High Contrast Markings Can Negate the Benefits of Transparent Camouflage
Ecology and Evolution, Volume 16, Issue 4, April 2026.Transparency is perhaps theoretically the most efficient means of achieving camouflage; however, in application, species show considerable variance in their degree of transparency. We demonstrate the fragility of transparent camouflage, detailing how imperfections reduce efficacy with implications in predation risk. ABSTRACT Transparency is, in theory,

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Optical Diversity and Nanostructural Organization in the Colored Scales of Sternotomis
Advanced Optical Materials, Volume 14, Issue 12, 25 March 2026.Vivid colors in Sternotomis beetles originate from nanoscale photonic architectures embedded within individual scales. Here, we provide a comparative optical and structural analysis of 57 scale types that reveal how ordered, quasi‐ordered, and disordered 3D networks tune color, saturation, and angular response.

Unripe red fruits may be aposematic [PDF]
Plant Signaling & Behavior, 2009 The unripe fruits of certain species are red. Some of these species disperse their seeds by wind (Nerium oleander, Anabasis articulata), others by adhering to animals with their spines (Emex spinosa) or prickles (Hedysarum spinosissimum). Certainly neither type uses red coloration as advertisement to attract the seed dispersing agents.

The golden mimicry complex uses a wide spectrum of defence to deter a community of predators
eLife, 2017 Mimicry complexes typically consist of multiple species that deter predators using similar anti-predatory signals. Mimics in these complexes are assumed to vary in their level of defence from highly defended through to moderately defended, or not ...

Predator Mixes and the Conspicuousness of Aposematic Signals [PDF]
The American Naturalist, 2004 Conspicuous warning signals of unprofitable prey are a defense against visually hunting predators. They work because predators learn to associate unprofitability with bright coloration and because strong signals are detectable and memorable. However, many species that can be considered defended are not very conspicuous; they have weak warning signals ...

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.

Restoration Ecology, Volume 34, Issue 3, March 2026.Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...

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 ...

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.
