SES Distinguished Scientist Seminar Series
11/04/05
From Killer Whales to Kelp Forests: Large Predators and Ocean Food Webs
James Estes, U.S.G.S. and U.C. Santa Cruz - 3:00 PM, Whitman Auditorium
James Estes is an expert on kelp bed ecosystems, and has conducted groundbreaking research on food web structure and the role of apex predators in controlling ecosystem structure and function. He has focused much of his work on the effects of sea otters in kelp ecosystems and published extensively on the near extinction and recovery of sea otter populations in the Aleutian archipelago and off the coast of California.
Dr. Estes is currently research scientist at the Western Ecological Research Center of the U.S. Geological Survey and is adjunct professor with the Center for Marine Studies at the University of California at Santa Cruz. He received his BA in zoology/chemistry from the University of Minnesota, MS in zoology from Washington State University and Ph.D. in biology and statistics from the University of Arizona. He was awarded the Betty S. Davis Conservation award for his work in protecting sea otters (1987), the U.S. Dept. of Interior Natural Resource Response Award for Exceptional Service (1990), and was designated a Distinguished Alumnus of the University of Arizona (1990). In 1999 he was named a Fellow of the Pew Marine Conservation program.
He has published more than 120 papers and serves on the editorial boards of the scientific journals Ecology, Marine Ecology Progress Series, Animal Conservation and Frontiers in Ecology and Environment. He is editor-in-chief of the journal Marine Mammal Science, and is editor of a fourthcoming volume, “Whales, Whaling and Oceanographic Ecosystems.” He is deputy chair of the World Conservation Union’s Otter Specialist Group for the Species Survival Commission.
