Plants, 2023 In this article, we propose to explore the chemical interaction between Pseudosphinx tetrio L. and Allamanda cathartica L. using different analytical methods, including an innovative electrochemical approach (called electrochemical ecology) and ...

Ecology and Evolution, 2022 Aposematic animals advertise their toxicity or unpalatability with bright warning coloration. However, acquiring and maintaining chemical defenses can be energetically costly, and consequent associations with other important traits could shape chemical ...

Ontogenetic shift from aposematism and gregariousness to crypsis in a Romaleid grasshopper.
PLoS ONE, 2020 Traits of chemically-defended animals can change as an individual grows and matures, and both theoretical and empirical evidence favour a direction of change from crypsis to aposematism.

Body size but not warning signal luminance influences predation risk in recently metamorphosed poison frogs. [PDF]
, 2018 This is the final version of the article. Available from Wiley via the DOI in this record.During early development, many aposematic species have bright and conspicuous warning appearance, but have yet to acquire chemical defenses, a phenotypic state ...

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.

Ecology and Evolution, 2022 Maintenance of variation in aposematic traits within and among populations is paradoxical because aposematic species are normally under positive frequency‐dependent predation (PFD), which is expected to erode variation. Aposematic traits can evolve in an

Evolutionarily stable defence and signalling of that defence [PDF]
, 2006 We examine the evolution and maintenance of defence and conspicuousness in prey species using a game theoretic model. In contrast to previous works, predators can raise as well as lower their attack probabilities as a consequence of encountering ...

Bioluminescent aposematism in millipedes [PDF]
Current Biology, 2011 SummaryBioluminescence — the ability of organisms to emit light — has evolved about 40–50 times independently across the tree of life [1]. Many different functions for bioluminescence have been proposed, for example, mate recognition, prey attraction, camouflage, and warning coloration. Millipedes in the genus Motyxia produce a greenish-blue light at a

"Parasite-induced aposematism" protects entomopathogenic nematode parasites against invertebrate enemies [PDF]
, 2015 Aposematism is a well-known strategy in which prey defend themselves from predation by pairing defenses such as toxins, with warning signals that are often visually conspicuous color patterns.

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.
