Evan Grant

Evan H. Campbell Grant, USGS Patuxent Wildlife Research Center, Research 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

Adrianne Brand

Adrianne Brand, USGS Patuxent Wildlife Research Center, Wildlife Biologist. Adrianne joined the NE ARMI research team in May of 2009. She received her MS in Biology at Towson University in 2008 after completing research on stormwater ponds as breeding habitats for suburban amphibian populations. Adrianne’s responsibilities include data collection during the field season, database management, and writing research reports and publications.

Eric Dallalio

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.

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.

Will Fields

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.

Viviana Ruiz

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.

Rachel Katz

Rachel Katz is Postdoctoral Research Associate with the USGS Massachusetts Cooperative Fish and Wildlife Research Unit at the University of Massachusetts-Amherst. Rachel is currently working with researchers and natural resource managers to develop a structured-decision making framework for the conservation of headwater stream species (e.g., native trout and stream salamanders) threatened by climate and land use change within the northeastern US. This project serves as a model for effective landscape-scale collaborative conservation and aims to evaluate adaptive capacity of institutions to manage threats associated with climate change. She received her PhD in Ecology from the Odum School of Ecology at the University of Georgia in 2014. Rachel's broader research interests include developing flow-ecology relationships to better understand population dynamics and persistence of aquatic species.

Sean Sterrett

Sean Sterrett

Sean Sterrett, USGS Patuxent Research Center, Postdoctoral Research Associate. Sean joined the NE ARMI research team in 2014 and will be focusing on a collaborative project aimed at using regional citizen science data to answer questions related to climate change effects on red back salamander ecology at multiple scales. Sean has a general background in amphibian and reptile ecology and completed his M.S. and Ph.D. in Wildlife Ecology and Management from the University of Georgia studying influences of riparian land use on river turtle communities and nutrient dynamics of freshwater turtles. Sean’s general research interests include the effects of human alterations on amphibians and reptiles, vertebrate influences on ecosystems and natural history.
