Research Professor of Biology
B. S., M. S., Cornell University
Ph.D. University of Michigan
Areas of Research: behavioral, population, and conservation ecology of birds, reptiles, and amphibians with a focus on long-term studies of birds, especially small owls, in urban areas, parks and wildlands in the southwestern U. S. and northern Latin America.
Current Teaching: thesis and dissertation advisement
I taught general biology, ecology, population ecology (graduate-level), and landscape evaluation and planning at Baylor, 1963-1995, became professor emeritus, and was reappointed research professor afterward. I have over 150 peer reviewed publications, faunal monographs, and book chapters plus books on (1) natural history of the U.S.-Mexican Borderlands, (2) lifestyles of suburban and rural Eastern Screech-Owls, and (3) suburban natural and unnatural history. I mostly study the interplay of native animals (especially birds, reptiles, and amphibians), human activities, and physical developments in the southwestern U.S., Mexico, and Central America. In doing research, I believe that modeling must be based on personal knowledge of basic natural history in an ecological-evolutionary context and be applicable to the conservation of nature.
