Q&A: Marine Ecosystems Research at the USGS Alaska Science Center
The USGS Alaska Science Center is a leader and collaborator in marine ecosystems research on topics ranging from ocean bottom-dwelling invertebrates and small pelagic forage fish (food for Pacific walrus, sea otters, and marine birds) to polar bears (an apex predator in the Arctic). Here, we highlight current research by the USGS Alaska Science Center that focuses on marine ecosystems of Alaska.
Loon Research
Scientists at the USGS Alaska Science Center have conducted research on Alaska’s three loon species since the late 1970s. Loons rely on freshwater lakes for nesting habitat and fish and invertebrates inhabiting lakes and marine ecosystems for food. All three loon species in Alaska occur within the National Petroleum Reserve-Alaska (NPR-A) on Alaska’s northern coast. Research by the USGS is...
Does fish prey influence red-throated loon productivity?
This study will evaluate the nearshore marine feeding areas of breeding adult red-throated loons and assess the response of loon reproductive success to differences in the relative abundance, composition, and nutritional content of nearshore fish communities that vary in space and time.
