Species Biology

Research into life history, successful conservation, and recovery of threatened and endangered species listed under the Endangered Species Act; trust species that are protected by law; sensitive species that are declining, rare, or uncommon and are identified as candidates for future listing consideration; and species of management concern that warrant management or conservation attention as identified by a natural resource management agency. This category includes a variety of species, including those that are considered at-risk, have economic or intrinsic value, or are overly abundant and therefore leading to management conflicts; biological systematics to understand the evolutionary interrelationships of living things, trying to interpret the way in which life has diversified and changed over time; and decision science, a collaborative approach involving mathematical formulae, business tactics, technological applications, and behavioral sciences to help management make data driven decisions.

Interaction of Environmental Stressors and Batrachochytrium dendrobatidis (Bd) Pathogen Loads on Survival of Green Frogs (Lithobates clamitans)

The U.S. Geological Survey Amphibian Research Monitoring Initiative (ARMI) is using a combination of swabbing, non-lethal tissue sampling, soil and water sampling, and collection of a variety of other environmental variables to determine the relationships between the prevalence and pathogen load of Bd infection and environmental stressors on green treefrog survival.

Diet and Reproductive Phenology in a Recently Established Population of Invasive Cuban Treefrogs (Osteopilus septentrionalis)

WARC researchers are exploring relationships between body size, time of year, sex, and reproductive development to better understand the reproductive phenology of the New Orleans population of Cuban treefrogs compared to Florida populations.

Submerged Aquatic Vegetation Preferences of Fishes in Lake Apopka, Florida

To achieve the adaptive restoration objective of maximizing fish habitat, researchers will sample fish communities in Florida's Lake Apopka to compare between natural submerged aquatic vegetation (SAV), restored SAV, and bare bottom habitat. To undertand SAV preference of juvenile largemouth bass, researchers will conduct controlled experiments. These experiments will help managers select...

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.
