Chemical aposematism

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.

The “sexual selection hypothesis” for the origin of aposematism [PDF]

Evolution; International Journal of Organic Evolution
Abstract The evolution of aposematism, in which prey exhibit conspicuous signals indicating the presence of anti-predator defenses, is puzzling. Before predators learn to associate the signal with defense, increased visibility makes the conspicuous prey highly vulnerable to predation.

The complex business of survival by aposematism

Trends in Ecology & Evolution, 2005
The theory of warning signals dates back to Wallace but is still confusing, controversial and complex. Because predator avoidance of warningly coloured prey (aposematism) is based upon learning and reinforcement, it is difficult to understand how initially rare conspicuous forms subsequently become common.

Are aposematic signals honest? A review

Journal of Evolutionary Biology, 2015
AbstractWe 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 ...

Towards a historization of aposematism

Evolutionary Ecology, 2003
Aposematism is one of the oldest phenomena in evolutionary biology and still a major puzzle to biologists. Despite its evolutionary nature, most attempts to understand aposematism are devoid of phylogenetic components. In addition, most studies that do take phylogeny into account need to bring the analysis even further.

The Evolution of Aposematic Coloration

Oikos, 1981
Recent 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 & Evolution
Aposematic 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.

Aposematic design

Through aposematic design, I am breaking free from the belief that design should be minimalistic and neutral to appeal to a broader audience. I am beginning to create designs that reflect my own personal aesthetic and bluntness to better align with my work and to also voice my frustration.
