Underwater Electric Activity LectureA lecture by Warren Wisby and R. [?] Pierce including recordings of the electrical activity of the electric eel (Electrophorus electricus). Wisby was a graduate student with Arthur Hasler on the action of salmon. Audio cut off at 21:51 because the rest of the tape was classical music and thus unrelated to the lecture. Cuts off at 00:23:00 and turns into classical music.Wisby, Warren; Pierce, R.19590:30:30Audio

Introducing Wisconsin’s Initiative on Climate Change ImpactsDick Lathrop, a research limnologist with the Wisconsin Department of Natural Resources and former CFL PhD student with Steve Carpenter, gives a talk introducing the Wisconsin Initiative on Climate Change Impacts, which focuses on the effects of climate change on Wisconsin. Discusses several effects of a warming climate, including warmer bodies of water, increased effects of pollution, increases in spread of various diseases, impact on winter recreation impact on cold-adapted wildlife and plantlife, increase in invasive-species issues, increase in freezing rain and freeze-thaw events. more unpredictable and extreme weather and impacts on agriculture. Goes on to talk about WICCI and, its structure, and its goal to help Wisconsin adapt to climate change. Gives examples of adaptation strategies.Wisconsin Public Television20090:32:14Video
Wisconsin’s Cool & Warm Water Fish and Climate ChangeJohn Lyons, a research scientist with the Wisconsin Department of Natural Resources and former CFL PhD student with John Magnuson, gives a talk on the effects of the warming climate on Wisconsin fish. Goes over projections for how climate change will affect stream temperatures in Wisconsin. Compares effects on coldwater, coolwater, and warmwater fishes. Talks about effects of warmer water on bodies of water, such as poorer water quality, more invasive species, more erosion, flooding, and more.Wisconsin Public Television20090:23:03Video
Wisconsin Lakes and Climate ChangeJohn Magnuson, Professor Emeritus of Zoology and former Director of the CFL, gives a talk on several of effects of climate change on Wisconsin lakes, specifically ice cover, fishes, and water levels and flows.Wisconsin Public Television20090:36:04Video
CLMN Webinar Series – Lake Ice: the invisible present and placeJohn Magnuson gives a webinar talk for the Citizen Lake Monitoring Network on lake ice and the invisible present and place.

My Life in Science: History, Thoughts, and Choices from 1950 to 2022John Magnuson gives a talk for the CFL seminar series on his 60 career at UW-Madison and before. Gives a brief overview of the history of limnology at UW-Madison, talks about the importance of his family in supporting his career, time in Hawaii, and how he made his educational and professional decisions, including why he chose to stay at UW-Madison and form the Center for Limnology. Discusses his teaching, advising, and research experience as a faculty member in a major research university. Talks about some of his former graduate students, publication history, change in ways of publishing, citation trends for his publications, outreach, professional service, including working on the Intergovernmental Panel on Climate Change.Magnuson, John20221:02:37Video
Conversations in Science: Climate Change and Waters of Wisconsin at Edgewood CollegeJohn Magnuson gives a talk to teachers at Edgewood College on climate change and the effects it has on Wisconsin’s bodies of waters. Discusses how we as people are much better at dealing with shorter-term problems than the long-term problems that develop slowly and his related idea of the “Invisible Present” making it difficult for us to see long-term changes in the environment. Talks about some of the evidence for human-caused global warming from the Intergovernmental Panel on Climate Change.Madison Metropolitan School District2008-04-181:29:06Video
