Aposematism increases acoustic diversification and speciation in poison frogs [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 Multimodal signals facilitate communication with conspecifics during courtship, but they can also alert eavesdropper predators. Hence, signallers face two pressures: enticing partners to mate and avoiding detection by enemies.

Chemoecology, 2013
Discussions of aposematism traditionally have focused on the visual displays of prey that denote unpalatability or toxicity to predators. However, the construct of aposematism accommodates a spectrum of unprofitable traits signaled through various sensory modalities, including contact and distance chemoreception.

AbstractAposematism is the pairing of two kinds of defensive phenotype: an often repellent secondary defence that typically renders prey unprofitable to predators if they attack them and some evolved signal that indicates the presence of that defence.

Aposematism: Unpacking the Defences
Trends in Ecology & Evolution, 2019Aposematic coloration is commonly considered to signal unpalatability, yet animals advertise malodour, spines, and weaponry as well as toxins, some of which can be seen at a distance whereas others are hidden from predators. Separating defences into overt and covert categories in this way and whether they act before, during contact, or following ...

The evolution of aposematism is accompanied by increased diversification
Integrative Zoology, 2008AbstractAlthough the use of distinct colors to indicate unprofitability to predators (i.e. aposematism) is commonly thought of as an adaptation, our knowledge of its macroevolutionary effects is limited. Because aposematism is expected to decrease attacks by predators, we hypothesized that aposematic lineages should be larger on average than their non ...

Are aposematic signals honest? A review
Journal of Evolutionary Biology, 2015AbstractWe explore the relevance of honest signalling theory to the evolution of aposematism. We begin with a general consideration of models of signal stability, with a focus on the Zahavian costly signalling framework. Next, we review early models of signalling in the context of aposematism (some that are consistent and some inconsistent with costly ...

The Evolution of Aposematic Coloration
Oikos, 1981Recent work on the evolution of aposematic coloration highlights the need for clear distinctions to be drawn between both the processes involved and the selective forces operating. We define the term aposematic coloration, distinguish between the evolution of distastefulness and the evolution of aposematic coloration, and we consider the conditions ...

Parasitism as a potential driver of aposematism
Trends in Ecology & EvolutionAposematic animals couple unprofitability to predators, such as toxicity, with a warning signal, such as conspicuous coloration. Although toxicity and coloration can provide effective protection against predation, these traits also play a major role in the context of parasitism.
