Samantha Dwinnell Website:

Like most wildlife researchers, Samantha Dwinnell is an adventurer at heart. After receiving a B.S. in Biology and a B.A. in Environmental Studies from the University of Minnesota – Duluth in 2007, Sam embarked on the expected departure from the flat prairies of the Midwest to the granite slopes of the Rocky Mountains. Her broad interests in wildlife ecology and desire for exploring different systems carried her through seven years of working on a variety of wildlife research projects throughout the Intermountain West. Among her experiences, the most notable in molding her career were those affiliated with the Wyoming Cooperative Fish and Wildlife Research Unit. She began her career with the WY Coop in 2008 as a field technician assisting with research investigating the effects of energy development on songbird communities in western Wyoming. She then segued into another position within the WY Coop where she assisted with research studying the influence of backcountry recreation on habitat selection of bighorn sheep in Grand Teton National Park. Projects like these allowed Sam to develop her research interests in applied ecology while simultaneously satiating her need for adventure.

Greg Nickerson

Gregory Nickerson Website:

Greg is a writer and flimmaker for the Wyoming Migration Initiative. He works to inform and educate the public about migration research, with a special focus on researching the human stories surrounding wildlife migration. Originally from Big Horn, Wyoming, he's a lifelong hunter of migratory elk in the Meeteetse and Wapiti area, and has worked as a mule deer and elk guide for the Darwin Ranch in the Gros Ventre Mountains. His first documentary for Wyoming PBS chronicled the art of Thomas Moran and the photography of William Henry Jackson on the 1871 Hayden expedition to Yellowstone, which led Congress to set aside the area as America's first national park. In 2013, he won a Mid-Atlantic Emmy as an associate producer with History Making Productions for a film about the 1793 yellow fever epidemic in Philadelphia. From 2010-2015 he was a contributor and staff journalist for the online news site, where he covered Wyoming state government and the University of Wyoming, including several stories on UW's migration research on mule deer and bighorn sheep. Greg holds a M.A. in history of the American West from the University of Wyoming and a B.A. magna cum laude from Carleton College.

As a masters' student I'm investigating the fall and spring spatial migratory pattern of tree bats (mainly eastern red bat) along the mid-Atlantic coast. Through trapping and affixing nanotags on bats throughout the region and tracking movement via stationary telemetry receivers, we hope to understand where bats choose to cross large bodies of water such as the Delaware Bay and Chesapeake Bay, and what climatic conditions persist while they do so. We also would like to understand migratory pathways over land as well as the effects sex has on migration in terms of space and time. This project was formed in response to growing wind energy development and future interest in development from coastal states in the mid-Atlantic region with funding from the Virginia Department of Game and Inland Fisheries.

My research interests center on freshwater mollusks with a focus on bivalves. I am interested in freshwater mussel distributions and population demographics, especially in under-sampled areas such as small, headwater streams. I also use GIS to conduct spatial analysis on freshwater mussels and their habitat preferences to predict their distributional limitations.
