TOM FROST - INSPIRATIONS, INTERACTIONS, AND INFLUENCES OF HIS CAREER ON RESEARCH IN THE ECOLOGY OF UV RADIATION.

The limnological community lost a valuable colleague in August of 2000 when Tom Frost tragically drowned in Lake Superior. An accomplished limnologist, and a thoughtful and generous person, Tom was perhaps best known for his leadership role in the whole-lake acidification experiments in Little Rock Lake and in the North Temperate Lakes LTER project. This talk will review some of the ways in which Tom's work in these lakes inspired work on the ecology of ultraviolet radiation (UVR) and climate change in lakes. In Little Rock Lake, acidification induced changes in dissolved organic carbon (DOC). DOC in turn controls the underwater UVR environment, suggesting that UVR as well as pH may be responsible for some of the changes commonly observed during anthropogenic acidification of lakes. Subjects to be discussed will include how DOC-mediated UVR may alter processes ranging from thermal stratification of the water column and vertical migration of zooplankton to changes in the community structure of predators and spawning depth of fish.
