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.

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 ...

Reliability in aposematic signaling [PDF]
Communicative & Integrative Biology, 2010 In light of recent work, we will expand on the role and variability of aposematic signals. The focus of this review will be the concepts of reliability and honesty in aposematic signaling. We claim that reliable signaling can solve the problem of aposematic evolution, and that variability in reliability can shed light on the complexity of aposematic ...

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 (

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.

The application of temporal difference learning in optimal diet models [PDF]
, 2014 An experience-based aversive learning model of foraging behaviour in uncertain environments is presented. We use Q-learning as a model-free implementation of Temporal difference learning motivated by growing evidence for neural correlates in natural ...

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 ...

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 ...

Ecology and Evolution, 2022 Many aposematic species show variation in their color patterns even though selection by predators is expected to stabilize warning signals toward a common phenotype.
