Unveiling the Defenses: A Current and Comprehensive Review of Coleoptera Carabidae Strategies [PDF]

open access: yesBiology
The Carabidae family, or ground beetles, is a wide and ecologically significant group within the Coleoptera order, known for its role as natural predators of agricultural pests and as bioindicators of ecosystem health.

Effect of odour on prey pattern aversion in jumping spidersEffect of odour on prey pattern aversion in jumping spiders [PDF]

open access: yesRoyal Society Open Science
Many animals defend themselves with toxic chemicals and use multimodal warning displays involving odours and bright colours to advertise their toxicity.

Spotted Patterns of Glass Frogs Can Disguise Imperfections in Transparency to Improve Camouflage [PDF]

open access: yesEcol Evol
Transparency could be considered the idealized version of camouflage, capable of producing remarkable background matching across heterogeneous microhabitats. However, although examples of highly transparent species indeed exist, transparency is often imperfect in execution, especially in terrestrial animal species.

EVOLUTIONARY PATHWAYS TO APOSEMATISM

open access: yes, 2016
The theory of aposematism as an adaptive explanation of conspicuous attributes in unprofitable prey is outlined before the selective conditions favouring aposematism are considered. Two componnets of aposematism, unprofitability and warning signal, are distinguished.

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 ...

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

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 ...
