摘要

Reptiles make up a large component of the vertebrate ecosystem (Scaro et al., 1988), and some groups (i.e., lizards) have played an instrumental role in the development of community ecology (for review see Losos, 1994). However, in general, reptiles often have been overlooked as being important structural elements of biotic communities (Vitt, 1987; Scaro et al., 1988). For example, bio-mass production by lizards (Turner et al., 1976) and turtles (Iverson, 1982) may be equal or greater than that of birds or mammals in the same areas. In addition some snake species have been found to comprise over half of the food biomass delivered to nestling hawks (Grothe, 1992), and yet snakes as predators may consume a significant percentage of rodent populations (Diller and Johnson, 1988).
