Population Ecology And Reproductive Biology Of The Diamondback Watersnake, Nerodia Rhombifer (Serpentes: Colubridae), In Southernmost Texas, Ruben D. Zamora
Theses and Dissertations - UTB/UTPA
Nerodia rhombifer is a polytypic, semi-aquatic snake with a broad geographical distribution ranging from the American Midwest southward to Chiapas, Mexico. Although relatively abundant throughout much of its range, few ecological studies of the species have been conducted. This study provides basic population ecology information in a subtropical habitat. Population data were obtained in a mark-recapture study at Santa Ana National Wildlife Refuge, Hidalgo County, Texas, from August 1995 to December 1998. Specimens taken elsewhere in Hidalgo County provided information on the reproductive biology. This study provides the first absolute density estimates from anywhere within the species’ range. Quantitative information …

Revision Of The Ant Genus Crematogaster (Hymenoptera: Formicidae) In North America, Cynthia Ellen Morgan
Revision Of The Ant Genus Crematogaster (Hymenoptera: Formicidae) In North America, Cynthia Ellen Morgan
Open Access Theses & Dissertations
The natural history of thirty-eight species of the genus Crematogaster in North America has been discussed and distribution of specimens mapped. A dichotomous key to the workers of these species has been developed. I hypothesized that the species richness is not as great as previously thought in North America. A taxonomic review of these species has been made with the following changes:
Crematogaster cerasi Fitch 1855 senior synonym of C. browni Buren1968.
C. coarctata Mayr 1870 senior synonym of C. californica Emery 1895, C. mormonum
Emery 1895 and C. colei Buren1968.
C. depilis Wheeler 1919 senior synonym of C. larreae …
