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)
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.

Elucidating controls on cyanobacteria bloom timing and intensity via Bayesian mechanistic modeling
The adverse impacts of harmful algal blooms (HABs) are increasing worldwide. Lake Erie is a North American Great Lake highly affected by cultural eutrophication and summer cyanobacterial HABs. While phosphorus loading is a known driver of bloom size, more nuanced yet crucial questions remain. For example, it is unclear what mechanisms are...
Del Giudice, Dario; Fang, Shiqi; Scavia, Donald; Davis, Timothy W.; Evans, Mary Anne; Obenour, Daniel R Evidence of an extreme weather‐induced phenological mismatch and a local extirpation of the endangered Karner blue butterfly
In 2011, an experiment was undertaken to examine spring synchrony between the endangered Karner blue butterfly (Lycaeides melissa samuelis) (Kbb) and its obligate host plant, wild blue lupine (Lupinus perennis) at Indiana Dunes National Lakeshore (INDU), where the southernmost population of Kbb occurred at the time of this study. From 2012 to 2014...
Patterson, Tamatha; Grundel, Ralph; Dzurisin, Jason D. K.; Knutson, Randy L.; Hellmann, Jessica Nanopore amplicon sequencing reveals molecular convergence and local adaptation of rhodopsin in Great Lakes salmonids
Local adaptation can drive diversification of closely related species across environmental gradients and promote convergence of distantly related taxa that experience similar conditions. We examined a potential case of adaptation to novel visual environments in a species flock (Great Lakes salmonids, genus Coregonus) using a new amplicon...
