Jim Estes Adjunct professor of ecology and evolutionary biology University of Ca, Santa Cruz Jim, a research biologist with the USGS Western Ecological Research Center, is based at UCSC's Center for Ocean Health at Long Marine Laboratory. He is well-known nationally and internationally for his research on sea otters and the key role they play in kelp-forest ecosystems. The USGS award citation outlined the many ways in which he has worked with the media to publicize his findings about sea otter populations. Through his research and communications efforts, Jim has made widely known the fascinating story of the precipitous decline of sea otters in Alaska, the discovery that killer whales were preying on otters, and the subsequent chain reaction that resulted in the loss of entire kelp-forest ecosystems. He first published his findings in the journal Science in 1998, then went on to capture the public's attention around the world by telling his story through newspaper, magazine, radio, and television media, including the New York Times and Washington Post, the Associated Press, Reuters, ENN News, National Geographic magazine, NBC Nightly News, MSNBC, National Public Radio, CNN, ABC, and the Canadian Broadcasting Company. Among his many awards, Jim received the Shoemaker Award for Distinguished Achievement in Communication from the U.S. Geological Survey (USGS).

James Estes, PhD Dr. James Estes is an international expert on sea otters and a specialist in the critical role of apex (top level) predators in the marine environment. He has been a research biologist at the Western Ecological Research Center of the U.S. Geological Survey for more than 20 years. Estes also holds academic posts as research associate and adjunct professor with the Center for Marine Studies at the University of California, Santa Cruz.
His interest in predation as an ecosystem-level process began in the early 1970s, after he began working with sea otters. Using the otters' fragmented distribution across the Aleutian archipelago (which resulted from a history of near-extinction and recovery), he and a colleague discovered the species' keystone role in kelp forests by comparing islands where it was abundant or rare. This work provided a spectacular example of how apex predators influence ecosystem functions. Estes continued to explore the dimensions of sea otter-kelp forest interactions over the next 30 years, including the unanticipated collapse of sea otters and kelp forests in western Alaska.
He has now published nearly 70 scientific articles and reports on wildlife ecology, predation and conservation, and was lead editor of the 2007 book, "Whales, Whaling, and Ocean Ecosystems. Estes is a recipient of the prestigious Pew Fellowship in Marine Conservation (1999).

James A. Estes
After growing up in southern California, Jim received a bachelor's degree from the University of Minnesota in 1967 and doctorate from the University of Arizona in 1974. He subsequently worked as a research scientist for the Fish and Wildlife Service and the US Geological Survey. After retiring from federal service in 2007, Jim took a part time faculty position with the Department of Ecology and Evolutionary Biology at the University of California at Santa Cruz, where he currently resides. Jim is an internationally known expert on marine mammals and a specialist in the critical role of apex (top level) predators in the marine environment. Much of this work has been with sea otters and coastal ecosystems in the North Pacific Ocean. Jim has conducted field research in Alaska, California, Mexico, New Zealand, and Russia. He has published more than 150 scientific articles, several books and monographs, and has served on the editorial boards for a variety of professional journals. He also served on the California and southwest Alaska sea otter recovery teams. Jim's most recent book, published by Island Press in 2010, is a co-edited volume with John Terborgh entitled Trophic Cascades: Predators, Prey and the Changing Dynamics of Nature.

Jim is a Pew Fellow in marine conservation and a Fellow of the California Academy of Sciences. He received the Western Society of Naturalist's Lifetime Achievement Award in 2011 and the American Society of Mammalogists' C. Hart Merriam Award in 2012.

Professor James Estes, an expert in the population dynamics of sea mammals at the University of California, Santa Cruz, believes that, faced with a shortage of food, some groups of Pacific orcas have altered their diets. Each killer whale is capable of eating several otters or seals a day.
Estes, whose research will be published in the Philosophical Transactions journal of the Royal Society, said: "Killer whales are the world's largest carnivores.
...
Estes is very cautious about such ideas, partly because he believes the science needs to be more certain and because pred-ator control programmes are seldom successful. A cull would also cause an outcry among conservationists.
"Culling killer whales might solve the problem but it would have a huge political dimension. A lot of people involved in conservation are nervous about this issue," he said.
Estes, however, remains deeply concerned that the current population levels of sea otters, Steller's sea lions and some seal species is so low that they are at risk of extinction. Although exact numbers are unknown, the population of these species has dwindled to about 10,000-20,000, a fraction of their natural levels.
Such animals were intensively hunted for their fur, oil, meat and blubber from the 18th century onwards but their numbers began to recover after they were all given protection in the early 20th century.
Last century, however, industrial whaling wiped out most of the great whale populations in the Pacific, Atlantic and Southern Ocean. "It seems likely that killer whales expanded their diets to include a higher percentage of sea otters and other sea mammals after the reduction in great whale numbers caused by postworld war two industrial whaling," said Estes.
