Jo Latimore’s interest in aquatic ecology dates back to her childhood, spending time at her parents’ North Michigan cabin, exploring the water nearby. Today she is a senior academic specialist, aquatic ecologist, and outreach specialist at Michigan State University in the Department of Fisheries and Wildlife , in her thirteenth year in the position. Latimore’s primary interests include lake appreciation and engagement.
“Most people appreciate our lakes. They like to look at, fish on, and boat on them. However, they don’t necessarily appreciate our lakes as an ecosystem,” Latimore said. “It’s the health of the lakes that lets us use them recreationally.Read More
An early aquatic science pioneer, Luna Leopold, said that “The health of our waters is the principal measure of how we live on the land.” Determining how the land impacts water quality, however, is complex. There must be an understanding of the flow of materials, organisms, and energy within our waters and how they are connected, or even whether they are connected. Enter the emerging field of aquatic systems connectivity.Read More
Lakes are subject to many forces, large and small, from the climate to the presence or lack of individual chemicals and their movements in the lake system. One of the many forces acting on lakes is bacterial action, which is a major player in phosphorus, nitrogen, and carbon cycling in lake systems. These, in turn, influence eutrophication and water quality in lakes.
Trina McMahon, professor of civil and environmental engineering at the University of Wisconsin-Madison , described how bacteria affect cycling of these three major chemical elements in lake systems, and how lake health is impacted.
