Evolutionary consequences of ecological release in Caribbean Anolis lizards
On the large islands of the Greater Antilles, multi-species communities oí Anolis lizards are composed of species specialized to use particular habitats; simUar sets of specialized species have evolved independently on each island. We studied species of anoles found on small Caribbean islands. Because these islands contain at most only one other species of anole, we predicted that species on th...
متن کاملA biomechanical analysis of intra- and interspecific scaling of jumping and morphology in Caribbean Anolis lizards.
Scaling models predict how functional variables change as animals grow or increase in size evolutionarily. However, few experimental studies have found support for the predictions of these models. Here, we use a force plate to investigate the scaling of functional variables associated with jumping within (for three species) and across adults of 12 species of Anolis lizards. Both ontogenetically...
متن کاملBrain 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 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 کاملThe quick and the dead: correlational selection on morphology, performance, and habitat use in island lizards.
Natural selection is an important driver of microevolution. Yet, despite significant theoretical debate, we still have a poor understanding of how selection operates on interacting traits (i.e., morphology, performance, habitat use). Locomotor performance is often assumed to impact survival because of its key role in foraging, predator escape, and social interactions, and shows strong links wit...
