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.

Composition and distribution of fish environmental DNA in an Adirondack watershed
BackgroundEnvironmental DNA (eDNA) surveys are appealing options for monitoring aquatic biodiversity. While factors affecting eDNA persistence, capture and amplification have been heavily studied, watershed-scale surveys of fish communities and our confidence in such need further exploration.MethodsWe characterized fish eDNA compositions using...
Cornman, Robert S.; McKenna, James E.; Fike, Jennifer A. A structured approach to remediation site assessment: Lessons from 15 years of fish spawning habitat creation in the St. Clair‐Detroit River system
Ideally, restoration re‐establishes natural processes in degraded habitats (e.g., flow and sediment regimes). However, in altered systems where process‐based restoration is not feasible, habitat construction is another approach to mitigate degradation. Because habitat construction does not directly focus on restoring processes that build and...

Daunting amounts of microplastics are present in surface waters worldwide. A main category of microplastics is synthetic microfibers, which originate from textiles. These microplastics are generated and released in laundering and are discharged by wastewater treatment plants or enter surface waters from other sources. The polymers that...
