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.
Shallow fertile lakes characteristically are turbid with dense algae and few submersed macrophytes when benthivorous fish such as carp are overabundant. These lake conditions often represent a “stable state” until benthivorous fish densities are reduced either by natural die-offs (e.g., winterkill) or through management efforts. Many shallow lakes have been “restored” to a clear-water, aquatic macrophyte state by whole-lake carp eradications, but such chemical treatments are not always effective due to lake size or interconnecting waters. And in urban settings, chemically eradicating fish is sometimes not even possible due to public opposition ....
