Should I Stay, or Should I Go: Tracking Partial Migration Frequency of Yellow Perch (Perca flavescens)

Studying fish comes with many challenges, and one of the biggest is that they are constantly on the move. Because of this, tracking fish has become a major focus in aquatic science in recent years. With tools like acoustic telemetry, scientists can now monitor fish movement at both fine and large spatial scales.

Much like how cell towers use signals to track phones, a network of receivers can record the movements of individual fish over time. Scientists use this technology to study yellow perch in Lake Michigan, a species that is important to both the ecosystem and local fisheries.

Join Anna Hill for an overview of her work tracking fish. Originally from Chicago, Hill is a master’s degree student at Purdue University co-advised by Tomas Höök and Paris Collingsworth. She completed her undergraduate degree in marine science from the University of Delaware. She has worked as an aquatic technician in both freshwater and marine systems.

10,000 Years of Archaeology Below the Great Lakes

Ashley Lemke will discuss underwater archaeology and the Great Lakes.

The Great Lakes of North America were once at much lower water levels, and during these times, people, plants, and animals inhabited shorelines that are now submerged. Underwater archaeological research has revealed that 9,000 years ago people were hunting animals and using stone tools on the Alpena-Amberley Ridge, a feature that now lies 100 feet beneath the waves of Lake Huron.

Join Ashley Lemke, an Associate Professor of Anthropology at the University of Wisconsin–Milwaukee, for an overview of her work as an archaeologist on land and underwater.

Lemke is an internationally recognized expert for her innovative work in underwater archaeology and commitment to expanding the frontiers of archaeological science through technology, collaboration, and education.
