Past Team Members

	Evan Grant Evan H. Campbell Grant, USGS Patuxent Wildlife Research Center, Wildlife Biologist. Evan began working with the NE ARMI research team in March of 2003, just in time for the breeding migration of the spotted salamanders and the beginning of the field season.  He received his PhD in Marine, Estuarine and Environmental Sciences from the University of Maryland, College Park.  His research focuses on the movement ecology of stream amphibians, but he has other interests in ecology at larger spatial scales. Contact Evan: 301-497-5842 email: ehgrant@usgs.gov
	Adrianne Brand Adrianne Brand, USGS Patuxent Wildlife Research Center, Biological Science Technician. Adrianne joined the NE ARMI research team in May of 2009.  Adrianne received her MS in Biology from Towson University in 2008, where she studied amphibian use of stormwater ponds with Dr. Joel W. Snodgrass.  Adrianne’s responsibilities include data collection during the field season, assisting with the management of the NE ARMI database, and preparing research reports. Contact Adrianne: 301-497-5637 email: abrand@usgs.gov
	Eric Dallalio Eric Dallalio, USGS Patuxent Wildlife Research Center, Biological Science Technician. Eric joined the NE ARMI research team in January of 2010.  Eric concurrently works toward his MS in Biology from Towson University, where he studies the response of Plethodontid salamanders to competition under climate change with Dr. Joel W. Snodgrass.  Eric’s responsibilities include data collection during the field season, assisting with the management of the NE ARMI database, preparing research reports, and managing salamander experiments. Contact Eric: 301-497-5811 email: edallalio@usgs.gov
	Andrew Dietrich Andrew Dietrich, USGS Patuxent Wildlife Research Center, Biological Science Technician. Andrew (re)joined the NE ARMI team in September of 2012. Andrew received his MS in Environmental Science and Management from Portland State University in 2012. His Master’s thesis investigated stream-associated amphibians in the urbanized riparian systems of the Portland, Oregon metropolitan region under the guidance of Dr. Alan Yeakley. Andrew’s responsibilities include data collection during the field season, assisting with the management of the NE ARMI database and preparing research reports. Contact Andrew: 301-497-5842 email: adietrich@usgs.gov
	Will Fields Will Fields, USGS Patuxent Wildlife Research Center, Postdoctoral Research Associate. Will joined the NE ARMI Research Team in 2012, and he is currently involved in research examining the effects of stream network structure on salamander populations in the mountains of Virginia. He completed his PhD in Zoology at North Carolina State University, where his dissertation research focused on evaluating the effects of climate change on salamander demography, comparing the relative contributions of amphibian breeding and dispersal habitat to landscape connectivity, testing habitat models for a rare salamander across its range, and testing assumptions about landscape connectivity with experiments on amphibian movement behavior. Contact Will: 301-497-5625 email: wfields@usgs.gov
	Viviana Ruiz My research interests span across the fields of population ecology and conservation biology. I got my BS in Tropical Biology in 2002, and my PhD in Ecology and Evolutionary Biology in 2009. My dissertation work was focused on looking at the responses of tropical bird populations to habitat fragmentation, by applying both capture-mark-recapture and occupancy models. For my postdoctoral research, I have been working on designing sampling guidelines to help increase our knowledge on the demography of tropical birds. In addition, I worked on estimating overwintering dynamics of Neotropical migratory birds in Central America. I recently started a new postdoctoral position with Dr. Evan Grant and Dr. Mevin Hooten (USGS Coop Unit, Colorado State University). Our project focuses on developing calling anuran spatial occupancy models for the Northeastern US, to interpret the role of National Wildlife Refuges in amphibian conservation.

	Amber Wiewel Amber Wiewel, USGS Patuxent Wildlife Research Center, Database Technician. Amber began working with the NE ARMI research team in May of 2011. She received her MS in Ecology and Evolutionary Biology from Iowa State University in 2011. Amber’s responsibilities include data collection during the field season, data management, and contributing to reports. Contact Amber: email: awiewel@usgs.gov
	Elise Zipkin Elise Zipkin, USGS Patuxent Wildlife Research Center, Postdoctoral Research Associate. Elise started working with the NE ARMI research team in the fall of 2010, and is currently working on understanding the factors that affect the success or failure of wetland breeding amphibian populations within National Parks in the northeast region. She received her PhD in Biology from the University of Maryland, College Park in 2012. Elise's broader research focuses on the development of statistical models to improve estimation of wildlife distributions and abundances. Contact Elise: email: ezipkin@usgs.gov
