A Biogeography of Reptiles and Amphibians in the Gomez Farias Region, Tamaulipas, Mexico

Analyses the ecological distributions of reptiles and amphibians in southern Tamaulipas of northeastern Mexico. Observations are confined to a small, though topographically complex, section of the Sierra Madre Oriental to enable a more careful definition of zonal distribution than would be possible had the same amount of fieldwork been expended in a larger geographical unit.
