Speciation with gene flow is greatly facilitated when traits subject to divergent selection also
contribute to non-random mating. Such traits have been called 'magic traits', which could be …

Ecology Letters (2011) 14: 591–602 Abstract The spectacular diversity in sexually selected
traits among animal taxa has inspired the hypothesis that divergent sexual selection can …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Throughout their lives animals must complete many tasks, including finding food, avoiding
predators, attracting mates, and navigating through a complex and dynamic environment …

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 …

Many animals are toxic or unpalatable and signal this to predators with warning signals
(aposematism). Aposematic appearance has long been a classical system to study predator …

Antipredator defenses and warning signals typically evolve in concert. However, the
extensive variation across taxa in both these components of predator deterrence and the …

Marine ecosystems are suffering severe depletion of apex predators worldwide [1–4]; shark
declines are principally due to conservative life-histories and fisheries overexploitation [5–8] …

Phenotypic and genetic divergence can be influenced by a variety of factors, including
sexual and natural selection, genetic drift and geographic isolation. Investigating the roles of …

It is commonly assumed that natural selection imposed by predators is the prevailing force
driving the evolution of aposematic traits. Here, we demonstrate that aposematic signals are …
