Climate impacts on coastal ecosystems

Location: 11:00 am to 12:00 pm in Building 6, Level C, Room 12

Society’s greatest environmental challenge is confronting the impacts of climate change. In this talk, I present and discuss evidence that coastal climate change has already had impacts on coastal ecosystems. Coastal climates have changed in multiple ways. Upwelling has intensified, wave height has increased, oceanic water temperature has increased while coastal water temperature has decreased, oxygen levels in the ocean have decreased, and coastal waters have become more acidified and less amenable to calcification of marine organisms. Associated with these environmental changes are ecological changes: globally, declines in mussel abundance and decreases in macroalgae abundance have occurred. Along the US west coast, thermally-linked declines of many taxa have occurred, as have declines associated with changes in oxygen and CO2 such as dieoffs from hypoxia, relocations of fish populations, and failure of oyster recruitment.

Bruce A Menge is a Distinguished Professor of Integrative Biology and the Wayne and Gladys Valley Endowed Professor of Marine Biology at Oregon State University. He served as Chair of the Department from 2008-2011. His major research areas are marine community, meta-community and meta-ecosystem ecology, and physiological ecology, and he is currently focused on the impacts of climate change, including ocean acidification, on coastal marine ecosystems. He is the lead PI in PISCO, the Partnership for Interdisciplinary Studies of Coastal Oceans, and in OMEGAS, the Ocean Margin Ecosystem Group for Acidification Studies. He is a member and Fellow of the American Association for the Advancement of Science, and of the Ecological Society of America, and a member of the American Society of Naturalists.
