Amphibian Research & Monitoring Initiative (ARMI)
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.

Using Occupancy Analysis to Understand Ecological and Environmental Stressors that Affect the Range and Abundance of Gulf Coast Waterdogs (Necturus beyeri) in Louisiana Bayous
Sampling for Gulf Coast waterdogs is providing essential information to better understand the factors that impact the species' occupancy across Louisiana.
Monitoring and Removal of Invasive Cuban Treefrogs (Osteopilus septentrionalis) on the Gulf Coast
WARC researchers are performing visual encounter surveys and passively capturing Cuban treefrogs to remove as many of the invasive anurans as possible.
Effects of Saltwater Intrusion on Anuran Occupancy in Big Thicket National Preserve, Texas
WARC researchers sampled anuran populations at sites within Big Thicket National Preserve to explore saltwater intrusion on these populations.
Acoustic Monitoring for Two Rare Frog Species in Northwest Louisiana
WARC researchers are using automated recording units to monitor southern crawfish frogs and Strecker's chorus frogs in Louisiana.
Amphibian Research and Occupancy Modeling in the South-Central Region of the Amphibian Research and Monitoring Initiative (ARMI)
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.
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.
Capture-Mark-Recapture of Treefrogs at Bayou Teche National Wildlife Refuge
WARC researchers are gathering amphibian data to better understand the impact of natural disasters on treefrog populations and examine post-event processes.
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.
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.
