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

Reproduction and Fat Body Cycle of Eurolophosaurus nanuzae (Sauria; Tropiduridae) from a Seasonal Montane Habitat of Southeastern Brazil
TL;DR: The effects of precipitation on the reproductive cycle of E. nanuzae could be related to the microclimatic conditions necessary for embryo development and hatchling survivorship, as well as to the greater food availability for hatchlings during the wet season.

TL;DR: It is shown that resource availability influences the degree of SSD among insular populations of Anolis sagrei lizards in the Bahamas and lends further support to the condition-dependent hypothesis, according to which the larger sex should display greater plasticity in growth in response to environmental conditions.

Beyond trophic morphology: stable isotopes reveal ubiquitous versatility in marine turtle trophic ecology
TL;DR: The idea that interspecific variation in trophic morphology among closely related species effectively permits resource partitioning has driven research on ecological radiation since Darwin first described variation in beak morphology among Geospiza.

TL;DR: In 15 of the 16 measurements, the males were significantly larger than the females (p in most of the dimensions measured, ranging from 4% (condyl breadth) to 10% (mandible height); the postorbital constriction was 2% narrower in the males.

Sexual dimorphism in traits related to locomotion: ontogenetic patterns of variation in Podarcis wall lizards
TL;DR: Patterns of sexual dimorphism of morphological traits relevant for locomotion in two lacertid lizards are investigated, aiming to identify ontogenetic sources of variation and shed light on the proximate causation of adult sexualDimorphism.

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.
