Kelly McIntyre. Spring 2019.
I received my bachelor’s degree in Environmental Science from Dickinson College. During my time at Dickinson I worked at the Alliance for Aquatic Resource Monitoring (ALLARM) as a watershed coordinator. At ALLARM I educated school groups on watersheds, trained volunteer stream monitors on equipment, field and data management techniques, as well as ran quality assurance tests on water samples. After graduation I worked for 4.5 years as an entomology technician at Stroud Water Research Centre where I sampled and identified macroinvertebrates to species level for stream bioassessments. My general interests include aquatic food web ecology and reciprocal flows at the land-water interface. My research focuses on how natural and anthropogenic disturbances interact to influence aquatic macroinvertebrate community composition and function. More specifically, I will be looking at the impacts of atmospheric acid deposition and subsequent stream liming on macroinvertebrate secondary production in headwater streams of Shenandoah National Park.
Awards received : Honorable Mention- National Science Foundation Graduate Research Fellowship Program (NSF GRFP). Society for Freshwater Science Endowment Award - SImpson Fun, Grayson Outstanding Master's Student Award - Virginia Tech Entomology Department, W.B. Alwood Extension Award.

Aryanna James. Spring 2019.
I received my bachelor’s in Biology with a concentration in Ecology from Shippensburg University in Shippensburg, Pa. As an undergraduate there, I had some exposure to field and lab work associated with a study of the effects of direct application liming on acidified headwater streams. After graduating, I moved to Virginia and volunteered and interned at the Virginia Museum of Natural History located in Martinsville, Va. I helped digitize and organize the museum’s extensive Triassic fossil insect collection in which thousands of specimens are preserved with such great detail that even soft tissues, such as wing venation, can be seen. In addition, I assisted in molding and casting projects producing replica bones of ice age mammals. My focus in the Entrekin Lab is to look at how anthropogenic salinization affects the structure and function of macroinvertebrate communities in headwater streams. Studying this relationship will provide insight into how overall stream function is impacted. Functional capacity of a water body can, in turn, determine the services it can offer.

Abigail Belvin. Fall 2020.
I received my bachelor’s degree in Biology and Environmental Science & Policy from William & Mary. While there, I worked on ecology studies as well as broader climate change topics. My earlier research focuses were primarily on carbon sequestration and emission from forested areas and retention ponds respectively, while my later experience focused on ecological surveys of invasive plant species and the Diamondback Terrapin population in the York River. My interests include macroinvertebrate ecology and dynamics, in addition to the implications that policy can have on those dynamics. My research in the lab focuses on how to predict how best management practices impact insect biodiversity in the Chesapeake Bay watershed. This will help understand how effective the current best management practices are, and how freshwater stream ecosystems are responding to them.
