Feeding specialisations are known to play an important role in the ecology and evolution of many organisms. In this study, we performed a comparative analysis based on the data of the gut content of eight species of the ...

Bergmann’s rule—the tendency for body size to increase in colder environments—remains controversial today, despite 150 years of research. Considerable debate has revolved around whether the rule applies within or among ...

The ecomorph concept of the adaptive radiation of Caribbean anoles is characterized by a suite of behavioral, ecological, and morphological traits that are tightly linked to microhabitat use in lizards. However, most studies ...

Islands are thought to facilitate adaptive radiation by providing release from competition and predation. Anole lizards are considered a classic example of this phenomenon: different ecological specialists ("ecomorphs") ...

Among the many Callinectes spp. across the western Atlantic, the blue crab C. sapidus has the broadest latitudinal distribution, encompassing both tropical and temperate climates. Its life history varies latitudinally, ...

Mountains are cradles for biodiversity and crucibles for climate-driven species loss, particularly for tropical ectotherms. Constriction on activity and amplified heat stress are two key sources of warming-driven vulnerability ...

Este texto analiza los trabajos de zoogeografía que se han realizado en islas, debiddo a su extensión y faunas limitadas y mayor probabilidad de separar los diversos factores que afectan la distribución de los animales. ...
