The Nagler laboratory studies the effect of environmental factors, such as contaminants, photoperiod and diet on the reproductive biology of salmonid fishes.
My research training began with a BS degree, in Fish and Wildlife Biology, from the University of Guelph in 1983. This was followed with a MS degree from Concordia University in 1985, in which I investigated the sub-lethal reproductive toxicity of pentachlorophenol in female rainbow trout. I went on to study the physiology of ovarian development in a marine fish, the winter flounder, for my Ph.D. at Memorial University of Newfoundland in 1991. Subsequently, I worked as a research scientist on a variety of projects involving fish reproductive biology, in England and Canada, before joining the faculty at the University of Idaho.
