Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

We review the use of clay models to explore questions about predation rates on small
vertebrate taxa that are typically difficult to observe directly. The use of models has a …

Poison dart frogs provide classic examples of warning signals: potent toxins signaled by
distinctive, conspicuous coloration. We show that, counterintuitively, the bright yellow and …

Aposematic organisms couple conspicuous warning signals with a secondary defense to
deter predators from attacking. Novel signals of aposematic prey are expected to be …

Mimicry is one of the best-studied examples of adaptation, and recent studies have provided
new insights into the role of mimicry in speciation and diversification. Classical Müllerian …

Background Many intriguing questions about predator-prey interactions can be addressed
by using clay models of prey animals. These are placed in the field to test predators' …

Warning signals are predicted to develop signal monomorphism via positive frequency‐
dependent selection (+ FDS) albeit many aposematic systems exhibit signal polymorphism …

Natural selection is widely noted to drive divergence of phenotypic traits. Predation pressure
can facilitate morphological divergence, for example the evolution of both cryptic and …

Optimal camouflage can, in principle, be relatively easily achieved in simple, homogeneous,
environments where backgrounds always have the same colour, brightness and patterning …

While divergent ecological adaptation can drive speciation, understanding the factors that
facilitate or constrain this process remains a major goal in speciation research. Here, we …
