Great Lakes Science Center

Welcome!  The Great Lakes Science Center (GLSC) is part of the Great Lakes Region 3 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.

Local diversity in phenological responses of migratory lake sturgeon to warm winters

Rich intraspecific diversity in traits that shape responses to environmental conditions implies that effects of climate change will differ within species or even populations. Nevertheless, few studies investigate how different groups within species respond to climatic fluctuations, and most risk assessments rely upon species-wide generalizations. We studied effects of among-year variation in air t

Towards improving an Area of Concern: Main-channel habitat rehabilitation priorities for the Maumee River

The Maumee River watershed in the Laurentian Great Lakes Basin has been impacted by decades of pollution and habitat modification due to human settlement and development. As such, the lower 35 km of the Maumee River and several smaller adjacent watersheds comprising over 2000 km2 were designated the Maumee Area of Concern (AOC) under the revised Great Lakes Water Quality Agreement in 1987. As part

Microbial source tracking and evaluation of best management practices for restoring degraded beaches of Lake Michigan

Attempts to mitigate shoreline microbial contamination require a thorough understanding of pollutant sources, which often requires multiple years of data collection (e.g., point/nonpoint) and the interacting factors that influence water quality. Because restoration efforts can alter shoreline or beach morphology, revisiting source inputs is often necessary. Microbial source tracking (MST) using so

Grass Carp in Lake Erie

Grass Carp, commonly used in aquaculture to control plant growth, escaped captivity in the Mississippi River and have been in the Great Lakes since 1975. Spawning surveys have documented spawning since 2015 in the Sandusky River leading to expanded surveys and an effort to confine reproduction to the western part of Lake Erie.

Coregonine restoration in the Great Lakes- David Bunnell

The principals of conservation biology are waiting to be applied to restore native coregonines in the Great Lakes. Native fishes have suffered extinctions and extirpations owing to loss of habitat, interactions with invasive species, and overfishing, and now fishery managers are committed to their restoration.
