Northeast Amphibian Research and Monitoring Initiative
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.

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

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.

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.

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.

Viviana RuizMy 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, 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.
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.
