About the New Mexico Unit

The New Mexico Unit is led by Dr. Colleen Caldwell who began at the Unit in 1994 as the Assistant Unit Leader for Fisheries. Dr. James Cain, Assistant Unit Leader for Wildlife, is a wildlife biologist studying the ecology of large mammals in arid and semi-arid ecosystems. Drs. Caldwell and Cain are members of the Graduate College at New Mexico State University and as such hold research faculty rank. They teach graduate level courses and support graduate students and post-doctoral associates through research topics that range from native fish conservation to elk, bear, and desert bighorn sheep resource selection and population ecology.


The New Mexico Unit is housed within the Department of Fish, Wildlife and Conservation Ecology (FWCE) in the College of Agriculture and Consumer Sciences on the New Mexico State University campus in Las Cruces. Unit offices for both the scientists and students are located within FWCE of Knox Hall. The Unit scientists and affiliated staff oversee a suite of laboratories that include chemistry, GIS, and fisheries laboratories.
