Dietary Diversification and Specialisation in New World Bats Facilitated by Early Molecular Evolution

Dietary adaptation is a major feature of phenotypic and ecological diversification, yet the genetic basis of dietary shifts is poorly understood. Among mammals, Neotropical leaf-nosed bats (family Phyllostomidae) show unmatched diversity in diet; …

Molecular adaptation and convergent evolution of frugivory in Old World and neotropical fruit bats

Although cases of independent adaptation to the same dietary niche have been documented in mammalian ecology, the molecular correlates of such shifts are seldom known. Here, we used genomewide analyses of molecular evolution to examine two lineages …

Foraging shifts and visual preadaptation in ecologically diverse bats

Changes in behaviour may initiate shifts to new adaptive zones, with physical adap- tations for novel environments evolving later. While new mutations are commonly considered engines of adaptive change, sensory evolution enabling access to new …
