The Ecological Significance of Sexual Dimorphism in Size in the Lizard Anolis conspersus.
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

Sexual conflict mediated by ecological sex differences can generate diverse patterns of transgenerational plasticity
TL;DR: An individual-based model is used to investigate the evolution of TGP when the sexes experience different ecologies and finds that adaptive TGP rarely evolves when alleles at loci that determine offspring responses to environmental information originating from the mother and father are subject to sexually antagonistic selection.

TL;DR: The data indicate that Liolaemus occipitalis is a generalist, "sit-and-wait" or ambush predator as well as omnivorous, feeding on both arthropods and plant material.

Reproduction and sexual dichromatism in Sitana ponticeriana (Reptilia: Draconinae: Agamidae)
TL;DR: The results of a two-year study of the sexual dichromatism, breeding, clutch size and development in a population of Sitana ponticeriana, conducted at Balukhand-Konark Wildlife Sanctuary, Orissa, India show that eggs collected late in the reproductive season were significantly larger than those collected earlier.
