Miami ecologists: UV radiation has detrimental and beneficial effects on freshwater ecosystems
Recent research has shed light on the beneficial, as well as detrimental, effects of ultraviolet radiation (UV) on individual organisms, and thus on natural ecosystems, according to Miami University ecologists.
Williamson, a member of the Environmental Effects Assessment Panel of the United Nations Environment Program, says the panel is monitoring how stratospheric ozone, which shields organisms from the most damaging wavelengths of UV, and the beneficial and damaging effects of UV are changing over time.
Rose was part of an expedition in 2008 funded by the NASA Astrobiology Institute in Chile and Bolivia to document the impact of rapid climate change on high altitude lakes in the Central Andes, considered “hot spots” of global warming and its effects. He is also involved with the Global Lake Ecological Observatory Network (GLEON), recently as chair of the GLEON Student Association.
Williamson’s research focuses on understanding the role of UV radiation in aquatic systems and the effects of climate change on lakes. His work is centered on alpine and subalpine lakes in the Beartooth Mountains of Montana and Wyoming; the Canadian Rocky Mountains; Lake Tahoe in California; and lower elevation lakes in Pennsylvania and reservoirs in Ohio.

He is a member of Miami’s Center for Aquatic and Watershed Studies (CAWS), a proposed Center of Excellence of the University System of Ohio.
