I have a Ph.D. in biology from the University of Oregon where I conducted research with Dr. Robert Terwilliger on the reproductive physiology of viviparous fish at the Oregon Institute of Marine Biology. I subsequently conducted postdoctoral work on nutrient transfer processes in the human placenta with Dr. John Bissonnette in the Department of Obstetrics and Gynecology at Oregon Health Sciences University.

I came to the University of Idaho in 1986 and have worked on a variety of scientific projects examining placental transport of ascorbic acid, the reproductive physiology of viviparous snakes (garter snakes and rattlesnakes), the properties and function of salamander egg jelly, and the effects of the pesticide, methoxychlor, on the development and physiology of the long toed salamander, Ambystoma macrodactylum.

Over the last 7 years, however, I have focused my research efforts primarily on the physiology of fish and their gametes. This focus is based on my background interest in fish biology and the unique opportunities for conducting research on the endangered and threatened fishes of this region.

My research focuses on the influence of environmental stressors on fish gamete physiology as reflected by ionic perturbations. The mechanisms maintaining or altering gamete viability are of special interest.

I am a first year PhD student with a MS in Endocrinology from The Mumbai University, India.  My research interests are to assess the toxicological impacts of various agents on fish gamete physiology.

Michael Holcomb

Michael Holcomb
 

Michael has worked on several projects in this lab during his time at the University of Idaho.  He is the first author (along with Josh Woolsey, Dr. Joseph Cloud, and Dr. Rolf Ingermann) on a manuscript just submitted to the North American Journal of Aquaculture on the effects of MS-222, clove oil and carbon dioxide anesthesia on steelhead eggs and sperm.  He is also writing up a study in which he examined the oxygen consumption of unfertilized salmonid eggs relative to their fertility.  Finally, he was a coauthor on a paper published in the Journal of Experimental Biology on the effects of pH and carbon dioxide on function of sperm from an endangered population of landlocked white sturgeon.  His heart is in coral biology and he is currently investigating Ph.D. programs.

While completing her M.S. program with Dr. John Byers on pronghorn behavior, Mary worked with us for a year assisting with two major projects. She assisted with studies of the effects of pH and carbon dioxide on the sperm of an endangered sturgeon.  She also established the methodology to measure salmonid sperm respiration and then generated the core data of a study recently published in the Journal of Fish Biology.

Salmonid sperm maintained under low pH conditions prior to water activation demonstrate no motility upon water dilution whereas sperm maintained at elevated pH do become motile upon water dilution. The basis for this pH sensitivity is not clear. Josh examined the pH sensitivity of dynein ATPase activity (the molecular motor that propels sperm) relative to the intracellular pH of the sperm. His findings indicate that the pH sensitivity of dynein ATPase contributes to but cannot account for this pH sensitivity. This work has been submitted for publication to Fish Physiology & Biochemistry. As a side project, he and Michael Holcomb (see above) examined the effects of temperature and clove oil anesthesia on steelhead fry. This work is now in press with the North American Journal of Aquaculture. Josh is currently writing up a study conducted on the interaction between pre-activation and activation solutions on steelhead sperm motility; we anticipate this work being submitted to Environmental Biology of Fishes soon. He is currently pursuing his D.V.M. at Washington State University. Josh Woolsey
