Commentator - Field Notes

Gretchen Gerrish works for UW-Madison's Trout Lake Station through the Center for Limnology. She studies how evolutionary and ecological processes interact to allow natural systems to deal with change over time.

Most of her work focuses on zooplankton, microscopic invertebrates that provide the food-web link between fish and algae.
