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

The structure of .:.4052 lizard communities
TL;DR: The structure of lizard communities in this somewhat loose sense of the word is focused on the niche relationships among such sympatric sets of lizard species, especially as they affect the numbers of species that coexist within lizard communities (species density).

DIETARY ANALYSIS OF THREE SPECIES OF THE GENUS Anolis (SAURIA: DACTYLOIDAE) IN “LOS TUXTLAS,” VERACRUZ, MEXICO
TL;DR: The stomach contents of 73 individuals from three species of the genus Anolis are analyzed to conclude that the three focal species show a generalist feeding behavior in times of abundant prey, such as the rainy season in which this study was conducted.

Sexual and natural selection interplay in sexual head shape dimorphism of two sympatric racerunners (Squamata: Lacertidae)
Tao Liang,Li Wang,Lei Shi +2 more
TL;DR: It is believed that both natural and sexual selection drive sexual head shape dimorphism in these two sympatric lizards, owing to high food resource competition in arid regions and head trait divergence can reduce competition by resulting in a preference for different prey types.

High-Density Geometric Morphometric Analysis of Intraspecific Cranial Integration in the Barred Grass Snake (Natrix helvetica) and Green Anole (Anolis carolinensis)
Sara M. Tharakan,NC Shepherd,David J. Gower,Edward L. Stanley,Ryan N. Felice,Anjali Goswami,Akinobu Watanabe +6 more
TL;DR: In this paper , the authors investigate the intraspecific patterns of cranial integration in two squamate species: Natrix helvetica and Anolis carolinensis, using the same high-density three-dimensional geometric morphometric approach used in a prior squamate-wide evolutionary study.

Ecological Distribution in Anoline Lizards of Puerto Rico
TL;DR: The eight species of the genus Anolis in Puerto Rico can be divided into four morphological similarities as discussed by the authors : perch height, perch diameter, high-shade preference and low-shading preference.
