Despite the impressive growth of knowledge on the phylogenetic systematics of dart-poison
frogs and their relatives (Dendrobatoidea) over the past decade, many problems remain to …

Despite rising interest among scientists for over two centuries, parental care behavior has

Biotic interactions are widely accepted as an important driver of ecological and evolutionary
patterns, contributing to the structure of systems as diverse as tropical tree seedlings …

Amphibians present pharmacologically active aliphatic, aromatic and heterocyclic molecules
in their skin as defense against microorganisms, predators and infections, such as steroids …

The selective advantage of chemical defenses is evident by its occurrence in many groups
of organisms. Toxic and unpalatable substances are often employed by organisms to avoid …

We sequenced the genome of the strawberry poison frog, Oophaga pumilio, at a depth of
127.5× using variable insert size libraries. The total genome size is estimated to be 6.76 Gb …

Many animals have bright colours to warn predators that they have defences and are not
worth attacking. However, it remains unclear whether the strength of warning colours reliably …

Multimodal signals facilitate communication with conspecifics during courtship, but they can
also alert eavesdropper predators. Hence, signallers face two pressures: enticing partners to …
