Florivory as an Opportunity Benefit of Aposematism [PDF]

The American Naturalist, 2015
Inconspicuous prey pay a cost of reduced feeding opportunities. Flowers are highly nutritious but are positioned where prey would be apparent to predators and often contain toxins to reduce consumption. However, many herbivores are specialized to subvert these defenses by retaining toxins for their own use.

Quantifying the success of prey crypsis, aposematism, and evasiveness in avoiding predator attack. [PDF]

Ecology
Abstract Antipredator defenses typically act at distinct stages of the predation sequence—encounter, identification, approach, and subjugation. However, their effectiveness has rarely been quantified and compared simultaneously in wild predator–prey systems.

Skin Colour in Salamanders Is Modulated by Both Epitranscriptomic Methylation and Gene Expression. [PDF]

Mol Ecol
ABSTRACT Animal colouration is a key trait in organismal biology, being involved in natural and sexual selection, competition, and communication. Amphibians use their highly diverse colouration in many ecological interactions, but the molecular bases of their colour variation are less well understood than in other vertebrate systems. While the genetic,

The Coevolution of Colour Patterns and Hindwing Shapes on a Large Phylogenetic Scale Reveals Predation-Driven Adaptive Syndromes in Swallowtail Butterflies. [PDF]

Ecol Lett
By combining computer vision and morphometrics on museum specimens, we show that hindwing tail shape and colour patterns evolved in concert across swallowtails. Long‐tailed species display contrasted stripes and marginal spots, suggesting coevolution of deflective traits promoted by natural selection by predators.

Evolution of switchable aposematism: insights from individual-based simulations [PDF]

PeerJ, 2020
Some defended prey animals can switch on their normally hidden aposematic signals. This switching may occur in reaction to predators’ approach (pre-attack signals) or attack (post-attack signals). Switchable aposematism has been relatively poorly studied,

Coevolution of group-living and aposematism in caterpillars: warning colouration may facilitate the evolution from group-living to solitary habits

BMC Ecology and Evolution, 2021
Background Animals use diverse antipredator mechanisms, including visual signalling of aversive chemical defence (aposematism). However, the initial evolution of aposematism poses the problem that the first aposematic individuals are conspicuous to ...

Eocene aposematic patterns persist in modern European Lycidae beetles despite the absence of co-mimics

iScience, 2023
Summary: Ancient aposematic signals might have evolved under different ecological circumstances. Using European Cenozoic amber and phylogenetic reconstruction, we evaluated the evolution of net-winged beetle aposematism.

Aposematism facilitates the diversification of parental care strategies in poison frogs

Scientific Reports, 2021
Many organisms have evolved adaptations to increase the odds of survival of their offspring. Parental care has evolved several times in animals including ectotherms. In amphibians, ~ 10% of species exhibit parental care.

The polymorphism of vespid wasps (Hymenoptera: Vespidae) from Indonesia with morphology-based cladistic

Jurnal Entomologi Indonesia, 2023
Wasps in the family of Vespidae often have a yellowish black color with white or brown markings, but some species have variations in their markings and coloring.

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 ...
