The Landscape Ecology Team is using acoustic and satellite telemetry to elucidate migration behaviour and stock structure of the green sturgeon, a highly migratory but poorly known species of growing conservation concern. This work is a collaboration with the NMFS Northwest Fisheries Science Center, Pew Institute for Ocean Science, Yurok tribal Fisheries, the Washington and Oregon Departments of Fish and Wildlife, and UC Davis, among others.
Using the same acoustic telemetry technology, we are studying migration and survival of juvenile Chinook salmon and steelhead in the Sacramento River. Poor survival during this stage of life is suspected to be a factor in the decline of salmonids in the Central Valley, and we hope to identify mortality "hot spots", which might be high-priority areas for habitat restoration. This work is in collaboration with scientists in the Salmon Ocean Ecology Team and the Department of Wildlife, Fish and Conservation Biology at UC Davis, and is supported by the CALFED Science Program.
