James R. Dixon

James Ray Dixon (born 1928, in Houston, Texas; died January 10, 2015, in Bryan, Texas) was Professor Emeritus and Curator Emeritus of Amphibians and Reptiles at the Texas Cooperative Wildlife Collection at Texas A&M University. He lived in El Campo, Texas throughout most of his childhood. He published prolifically on the subject of herpetology in his distinguished career, authoring and co-authoring several books, book chapters, and numerous peer reviewed notes and articles, describing two new genera, and many new species, earning him a reputation as one of the most prominent herpetologists of his generation. His main research focus was morphology based systematics of amphibians and reptiles worldwide with emphasis on Texas, USA, Mexico, Central America, and South America, although bibliographies, conservation, ecology, life history and zoogeography have all been the subjects of his extensive publications.

Eponyms

A genus of lizards, Dixonius Bauer, Good & Branch, 1997, leaf-toed geckos from Southeast Asia, was named in his honor as well as several species of reptiles and amphibians, e.g., the white-lipped peeping frog, Eleutherodactylus dixoni Lynch, 1991 (= Eleutherodactylus albolabris); the gray checkered whiptail, Cnemidophorus dixoni Scudday, 1973 (= Aspidoscelis tesselata); Dixon's leaf-toed gecko, Phyllodactylus dixoni Rivero-Blanco & Lancini, 1968; and the large-eyed snake, Thamnodynastes dixoni Bailey and Thomas, 2007.[1]

Education and Early Career

Dixon attained his bachelor of science from Howard Payne University (1950), and then served in the Korean War (1951-1953). Upon returning from the war, he briefly acted as Curator of Reptiles at the Ross Allen Reptile Institute from 1954 to 1955. He earned his masters degree (1957) and PhD in (1961) from Texas A&M University. He was an Associate Professor of Veterinary Medicine at Texas A&M from 1959 until 1961.

Career

From 1961 until 1965 he was an Associate Professor of Wildlife Management at New Mexico State University and served as a consultant to the New Mexico state Game and Fisheries department. He was on the faculty of the University of Southern California and from 1965 until 1967 he was Curator of Herpetology at the Life Sciences Division at the Los Angeles County Museum in California. In 1967 he returned to Texas to become a professor at Texas A&M University, teaching Wildlife and Fisheries Science, and Curator of the Texas Cooperative Wildlife Collection or TCWC (recently renamed Biodiversity Research and Teaching Collections or BRTC). Over 20 herpetologist earned Ph.D.s studying under him at Texas A&M University. He has also served as President of several herpetological and naturalist societies including The Herpetologist League, Texas Herpetological Society, Texas Academy of Science; Society for the Study of Amphibians and Reptiles, Southwestern Association of Naturalists, and on the Board of Directors of the Texas Systems of Natural Laboratories. He has served on the faculty of Stephen F. Austin State University.
