North Temperate Lakes Long Term Ecological Research studies the ecology of lakes as one of a network of sites established by the National Science Foundation. We are interested in how biophysical setting, climate, and changing land use and cover interact to shape lake characteristics and dynamics over time (past, present, future).
Our primary study sites include a set of seven northern Wisconsin and four southern Wisconsin lakes and their surrounding landscapes. The project, which started in 1981, is administered by the Center for Limnology at the University of Wisconsin-Madison.
In recent years, exotic fish species in the upper Great Lakes watershed continue to expand their range and are having substantial negative effects on native fishes. A particular exotic, the rainbow smelt (Osmerus mordax), is spreading rapidly in the upper Great Lakes region. Changes in the native fish communities have followed the smelt invasions; this species impacts native fishes directly through predation and indirectly through exploitation competition ....
