TLDR
Anolis conspersus selects prey from a wide range of taxa and shows no obvious intraspecific specialization not connected to differences in microhabitat and prey size.Abstract:
Adult males of Anolis conspersus capture prey of significantly larger size and occupy perches of significantly greater diameter and height than do adult females; similarly, these three dimensions of the niche are significantly larger for adult females than for juveniles. Adult males on the average eat a smaller number of prey, and the range in size of prey is larger. The relationship between the average length of the prey and that of the predator is linear when the predator size is above 36 millimeters, but becomes asymptotic when it is below that value. Subadult males as long as adult females eat significantly larger food than do the latter, but only in the larger lizards is this correlated with a relatively larger head. Anolis conspersus selects prey from a wide range of taxa and shows no obvious intraspecific specialization not connected to differences in microhabitat and prey size. The efficiency of this system for solitary species is pointed out.read more

An analysis of prey consumed by the anuran leptodactylus fallax from dominica west indies
TL;DR: The prey consumed by Leptodactylus fallax were analyzed in regard to sex, body size, season of capture, prey weight, and prey length, and there was no appreciable difference between sexes in the mean length and mean number of prey items per frog.

Morphometric and genetic divergence in island and mainland populations of Anolis nebulosus (Squamata: Polychrotidae) from Jalisco (Mexico): an instance of insular gigantism
TL;DR: The morphological characteristics of the anoles on Don Panchito match with the expectation of the so-called “reversed island syndrome” theory, which predicts an increased body size and sexual dimorphism in lizards living on very small islands characterized by unpredictable environmental conditions.

07. Feeding ecology of Ameiva ameiva in a caatinga area of northeastern Brazil
TL;DR: Despite differences between adult and juvenile lizards in maximum and average prey sizes, the fact that adults continue to feed on small prey suggests that there may be competition for food resources between age classes.

Free-loaders, free-lancers and bushwhackers: sexual dimorphism and seasonal changes in prey-capture behavior of ambush bugs.
TL;DR: Sexual dimorphism in the feeding behavior of the ambush bug Phymata americana Melin is closely tied to differences in sexual role and the evidence is the way males and females grasp prey on which they feed.
