As well exemplified by a significant fraction of anole research, islands can act as natural laboratories of evolution. With limited space, fewer predators, simplified communities, and isolation from the mainland, islands often impose strong and distinctive selective pressures relative to continental habitats. However, although anoles provide some of the most famous examples of evolution on islands, insularity can exert its effects on different types of organisms.

Flight may affect the dispersal and evolution of birds. Using a new evolutionary tree, Claramunt et al. find that efficient fliers have broader geographic ranges, and speciation reduces range size, bu...

Abstract A pattern of allometry in which the degree of male-biased sexual size dimorphism (SSD) increases with species body size is known as “Rensch’s rule.” Over the past decades, a growing amount of...

What Rensch (really) found there Rensch’s rule is one of the great macroevolutionary patterns studied by evolutionary biologists. It describes the positive association between male-biased sex…

Abstract. Rensch’s Rule describes a pattern of interspecific allometry in which sexual size dimorphism (SSD) increases with size among closely related spec
