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 differences in habitat use by small mammals: evolutionary strategy or reproductive constraint?
TL;DR: Sexual differences in habitat do not appear to be an evolutionary strategy maximizing reproductive effort by females, or reducing predation, but these sexual differences may reduce intraspecific resource overlap, or may simply reflect reproductive constraints limiting female habitat use to suitable nesting areas.

TL;DR: It is found that all pairs of species at Soroa differ in at least one of the following niche axes: vegetation types occupied, substrates used, perch height, irradiance at occupied perch sites, and body temperature.

Optimal body size in lesser antillean anolis lizards -a mechanistic approach
TL;DR: Predicted optimal body sizes are close to the observed body sizes of Lesser Antillean anoles, and are relatively insensitive to both levels of prey activity and up to fourfold differences in prey density, while life expectancy and rates of field metabolism may influence predictions.

Bite‐force performance of the last rhynchocephalian (Lepidosauria: Sphenodon)
TL;DR: The role of bite force in the behavioural ecology of Sphenodon is discussed, it is proposed that the lower temporal bar, unique among extant lepidosaurs, does not necessarily constrain bite force, and possible effects of other morphological characteristics on bite‐force performance are evaluated.

Vive le difference! Sexual dimorphism and adaptive patterns in lizards of the genus Anolis.
TL;DR: It is concluded that the presence of ecologically-relevant dimorphism may in fact increase the adaptive diversity present within a community.

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.
