Brave Wilderness host, Coyote Peterson, holds his hands in a tank of live sea lamprey while filming the first of two sea lamprey-focused episodes for the show’s YouTube channel. GLSC communications associate, Dr. Andrea Miehls, assisted the Brave Wilderness team while filming in multiple remote locations across northeastern Michigan.

Vessels like this use various sampling methods to collect fish at all life stages, adult, larvae, and eggs.

Nicole King (University of Toledo graduate student) holding a Grass Carp. The Ohio Department of Natural Resources and Michigan State University responded to a report from a commercial fisherman that grass carp were being captured in the Sandusky River. Researchers captured, tagged, and released grass carp to track their movements.

Tyler McGill (National Park Service) and GLSC ecologist Johanna Nifosi (Chesterton, Indiana) placing bee nests in forested parts of Indiana Dunes National Park. This collaboration between both agencies aims to understand how habitat traits influence native bee connectivity in the area.

Invasive dreissenid mussel-encrusted acoustic telemetry gear retrieved from Little Bay de Noc in Lake Michigan. Acoustic telemetry technology allows scientists to track fish movement throughout a water body, such as whitefish and walleye in the case of this project. However, the large network of receivers around the Great Lakes basin comes together through the Great Lakes
