Wetland and Aquatic Research Center and Fort Collins Science Center are coordinating a long-term, landscape-scale Burmese python research strategy for South Florida.
Understanding Greater Everglades Mammal Communities within and adjacent to the Arthur R. Marshall Loxahatchee National Wildlife Refuge
WARC Researchers are using a variety of methods to assess mammal communities across the Greater Everglades.
Prevalence Rates of Snake Fungal Disease and Its Population-level Impacts in a Snake Assemblage in Southwest Louisiana
WARC researchers used visual encounter surveys to determine prevalence rates of snake fungal disease in south-central Louisiana.
Alligator Snapping Turtle (Macrochelys temminckii) Research in Louisiana in Support of the Species Status Assessment and Listing Decision by the U.S. Fish and Wildlife Service
WARC researchers are investigating individual movement, growth, and population dynamics of alligator snapping turtles in a southwest Louisiana creek.
Fine-Scale Dive Profiles and Activity Patterns of Sea Turtles in the Gulf of Mexico
Researchers are developing acceleration data logger pop-off packages that can be affixed to sea turtles to collect behavioral patterns of diving, surfacing, and general activity levels.
Applications of Advanced Tracking and Modeling Tools with Burmese Pythons across South Florida's Landscape
Researchers will determine movement rates and habitat-use patterns of pythons across the South Florida landscape by conducting a telemetry study tracking pythons simultaneously in several locations
Habitat Selection of the Burmese Python in the Florida Everglades
Researchers plotted locations of radio-tagged pythons to create a habitat suitability model.
Hotspot and Risk Analysis for Sea Turtles in the Florida Keys National Marine Sanctuary
Researchers will collect location data that will be used to identify areas of high-use for resident sea turtles in the Florida Keys National Marine Sanctuary.
Informing Future Condition Scenario Planning for Habitat Specialists of the Imperiled Pine Rockland Ecosystem of South Florida
South Florida's pine rockland ecosystem represents less than 3% of its original extent. This project will evaluate habitat conditions for two pine rockland snake species to develop future habitat condition scenarios for Species Status Assessments.
Survey and Assessment of Live Food Markets as an Invasion Pathway
Live food markets may be a source of the increasing number of non-native wild invertebrate and fish species, like Asian swamp eels and snakeheads. USGS is surveying such markets around the United States to identify and document species that might be of concern if released live into the wild to assess if the live food market is a possible invasion pathway.
A Structured Decision-Making Framework for Controlling, Monitoring, and Containment of Invasive Species through Trapping: An Application to the Argentine Black and White Tegu
USGS is applying decision analysis to identify cost-effective methods for controlling invasive species like the Argentine black and white tegu.
