Great Lakes Science Center

Home

Welcome!  The Great Lakes Science Center (GLSC) is part of the Midwest region of the USGS. Our scientists work in the Great Lakes region and other parts of the country to meet the nation’s need for scientific information used by resource managers to restore, enhance, manage, and protect the living resources and habitats in the Great Lakes basin. 

Mapping Application for the Lower Maumee River (MALMR)

Mapping Application for the Lower Maumee River (MALMR)

The Mapping Application for the Lower Maumee River (MALMR) is intended to support science-based decision making regarding habitat restoration at various scales in the lower Maumee River and surrounding region.

Benthic habitat is an integral part of freshwater Mysis ecology

Diel vertical migration (DVM) is common in aquatic organisms. The trade‐off between reduced predation risk in deeper, darker waters during the day and increased foraging opportunities closer to the surface at night is a leading hypothesis for DVM behaviour.Diel vertical migration behaviour has dominated research and assessment frameworks for ...

Hypoxia augments edge effects of water column stratification on fish distribution

Hypoxic conditions in both freshwater and marine habitats have a significant effect on the distribution of fish in the water column, resulting in some fishes aggregating near the edges of the hypoxic zone. These aggregations may increase fish susceptibility to fishing gears, with attendant effects on stock assessment inferences. We investigated...

A synthesis of the biology and ecology of sculpin species in the Laurentian Great Lakes and implications for the adaptive capacity of the benthic ecosystem

The Laurentian Great Lakes have experienced recent ecosystem changes that could lead to reductions in adaptive capacity and ultimately a loss of biodiversity and production throughout the food web. Observed changes in Great Lakes benthic communities include declines of native species and widespread success of invasive species like dreissenid...
