Abstract:
Globally, invasive species are quickly coming to the forefront of ecological studies and conservation. The Burmese python (Python bivittatus) is a well-known and established invasive species in southern Florida that is affecting biodiversity. Burmese pythons in Everglades National Park, an area with a well-established population, are linked to the severe mammal declines seen in the region. Due to these changes in available prey species, we expected to find temporal and spatial shifts in prey species composition in the python diet. Data on Burmese python diet have been collected through necropsies of individuals collected throughout southern Florida, from the southern end of Everglades National Park, north to southwest Naples. Prey species from the digestive tract contents of 715 individual pythons collected from 2009 to the present have been identified. We used these data in comparative statistical analyses to evaluate temporal and spatial shifts in prey species composition. Prey species range from Hispid Cotton Rats (Sigmodon hispidus) and Great Egrets (Ardea alba) to Alligators (Alligator Mississippians) and Bobcats (Lynx rufus). A better understanding on how invasive pythons use prey biodiversity as they expand their range and establish new populations is essential to long-term management of threatened and endangered species within this landscape.
