Florivory as an opportunity benefit of aposematism [PDF]
The American Naturalist, 2015 A.D.H. was supported by the European Research Council (Advanced Grant 250209 to A. Houston) and fellowships from the Wissenschaftskolleg zu Berlin and the Natural Environment Research Council (NE/L011921/1).Inconspicuous prey pay a cost of reduced ...

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,

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 ...

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

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

Aposematism and the Handicap Principle [PDF]
The American Naturalist, 2012 Aposematic prey use conspicuous warning signals to advertise their defenses to predators. It has long been recognized that the efficiency of a warning signal may be reduced if poorly defended prey (automimics) are present in the population. The handicap principle suggests that the use of warning signals by poorly defended prey may be kept in check if ...

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 ...
