UAS Sitka Natural History Seminar Series
Talk held April 18
“Black Oystercatchers: Their Ecology and History in Sitka Sound” was the topic of the a presentation in the Sitka Campus’ Natural History Seminar Series. The seminar took place at 7 p.m. on Thursday, April 18, in UAS Sitka Campus Room 229. The presentation was free and open to the community.
The guest speaker wa David Tessler, the regional wildlife biologist for the Alaska Department of Fish and Game’s Wildlife Diversity Program. Tessler, based in Anchorage, is responsible for projects throughout Southcentral and Southwestern Alaska, including the Wrangell and Alaska mountain ranges, Prince William Sound, the Kenai Peninsula, Kodiak Island, Bristol Bay and the Aleutian Chain. In addition, he has projects in Southeast and Interior Alaska, Canada and the Lower 48.
Tessler’s research interests center on biodiversity conservation. Tessler’s projects tend to focus on relationships between the vital rates of a species of concern and the array of threats encountered throughout the life cycle; population connectivity; genetic structuring; migratory behavior; and the implications of climate change.
In his more than 20 years as a field biologist (15 in Alaska), he has focused on a variety of species including the black oystercatcher, rusty blackbirds, wood frogs, loons and grebes, little brown bats, and alpine landbird assemblages. In addition, he has conducted research on the Pacific walrus in Alaska and Russian Far East. Tessler holds a master of science degree in biological sciences from the University of Alaska Anchorage, and a bachelor of science in wildlife biology from Colorado State University.
The UAS Natural History Seminar Series hosts several seminars during the school year on a variety of topics, including Southeast Alaska flora and fauna, glaciers, volcanoes, and impacts of climate change in the region. The series is supported by a grant from the Sitka Permanent Charitable Trust to the Sitka Sound Science Center and the University of Alaska Southeast.
