Chauncey Anderson is a hydrologist for the U. S. Geological Survey's Oregon Water Science Center. Chauncey has worked for the USGS since 1991, focusing on water quality and ecosystem-oriented studies. He joined the ARMI program in 2000 as Hydrologic Coordinator for ARMI's Pacific Northwest Region. As such, Chauncey works to provide water quality and other hydrologic support to the ARMI program in the Pacific Northwest and elsewhere. Since 2004, he has worked on issues associate with chytrid fungus (Batrachochytrium dendrobatidis, or Bd); specifically, its occurrence in the environment, including detection in water and efforts to better understand its life history cycle outside of amphibian hosts. Chauncey is supporting a Ph. D. candidate from Portland State University, Tara Chestnut, who is working to better quantify sampling and environmental variability for Bd, and apply this work to questions of disease movement in northern latitudes as a result of climate change. Chauncey has also extensively studied nutrient and algal interactions, the role of land management in receiving water quality, contaminants in water, sediment, and biota, and has recently been involved in studies of water quality associated with dam removal as an ecosystem restoration strategy.

Gary Fellers coordinates ARMI activities in northern and central California from the Point Reyes Field Station located at Point Reyes National Seashore. Research and monitoring is being conducted throughout the region, with an emphasis on Point Reyes and Yosemite NP, where research is done in cooperation with the National Park Service. Research is examining the causes of amphibian declines, with a special emphasis on the role of pesticides and chytrid fungus. Intensive, site-specific studies with California red-legged frogs and Sierra Nevada yellow-legged frogs are designed to assess population size and trends, as well as frog movements, growth, and longevity. The research program has an international flavor with active cooperators in both Taiwan and China. This work is led by Gary Fellers (Ph.D. University of Maryland) who has been conducting research on declining amphibians since 1991, and was the catalyst for the design and implementation of the ARMI program.
Amphibian monitoring and research, through the ARMI program, is an integral part of the USGS San Diego Field Station’s mission. Principal Investigator, Robert Fisher’s (PhD UC Davis) research focuses on conducting inventory, monitoring, population estimates, restoration, and species recovery. Our geographic area of research extends from the California–Mexico border north through Ventura and San Bernardino Counties to Inyo County at the north end. Our studies occur in a diverse variety of habitats including coastal salt marshes, coastal sage scrub, inland chaparral, oak and riparian woodlands, high elevation coniferous forests, and deserts. We partner with many public agencies, non-governmental organizations, and private entities. The goal is to provide data that our partners can use to guide management activities. Several on-going studies involve sensitive, threatened, and endangered amphibian species including the federally listed arroyo toad (Anaxyrus californicus), mountain yellow-legged frog (Rana muscosa), and the California red-legged frog (Rana draytonii).
Amphibian research and monitoring has been an important part of the mission of the Sonoran Desert Research Station since 1993. Principal Investigator Cecil Schwalbe's (PhD University of Arizona) research includes monitoring, population estimates, ecology and control of invasive species, disease, and conservation of vulnerable species, focusing primarily in Arizona, but extending to adjacent states. Research funded and facilitated by ARMI has ushered in a ground swell of cooperative research and management efforts to conserve native amphibians in Arizona, focusing on control and elimination of invasive American bullfrogs on a landscape scale through cooperation with federal and state agencies, universities, non-governmental organizations, and privateranchers. Ranchers throughout the range of the threatened Chiricahua leopard frog have sought technical advice on similar efforts.

ARMI staff and key collaborators in the Midwest region include Walt Sadinski (Upper Midwest Environmental Sciences Center [UMESC]; research ecologist and principal investigator; Ph.D., Penn State University), Mark Roth (UMESC; biologist; MS, University of Arkansas, Monticello), Perry Jones (Minnesota Water Science Center; hydrologist; MS University of Minnesota), and Alisa Gallant (Earth Resources Observation and Science Center, ecogeographer; Ph.D., Colorado State University). We are assessing the statuses of regional amphibian populations relative to drivers of global change, primarily land use, climate change, and emergent disease, on Department of Interior and other lands in Iowa, Illinois, Wisconsin, and Minnesota. We also are leveraging these efforts with those of a wide range of partners in several additional states (including Alaska) and Canadian provinces to collect and analyze data across a network of research sites. By using standardized protocols with our partners, results from our work are intended to provide information necessary to assess and help conserve amphibian populations at local and broader scales along North American environmental gradients.
Hardin Waddle (PhD University of Florida) coordinates ARMI activities in the south-central ARMI region from the National Wetlands Research Center (NWRC) in Lafayette, LA. The mission of the NWRC is to develop and disseminate scientific information needed for understanding the ecology and values of our Nation's wetlands and for managing and restoring wetland habitats and associated plant and animal communities. Dr. Waddle’s particular interests include population ecology and conservation of amphibians and reptiles. The focus of south-central ARMI research involves using occupancy analysis to detect trends in anuran populations. Since 2002, south-central ARMI has been monitoring anuran populations in the Atchafalaya Basin of south-central Louisiana, with similar monitoring now being conducted at Coldwater River National Wildlife Refuge in north Mississippi and Big Thicket National Preserve in east Texas. In addition, a population ecology study commenced in Fall 2010 on ambystomatid salamander populations in Kisatchie National Forest in north central Louisiana. Data garnered from these studies will assist land managers to make more informed decisions regarding resource management.
Dr. Evan H. Campbell Grant (PhD University of Maryland) coordinates ARMI activities in the Northeast by conducting and developing amphibian research and monitoring projects. Information from surveys in the Northeast are used to determine the proportion of surveyed areas that are occupied by various species of amphibians, and to estimate amphibian survival, dispersal, and population sizes and trends over space and time. This information is used to inform management of National Park and Wildlife Refuge Resources in the northeast.
Biology-based ARMI activities in the southeast are coordinated by Dr. Susan Walls at the Southeast Ecological Science Center (SESC). Susan received a PhD from the University of Louisiana (Lafayette) and has conducted ecological studies of amphibians for nearly 30 years.
