Aculeate Hymenopterans as Aposematic and Mimetic Models
Frontiers in Ecology and Evolution, 2022 Aposematism and mimicry are complex phenomena which have been studied extensively; however, much of our knowledge comes from just a few focal groups, especially butterflies.

Interspecific visual signalling in animals and plants: a functional classification [PDF]
, 2017 Organisms frequently gain advantages when they engage in signalling with individuals of other species. Here we provide a functionally structured framework of the great variety of interspecific visual signals seen in nature, then describe the different ...

Comparative transcriptomics of albino and warningly‐coloured caterpillars
Ecology and Evolution, 2021 Coloration is perhaps one of the most prominent adaptations for survival and reproduction of many taxa. Coloration is of particular importance for aposematic species, which rely on their coloring and patterning acting as a warning signal to deter ...

The evolution of warning signals as reliable indicators of prey defense [PDF]
, 2003 It is widely argued that defended prey have tended to evolve conspicuous traits because predators more readily learn to avoid defended prey when they are conspicuous.

Ecology and Evolution, 2021 Warning signals are often characterized by highly contrasting, distinctive, and memorable colors. Greater chromatic (hue) and achromatic (brightness) contrast have both been found to contribute to greater signal efficacy, making longwave colored signals (

The Evolutionarily Dynamics of Aposematism: a Numerical Analysis of Co-Evolution in Finite Populations [PDF]
, 2014 The majority of species are under predatory risk in their natural habitat and targeted by predators as part of the food web. During the evolution of ecosystems, manifold mechanisms have emerged to avoid predation.

Venom in Furs: Facial Masks as Aposematic Signals in a Venomous Mammal
Toxins, 2019 The function of colouration in animals includes concealment, communication and signaling, such as the use of aposematism as a warning signal. Aposematism is unusual in mammals, and exceptions help us to understand its ecology and evolution.

Poison Frog Colors Are Honest Signals Of Toxicity, Particularly For Bird Predators [PDF]
, 2012 Antipredator defenses and warning signals typically evolve in concert. However, the extensive variation across taxa in both these components of predator deterrence and the relationship between them are poorly understood.

Frontiers in Ecology and Evolution, 2022 Variation in aposematic signals was once predicted to be rare, yet in recent years it has become increasingly well documented. Despite increases in the frequency with which polytypism and polymorphism have been suggested to occur, population-wide ...

Social transmission of avoidance among predators facilitates the spread of novel prey [PDF]
, 2017 Warning signals are an effective defence strategy for aposematic prey, but only if they are recognized by potential predators. If predators must eat prey to associate novel warning signals with unpalatability, how can aposematic prey ever evolve?
