Ontogenetic shift from aposematism and gregariousness to crypsis in a Romaleid grasshopper - dataset

open access: yes, 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.

Beetles “in red”: are the endangered flat bark beetles Cucujus cinnaberinus and C. haematodes chemically protected? (Coleoptera: Cucujidae)

open access: yesThe European Zoological Journal, 2018
Two native species of the genus Cucujus show a wide geographic distribution in Europe, Cucujus cinnaberinus (Scopoli, 1763) and C. haematodes Erichson, 1845.

Variation of chemical compounds in wild Heliconiini reveals ecological factors involved in the evolution of chemical defenses in mimetic butterflies

open access: yesEcology and Evolution, 2020
Evolutionary convergence of color pattern in mimetic species is tightly linked with the evolution of chemical defenses. Yet, the evolutionary forces involved in natural variations of chemical defenses in aposematic species are still understudied. Herein,

Data from: Distance-dependent aposematism and camouflage in the cinnabar moth caterpillar (Tyria jacobaeae Erebidae)

open access: yes, 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 hypothesised to increase ...

A role for phenotypic plasticity in the evolution of aposematism [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2002
The evolution of warning coloration (aposematism) has been difficult to explain because rare conspicuous mutants should suffer a higher cost of discovery by predators relative to the cryptic majority, while at frequencies too low to facilitate predator aversion learning.

Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog

open access: yes, 2012
Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals.

Aposematism and crypsis in a rodent: antipredator defence of the Norwegian lemming

open access: yes, 2015
Aposematism is unusual in herbivorous mammals, and exceptions help clarify its ecology and evolution. The Norwegian lemming differs from other rodents in colouration and behaviour.

Colors and Some Morphological Traits as Defensive Mechanisms in Anurans

open access: yesInternational Journal of Zoology, 2009
Anurans may be brightly colored or completely cryptic. Generally, in the former situation, we are dealing with aposematism, and the latter is an example of camouflage.

The truth is in the detail: predators attack aposematic prey with less aggression than other prey types

open access: yes, 2020
Aposematic organisms are often unprofitable to predators (e.g. because of defensive chemicals) which they advertise with a conspicuous signal (e.g. bright and conspicuous colour signals).

The butterfly rash of lupus: An example of aposematism? [PDF]

open access: yesArthritis Research & Therapy, 2013
Even the most seasoned and savvy clinician views lupus warily, considering it one of the most bewildering diseases in all of medicine. This situation should not be a surprise since the manifestations of lupus are dizzying in their variety and exasperating in their subtlety.
