Amphibian Research & Monitoring Initiative (ARMI)

In response to growing concerns over declines in amphibian populations around the world, the Department of Interior was directed to initiate a national program for amphibian monitoring, research, and conservation. USGS scientists have long been at the forefront of studying amphibian biology and ecology, their environmental needs, and potential causes of population decline. The National Amphibian Research and Monitoring Initiative (ARMI) aims to provide information to natural resource managers on the status and trends of amphibians; relate status and trends to management options at the scale of management units; identify causes of decline; and provide essential scientific information to support effective management actions to stop or reverse declines. WARC scientists coordinate and conduct ARMI activities in the South Central and Southeast ARMI regions.

Monitoring of Amphibians at St. Marks National Wildlife Refuge in Northwest Florida

Freshwater wetlands provide critical habitat for a diverse array of organisms, including many amphibians. Yet, under the threat of climate change, these habitats are among the most imperiled ecosystems on Earth.

Amphibian Occupancy Modeling in the South-Central Amphibian Research and Monitoring Initiative (ARMI) Region

In response to growing public concerns about this loss of biodiversity, the U.S. Congress funded the Amphibian Research and Monitoring Initiative (ARMI), a national program coordinated by the U.S. Geological Survey.

Population Demography and Food Web Analysis of Large Aquatic Salamanders (Siren and Amphiuma) in North Florida

Understanding amphibian's life-histories can help predict how they may persist in aquatic habitats in the face of droughts and other climate change-associated events.

Evaluating the Prevalence of the Amphibian Chytrid Fungus, Batrachochytrium dendrobatidis, in the Southeastern U.S.: Any Evidence of Disease-Related Population Declines?

Pathogens and infectious disease play a role in some recent species extinctions and are likely to impact biodiversity in the future. Environmental DNA - eDNA - is coupled with traditional amphibian sampling methods to determine the distribution and prevalence of the amphibian chytrid fungus, also known as Bd, in the southeastern US.

Use of Amphibian Communities as Indicators of Restoration Success in the Greater Everglades

Habitat alteration and climate, when combined, are serious threats to amphibians and other wildlife. Habitat suitability models are being used to predict the responses of an amphibian community to hydrological and habitat restoration in the Greater Everglades Ecosystem.
