Biology, Impacts and Control of Invasive Reptiles in the Everglades

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.

Species Distribution Modeling

A requirement for managing a species, be it a common native species, a species of conservation concern, or an invasive species, is having some information on its distribution and potential drivers of distribution. Branch scientists have been tackling the question of where these types of species are and where they might be in the future.

Environmental DNA (eDNA) Sampling Improves Occurrence and Detection Estimates of Invasive Burmese Pythons and Other Constrictor Snakes in Florida

Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

Ecology and Control of Invasive Reptiles in Florida

This project involves ongoing development of tools for the detection and capture of invasive reptiles in Florida, with an emphasis on Burmese pythons (Python bivittatus) and Black and white tegu lizards (Salvator merianae). The goals are to reduce the risk of reptile invasions in high-value resources such as Everglades National Park and the Florida Keys, to access early detection methods of new...

Control and Landscape-Scale Suppression of the Invasive Brown Treesnake

The Brown Treesnake is a highly destructive reptile species that has extirpated many native species of birds, bats, and lizards from the U.S. Territory of Guam. For more than two decades branch scientists with the Invasive Reptile Project have developed, validated, and tested the feasibility of Brown Treesnake control and suppression at various spatial scales.

Cruising to Improve the Detection of Burmese Pythons in Everglades National Park

It is not uncommon to see researchers cruising around Everglades National Park (ENP) on what has been a routine basis for the past ten months. Every evening, interns pack into a Chevy Volt for their shift assisting the U.S. Geological Survey in conducting Burmese Python (Python molurus bivittatus) nighttime surveillance through observational surveys. This effort to detect non-native snakes, namely...
