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

open access: yesiScience, 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.

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

open access: yesJurnal 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.

Aposematism and the Handicap Principle [PDF]

open access: yesThe 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 ...

Phytochemical and Biological Study of Trophic Interaction between Pseudosphinx Tetrio L. Larvae and Allamanda Cathartica L.

open access: yesPlants, 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 ...

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

open access: yesEcol 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.

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

open access: yesMol 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,

Reliability in aposematic signaling [PDF]

open access: yesCommunicative & 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 ...

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

open access: yesEcology 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 ...

Bioluminescent aposematism in millipedes [PDF]

open access: yesCurrent 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

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

open access: yesEcology 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
