
1000 ha de mata. As femeas de Callithrix possuem um alto
potential reprodutivo. Verificamos em nossas captures e
observaq6es na Fazenda Rio Vermelho, a presenca de femeas
grividas e lactantes em todas as estaq6es do ano, ji o mico-lelo
s6 teve filhotes no perfodo de setembro a marqo. 0 alto potential
reprodutivo do sagiiis pode ser uma das causes da ripida
expansio da especie pelo estado do Rio de Janeiro.

A associaqao entire especies de primatas simpitricos e corn habi-
tats similares, tem sido documentada em florestas amaz6nicas,
onde as associa6es parecem trazer beneficios mdtuos (Garber,
1988; Heymann, 1990; Peres, 1992; Lopes e Ferrari, 1994).
No entanto, a assodaco de primatas nativos e ex6ticos & pouco
estudada, e essa aparente associa.,o poderia resultar em
competiqdo por recursos e troca de parasitas entire as duas
especies e, portanto um obsticulo para a conservacao do
Leontopithecus. Os Leontopithecus e os Callitrhix sdo simpitricos
somente nas florestas do norte da Bahia. Na Reserva Biol6gica
de Una, L. chrysomelas e o C. kuhlii se associam corn pouca
freqiiuncia e esta esp&cie parece explorer o Leontopithecus (Ruiz-
Miranda, obs. pess.). Na Fazenda Rio Vermelho, o indice de
associacao entire C. jacchus e os L. rosalia chega a 65% durante
o inverno, e a presenqa do C. jacchus muda o comportamento
dos L. rosalia reintroduzidos (Affonso et al., no prelo).

Podemos concluir que o sagiii e um factor de importincia para
a conservaco do mico-leao-dourado. Antes de qualquer media
de manejo da populacao dos sagiiis, e necessirio mais estudos
para determinar ate que ponto essa possivel sobreposicao de
nichos poderi prejudicar o restabelecimento do mico-leio-
dourado em seu ambiente natural e saber como a dispersio
desta especie pelas fazendas esti ocorrendo, pois a presenca de
um ex6tico competitor e essencial para considerar futuras ireas
de reintroducao (Kleiman et al., 1990).

REPATRIATION OF TWO CONFISCATED BLACK HOWLER
MONKEYS (ALOUATTA PIGRA) IN BELIZE

Robin C. Brockett
Bruce C. Clark

Introduction

The Belize Ministry of Natural Resources formally approved
the establishment of the Wildlife Care Center of Belize (WCCB)
in October 1996. Located within Monkey Bay Wildlife Sanc-
tuary (MBWS), the WCCB's goals are:

1. Maintain confiscated wildlife and evaluate suitability for
re-release.
2. Explore suitable options for non-releasable wildlife.
3. Conduct Monkey Bay National Park habitat surveys and
post-release wildlife monitoring, for example, see Clark
and Brockett, 1999.
4. Research, develop and document rehabilitation techniques
for this location.
5. Provide training opportunities for Belizean students and
conservation personnel.
6. Collaborate with governmental and non-governmental
organizations on public awareness programs.
7. Publish data in relevant scientific journals.

In February 1998 the Conservation Division of the Forest
Department of Belize confiscated an eight-month old, female
black howler monkey (Alouattapigra). She was in the posses-
sion of a private individual residing in the Cayo District. Fed a
market diet with limited veterinary care and obviously human-
ized, she was presented to the WCCB at five pounds and in
surprisingly good health. She was immediately placed in a small
holding pen and allowed out for exercise three times daily. In
March 1998 an estimated eight-month old male was similarly
acquired, originating from the Belize District. This animal was
fed rice, powdered milk, fruit and occasional native browse.
He was of reasonable weight at five pounds, but was lethargic
and displayed chronic diarrhea. This animal was maintained
in visual proximity of the newly acquired female. Both animals
accepted market produce and native browse immediately.

The pair were gradually introduced over a period of several
days of visual and limited physical contact, and only after fecal
checks proved negative. Diet consisted of various market and
native fruits and approximately 35 native browse species cut
and presented three times daily by the first author. Over time
fruits were reduced, but never eliminated, to induce browse
foraging.

Based upon the methodology of the howler translocation from
CBS to Cockscomb (Koontz et al., 1994), two negative TB
tests were conducted three months apart. Chemical
tranquilization with Telazol (Tiletamine/Zolazepam, 100 mg/
ml, Fort Dodge Animal Health, Fort Dodge, Iowa, USA) was
administered the second time to permit a thorough examina-

tion and to insert a permanent metal identification ear tag.
Radio collaring was not an option due to the size of the ani-
mals. Fecal samples were performed periodically throughout
the fifteen months of captivity with all but one sample prov-
ing negative. Ascarids were found in one sample and treat-
ment with Pyrantel (pyrantel pamoate, Pfizer, Inc., US Ani-
mal Health Operations, 235 E. 42"n Street, New York, NY)
cleared the condition. Weights were monitored throughout
the captive phase. Early on, the male was found to have suf-
fered a break of the left tibia, thought to have been caused by
his poor diet. Full use of the limb was eventually regained.
Botfly infestations are relatively common in wild populations
and generally do not result in problems. Both animals were
treated with Ivermectin (Ivomec, 10 mg/ml, Merck AgVet
Division, Merck & Co., Inc., Rashway, New Jersey, USA)
when larvae counts reached 5 per animal. In December 1998
the male presented an approximately 40% hair loss, thought
to be attributed to botfly bites. Skin scrapings were negative
and the scratching eventually subsided with treatment of Pred-
nisone (Prednisolone, Merck, Sharp and Dohme, Division of
Merck and Co., In., West Point, Pennsylvania, USA).

Pre-release Training

In September 1998 the animals were moved to an enclosure
to encourage native browse foraging, exercise and to dehu-
manize. This enclosure contained native trees, surrounded by
137 meters of electrified nylon mesh measuring one meter in
height (Fast-Fence Net, WV Fence Corporation) and charged
by solar-power. A small holding-cage measuring 1.8 x 1.8 x
2.4 m was placed inside to allow supplemental feeding and
aid in recapture. Supplemental feedings were gradually re-
stricted. Containerized water was available continuously, al-
though animals were observed early on drinking off leaves
and from tree crotches. A swath was kept dear surrounding
the charged fence for a distance of five meters. This contain-
ment method has proved effective for howlers, which are not
adept jumpers and do not brachiate. The animals were condi-
tioned to a clicker to signal feeding with the presumption
that predictable entering of the feeding cage would aid in re-
capture. Furthermore, clicker training would help to locate
the animals once released. A total of 300 observational hours
were conducted during the survival training portion of this
program.

Release Methodology
Published behavioral, ecological and translocation data helped
to develop criteria supporting the highest expectation of sur-
vivorship for this program (Brockett, unpubl. obs.; Brockett
etal., in press; Ostro etal., in press; Ostro etal., 1999; Silver
et al., 1999; IUCN, 1995a; IUCN, 1995b; Horwich et al.,
1993; Horwich and Lyon, 1990; Griffith etal., 1989; Neville
et al., 1988; Horwich and Johnson, 1986; Horwich, 1983;
Haarthorn, 1982; Konstant and Mittermeier, 1981). Criteria
included:
1. Minimum of two familiar and unrelated animals will be
released together for predator avoidance, sociality,
foraging success and observation conspicuousness.


2. Animals must be behaviorally sound, physically adept
and able to identify natural food sources.
3. Veterinarian supported health screenings including fecal
floats and TB negative. Identification markers must be
apparent for observational follow-up.
4. At least one animal must be two or more years old. Wild
individuals disperse at that age.
5. The re-release area must be protected, have habitat
capable of supporting howlers and be of low howler
population density. An acclimatization period must be
maintained in a natural setting minimizing human
dependence and contact.
6. Soft-release methodology must be employed.

Release
In May 1999 the howler pair were relocated to a pre-se-
lected wild release site located deep within MBNP They were
placed in a 2.4 cubic meter holding cage and fed favored
fruits and native browse three times per day for a total of
four days to acclimate to the new location. Some human
contact was maintained to ensure a reasonable prediction of
re-entry into this cage if necessary.

On Day four within MBNP, the animals were released dur-
ing early morning. They immediately ran along the ground
for approximately 10 m before heading up into trees. Main-
taining continual visual or auditory contact with each other,
within five minutes they located a native fruit tree. Three
hours post-release, the animals were enticed back into the
holding cage with the clicker, fed fruits and locked in over-
night. This scenario was repeated for two additional days
when, on the third day, they refused to re-enter. Supplemen-
tal feedings were offered three times per day. The animals
refused altogether the browse presented. An increasing re-
luctance to accept more than one fruit feeding or to descend
below 2.4 m of the ground quickly became apparent. Within
fourteen days of release they became unresponsive to the
clicker.

Behavioral analysis
Post-release data were collected from sunrise to sunset daily
on behavior and ranging. Approximately 150 field-hours were
documented between 30 May and 8 July 1999. A follow-up
paper will be drafted documenting comparative behavior pre-
and post-release. During Week five, a wild adult male joined
the pair and remained in immediate proximity for 14 days.
The rainy season began in earnest and flooding of the site
made further access impossible. Within 14 days, the rains
subsided and re-contact was attempted. On three separate
occasions vocalizations were heard, yet the animals were not
observed. After cutting and mapping new trails to the pre-
sumed location of the vocalization, re-contact was not con-
firmed. On 16 October, three unrelated howlers were observed,
an adult male and female with one juvenile male. The next day
this trio was observed in proximity of the repatriated pair.
However disappointing it was to have missed this group for-
mation, follow-up observations determined that this newly
formed group of five animals has maintained habitual contact.

Discussion

It is believed that neither of the confiscated howlers had been
with conspecifics for two-three months prior to introduction.
The immediately successful introduction appears to be a result
of an age-specific response. The primary author observed simi-
lar-aged, yet unfamiliar wild animals interacting, while adults
of each group looked on. Eight months old is perhaps an ideal
age for introductions. Additionally, these animals were prob-
ably juveniles rather than infants upon initial capture judging
from their acceptance of a natural diet and the demonstration
of appropriate predator responses. As of this writing, additional
release candidates have been relocated to the WCCB. Primate
surveys in surrounding areas of MBNP are planned.

ATTEMPTED PREDATION ON A WHITE-FACED SAKI IN
THE CENTRAL AMAZON

Kellen A. Gilbert

During a survey of primates in a 100-ha isolated forest frag-
ment, a crested eagle (Morphnus guianensis) attacked a young
female white-faced saki (Pitheciapithecia). The forest fragment
is one of the reserves of the Biological Dynamics of Forest Frag-
ments Project (BDFFP) located about 80 km north of Manaus,
Amazonas, Brazil. This area of the central Amazonian basin is
upland terra firme moist forest (Bierregaard et al., 1992). Six
primate species, Ateles paniscus, Alouatta seniculus, Cebus apella,
Chiropotes satanas, Pithecia pithecia, and Saguinus midas are in
the reserve area, but only groups ofA. seniculus, P. pithecia, and
S. midas inhabit this 100-ha reserve (pers. obs). Potential avian
predators of monkeys observed in the reserve area include
Harpia harpyja, M. guianensis, and Spizeatus ornatus (Cohn-
Haft et al., 1997).

At 11:07, while conducting a primate survey, about 30 meters
from the edge of the reserve, I observed a P pithecia group. I
counted three individuals; an adult male, an adult female, and
a smaller female. The male was on a large horizontal branch




104 Neotropical Primates 8(3), September 2000


about 15 m above the ground, looking about while pacing
and making a low chuck vocalization. The females were to-
gether about 10 m from the male. They appeared agitated
and moved closer to the male as I observed. At 11:09 a large
raptor flew from the interior of the reserve toward the group.
The bird, a crested eagle, swooped down into the tree where
the younger female was last seen. There was a loud screaming
vocalization by the female and a loud sound of breaking
branches. The attack took less than ten seconds. The eagle
then flew at midstory toward the edge of the reserve. Imme-
diately after the eagle left, the adult male saki returned to the
location of the attack and appeared piloerected. The adult
female then moved closer to the male and both left the area
silently. I did not observe the eagle with the saki, nor did I
find the body of the juvenile female. I did not see the younger
female again however on repeated surveys of the group.

This is the first reported observation of an avian attack on P.
pithecia. Crested eagles prey on a variety of small to medium-
sized mammals. At a crested eagle nest in one of the BDFFP
reserves, Bierregaard (1984) found the remains of small ro-
dents, marsupials and two kinkajous (Potosflavus) whose adult
weight is approximately 2.6 kg (Fonseca et al., 1996). Julliot
(1994) observed a crested eagle take a six to eight-month old
spider monkey in French Guiana. An adult white-faced saki
weighs approximately 1.5-2.25 kg (Buchanan et al., 1981).
An immature individual, weighing closer to the lower end of
the range, could be a likely prey item for a crested eagle.

Buchanan et al. (1981) reported that a captive juvenile P.
pithecia displayed an alarm reaction of freezing without vo-
calization when exposed to large bird silhouettes and to the
overhead movement of large objects. This behavior is in con-
trast to the agitated behaviors of the sakis observed in this
case. The saki group in the reserve was not habituated, so the
reaction observed may have been due to the presence of the
observer.

Observations of predation and attempted predation on pri-
mates are rare. In the neotropics, harpy eagles have been the
most common predators observed to take immature and adult
howling monkeys (Rettig, 1978; Eason, 1989; Peres, 1990;
Sherman, 1991). Peres (1990) reported secondhand but reli-
able observations of harpy eagle predation on sakis and other
primate species in Amazonia. The crested eagle needs to be
considered a significant primate predator as well. Informa-
tion on predation is needed for a more comprehensive exami-
nation of the constraints on free-ranging primate sociality. It
is also important to note that the isolation of forest fragments,
in this case, did not eliminate a large avian predator.

INFANTICIDE FOLLOWING IMMIGRATION OF A
PREGNANT RED HOWLER, ALOUATTA SENICULUS

Erwin Palacios

Red howler monkeys are among the several primate species
showing male and female transfer (Crockett and Eisenberg,
1987; Glander, 1992; Crockett and Pope, 1993). Neverthe-
less, this emigration pattern differs from most polygynous
primates in that red howler immatures of both sexes emi-
grate from natal groups (Crockett and Eisenberg, 1987),
with females rarely succeeding in entering and breeding in a
previously established troop (one that has produced offspring)
(Crockett, 1984; Crockett and Pope, 1993). One of the facts
preventing female immigration into an established troop is
the aggressive attitude adopted by female residents. This is
indeed a manifestation of the complex behavior identified




Neotropical Primates 8(3), September 2000 105


to mediate the emigration of some females. Female-female
reproductive competition in this species appears to be di-
rected at limiting the number of reproductive positions in a
troop, and hence maintain small troop size (Crockett and
Pope, 1993; Crockett, 1996).

Recently, a new hypothesis has pointed out infanticide as
the most reasonable fact to explain small troop size in red
howlers (Crockett and Janson, 1993, 2000). Infanticide has
been well documented in red howlers (Rudran, 1979;
Crockett and Sekulic, 1984; Izawa and Lozano M., 1994;
Agoramoorthy, 1994; Crockett, 1998), and it is associated
with male invasions of established groups, or within group
male status changes, in order to gain access to reproductive
females. By killing infants, males reduce the time to the
mother's next conception.

During 1996, Istudied the diet and ranging patterns of a group
of red howler monkeys at Caparn Biological Station (1'5.55'S,
69"30.8'W), lower Rio Apaporis River, Colombia (Palacios,
1997, 1998; Palacios and Rodriguez, in review). I observed
the group from January to December. The group was usually
contacted for 3-5 days per month. At the beginning of the
study, two adult females, one subadult female, an infant fe-
male, and three males (adult, juvenile and infant) composed
the study group. The adult male was the same individual dur-
ing the entire study period. I was able to recognize him by his
particular facial physiognomy, and a little scar on his upper lip.
This male was observed in the same group on November 1997,
and on several additional occasions afterward.

Female immigration

On April 1, 1996, the group was moving to the western
border of their home range, and arrived at a Couma
macrocarpa tree (#84) (about 200 m away from the home
range's border), where they spent 19 minutes feeding on
ripe fruits. This part of the home range is located about 80-
100 m from the highest water level of the Taraira Lake, and
is deluged by small creeks flowing into the lake. The forest
growing in this area is very low and shrubby, and heavy ar-
boreal animals such as red howlers must circumvent it.

After feeding in tree #84, with the adult male leading the
progression, the group moved 150 m to the west, going
around the low vegetation area, and stopped for a moment.
The adult male grunted, and then all the group members
but the adult male moved back (i. e., to the east) around the
low vegetation area, but following its southern border, until
arriving at tree #85 (Maquira guianensis) where they began
another feeding bout.

While the group was moving back, the adult male repeat-
edly grunted and then hid in the canopy. I kept contact with
the rest of the group, waiting for the male to join the troop
later. Ten minutes after the troop began to feed on tree #85,
the adult male and a new female (that I had not observed
before) moved toward the Maquira tree. The male grunted


twice, entered the tree with the female, and both began to feed
with the other troop members. Female residents showed no
aggression towards the female immigrant at that time, nor on
the three subsequent days of observation in April.

Infant killing

In early May the immigrant female was observed with a new-
born male (28 days old, according to our last date of contact
with the group). On May 2, after feeding for a long time on
tree #121 (Couma macrocarpa), the group moved in the linear
fashion progression typical of red howlers, with the immigrant
female being the closest one to the adult male, which was fol-
lowing them. At 2:52 h the adult male rapidly approached the
immigrant female and attacked her, causing her to fall about
16 m to the ground. The adult resident females were about 20
m ahead, and rapidly returned. While they approached, the
female climbed to a tree, where the male attacked her again,
and roughly took away her little infant. The male moved to an
adjacent creek area, where I was not able to observe him due to
dense foliage and vines. I could not detect if the infant fell
down, probably because of his very light weight. It was also
possible that his small body remained wedged within the
branches and dense vines.

Five minutes after this episode the group continued moving,
with females in front and continuously grunting. The immi-
grant female was piloerected and clearly frightened by the male,
which moved behind her, also grunting repeatedly. Thereafter,
the group engaged in three feeding bouts on three different
trees. The male participated in all but one. When he was not
feeding, he remained watching the rest of the group from a
neighboring tree, and continuously grunted. Some minutes
later, when the group was feeding on young leaves at tree #116
(unidentified Fabaceae), the two adult female residents chased
and expelled the adult male from the tree, when he approached
where the immigrant female was feeding. Later the group ar-
rived at sleeping tree #19, this tree had been used by the group
before, and although they usually formed two or three sub-
groups (adult male always alone), the animals used to rest rela-
tively close to each other (6-10 m apart), the animals entered
the tree, adult male being the last one, and all but the male
settled down to rest. The male moved to an adjacent tree, ten
minutes later returned to the sleeping tree, and then he settled
about 15 m away from the rest of the group, already resting in
three different groups very close together (3-6 m apart). The
next morning the male was observed resting in an adjacent
tree, while the rest of the group remained in the sleeping tree.
On the following two days, female residents displayed aggres-
sive attitudes towards the male on three occasions, all in a feed-
ing context. Over the next two days, the male repeatedly ap-
proached the immigrant female, but she always fled. On the
second day, while the troop was moving, the immigrant female
jumped between two trees, and the male grabbed her by the
tail, pulled her towards him and mounted her. Copulation lasted
119 s. I did not observe further copulation bouts until the end
of the study period (December 15, 1996).

Discussion

Red howler females may emigrate from natal groups because
ofwithin-group competition for breeding positions (Crockett,
1984, 1996). After dispersal, they attempt to join a troop in
which to breed, but are more likely to succeed in joining a
newly-formed troop and rarely enter established troops. In
the present study, the troop composition included a juvenile,
suggesting that it was not newly formed. No cases of female
emigration in red howlers to date (Crockett, 1984, 1996;
Crockett and Pope, 1993) have reported on emigrating preg-
nant females. On the contrary, this could be possible in
mantled howler transient immigrant females (Glander, 1992).
It is uncertain whether the immigrant female became preg-
nant in a newly formed troop that failed and broke up or in
her natal group.

Successful red howler immigration into established troops is
very infrequent (Crockett, 1984). By showing an aggressive
attitude towards immigrants, female residents limit reproduc-
tive female membership to four (Sekulic, 1982; Crockett,
1996). The howler group at Capard had only two adult fe-
males, both rearing infants, and a subadult. No aggressive
attitudes were observed between resident and immigrant fe-
males, probably because female membership positions were
not fully occupied. Nevertheless, it is uncertain whether resi-
dent females were able to detect the immigrant female's preg-
nancy, and whether this affected their decision. Glander (1992)
described how mantled howler females joined established
groups; males do help extragroup females entering a group,
and once a female achieves entry into a group this way, it is no
longer chased by the resident females and becomes a group
member. The male's explicit acceptance of the new female is
in accordance with Glander's observations, and could be con-
sidered as a definite fact leading to the extragroup female's
success in entering the group.

Infanticide of infants born to pregnant females some time
after entry of new males was reported by Crockett and Sekulic
(1984). These observations and my own are consistent with
the hypothesis that males can remember which females they
mated with. Infanticide in red howlers has always been re-
ported as a consequence of male status changes, whether this
occurs by male takeovers, or changes within a troop. This is
the first report on infanticide not associated with a male sta-
tus change, and, regardless of the context in which it occurred,
was related to the same benefit that infanticidal males seek
after taking over a group or deposing a male of their own: a
reproductive advantage by having access to a reproductive fe-
male. Nevertheless, this did not represent an immediate profit
to the male, nor to the immigrant female; no new infants of
the immigrant female were observed during the rest of the
study period. I observed a new infant on November 1997,
belonging to one of the adult female residents. This clearly
agrees with Crockett's (1984) proposed costs of emigration;
although the immigrant female succeeded in entering an es-
tablished troop, she did not breed successfully (paying a high
cost losing her infant) and, very likely, delayed her age at first,
successful breeding. The latter could also be affected by the


fact that the other two infants (about eight and nine months
old) in the group disappeared during June-July 1996 (prob-
ably because of food shortage or predation), leaving the male
free to mate with any of the three reproductive females.

Introduao


As doencas parasitirias sio responsiveis por considerdvel
morbidade e mortalidade em todo o mundo, e
freqiientemente estao presents com sinais e sintomas nao
especfficos. A recent descoberta de uma serie de agents
infecciosos, inclusive definindo quadros clfnicos ate entgo
nao descritos, bem como a crescente expansio de doengas ji
conhecidas, tem feito ressurgir o debate sobre a importrncia
das doengas infecciosas e parasitarias (DIPs), mesmo nos
pauses de primeiro mundo (Berkelman, 1994). Yamashita
(1963), em estudos parasitol6gicos com primatas do genero
Alouatta detectou a presenga de Mathevotaenia megastoma,
Anchylostoma mycelis, Longiastriata dubis, Enterobius minutus,
Dipetalonema atelenses, Microfilaria sp., Controrchis
biliophilus, Filariopsis aspera, Raillietina demerariensis, Railli-
etina multistesticulata, Squanema bonnei e Raillietina
alouattae. Martins etal. (1997) encontraram ovos de parasitas
em 33% das amostras de fezes de Alouatta guariba, porem
nio as identificaram. Luz et al (1987) encontraram cistos
de Entamoeba coli, E. histolytica, Taenia sp. e Strongiloides
sp. em fezes deAlouattaguariba. Quanto a anatomia do trato


digestive, o genero Alouatta possui est6mago avantajado,
intestino curto, mas espacoso, com fermentacao bacteriana.
Quanto a dieta, slo folivoros comportamentais, possuindo
seletividade quanto ao alimento, apresentando organizagco so-
cial, locomocao e nfvel de atividade que os torna adaptados k
sua dieta (Milton, 1977). A esp&cie Alouatta guariba, descrita
na regilo hi 70 anos, encontra-se ameacada devido a devastaqdo
da mata, aao de predadores e caga. Por isso, surgiu hi sete
anos o interesse pelo desenvolvimento de estudos cientfficos
sobre o comportamento e hibitos destes animals, por professors
e academicos da Universidade Regional de Blumenau, Santa
Catarina, corn a finalidade de subsidiary as a96es de preservagio.
O estudo de endoparasitoses intestinais em primatas no Brasil
e bastante escasso, mas de extrema importncia principalmente
em populac6es que ocorrem em ambientes fragmentados, como
So caso da Mata Atldntica em Indaial, Santa Catarina.

M6todos

As coletas foram realizadas no perfodo de julho de 1998 k marco
de 1999, sendo avaliados oito animals machos e duas femeas
de diferentes faixas etarias, mantidos em cativeiro durante e
p6s quarentena, totalizando 165 amostras. A coleta de mate-
rial de animals foi realizada semanalmente, no perfodo da
manha, as fezes coletadas em frascos plisticos descartiveis
contend conservante SAF (920ml de soluqlo fisiol6gica
0,85%, 50ml de Scido acetico glacial, 30ml de formol e 5ml
de glicerol). Durante o trajeto do CEPESBI-Centro de Pesquisas
Biol6gicas de Indaial, Santa Catarina (local de coleta) atd o
laborat6rio, as amostras foram mantidas em conservante, dentro
de caixa de isopor evitando calor excessive e conseqilente
deterioracao de alguns organismos. A pesquisa e identificaqko
dos parasitas foi realizada atraves de dois diferentes metodos:
Metodo de Faust y Cols.-centrffugo flutuaqao em sulfato de
zinco 33%; e Sedimentacao Hoffmann -sedimentagco
espontinea das fezes em agua (Moraes, 1984 e Pessoa, 1988).

Resultados e Discussio

Aldm dos resultados apresentados acima, nos animals de
quarentena foram encontradas combinac6es de 5,46% de dois
tipos de parasitas (Giardia sp. e Enterobius sp.). Nos animals
de p6s-quarentena observou-se a mesma combinaqio de
parasitas, pordm com maior freqiiencia (11,52%).

Estes resultados devem-se, talvez, pelo fato de que os animals
de quarentena encontravam-se isolados em process de
aclimatamo, sendo que, no period p6s-quarentena os mesmos

encontravam-se em companhia de outros bugios, em contato
direto corn humans e animals domesticos. Silva etal. (1997),
em estudo com Alouatta guariba clamitans, identificaram seis
generos distintos de parasitas entire protozoarios e nemat6dios.
Os protozoirios representaram 17,87% de cistos de E. coli e
17,87% uma combinaqco deE. coli com E. histolytica. Dentre
os nemat6ides foram encontrados 22,42% de ovos e larvas de
ancilostomideos. Os primatas neotropicais sao hospedeiros de
uma grande variedade de parasitas, entire eles muitas especies
de nemat6dios que ocorrem em animals capturados na
natureza e em animals mantidos em cativeiro. Os primatas
Cebidae, sao altamente infectados por parasitas da famflia
Oxyuridae (Inglis etal., 1959 in Inglis etal., 1965). De acordo
corn Yamashita etaL (1963) foram encontradas 228 esp6cies
de helmintos, incluindo, 166 especies de nemat6dios, cinco
especies de acantocdfalo, 24 especies de tremat6dios e 33
especies de cest6dios em 103 especies de primatas. Sao poucos
os estudos parasitol6gicos relacionados diretamente ao Alouatta
guariba, seja em ambiente natural ou em cativeiro (Hirano et
al., 1997). No present estudo foram encontradas 23,64% de
ocorrencia de ovos, cistos e larvas nas amostras de fezes de
Alouatta guariba clamitans em cativeiro, coletadas durante e
p6s-quarentena.

Conclusio

A verificacqo de um maior percentual de parasitas p6s-
quarentena levou a constataqgo de que ocorrem contaminag6es
em cativeiro, as quais podem estar ligadas ao comportamento
alimentar dos animals, ao contato corn fezes, corn outros

DADOS PRELIMINARES SOBRE A ECOLOGIA DE
SAGUINUS NIGER NA ESTArAO CIENTfFICA FERREIRA
PENNA, CAXIUANA, PARA, BRASIL

Cecilia Veracini

Introduiio

Saguinus niger (E. Geoffroy, 1803) ocorre na Amaz6nia ori-
ental, sul do Rio Amazonas, leste dos Rios Xingi e Fresco,
atd o baixo Rio Araguaia incluindo o Arquipdlago do Maraj6
(Napier, 1976; Hershkovitz, 1977; Ferrari e Lopes, 1996).
Apesar de ser considerado relativamente comum (Rylands et
al., 1993), a sua ecologia e o comportamento na natureza
s-o ainda pouco conhecidos e, ate hoje ha somente um estudo
a long prazo; na area de Paragominas, no leste do Para
(Mendes de Oliveira, 1996).

0 present trabalho relata alguns aspects da ecologia
alimentar e da utilizagco de habitats de S. niger observado na

teresse do estudo na Floresta Nacional de Caxiuana 6 devido
a sua particular biodiversidade e grande grau de preservacao
(Almeida et al., 1993; Lisboa et al., 1997) em comparasco
corn outras areas da Amaz6nia oriental e, tambem, k presenca
de uma outra especie de calitriqulneos, Mico argentatus
(Linnaeus, 1771), pois a simpatria entire os g6neros Saguinus
e Mico se encontra de fato em limitadas ireas na Amaz6nia
(Ferrari, 1993; Lopes e Ferrari, 1994; Ferrari et al., 1997).

Area de Estudo e MWtodos

A irea de estudo esti localizada na Estacao Cientifica Ferreira
Penna, Caxiuani, pertencente ao Museu Paraense Emflio
Goeldi-CNPq, no Municipio de Melgaqo, Pard. Esta drea e
constitufda, em grande parte, de floresta de terra firme e
abrange parties inundadas de igap6 e formaq6es de
crescimento secundirio (capoeiras), corn idades estimadas
em 3, 10, 25 e 40 anos, respectivamente, e altura media de 5
atr 15-18 m, na dpoca do estudo. As capoeiras incluidas na
area de uso do grupo estudado compreendiam 10,5 ha, e as
dreas inundadas aproximadamente 6 ha (para a descricgo
floristica da drea ver Lisboa et al., 1997). Para estudar a
utilizacao dos diferentes habitats foram consideradas as areas
de transicqo (10 m de passage entire habitats primirios e
secundrios).

Na drea de estudo foi identificada a presenqa de um minimo
de trrs grupos sociais de S. niger. Para o estudo foi escolhido
um grupo constituido de tries individuos cuja a composigco
various ao long da pesquisa, passando a quatro individuos e
depois a cinco nos dltimos dias de observacio. Foram abertas
trilhas em sistema de quadrantes (50 x 50) de acordo corn a
drea de vida do grupo. Observac6es nao sistemrticas foram
feitas sobre os tres grupos sociais de S. niger em janeiro e
fevereiro de 1996, enquanto o grupo de estudo foi habituado
ao observador. Outros dados ad libitum (Altmann, 1974)
sobre a alimenta coletados durante o estudo da espdcie simpstrica C. argentata
de janeiro a novembro de 1996 (Veracini, 1997). Dados
quantitativos foram coletados nos meses de marqo, abril,
julho, agosto e novembro de 1996, para um total de 80 horas
(1.904 registros, 909 amostragens) distribuidas ao long
destes meses, corn os animals sendo acompanhados em
diferentes moments do dia. 0 m6todo usado foi a varredura
instantinea ("instantaneous scan sampling", Altmann, 1974)
corn intervalos de cinco minutes por um minuto de amostra
instantinea das atividades (Ferrari e Rylands, 1994). Em cada
amostragem era anotado: a categoria comportamental
(alimentagio, forrageio, locomocao, descanso, atividade so-
cial), a altura (quando possivel) de cada animal avistado e o
tipo de habitat que o grupo ocupava. Em combinaqIo,
utilizou-se o registro de todas as ocorr8ncias para a capture
de press animals e utilizacIo de frutos e outros materials
vegetais. As irvores utilizadas para a alimentacgo foram
marcadas e mapeadas para uma identificago sucessiva. Todos
os frutos consumidos foram coletados e conservados em alcool
a 70%. Os dados climatol6gicos gerais da drea e do ano de
1996 foram obtidos na estacgo metereol6gica da ECFP
(Carvalho et al., 1997).

Resultados

Alimentafdo
A dieta do grupo de estudo foi constituida principalmente de
itens vegetais (frutos maduros, nectar e exsudados vegetais).
Nos meses de estudo os registros de itens alimentares foram
336 em 1904 registros (Tabela 1). Os components vegetais
da dieta foram 95,5%, enquanto que as press animals
vertebrados e invertebrados, constituiram 4.5% dos registros
alimentares. A fruta foi o alimento mais consumido corn
48,81% dos registros de alimentacao. 0 nectar e a goma fo-
ram 22,32% e 23,81% respetivamente.

Utilizapdo de recursos vegetais
S. niger utilizou os frutos de 46 tixons diferentes e o nectar de
quatro especies (Tabela 2), para um total de 22 families
diferentes. As mais representadas foram Sapotaceae,
Mimosaceae e Burseraceae. A maior diversificagio na utilizaqAo
dos frutos ocorreu na estaglo da chuva (janeiro-junho). Neste
perfodo, a fruta constituiu a maior part da alimentacao dos
animals, e os tixons mais importantes por ndmeros de registros
foram: Manilkara amazonica e Tapirira guianensis,
respectivamente 7,1% e 5,91% do total dos registros de
alimentacqo corn vegetais. Nos meses de julho e agosto, trhs
especies de frutos se destacaram (Byrsonima aerugo, Goupia
glabra e Inga lateriflora) constituindo 17,39% do total dos
registros de alimentacao com vegetais. As parties dos frutos
consumidos eram em sua maioria mesocarpos e arilos, nio
sendo observada a predacqo de sementes. As observaq6es
quantitativas e adlibitum indicam que os exsudados vegetais e
o nectar constituiram importantes recursos sobretudo em
perfodos de maior escassez de frutas. 0 grupo utilizou os
exsudados de oito tAxons (Tabela 3) e foi observado
freqiientemente comendo a goma dos orificios produzidos pelo
C argentata em arvores de Parkia ulei e Tapirira guianensis. Os
exsudados mais utilizados foram da especie Parkia ulei (7,78%
do total dos registros de alimentaqIo corn vegetais) e a
concentraggo das atividades do grupo ao redor destas arvores
no mes de julho foi um aspect relevant do comportamento.
O consume de ndctar aumentou nos 6ltimos meses da pesquisa
(de agosto ate novembro); neste periodo 50% dos registros de
alimentacao corn vegetais foram de ndctar, principalmente Inga
alba e Symphoniaglobulifera. No mes de novembro o nectar de
Symphonia globulifera constituiu 69,8% do total dos registros
de alimentacao corn vegetais naquele mes.

Atividade de forrageio
A atividade de forrageio (procura de insetos e outras press
animals) ocupa de 16% ate 45% das atividades do genero
Saguinus (Snowdon e Soini, 1988). 0 grupo de estudo em
Caxiuana dedicou 18,86% (n = 359) do tempo total de
observacio nesta atividade (Tabela 1). S. niger foi observado
procurando press animals em varios substratos e microhabi-
tats (sub-bosque aberto, copa das irvores, Area de margem
com densa vegetacao), chegando a seguir as press no chio,
mas principalmente nas copas das irvores do baixo-midio
estrato da floresta. Na busca das press, a intense observacgo
do meio pareceram mais important do que a manipulacio
dos substratos. A altura mais utilizada para esta atividade foi
entire 6 e 15 metros (72% dos registros, Fig. 1). Nao houve
uma preferencia significativa na utilizacio de Areas primArias
(terra firme e igap6) e secundirias (capoeiras e Areas de
transiqio) durante a atividade de forrageio: 35,65% desta
atividade ocorreu em floresta primria de terra firme, 37,61%
em Areas de capoeira, 15,04% em areas de transigio e 11,7%
no igap6. No geral, foi dificil observer as press dos saguis e
somente as maiores foram identificadas (dois fasmideos, umrn
mant6ideo, quatro ort6pteros). Foi observada somente uma
capture de um vertebrado; uma perereca (Classe Anura).

Utilizacdo de habitats
0 grupo de estudo utilizou uma area de vida de 35 ha, mas o
tamanho e provavelmente maior uma vez que o grupo saiu
vxrias vezes da parte demarcada. Houve sobreposidio de Area
entire os diferentes grupos e nio foi identificada uma parte de
uso exclusive do grupo. Foram observadas muitas interag6es
agonisticas entire os grupos socias, sobretudo na epoca da chuva
perto das irvores de fruta. Nos cinco meses de estudo
quantitative, o grupo de estudo utilizou a capoeira em 38,6%
do tempo (a capoeira de tries anos de idade nao foi frequentada),
a terra firme em 46,24%, o igap6 em 6,42% e as Areas de
margem por 8,74% do tempo. 1 provivel que as freqiiUncias
no igap6 e, talvez na terra firme, sejam subestimadas devido a
maior dificuldade de encontrar e observer os animals nestes
habitats. Na 6poca da chuva as observagoes no igap6 foram
quase impossiveis pelo alto nfvel da dgua e houve dificuldades
na terra firme, onde as alturas utilizadas eram freqiientemente
superiores a 20 m, em seguir um grupo de somente tres
indivfduos. A utilizacao dos diferentes habitats pareceu seguir
urn padrio sazonal correlacionado com a disponibilidade dos
recursos vegetais (por exemplo o igap6 foi muito freqiientado
no final da estaqlo seca em correspondencia com o abundant
consumo do nectar de Symphonia globulifera), mas no total
nio houve diferenga significativa entire o uso dos habitats
primirios e secundArios. S. niger foi ativo em todos os estratos
da floresta, utilizando, as vezes, alturas superiores a 30 m, mas
foi observado sobretudo (68,3% dos registros) na parte mddia
da mata de 6 at620 m (Fig. 1). A media das alturas dos substratos
utilizados foi de 15,5 m.

Discussko

Estudos precedentes sobre a alimentaqgo do genero Saguinus
relataram uma dieta de frutos, nectar, exsudados vegetais,
fungos, casca de irvores, press animals invertebradas e


vertebradas (Sussman e Kinzey, 1984; Snowdon e Soini, 1988;
Garber, 1993). Os frutos foram os components mais
consumidos por S. niger em Caxiuani, assim como o observado
no estudo em Paragominas sobre a mesma especie, onde os
frutos foram 87,5% dos itens alimentares (Mendes de Oliveira,
1996). As families mais utilizadas pelo grupo de estudo
(Sapotaceae, Mimosaceae, Burseraceae, Guttiferae) foram
tambem observadas na dieta de outras esp6cies (Snowdon e
Soini, 1988; Garber, 1993; Peres, 1993b; de la Torre et al.,
1995) e na especie S. midas (Mittermeier, 1977). Em
comparaqIo corn o grupo estudado em Paragominas, o ndimero
de tAxons vegetais na alimentacao foi muito maior (59 contra
18), indicando que a dieta de S. niger e dependent da
disponibilidade e diversidade ambiental mais que de uma
preferencia especie-especifica.

Urn intenso uso de nectar ji havia sido observado em outros
Saguinus amaz6nicos (Janson et al., 1981; Terborgh e Wilson,
1983; Egler, 1992; Peres, 1993b). 0 ndctar de Symphonia
globulifera demonstrou ser um recurso important na dieta de
S. niger sobretudo na 6poca menos chuvosa do ano, quando ha
escassez de frutos nas florestas de terra firme. As Areas inundadas
de Caxiuana (onde se encontra uma alta densidade de Symphonia
globulifera) chegam ao pico reprodutivo em terms de flares e
frutos em novembro, e podem servir como sftios alternatives
de alimentaqio para mamiferos e aves.

O consumo de exsudados vegetais e bastante comum entire os
calitriquideos e fundamentalmente sazonal para a maiora das
especies do genero Saguinus (Terborgh, 1983; Soini, 1987; Peres,
1993b). 0 uso de exsudados nao foi descrito em S. midas por
Mittermeier (1977) e Kessel (1995), embora A. Rylands
observou a ingestgo da goma produzida espontineamente das
vagens de Parkiapendula por essa espdcie nas reserves do Projeto
DinAmica Biol6gica de Fragmentos Florestais, ao norte de
Manaus em 1982-1983. Mendes de Oliveira (1996) tamb6m
relatou o uso de gomas de Parkia pendula por S. niger em
Paragominas (3.1% dos registros alimentares). Para S. niger,
em Caxiuani, os exsudados parecem ter um papel mais

important, seja em terms de um maior numero de tAxons
explorados seja de urn maior consumo em porcentagem. Al6m
das fontes de exsudados provenientes de frutos, ou das les6es
de insetos, ou de outros agents, os saguis fizeram um grande
uso da goma proveniente dos orificios abertos pelo C. argentata
em irvores de Parkia ulei e Tapirira guianensis, comportamento
observado pela primeira vez nesta espdcie. Este fen6meno de
parasitismo (Snowdon e Soini, 1988) foi reportado em outros
casos de simpatria entire as especies Callithrix emiliae e Saguinus
fuscicollis weddelli (Lopes e Ferrari, 1994) e S. fuscicollis e
Cebuellapygmaea (Soini, 1988).

A porcentagem de press animals na dieta foi provavelmente
subestimada pela dificuldade de observaqAo em conseqiiencia
do freqiiente uso de alturas maiores de dez metros. De uma
forma geral, o tipo de forrageamento de S. niger e parecido
corn aquele descrito para Saguinus imperator, Saguinus mystax e
Saguinus labiatus que utilizam em prevalancia os estratos baixos
e mrdios da floresta. Isto se diferencia daquele mostrado pelo
S. fuscicollis caracterizado por uma intense atividade
manipulat6ria e por um maior uso do sub-bosque e da parte
baixa da floresta (Garber, 1993b).

S. niger ocorre em virios tipos de habitats na Amaz6nia orien-
tal (Ferrari e Lopes, 1996); em Areas de floresta primiria como
de floresta secundiria, chegando nas Areas submontanas no sul
do Pari (Ferrari e Lopes Ferrari, 1990). 0 uso de habitats
secundarios parece preferencial em Paragominas (Mendes de
Oliveira, 1996), mas neste estudo nio teve diferenca significativa
entire o uso das ireas primArias (terra firme e igap6) e secundarias
ou de transigao. A distribuiqgo ou prefer&ncia para um particu-
lar tipo de presa animal nao parecem fatores determinantes na
escolha dos habitats, mas precisam de outros dados para uma
melhor interpretacio deste aspect. Um uso maior da floresta
de terra firme por S. niger em comparacao corn outros sftios da
Amaz6nia oriental, tern sido observado tambem por Bobadilla
e Ferrari (2000) que trabalharam numa outra area da ECFP A
grande biodiversidade em terms de composigco botanica
(Lisboa etal, 1997) observada em todos os habitats de Caxiuana
6 provavelmente responsivel por uma utilizacao menos seletiva
das diferentes ireas. No geral um uso de diferentes habitats e a
inclusio de uma grande diversidade de vegetaqio na area de
vida parece fundamental para S. niger assim como observado
em outras especies do genero Saguinus na Amaz6nia ocidental
(Terborgh, 1995; Peres, 1993a). 0 tamanho da Area de vida
do grupo em Caxiuana foi compiravel corn aquele observado
na especie S. midas (34-39 ha) por Kessel (1996) e foi
sensivelmente maior daquele observado por S. niger em
Paragominas (15,6 ha). A preferencia de S. niger para o estrato
mddio da floresta foi observada tambem por Bobadilla e Ferrari
(2000) enquanto Mendes de Oliveira (1996) relatou uma media
menor das alturas ocupadas.

A POSSIBLE RECORD OF CALLICEBUS IN ARGENTINA

Marcelo F Tejedor

The platyrrhine skull No 17.3 (Fig. 1) held by the Mammalogy
Section of the Museo Argentino de Ciencias Naturales
(MACN), Buenos Aires, is undoubtedly attributable to
Callicebus, and came from the Argentine province of Formosa.
In January 10, 1917, Mr. CAceres sold several mammalian speci-
mens from Formosa, including Panthera onca, Myrmecophaga,
Tamandua and the skull of Callicebus to the MACN. Although
this is the first record of Callicebus in Argentina, the remaining
genera certainly occur there.

The titi monkey, genus Callicebus, is one of the most diversi-
fled platyrrhines, widely distributed throughout the neotropical
forests especially in the Amazon and Orinoco basins, but also
in other regions such as the Atlantic and Parana forests in Bra-
zil, as well as in Bolivia and northwestern Paraguay (Hershkovitz,
1988, 1990). Following the latest taxonomic revision by
Hershkovitz (1990), the genus Callicebus includes 13 species
divided into four species-groups: modestus, donacophilus, moloch
andpersonatus. Among the donacophilus group, C donacophilus
occurs in the southernmost part of the geographic range for the
genus (excluding the isolatedpersonatus group in the south east

Ciencias Naturales, Buenos Aires.

of Brazil, at about the same latitude). In Paraguay, C.
donacophiluspallescens reaches the Pilcomayo river, a geographic
boundary between Paraguay and Argentina, but there are no
reports from the Argentine border.

A more precise location for the specimen from Formosa was
not provided by the collector Ciceres. Fieldwork in the area,
will be needed to confirm the continued occurrence or other-
wise of Callicebus in Argentina.

Acknowledgments: Drs. Marta Piantanida, Olga Vaccaro and
Gabriel Zunino (Secci6n Mastozoologia, Museo Argentino de
Ciencias Naturales. Buenos Aires) for providing access to the
specimens in their care.

TWINNING IN SEMI-FREE RANGING CAPUCHIN
MONKEYS (CEBUS APELLA)

Massimo Mannu
Eduardo B. Ottoni

The majority of primates give birth to a single offspring, except
for callitrichids (Fleagle, 1999) and some prosimians (Mittermeier
et al., 1994). Twinning is rare in other species. In captivity Stott
(1952) and D'amatto and Eisenstein (1972) reported twinning
in Cebus apella, Pissinatti et al. (1999) in


Figure 1. Cebus apella twins.


C. xanthosternos and Altmann etal. (1988) in Callimicogoeldii.
In the wild, Strier, (1990) mentions one case in Brachyteles
arachnoides, Crockett and Rudran, (1987) inAlouattaseniculus,
Chapman and Chapman, (1986) in Alouatta palliata, Bicca-
Marques and Calegaro-Marques, (1990) in Allouatta caraya,
Knogge and Heymann, (1995) in Callicebus cupreus cupreus,
and Aquino et al. (1990) in Aotus vociferans.

A semi-free ranging capuchin group lives in a semi-refor-
ested area of 180,000 m2in Tietd Ecological Park, Sao Paulo,
Brazil. They have been studied since January 1996 (Ottoni
and Mannu, in press) and now comprise a group of 23 indi-
viduals. In this long-term study, two out of 11 births were
sets of twins. The sets of twins were born to the same mother.
The first birth was reported by the veterinary Liliane
Milanello in September 1996. The surviving infant (Frank)
is now three and a half years old. The second twinning oc-
curred early in the morning of May 22, 1999, when the
observer arrived one of the newborns was still wet. As far as
we know this is the first report of capuchin monkey twin-
ning in semi-free ranging conditions. On the day of the birth
the smaller newborn was being carried by its mother in a
ventral position, whereas its bigger brother was being car-
ried in transverse-dorsal position. On the second day both
of them were being carried in transverse-dorsal position (Fig.
1). The smaller newborn was found dead on the morning of
May 24, 1999, while still being carried by its mother. The
other twin (Darwin) was still alive in July, 2000.

THREATENED PRIMATES OF MESOAMERICA AND
SOUTH AMERICA THE RED LIST 2000

Anthony B. Rylands
Ernesto Rodriguez-Luna

The 2000 IUCNRed List of Threatened Species was launched
on 28 September, 2000. It was compiled by Craig Hilton-
Taylor, and the assessment for primates was coordinated by
the IUCN/SSC Red List Authority for primates, Russell A.
Mittermeier, Chair of the Primate Specialist Group (PSG),
along with the Deputy Chairs for the PSG: William R.
Konstant and Anthony B. Rylands. The 2000 assessment
lists 39 species and 66 species and subspecies of Neotropical
primates as threatened, with a further 15 as "Data Deficient".
The taxonomy used for the assessment for the 2000 Red
List was that resulting from the Primate Specialist Group
workshop held in Orlando, Florida, in February 2000
(Rylands etaL, 2000). As with the 1996 RedList, the criteria
used to assess these species were those published by IUCN
in 1994 (IUCN, 1994). Future Red List assessments will
use a revised version of these criteria; "the 2000 criteria",
which have been approved by IUCN/SSC and will be pub-
lished in an upcoming issue of NeotropicalPrimates.


The numbers for Mesoamerica and South America are shown
in Tables 1 and 2, along with the distributions by country and
the criteria which determine their status. Mesoamerican coun-
tries have three species and 13 species and subspecies consid-
ered threatened, and there are 36 species and 56 species and
subspecies threatened in South America (Table 1). Nine spe-
cies are "Critically endangered", all from the Atlantic forest in
Brazil, except for the yellow-tailed woolly monkey, Oreonax
flavicauda, from the Peruvian Andes. Sixteen species and sub-
species are "Critically endangered"; three occur in Mesoamerica
and thirteen in South America (Table 1). Seventeen species
and subspecies are "Endangered", four occur in Mesoamerica
(three endemic) and 14 in South America.

Six Mesoamerican countries have threatened primates, the ma-
jority in Panama and Costa Rica, with eight and six species and
subspecies, respectively. Six South American countries have threat-
ened primates. The majority occurs in Brazil (36), followed by
Colombia with 17 species and subspecies and Peru with 10.

DISEASES OF CALLITRICHIDS AND CEBIDS

In 1999, Lilian R. M. de Sa defended her Master's thesis
entitled "Determination and characterization of disease of
callitrichids and cebids (multidisciplinary approach)", at the
Faculty of Veterinary Medicine and Zootechnology of the
University of Slo Paulo, Sao Paulo, Brazil. Her supervisor
was Dr. Jos6 Luiz Catio Dias, and it was financed by the
University and the state funding agency, the Fundacao de
Amparo a Pesquisas do Estado de Sao Paulo (FAPESP). The
following is an abstract of the thesis.

Little information is available in Brazil about the causes of
morbidity and mortality among Neotropical primates. The
aim of this study was to contribute to the knowledge con-
cerning the diseases of New World primates using clinical,
laboratory, microbiological, and parasitological data and pa-
thology examinations. Twenty-two callitrichids and 14 cebids
held in captivity or free-ranging were studied, and their dis-
eases and causes of death were determined and character-
ized. The animals were selected on the basis of the conserva-
tion of their carcasses sent to the Comparative Pathology
Laboratory, Faculty of Veterinary Medicine and Zootechny,
at the University of Sao Paulo, from January 1997 to Octo-
ber 1998. The final pathology diagnoses were made using
clinical history, laboratory data, bacterial growth from heart
blood and organs, and identification of protozoa. The data
revealed 14 cases of infection and parasitic death, six wast-
ing marmoset syndrome cases, two metabolic problems, three
digestive disturbances, three traumas, two reproductive dis-
eases, and one death each from electric shock, hematopoi-
etic problems, renal disease, respiratory disease, nervous sys-
tem disease and congenital anomalies. The bacterial agents
considered pathogenic were Corynebacterium spp., Strepto-
coccus spp., Klebsiella pneumoniae, Pasteurella multocida and


Leptospira interrogans. The deaths caused by protozoan infec-
tion were toxoplasmosis and infestation by enteric flagellates.
Micotic infections, candidiasis, zygomicosis and aspergillosis
were secondary infections that contributed to the poor health
of the animals. Campylobacter spp. was isolated from both as-
ymptomatic and clinically affected Neotropical primates. In
addition, other processes were diagnosed, such as hiperplasia
and neoplasia of the endocrine system, hepatic hemossiderosis,
ophthalmic lesions, atherosclerosis and metazoan parasites. The
results show the advantage of a complete pathology examina-
tion associated with bacterial culture and parasitic identifica-
tion, and so the need for implementation of general control
measures and for the prevention of zoonoses and infectious-
parasitic diseases in Neotropical primates.

COURSE ON THE "ECOLOGY OF NEW WORLD
PRIMATES" CURSO SOBRE "ECOLOGfA DE PRIMATES
NEOTROPICALES"

A course on the "Ecology of New World Primates" was held
from 02 to 06 October 2000 at the Universidad Nacional de
la Amazonfa Peruana (UNAP) in Iquitos (Peru). The course
was directed by Eckhard W. Heymann from the Deutsches
Primatenzentrum (DPZ, German Primate Center) and
Filomeno Encarnaci6n C. from the Universidad Nacional
Mayor de San Marcos (Lima, Peru) and hosted by the Facul-
ties of Forestry Engineering and Biological Sciences of UNAP
Sixteen students and staffmembers from UNAP participated
in this course which was supported by a grant from the
Margot Marsh Biodiversity Foundation. The course first
provided a general introduction to the diversity of New World
primates and their habitats. Then aspects of the ecology of




Neotropical Primates 8(3), September 2000


all genera of New World primates (e.g., feeding ecology) were
given, with emphasis on those genera occurring in Peru. The
major part of the course dealt with the ecological roles (e.g.,
seed dispersal, seed predation). The course ended with the
presentation of the problems of the conservation of New
World primates and their habitats. It is hoped that this theo-
retical course can be backed up by a practical field course in
the near future.

2000 IUCN RED LIST OF THREATENED SPECIES

The 2000 IUCNRed List of Threatened Species, 2000, 6lpp, +
CD-ROM, was launched on the 28h September 2000, in Lon-
don, Washington, Geneva, and Ottawa. It was compiled by
Craig Hilton-Taylor, with the assistance of Caroline Pollock,
Matthew Linkie, Alan Mauric, Janice Long, Mariano Gimenez-
Dixon, Simon Stuart, Alison Stattersfield, Martin Sneary, and
Georgina M. Mace, in association with experts in the IUCN/
SSC Species Survival Commission specialist groups and
BirdlLife International. Includes a foreword by David Brackett,
Chair of the IUCN Species Survival Commission, and an in-
troductory essay "A challenge to the global community" by
Russell A. Mittermeier, President of Conservation International
and Chairman of the Primate Specialist Group. Seven annexes:
1. Recent developments in the IUCN/SSC Red List
Programme; 2. Organization of information; 3. Information
sources and quality; 4. Habitat types authority file; 5. Threat


types authority file; 6. The 1994 IUCN Red List categories
and criteria; 7. Summary of the results of the review of IUCN
Red List categories and criteria 1996-2000 (Georgina M.
Mace). There are a number of innovations introduced to
enhance the effectiveness of the List as a conservation tool.
Improved species coverage: All bird species have been com-
pletely reassessed by BirdlLife International and its partners;
all primates have been reassessed following a consultative
review workshop on primate systematics (see Neotropical
Primates 8(2), pp.61-93); many other mammals, including
antelope, bats, cetaceans, otters, wild pigs, wild cattle and
wild goats, and some rodents were reassessed; improved cov-
erage of sharks, rays and saw-fish; all South-east Asian fresh-
water turtles were comprehensively assessed; a number of
new reptile and amphibian assessments from Brazil, the Phil-
ippines, Russian Federation and the Russian Republics were
carried out; the correction of some insect information and
the addition of a number of new European butterfly assess-
ments; correction of errors in the mollusc listings in the 1996
Red List, a thorough re-evaluation of all potentially extinct
species of mollusc and the inclusion of a number of new
assessments; all the tree assessments from The World List of
Threatened Trees (Oldfield et al., 1998) were incorporated
and updated where necessary; all conifers were comprehen-
sively reassessed; and new assessments for plants from
Cameroon, Galipagos, Mauritius and South Africa were in-
cluded, as were comprehensive assessments for the carnivo-
rous plant genera Nepenthes and Sarracenia, and for the first
time almost 100 assessments of mosses were included. Peer
review process carried out by the appointment of Red List
Authorities responsible for the evaluation of all assessments
on the Red List to help ensure the maintenance of standards
and the correct application of the criteria. Improved docu-
mentation: with the inclusion of a rationale for many listings
explaining how they were reached to improve accountabil-
ity; provision of information on range, current population
trends, main habitats, major threats and conservation mea-
sures taken; and improved documentation of extinct spe-
cies. Introduction of a petitions process whereby listings can
challenged. Increased accessibility via a new web site and a
CD-ROM. The web site provides a mechanism whereby users
can feed corrections and additional information back to the
Red List Programme. The web site is: redlist/2000/index.html>.

There are seven appendices. The second, "Hunting ofWild-
life in Tropical Forests: Implications for Biodiversity and
Forest Peoples", by Elizabeth L. Bennett and John G.
Robinson, 42pp., is based on the book recently published
by the same authors, Hunting for Sustainability in Tropical
Forests, Columbia University Press, New York, 2000. Be-
sides an executive summary, it has five chapters: 1. Intro-
duction; 2. The Sustainability of Hunting in Tropical For-
ests; 3. Factors Affecting the Sustainability of Hunting; 4.

for management and conservation. We hope to: 1) Help pro-
tected area managers to establish goals and determine priorities
for management and to design research programmes appropri-
ate to these objectives. 2) Outline simple, current, commonly-
used methods for collecting information, specifically on popu-
lation densities and behavioral ecology of larger animals, veg-
etation, physical features of the land, weather patterns, and the
numbers impacts, needs and expectations of people that use
and/or live near protected areas. 3) Present guidelines for ana-
lyzing field data realistically and with confidence; 4) Present
guidelines for interpreting and storing information with the
aim of making it useful and accessible to a variety of audiences."

Comparative Primate Socioecology, edited by Phyllis Lee, 1999,
438pp. Cambridge University Press, Cambridge, UK. ISBN
0 521 59336 0 (Hardback). Price: 45.00. Cambridge Stud-
ies in BiologicalandEvolutionaryAnthropology, 22. Compara-
tive studies have become both more frequent and more im-
portant as a means for understanding the biology, behaviour
and evolution of mammals. This book draws together a wide
range of experts from fields as diverse as reproductive biol-
ogy and foraging energetic to place recent field research into
a synthetic perspective. The chapters tackle controversial is-
sues in primate biology and behaviour, including the role of
brain expansion and infanticide in the evolution of primate
behavioral strategies. This book also presents an overview
of comparative methodologies as applied to recent primate
research. It is of particular relevance to primatologists and
behavioral ecologists as well those interested in the evolu-
tion of human social behaviour. Available from: UK and Ire-

compatible text-editors (MS-Word, WordPerfect, Excel, and Ac-
cess), and/or e-mailed to . (English,
Portuguese) or (Spanish) Hard
copies should be supplied for all figures (illustrations and maps)
and tables. The full name and address for each author should be
included. Please avoid abbreviations and acronyms without the
name in full. Authors whose first language is not English, please
have texts carefully reviewed by a native English speaker.

Articles. Each issue ofNeotropicalPrimates will include up to three
full articles, limited to the following topics: Taxonomy, Systemat-
ics, Genetics (when relevant for systematics), Biogeography, Ecol-
ogy and Conservation. Texts for full articles should not exceed
about 20 pages in length (1.5 spaced, and including the refer-
ences). Please include an abstract in English, and (optional) one in
Portuguese or Spanish. Tables and illustrations should be limited
to six, excepting only the cases where they are fundamental for the
text (as in species descriptions, for example). Full articles will be
sent out for peer-review.

Short articles. These are reviewed only by the editors. A broader
range of topics are encouraged, including such as behavioral re-
search, in the interests of informing on general research activities
which contribute to our understanding of platyrrhines. We en-
courage reports on projects and conservation and research pro-
grams (who, what, where, when, why etc.) and most particularly
information on geographical distributions, locality records, and
protected areas and the primates which occur in them. Texts should
not exceed 10 pages in length (1.5 spaced, including the refer-
ences).


Figures and maps. Articles can include small black-and-white pho-
tographs, high quality figures, and high quality maps and tables.
Please keep these to a minimum. We stress the importance of pro-
viding maps which are publishable.

News items. Please send us information on projects, field sites,
courses, recent publications, awards, events, activities of Primate
Societies, etc.
