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

Male and female Anolis carolinensis maintain their dimorphism despite the presence of novel interspecific competition.
TL;DR: In this paper, the authors test this prediction using a well-documented natural experiment generated by the recent arrival of Anolis sagrei to a set of small islands in Mosquito Lagoon, Florida, containing Anolis carolinensis.
An Experimental Study of Juvenile Competition and Habitat Niche Partitioning Between a Native Lizard ( Anolis carolinensis ) and an Introduced Congener ( Anolis sagrei ) in the Southeastern United States
TL;DR: I have examined the final electronic copy of this dissertation for form and content and recommend that it be accepted in partial fulfillment of the requirements for the degree of Doctor of Philosophy, with a major in Ecology and Evolutionary Biology.

Scaling Patterns and Ecological Correlates of Postcranial Skeletal Robusticity in Canis and Ursus: Implications for Human Evolution
TL;DR: Doyle et al. as mentioned in this paper investigated scaling patterns of the cross-sectional variables on limb length and joint surfaces for the interspecific and intraspecific samples of Canis and Ursus.

TL;DR: This paper used a multigeneration field experiment with brown anole lizards (Anolis sagrei) to test hypotheses about the predictability of evolution and found that evolutionary change at both phenotypic and genomic levels was difficult to forecast.
Niche dynamics of the felid guild following the Pleistocene Megafaunal Extinction
TL;DR: This paper applied ecological niche modeling to evaluate whether surviving felids filled in vacant niches post-extinction, and hypothesize that they ought to have shown increased niche-overlap patterns with mega-felids postextinction.

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.
