Brain organization and habitat complexity in Anolis lizards.
Across vertebrates, there is a broad correlation between neuroanatomy and the type of habitat preferred by a species. In general, species occupying habitats classified as more structurally complex have relatively larger brains and exaggerated structures related to navigating and exploiting those habitats. We empirically measured the structural habitat complexity of six species of Puerto Rican A...
متن کاملBrain evolution across the Puerto Rican anole radiation.
Patterns of brain evolution have been widely studied across vertebrates, with the bulk of studies using mammals and/or birds as model systems. Within these groups, species occupying different habitats have been shown to have divergent neuroanatomy, particularly with regard to differences in the relative size of different brain structures, correlated with differences in habitat complexity. We ex...
متن کاملEvolutionary approaches for studying functional morphology: examples from studies of performance capacity.
Performance studies have long been a cornerstone of evolutionary studies of adaptation because of their purported importance for fitness. Nevertheless, for most systems, the mechanistic link among habitat use, morphology and performance is poorly understood. Further, few studies consider how behavior affects the relationship between morphology and performance. Here, I highlight the utility of c...

متن کاملBehavioral convergence and adaptive radiation: effects of habitat use on territorial behavior in Anolis lizards.
Most studies of adaptive radiations focus on morphological aspects of differentiation, yet behavior is also an important component of evolutionary diversification, often mediating the relationship between animal ecology and morphology. In species within radiations that are convergent in ecology and morphology, we then also expect convergence in behavior. Here, we examined 13 Anolis lizard speci...
