The slippery season is in full swing, and many roads, sidewalks and parking lots are getting a heavy dose of salt to speed ice melt. All that salt has to go somewhere, however, and much of it ends up in our rivers and lakes. University of Wisconsin Limnologist Hillary Dugan studies salt’s impact on the […]
In past shows, the Perpetual Notion Machine has focused a lot on the dangers present in our Yahara lakes system. In tonight’s episode, we look beyond our backyard to the Great Lakes themselves. So, PNM’s Lincoln Tice talks with Peter McIntyre, Associate Professor and limnologist at UW-Madison’s Center for Limnology. He researches the ecology, evolution, […]
Madison’s lakes and beaches were closed recently due to a massive algal bloom present in the waters. The algae is toxic to many species, including humans, fish and other aquatic species. Lincoln Tice follows up our investigation into Madison’s lakes with a UW-Madison limnology professor, Jake Vander Zanden, to discuss the biological factors that are […]
Madison’s lakes and beaches were closed last week due to toxic algal blooms present in the lake. PNM’s Kai Brito speaks to the director of the UW-Madison Center for Limnology, Steve Carpenter, who says these blooms were one of the worst Madison has ever seen.
PNM’er Will Cushman attended and recorded a very fascinating presentation on the emergence of invasive Zebra mussels into Lake Mendota. So, on this pledge drive edition of the Perpetual Notion Machine, Will presents various clips from that talk given by UW-Madison limnologist Jake Vander Zanden. This talk was sponsored by the Clean Lakes Alliance, and […]
Producer Will Cushman talks with Steve Powers, one of the authors of a new study published in the journal Ecology Letters about life under winter ice in many of the world’s freshwater lake ecosystems. Powers is a postdoctoral researcher at Washington State University. He received his PhD in limnology and marine science from UW-Madison. They […]
