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.

Survival, healing, and swim performance of juvenile migratory sea lamprey (Petromyzon marinus) implanted with a new acoustic microtransmitter designed for small eel-like fishes

BackgroundLittle is known about the transformer stage of the parasitic lampreys, a brief but critical period that encompasses juvenile out-migration from rivers to lakes or oceans to begin parasitic feeding. Information about this life stage could have significant conservation implications for both imperiled and invasive lampreys. We investigated tag retention, survival, wound healing, and swim pe

Intra-specific variation in responses to habitat restoration: Could artificial reefs increase spatiotemporal segregation between migratory phenotypes of lake sturgeon?

Habitat restoration is an important tool used to conserve biodiversity and restore species, but its effects are notoriously difficult to predict. Although outcomes of restoration projects are usually assessed using indices of species abundance and diversity, phenotypic differences among individuals within species are likely associated with differing responses to restored habitats. Here, we use lak

Spatiotemporal segregation by migratory phenotype indicates potential for assortative mating in lake sturgeon

Migratory diversity can promote population differentiation if sympatric phenotypes become temporally, spatially, or behaviorally segregated during breeding. In this study, the potential for spatiotemporal segregation was tested among three migratory phenotypes of lake sturgeon (Acipenser fulvescens) that spawn in the St. Clair River of North America’s Laurentian Great Lakes but differ in how often

Phragmites Adaptive Management Framework – Active Adaptive Management

Non-native Phragmites australis (Common Reed) has become established across the Great Lakes basin, outcompeting native plants and degrading natural habitats. Phragmites is managed using a variety of resource-intensive techniques, yet effectiveness of treatment may vary due to infestation level, application methods, environmental conditions, or other factors. With the goal to reduce uncertainty in...

Innovative Approaches for Wetland Restoration and Invasive Species Management

Coastal and wetland ecosystems provide critical habitat to birds, fish, wildlife, and a suite of other organisms, clean our water and mitigate flooding events, and offer tremendous recreational opportunities to visitors. However, the majority of coastal and wetland ecosystems in the Great Lakes basin have been significantly degraded or destroyed by ditching, draining, development, invasive species...

Invasive Phragmites Science: Great Lakes Phragmites Collaborative and the Phragmites Adaptive Management Framework

Broad coordination is required to overcome large-scale regional challenges such as controlling a persistent invasive plant like Phragmites. Individual management actions may have local impact, but their implementation can be inefficient and landscape-scale impacts are limited. The highly successful Great Lakes Phragmites Collaborative builds collaboration and facilitates communication on a...
