EnviroThursday - "Historically Fishless Waters: A Habitat on the Brink?"

12:00 PM  - 1:00 PM
Thursday Feb 28, 2013
Olin-Rice Science Center 250

Speaker:  Emily Schilling, Environmental Studies Visiting Professor

Although the term “fishless lake” may conjure images of a lake devoid of life, naturally fishless lakes provide unique habitat for diverse assemblages of invertebrates and amphibians. Many of the organisms inhabiting fishless lakes are not adapted to coexist with fish. Widespread fish stocking has led to a worldwide decline in naturally fishless lakes and their associated communities. Little is known about the historical distribution of these freshwater ecosystems. In this talk, Emily will discuss a collaborative research project that combines GIS and paleolimnological techniques to identify historically fishless lakes. Remote detection of historically fishless lakes is useful for efficiently targeting lakes that are the best candidates for conservation and restoration. Emily will also discuss the effects of introduced fish on native aquatic fauna in historically fishless lakes.

Emily Schilling received her B.A. from Colgate University in Hamilton, NY, where she majored in Biology and French. After teaching in France on a Fulbright Teaching Assistantship, she worked at the Center for Biodiversity and Conservation at the American Museum of Natural History in New York City. She went on to get her M.S. and Ph.D. in Ecology and Environmental Science from the University of Maine in Orono. Emily recently started teaching at Macalester.
