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

Habitat selection in Psammodromus algirus (Linnaeus, 1758) (Sauria: Lacertidae): age related differences
TL;DR: Habitat selection in adult and juvenile Psanimodromus algirus was studied along a Mediterranean successional gradient in southwestern Iberia; both age classes showed patterns of habitat selection which differed significantly from a random survey of the habitat.

Biogeography, Systematics, and Ecomorphology of Pacific Island Anoles
John G. Phillips,John G. Phillips,Sarah E. Burton,Sarah E. Burton,Margarita M. Womack,Evan Pulver,Kirsten E Nicholson +6 more
TL;DR: A phylogenetic analysis of anoles from these islands in light of the greater anole phylogeny finds that two species of solitary anoles (D. agassizi and N. townsendi) diverged from mainland ancestors prior to the emergence of their respective islands.

Nongeographic Morphologic Variation in the Mexican Vole (Microtus mexicanus)
Jennifer K. Frey,Dwight W. Moore +1 more
TL;DR: In this paper, the authors used multivariate and multivariate statistical analyses to assess variation in 23 external and cranial characters of Microtus mexicanus and found that adults and subadults of both sexes showed considerable overlap whereas juveniles were distinct.

Sexual dimorphism in size and shape among populations of the lizard Sceloporus variabilis (Squamata: Phrynosomatidae).
Raciel Cruz-Elizalde,Aurelio Ramírez-Bautista,Luis F. Rosas Pacheco,Abraham Lozano,Felipe de Jesús Rodríguez-Romero +4 more
TL;DR: The present study shows the importance of incorporating size and shape variables into analyses of sexual dimorphism among populations of a single species with a wide distribution, as well as the degree of difference among populations that inhabit different environments.

Sexual dimorphism in Trachylepis vittata (Olivier, 1804) (Sauria: Scincidae) in the Zagros Mountains, western Iran
TL;DR: The study showed the existence of slight sexual size dimorphism in body and head size between the sexes of the bridled skink, Trachylepis vittata, collected from western regions of the Iranian Plateau.
