Great Lakes Science Center
Welcome! The Great Lakes Science Center (GLSC) is part of the Midcontinent Region of the USGS, DOI Regions 3 and 5. 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.

Thermal habitat use of lake trout in Lake Erie Thermal habitat use of lake trout in Lake Erie
Understanding the thermal habitat use of fish populations is vital for effective rehabilitation or management, particularly in the face of climate change, given limited thermal tolerances of some species. In Lake Erie, lake trout (Salvelinus namaycush) rehabilitation efforts by means of stocking have been ongoing for four decades. However, high water temperatures and lengthening periods...
Serendipitous insight into pre-hatch microstructure formation in larval lake whitefish (Coregonus clupeaformis) otoliths Serendipitous insight into pre-hatch microstructure formation in larval lake whitefish (Coregonus clupeaformis) otoliths
Otoliths are useful tools to estimate daily age, growth, and ontogenetic shifts in the early life stages of fish, providing information to support management efforts. Little effort, however, has gone into the examination of pre-hatch increment development. To assess variation in pre-hatch otolith size and increment formation, lake whitefish (Coregonus clupeaformis) sagittal otoliths were...
A framework for estimating age and growth using sibship relationships inferred from genomic data A framework for estimating age and growth using sibship relationships inferred from genomic data
Pedigree reconstruction based on genomic data offers a novel approach for estimating age and growth in wild populations. However, frameworks that use reconstructed pedigrees to parameterize growth models have not been available. We developed a sibship age and growth framework and evaluated the approach using simulation and an empirical application to Sea Lamprey (Petromyzon marinus) age...
