Dr. John Turner is an endocrinologist (Ph.D., Cornell; Postdoctoral, U.C.L.A., School of Medicine) with extensive expertise in reproductive biology and stress physiology. As a Professor of Physiology engaged in teaching and research, he has trained 18 M.S. and 7 Ph.D. students and has served on the thesis committee or as medical student/undergraduate honors research advisor for 39 other students. His teaching has also included directorship of the core course of the Molecular Basis of Disease graduate program and of the medical curriculum Endocrine system, Reproductive system and Human Sexuality Program. His research endeavors have included sexual differentiation of the brain (NIH, 1971-1984), wildlife contraception (U.S. Department of Interior, 1979-present), psychophysiology of human stress-related disorders and their treatment (private funding, 1979-1999) and effects of chronically deteriorating habitats on stress levels of wildlife and fishes (HSUS, private and zoo funding, 1991-present). The impetus for the wildlife studies has been the need to alleviate suffering faced by numerous species which are overpopulating fixed-size habitats. The stress studies have been motivated by need to assess the impact of increasingly compromised environments on the homeostasis of their inhabitants and to develop physiological early-warning indicators to red-flag such environments. A hallmark of his environmental endeavors has been the development of humane, non-invasive (remote) methods for both contraception and physiological monitoring of free-roaming wildlife. Dr. Turner’s research efforts have involved collaboration with investigators at 10 U.S. and 4 foreign universities and have yielded 102 peer-reviewed publications, including 6 books (editor). He has served for 19 years on Management Planning Committees of the U.S. Forest Service related to wildlife management, and in 2005 he received the U.S. Forest Service Chief Award (given to one person annually) for this work. He regularly reviews manuscripts for several peer-reviewed journals and grant proposals for NIH, NSF and USDA on an ad hoc basis. He has served as a wildlife contraception management consultant for 20 parks and preserves worldwide and for more than 25 urban/state preserves in the U.S. He is a long-time Research Associate at the Toledo Zoo and is a member of the Toledo Zoo Animal Care Committee. Since 1999 his research studies have primarily focused on a single-injection, multi-year controlled-release wildlife contraceptive vaccine and on environmental stress assessment in fishes via fecal cortisol measurement. In 2006 he was the recipient of the Medical University of Ohio Career Sustained Research Award.
