Invasive Cuban Treefrogs Establish First Known Population in Louisiana
A population of the invasive treefrogs has been discovered in New Orleans, more than 430 miles from the nearest known population in Florida.Read more
New Genetic Test Detects Manatees' Recent Presence in Waterways
WARC scientists have developed the first lab test that can pick up traces of manatees' genetic material in fresh or saltwaterLearn more
WARC conducts relevant and objective research, develops new approaches and technologies, and disseminates scientific information needed to understand, manage, conserve, and restore wetlands and other aquatic and coastal ecosystems and their associated plant and animal communities throughout the nation and the world.

As wildlife diseases increase globally, an understanding of host-pathogen relationships can elucidate avenues for management and improve conservation efficacy. Amphibians are among the most threatened groups of wildlife, and disease is a major factor in global amphibian declines.
Amphibian species and community richness has been declining in North America and climate change may play a role in these declines. Global climate change has led to a range shift of many wildlife species and thus understanding how these changes in species distribution can be used to predict amphibian community responses that may improve conservation efforts.
Expectations of Maurepas Swamp response to a river reintroduction, Louisiana
Mississippi River reintroductions (freshwater diversions) into wetlands previously disconnected from the river have been implemented in southeastern Louisiana as a means to rehabilitate degraded and submerging wetlands. To date, all active Mississippi River reintroductions have targeted marsh habitat. However, a 57 cubic meter per second (2,000...Krauss, Ken W.; Shaffer, Gary P.; Keim, Richard F.; Chambers, Jim L.; Wood, William B.; Hartley, Stephen B.
Stable isotope analysis enhances our understanding of diamondback terrapin Malaclemys terrapin foraging ecology
Dietary studies on generalist predators may provide valuable information on spatial or temporal changes in the structure of ecological communities. We initiated this study to provide baseline data and determine the utility of stable isotope analysis (SIA) to evaluate the foraging strategies of an opportunistic reptilian predator, the diamondback...Denton, Mathew J.; Demopoulos, Amanda W.J.; Baldwin, John D.; Smith, Brian; Hart, Kristen M.
Integrating encounter theory with decision analysis to evaluate collision risk and determine optimal protection zones for wildlife
1.Better understanding human‐wildlife interactions and their links with management can help improve the design of wildlife protection zones. One example is the problem of wildlife collisions with vehicles or human‐built structures (e.g. power lines, wind farms). In fact, collisions between marine wildlife and watercraft are among the major threats...Udell, B.J.; Martin, Julien; Fletcher, R.J.; Bonneau, Mathieu; Edwards, Hank; Gowan, T.; Hardy, Stacie K.; Gurarie, E.; Calleson, C.S.; Deutsch, C.J.
