Biology, Impacts and Control of Invasive Reptiles in the Everglades

Active
By Fort Collins Science Center February 11, 2023

Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.

FORT's invasive reptile research in Florida focuses on understanding impacts and developing adaptive control opportunities for Burmese pythons and other recent invaders such as black and white tegus. Branch scientists combine extensive herpetological expertise with cutting-edge quantitative skills to inform and estimate detection probability, population size, and eradication prospects for a range of invasive reptiles. Projects and collaborators span across the United States mainland to Pacific islands.

Below are other science projects associated with this project.

Ecology and Control of Invasive Reptiles in Florida

This project involves development of tools for the detection and control of invasive reptiles in Florida, with an emphasis on pythons and tegu lizards. The goals are to reduce the risk of reptile invasions, investigate early detection methods, maintain rapid response capacity, and understand invasive reptile population biology and ecology to inform management options.

Giant Constrictor Snakes in Florida: A Sizeable Research Challenge

Since the mid-1990s, several species of non-native, giant constrictor snakes, such as Burmese pythons and boa constrictors, have surfaced in localities throughout southern Florida. Several are known or suspected to be breeding and appear to be spreading northward. Increasingly, media and other reports of sightings or encounters with these animals have emphasized the dangers they could impose on...

Flooding-induced failure of an invasive Burmese Python nest in southern Florida

It is important to understand the factors affecting the reproductive success of an invasive species to estimate population size and develop management plans.

Capsaicin-treated bait is ineffective in deterring non-target mammals from trap disturbance during invasive lizard control

Excluding non-target species from invasive species control efforts can be challenging due to non-target attraction to trap structure, baits, and lures. Various methods have been used to deter non-target species from entering or disturbing traps including altered features (e.g., mesh size, trip mechanism, or entrances), staking traps, and chemical deterrents.

Divergent Serpentoviruses in free-ranging invasive pythons and native colubrids in southern Florida, United States

Burmese python (Python bivittatus) is an invasive snake that has significantly affected ecosystems in southern Florida, United States. Aside from direct predation and competition, invasive species can also introduce nonnative pathogens that can adversely affect native species. The subfamily Serpentovirinae (order Nidovirales) is composed of positive-sense RNA viruses primarily found in reptiles. S
