UC Davis professor Randy Dahlgren will talk about volcanic rivers that provide habitat for cold-water fish species at a meeting Thursday of the UC Davis Emeriti Association and the UCD Retirees Association. The public is welcome.
Dahlgren, the recipient of the 2012 UCD Prize for Undergraduate Teaching and Scholarly Achievement, is a professor in the department of land, air and water resources.
Critical habitats for salmon and other cold-water species likely will diminish as global climate change reduces the amount of cold water in summer streams, Dahlgren says. He will discuss his research showing that volcanic spring-fed streams may provide adequate flow and vital nutrients to these cold-water species.
His talk will begin at noon Thursday at International House, 10 College Park in Davis. Admission is free and no pre-registration is required. Come as early as 11:30 a.m. with a brown-bag lunch. The associations will provide coffee, tea and cookies.
Parking is available in the I-House parking lot. If the lot is full, street parking permits are available from inside the I-House. Bicycling or walking are encouraged.
