TL;DR: It is suggested that habitat-use differences between sexes in ground-affiliated ecomorphs may drive the evolution of dorsal pattern dimorphism, and niche-associated diversification can generate phenotypic diversity within as well as among species.

TL;DR: The results show that species recognition evolved prior to sympatry in A. oculatus, and interspecific competition resulted in an increase in the time spent displaying and a divergence in the aggressive behavior of the native species toward conspecifics vs. heterospespecifics.

TL;DR: Size-adjusted head length of male and female lizards increased with population density, suggesting that larger heads might be advantageous when intraspecific competition is strong, and differences in morphology and injury frequency among islands for both males and females are detected, which suggests that agonistic competitive interactions among females may be stronger than previously appreciated.

TL;DR: It is read with deep concern of plans to drastically reduce the role of scientific research at one of the world's greatest museums of natural history, Chicago's Field Museum, and urged the Museum's authorities and supporters to find a way to prevent such a calamity.
