Services are pending for Gary P. Moberg, 58, a professor of animal science and of neurobiology, physiology and behavior at the University of California, Davis, who collapsed and died this morning while walking from the parking lot to his campus office. "Gary was a longtime faculty member in the animal science department to whom many of us turned for advice," said Gary Anderson, chair of the UC Davis Department of Animal Science. "He was internationally recognized as an expert in animal stress and animal welfare. He will be sadly missed as both a colleague and a friend." Born in Alexis, Ill., where he was raised on his family's farm, Professor Moberg was an animal physiologist who studied the ways in which environmental stresses influence the reproduction, health and behavior of animals. His early research focused on stress responses in monkeys, looking at how early life experiences affected their individual responses to stress. In the early 1980s, he broadened his work to address animal welfare issues. Researchers in his laboratory are currently studying how the endocrine system's response to environmental stresses affects ovulation and the expression of sexual behavior in individual animals. Research in the Moberg laboratory focuses on the endocrine control of reproduction in white sturgeon, the mammoth fish valued for both caviar and meat; on the biological response of fin-fish to stress; and on the impact of environmental stress on shellfish. Professor Moberg also had begun collaborating with the National Marine Fisheries Service, examining potential stress effects of certain tuna fishing practices on dolphins in the South Pacific. After earning a bachelor's degree in biology from Monmouth College in Illinois in 1963, he went on to earn a master's degree in behavioral physiology and a doctoral degree in neurophysiology, both from the University of Illinois, Urbana. After doing post-doctoral research in neuroendocrinology at UC San Francisco, he joined the faculty of the UC Davis animal science department in 1970. He most recently was teaching courses on comparative physiology and endocrinology and was a member of the graduate group in animal behavior and the graduate group in physiology, which he previously chaired. He served as associate dean of the Division of Animal Biology in the College of Agricultural and Environmental Sciences for the past six years. He left that post this spring to become director of the campus's Center for Aquatic Biology and Aquaculture. Believing strongly in the center model for advancing interdisciplinary research, he established new research centers focused on dairy science, animal welfare, range and forested ecosystems, genetic engineering of large animals, and aquatic biology and aquaculture. He also developed the Center for Special Programs that would serve as an incubator for new research programs and was instrumental in developing a new animal biology major. He was active nationally as chair of the board of directors of the U.S. Department of Agriculture's Western Regional Aquaculture Center and regional administrative adviser for the National Animal Genome Project. He was a member of the American Physiological Society, the American Society of Animal Science, the Endocrine Society, Sigma Xi and the Society for the Study of Reproduction. In addition to his professional activities, Professor Moberg thoroughly enjoyed traveling and made a habit of bringing back art objects from his travels. He found great satisfaction in regular workouts, jogging and sharing coffee with friends. He was an avid San Francisco 49ers fan and for many years ran the play clock for UC Davis Aggie football games. He is survived by his wife of 32 years, Sydney Moberg of Davis, and by a son, Philip Moberg of San Diego, and a daughter, Kirstin Moberg of Santa Cruz. The family requests that any memorial gifts be sent to the Gary P. Moberg Scholarship Fund, care of the Department of Animal Science, University of California, One Shields Ave., Davis, CA 95616-8687.
