Aposematism and mimicry in birds [PDF]
Ibis, 2021 We review the literature on warning coloration in birds starting from Alfred Russel Wallace's premise that aposematism may advertise difficulty in subduing prey rather than simply unpalatability. Across diverse taxa, there is a good deal of anecdotal information to suggest that signals, usually involving conspicuous coloration, are associated not only ...

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.

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 ...

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.

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 ...

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 ...
