Dan Calhoun is Assistant Director of Studies for the South Atlantic Water Science Center
My unofficial career with the USGS began in 1995 when I was “volunteered” to help USGS Hydrologic Technicians dig orifice lines and haul materials for new gage installations along Ichawaynochaway Creek in Southwest Georgia. I was working as a Hydrologic Technician for the Jones Ecological Research Center and had no idea what a couple days of Georgia Coastal Plain sweat would later bring. It was through this encounter that I was given an invitation to apply for an open student position (STEP in those days) with the USGS after starting graduate studies in Water Resources at the University of Georgia in 1998. Upon completion of my degree, I converted to a Hydrologist position working with the Appalachicola-Chattahoochee-Flint Study Unit (ACFB) of the National Water Quality Assessment Program. Twenty plus years of employment have involved participation in and direction of multiple national and regional watershed and groundwater projects, amphibian research in the Southeast, liaison duties with the NPS during the Deep Water Horizon oil spill, many Regional Stream Quality Assessment tours of duty across the country, a wide assortment of scientific publications, and many other varied wonderful ways to make a living working for the USGS and DOI. I now serve as an Assistant Director for Hydrologic Studies in Georgia for the South Atlantic Water Science Center and wouldn’t trade a minute of the time spent with the people with whom I have had the privilege of working.

Amphibian Research and Monitoring Initiative (ARMI) - Characterizing Wetland Habitat and Hydrology
The U.S. Geological Survey's (USGS) Amphibian Research and Monitoring Initiative (ARMI) began in 2000 with the goal of determining the status and trends of amphibian populations throughout the U.S. The program was designed to provide information useful in determining causes of declines or other changes in population distributions.

Elucidating mechanisms underlying amphibian declines in North America using hierarchical spatial models
Amphibian populations are declining globally at unprecedented rates but statistically rigorous identification of mechanisms is lacking. Identification of reasons underlying large-scale declines is imperative to plan and implement effective conservation efforts. Most research on amphibian population decline has focused on local populations and local factors. However, the ubiquity of declines across
