USGS Scientist Invited Speaker at University of Washington
On April 26, John Piatt, USGS Alaska Science Center Research Wildlife Biologist, will present an invited talk in the School of Aquatic & Fishery Sciences Departmental 2012 Spring Seminar Series at the University of Washington, Seattle. The talk entitled "Predator response functions and the Ecosystem Approach to Fisheries" will discuss research on global seabird responses to forage fish depletion and the functional relationships between predator and prey. Managers need quantitative data on these relationships to identify "minimum biologically acceptable limits" of forage biomass to ensure the long term viability of these species as well as the societal and economic benefits they provide. Analyses of data from several marine ecosystems of the world suggest that response functions are usually non-linear and exhibit thresholds which may help us identify those "acceptable limits". This talk is open to faculty, students and the public.

New Publication on Identifying Causes of "Conflict" Between Nuclear and Mitochondrial DNA
On April 13, USGS Alaska Science Center scientist Lee Tibbitts answered questions for an article published April 16, in the Anchorage Daily News (Anchorage, AK). The article entitled "Migratory birds make spring official" discussed the spring migration of birds to Alaska.
On April 15, a radio piece on the long-term impacts of the Exxon Valdez oil spill was broadcasted on German Public Radio. USGS Alaska Science Center researcher Daniel Monson was interview by science reporter Monika Seynsche for this piece which focused on herring, but also included a segment on sea birds and see otters. The interview (in German) is now available online at http://www.dradio.de/dlf/sendungen/wib/1725498/ and the transcript (in German) is available at http://www.dradio.de/dlf/sendungen/wib/1729820/
