January 14: Dr. Sarah Hobbie, Distinguished McKnight University Professor in the Dept of Ecology, Evolution, and Behavior. Her research addresses the influence of changes in atmospheric composition, climate, land use, and plant species composition on communities and ecosystems, and the effects of urbanization on biodiversity and water quality.
In this talk, Dr. Hobbie will describe her research on quantifying the sources of nutrient pollution to urban watersheds. This is one of her many research areas and that of her lab of graduate students and post-docs. She will address how nutrients enter the watersheds of the Mississippi River and how they move from urban residential landscapes into streets, then stormwater, and ultimately into streams, lakes, and rivers. She will also discuss approaches to reducing nutrient pollution of our urban waters, including ongoing work in partnership with the MN Pollution Control Agency. We are fortunate that Dr. Hobbie has agreed to speak to SPAS about this long-term problem — bringing the findings of her university research to us, the citizens who can help address water quality through our own practices.
Dr. Hobbie’s research focuses on the influence of changes in atmospheric composition, climate, and land use on communities and ecosystems, and on the effects of urbanization on biodiversity and water quality. She currently serves as co-leader of the Cedar Creek Long-Term Ecological Research program. She is a member of the National Academy of Sciences and an American Academy of Arts and Sciences Fellow. She serves on the Advisory Board of the Earth Leadership Program and on several editorial boards.
