Abstract
Stomach analysis of 47 S. jarrovi, an iguanid lizard from SE Arizona [USA], showed 512 prey items. Numbers and lengths of prey items were correlated with individual predator sizes. Lizards of all sizes ate equal numbers of prey items; males ate more than females. Larger lizards selected larger prey items and females selected larger items than males in the same size classes. The relevance to feeding theory strategy is discussed.This publication has 3 references indexed in Scilit:
