Jeffrey E Lovich, Ph.D.

As a Research Ecologist, Jeff is interested in the interactions of animals and their physical environment. Current research is focused on the ecology of turtles and tortoises and the effects of utility-scale renewable energy development (wind and solar) on wildlife, particularly in the Desert Southwest USA.

Research interests

Jeff has studied the ecology and systematics of turtles and other animals for over 30 years, discovering and naming four of the world’s 356 turtle species, including three in the United States and one in Japan. Other interests include the ecological impacts of invasive species, the ecology and distribution of relict species, and the impacts of human activities (including wind and solar energy development) on wildlife and ecological patterns and processes in the Mojave and Sonoran Deserts.
