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

Condition dependence in biosynthesized chemical defenses of an aposematic and mimetic Heliconius butterfly

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 ...

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 ...

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]

, 2015
During early development, many aposematic species have bright and conspicuous warning appearance, but have yet to acquire chemical defenses, a phenotypic state which presumably makes them vulnerable to predation.

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 ...

Joint effects of female preference intensity and frequency‐dependent predation on the polymorphism maintenance in aposematic sexual traits

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

The "Chameleon Ant" <i>Colobopsis imitans</i> Adapts Its Mimetic Appearance to Local Model Species Across the Mediterranean Basin (Hymenoptera: Formicidae). [PDF]

Ecol Evol
We collected morphometric data from Colobopsis samples across the Mediterranean Basin and the Caucasus, documented color patterns of these mimics and their local models, and performed unsupervised multivariate analyses. Morphometric data suggest a scenario where mimicry‐driven microevolutionary adaptations can produce significant phenotypic diversity ...

"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.

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 ...
