FSUCML Lecture Series

July 11, 2013

 

Thursday, July 11, 2013 7 PM 

FSUCML Auditorium

Antarctica is often referred to as the last pristine environment; however, an increasing body of evidence suggests this is inaccurate. Circumpolar long-term research indicates that recent changes in the global climate, driven by human influences, are particularly acute in Antarctica.  For example, warming of the regional climate has been correlated with disturbances throughout the sea-ice dominated ecosystem along the Western Antarctic Peninsula.

A lesser studied human impact on the Antarctic ecosystem is the presence of persistent organic pollutants, such as DDT, in apex predators like the Adélie penguin.  DDT has not declined in Adélie penguins from the Western Antarctic Peninsula for more than 30 years indicating that there is a current source of DDT to the Antarctic marine food web. Dr. Geisz will discuss the likely source for this DDT along with the broader impacts of climate change on Adélie penguins and their icy habitat.
