Food Web Analysis
Food Web Analysis
Environmental managers across the basin make critical management decisions based on their understanding of how Great Lakes food webs work. The GLSC conducts research to elucidate the impacts of species on other species and on food webs as a wholes. Some research seeks to clarify whether food webs are shaped more by conditions or species near the bottom of the food web or by predator species at the top. Other research seeks to clarify the relationship between, for example, aquatic and terrestrial food webs. Models generated from these studies improve environmental management decisions, leading to more predictable outcomes.

Development and application of a robot-assisted computer vision system to map Great Lakes bottom habitats and biology
Lake bottom environments are critical zones of interface between geology and biological processes that support health ecosystems and human well-being. Over the past thirty years, Great Lake food webs have become dominated by bottom dwelling invasive species and nuisance algae, that are poorly mapped and understood. USGS is developing a suite of new technologies to map habitat, invasive mussels and...
