Animal camouflage has long been used to illustrate the power of natural selection, and
provides an excellent testbed for investigating the trade‐offs affecting the adaptive value of …

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 …

In nature, trickery and deception are widespread. Animals and plants mimic other objects or
species in the environment for protection, trick other species into rearing their young, lure …

The small, terrestrial eastern red-backed salamander is abundant on many forest floors of
northeastern North America. Dr. Robert Jaeger and many of his graduate students spent …

Many animals express unlearned colour preferences that depend on the context in which
signals are encountered. These colour biases may have evolved in response to the …

Multiple hypotheses have been proposed to explain the variation of dorsal patterns
observed in snakes, but no studies yet have tested them over broad taxonomic and …

Males of many species often use colourful and conspicuous ornaments to attract females.
Among these, male manakins (family: Pipridae) provide classic examples of sexual selection …

Warning colouration reduces predation risk by signalling or mimicking the unpleasantness
of prey and therefore increases survival. We tested in two experiments the evolutionary costs …

Increasingly, multiple selective factors are recognized as jointly contributing to the evolution
of morphology. What is not clear is how these forces vary across communities to promote …

Batesian mimicry is widespread, but whether and why different species of mimics vary
geographically in resemblance to their model is unclear. We characterized geographic …
