Similarly, exposure of male garter snakes (Thamnophis sirtalis) to females of different sizes causes them to alter their courtship criteria (Shine et al., 2006).
Five of these, i.e., common kingsnake (Lampropeltis getula), eastern racer (Coluber constrictor), eastern rat snake (Elaphe obsoleta), western ribbon snake (Thamnophis proximus) and copperhead (Agkistrodon contortrix), are considered to be generalists in their habitat and/or their prey preferences (Conant & Collins 1998).
cadaverina) and several mesophilic reptiles (e.g., two-striped garter snake Thamnophis hammondii, California striped racer Masticophis lateralis) that are fairly widespread in the Californian Province, have widely fragmented distributions associated with palm oases to the south in the central peninsula (Grismer, 2002).

Three species, the western cottonmouth (Agkistrodon piscivorus leucostoma), the eastern yellow-bellied racer (Coluber constrictor flaviventris) and the Texas garter snake (Thamnophis sirtalis annectans), accounted for 58% of all individuals captured.
