Cryptic Ontogenetic Changes in the Ventral Coloration of a Color Polymorphic Wall Lizard (Podarcis muralis)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 1, Page 39-57, January 2026.
Wall lizards' ventral coloration undergoes cryptic ontogenetic color changes invisible without UV vision. We tracked wall lizards from hatching to one year of age. Spectrophotometry and visual modeling reveal that juveniles show a distinct UV‐enhanced white coloration that changes differently across sexes and body regions.

Predator dependent mimetic complexes: Do passerine birds avoid Central European red-and-black Heteroptera?

European Journal of Entomology, 2010
True bugs are generally considered to be well protected against bird predation. Sympatric species that have similar warning coloration are supposed to form a functional Müllerian mimetic complex avoided by visually oriented avian predators.

Brown dog tick, Rhipicephalus sanguineus sensu lato, infestation of susceptible dog hosts is reduced by slow release of semiochemicals from a less susceptible host [PDF]

, 2017
Domestic dog breeds are hosts for the brown dog tick, Rhipicephalus sanguineus sensu lato, but infestation levels vary among breeds. Beagles are less susceptible to tick infestations than English cocker spaniels due to enhanced production of 2-hexanone ...

Endless forms most hidden: katydids that masquerade as moss [PDF]

, 2017
In the cloud forests of the central range of the Colombian Andes, we discovered a species of katydid (Orthoptera: Tettigoniidae) that imitates mosses to an uncanny degree and is exceedingly difficult to detect. The camouflage exhibited by this particular

Maternal effects and the evolution of aposematic signals [PDF]

Proceedings of the National Academy of Sciences, 2001
Aposematic signals that warn predators of the noxious qualities of prey gain their greatest selective advantage when predators have already experienced similar signals. Existing theory explains how such signals can spread through selective advantage after they are present at some critical frequency, but is unclear about how warning signals can be ...

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.

Systematic Review of the Ethiopian Apparel Industry’s Historical Development and Current Insights

Journal of Engineering, Volume 2026, Issue 1, 2026.
This review systematically maps the literature on the transformation of the Ethiopian garment industry over 30 years (from 1995 to 2025). The main objective is to plot and evaluate how academic research has described the transition of the sector, previously a craft‐based heritage cottage industry where, for instance, traditional attire such as the ...

Body Size Is Positively Correlated With Conspicuous Coloration in Ambystoma Salamanders, but Negatively Correlated With Conspicuous Coloration in Plethodon Salamanders

Frontiers in Ecology and Evolution, 2018
Conspicuous coloration coupled with secondary defensive mechanisms is known as aposematic coloration and is used in predator avoidance and defense. Classic theory argues that aposematic signals tend to be more effective in larger organisms as they are ...

A bee or not a bee: an experimental test of acoustic mimicry by hoverflies [PDF]

, 2016
The degree of similarity between Batesian mimics and their models varies widely and occurs across a range of sensory modalities. We use three complementary experimental paradigms to investigate acoustic mimicry in hoverflies (Diptera: Syrphidae) which ...
