The food web in Great Plains streams could be unraveling, according to a Kansas State University ecologist.

Keith Gido, professor of biology, and Josh Perkin, a Kansas State University alumnus, recently published "Groundwater declines are linked to changes in Great Plains stream fish assemblages" in the Proceedings of the National Academy of Sciences. The research maps the loss of stream habitat for many small fish in the Great Plains region and attributes it to declining groundwater sources.
