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 ...

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.

The unresolved ecological and evolutionary role of fungal fruit body coloration
Frontiers in Ecology and Evolution, 2023 Fruit body-forming fungi are hyperdiverse and of central importance for the functioning of ecosystems worldwide. They provide habitat and resources for other organisms and perform critical roles in carbon and nutrient cycling. Like in animals and plants,

THE EVOLUTION OF APOSEMATISM IN MARINE GASTROPODS [PDF]
Evolution, 1991 In a recent review of the literature on marine gastropods, Rosenberg (1989) concludes that in this group,".. . as in the lepidopterans, . . . individual selection is the predominant mode of evolution of warning coloration." Rosenberg's analysis raises interesting issues concerning the evolution of aposematism generally, and in marine gastropods in ...

The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis [PDF]
Ecol EvolThis study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Conspicuousness and toxicity of Coccinellidae: An aposematic review [PDF]
Arthropods, 2020 Coccinellids (commonly known as ladybirds) mostly exhibit bright clouration and play a vital role in biological control of pests of important crops such as aphids and scale insects.

Multimodal Aposematic Defenses Through the Predation Sequence
Frontiers in Ecology and Evolution, 2021 Aposematic organisms warn predators of their unprofitability using a combination of defenses, including visual warning signals, startling sounds, noxious odors, or aversive tastes.

Signal honesty and predation risk among a closely related group of aposematic species. [PDF]
, 2015 This is the final version of the article. It first appeared from NPG via http://dx.doi.org/10.1038/srep11021Many animals have bright colours to warn predators that they have defences and are not worth attacking.

Distance-dependent aposematism and camouflage in the cinnabar moth caterpillar (Tyria jacobaeae, Erebidae) [PDF]
Royal Society Open Science, 2018 Defended prey often use distinctive, conspicuous, colours to advertise their unprofitability to potential predators (aposematism). These warning signals are frequently made up of salient, high contrast, stripes which have been hypothesized to increase ...

Signal verification can promote reliable signalling. [PDF]
, 2013 The central question in communication theory is whether communication is reliable, and if so, which mechanisms select for reliability. The primary approach in the past has been to attribute reliability to strategic costs associated with signalling as ...
