“Hi All!

For the past six weeks, I have been working on collecting data for my first season and it has been super exciting! Fieldwork is much more intense and exhausting than you can imagine, but at the same time it is really fun and I have learned so much. I got to see amazing frogs, snakes, monkeys, birds, sloths and even humpback whales during my visit! I also realized that I am the luckiest person to be able ...

Tony Timpano’s proposal funded by OSM: stream ecosystem responses to surface mining

A project proposal submitted by IGC graduate student, Tony Timpano, to the Department of Interior’s Office of Surface Mining has been successful! This funding will support one full-time research associate for 12 months and one graduate student for two semesters to continue research on salt pollution (salinization) and selenium in headwater streams affected by coal mining in VA and WVA. Congratulations, Tony!

From VT News

As the clock ticks, populations of endangered species decline and threaten the functioning of healthy ecosystems.

Pollution, hunting, habitat degradation, climate change, and invasive species have dealt blows to global biodiversity. Climate change alone is putting one in six species on Earth at risk of extinction, according to a meta-analysis of 131 ...

Ben Vernasco studies the social dynamics and physiology of dancing birds

From Fralin Spotlight

by Cassandra Hockman

Ben Vernasco knew he wanted to pursue a Ph.D. in conservation biology while studying tropical birds in Peru. After his trip, he got in touch with his mentor, Brandt Ryder, a research ecologist at the Smithsonian Migratory Bird Center at the Smithsonian National Zoological Park in Washington, D.C.

Ryder and his Virginia Tech colleague Ignacio Moore, an associate professor of biological sciences in the College of Science, had just received a National ...

Tony Timpano is investigating the impacts of coal mining on Appalachian streams

Tony Timpano is an IGC student and a Ph.D. candidate in Forest Resources and Environmental Conservation. His field research is centered in the Appalachian “coal country” of southwestern Virginia and southern West Virginia.

Tony is interested in understanding how coal mining affects stream water quality and aquatic life. Ultimately, he hopes that his research findings will help guide policies on monitoring and managing salt pollution in streams.

“I want to improve the science of water quality management to enhance the capability of regulators to ...
