Summary and synthesis of 15 years of the Amphibian Vital Sign monitoring in the National Capital Region Inventory and Monitoring Network Summary and synthesis of 15 years of the Amphibian Vital Sign monitoring in the National Capital Region Inventory and Monitoring Network
The amphibian monitoring program, designed and conducted by the U.S. Geological Survey’s Amphibian Research and Monitoring Initiative program, is designed to estimate the status and trends of amphibian populations to assist management decisions in individual parks and across the National Capital Region Network. Detection/non-detection data for stream and wetland habitats has been...

Site- and individual-level contaminations affect infection prevalence of an emerging infectious disease of amphibians Site- and individual-level contaminations affect infection prevalence of an emerging infectious disease of amphibians
Emerging infectious disease outbreaks are one of multiple stressors responsible for amphibian declines globally. In the northeastern United States, ranaviral diseases are prevalent in amphibians and other ectothermic species, but there is still uncertainty as to whether their presence is leading to population level effects. Further, there is also uncertainty surrounding the potential...

Geographic variation and thermal plasticity shape salamander metabolic rates under current and future climates Geographic variation and thermal plasticity shape salamander metabolic rates under current and future climates
Predicted changes in global temperature are expected to increase extinction risk for ectotherms, primarily through increased metabolic rates. Higher metabolic rates generate increased maintenance energy costs which are a major component of energy budgets. Organisms often employ plastic or evolutionary (e.g., local adaptation) mechanisms to optimize metabolic rate with respect to their...

Evaluating the effect of expert elicitation techniques on population status assessment in the face of large uncertainty Evaluating the effect of expert elicitation techniques on population status assessment in the face of large uncertainty
Population projection models are important tools for conservation and management. They are often used for population status assessments, for threat analyses, and to predict the consequences of conservation actions. Although conservation decisions should be informed by science, critical decisions are often made with very little information to support decision-making. Conversely...

Identifying climate-resistant vernal pools: Hydrologic refugia for amphibian reproduction under droughts and climate change Identifying climate-resistant vernal pools: Hydrologic refugia for amphibian reproduction under droughts and climate change
Vernal pools of the northeastern United States provide important breeding habitat for amphibians but may be sensitive to droughts and climate change. These seasonal wetlands typically fill by early spring and dry by mid-to-late summer. Because climate change may produce earlier and stronger growing-season evapotranspiration combined with increasing droughts and shifts in precipitation...

Experimental evaluation of spatial capture–recapture study design Experimental evaluation of spatial capture–recapture study design
A principal challenge impeding strong inference in analyses of wild populations is the lack of robust and long-term data sets. Recent advancements in analytical tools used in wildlife science may increase our ability to integrate smaller data sets and enhance the statistical power of population estimates. One such advancement, the development of spatial capture–recapture (SCR) methods...
