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

Absolute and Relative Secondary-Sexual Dimorphism in Wing Morphology: A Multivariate Test of the ‘Big Mother’ Hypothesis
TL;DR: Primary sexual size dimorphism in wing elements of Artibeus lituratus was examined and females were absolutely and relatively larger than males in many wing elements and exhibited no difference in morphological integration.

TL;DR: An analysis of temporal segregation by comparing night brightness with nocturnal activity of spotted and melanistic oncillas demonstrated the ecological significance of polymorphic colour patterns in this felid species.

Predator size and the suitability of a common prey
TL;DR: Toxomerus changes with spider mass from a large, hard-to-capture bonanza to a small, easy tocapture item of low per capita value, thereby compensating for its decline in per capitavalue.

The nematode community in the Atlantic rainforest lizard Enyalius perditus Jackson, from south-eastern Brazil.
TL;DR: This study presents data on the gastrointestinal parasite fauna of Enyalius perditus and their relationships with ecological aspects of hosts in a disturbed Atlantic rainforest area in the state of Minas Gerais, south-eastern Brazil.
(hymenoptera, aphelinidae): a case of intersexual resource partitioning?
TL;DR: It is possible that males, during their development, eliminate competitors, and this has been proposed as the selective advantage to male ectoparasitism, and a host shift at speciation could account for the divergence in host relationships of the sexes.
