RESEARCH:

Dr. Middendorf's research focuses on reptilian and amphibian biology with emphases on behavior, ecology, evolution, and host-parasite interactions. He has published over 40 articles including papers on dealing with lizard resource partitioning, ecological responses to resource availability, defensive behaviors, and barriers to dispersal, as well as on biodiversity of a lowland amphibian community in Bolivia.  He is continuing his long-term studies of Sceloporus lizards in southeastern Arizona and of tropical herpetofaunal communities in Suriname. He has also been involved in examining environmental justice issues in urban areas, in implementing the Environmental Justice Section of the Ecological Society of America, and in developing interdisciplinary and environmental studies programs at Howard University. He  is a member of numerous scientific societies, including ASB, AIBS, ASIH, ESA, Herpetologists' League, SSAR, and Sigma Xi.
