Island faunas can be characterized by gigantism in small animals and dwarfism in large
animals, but the extent to which this so-called 'island rule'provides a general explanation for …

Aim The island rule has been widely applied to a range of taxonomic groups, with some
studies reporting supporting evidence but others questioning this hypothesis. To bring more …

The Haţeg Island fauna of the terminal Late Cretaceous (ca. 71–65 million years ago) of
Romania is one of the most unusual dinosaur assemblages in the global fossil record. It has …

Aim Animal body sizes are often remarkably variable across islands, but despite much
research we still have a poor understanding of both the patterns and the drivers of body size …

Insular populations offer excellent opportunities to study the factors that influence
phenotypes. We observed island dwarfism in a widespread snake, the nose-horned viper …

Bergmann's Rule (ie, the tendency of body size to increase with decreasing environmental
temperature) was originally explained by a mechanism that is unique to endotherms …

While global patterns in body size evolution in island vertebrates have been described
extensively, the ecological processes that generate these patterns are not well understood …

Abstract Aim Bergmann's and Rapoport's rules are two ecogeographical patterns that predict
an increase in species body size and range size, respectively, with increasing latitudes …

We describe two diminutive species of rattlesnakes (genus Crotalus) from small nearshore
islands off the coast of Baja California in the western Gulf of California, Mexico. In order to …

Evolutionary theory predicts that in metapopulations subject to rapid extinction–
recolonization dynamics, natural selection should favour evolution of traits that enhance …
