Threat level and sound production mode modulate acoustic warnings and defensive biting in snakes

Functional Ecology, Volume 40, Issue 11, Page 3448-3459, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately assessing predation risk is important because it enables prey to match their defensive behaviours to the level of threat and avoid unnecessary investment in costly responses.

Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, Volume 2026, Issue 10, October 2026.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

The population genetics of crypsis in vertebrates: recent insights from mice, hares, and lizards [PDF]

, 2020
By combining well-established population genetic theory with high-throughput sequencing data from natural populations, major strides have recently been made in understanding how, why, and when vertebrate populations evolve crypsis.

Drought intensifies dominant competitor avoidance and risk‐dependent habitat selection in a large carnivore guild

Oikos, Volume 2026, Issue 10, October 2026.
Intraguild competition is a key force structuring predator communities, with dominant species impacting subordinate species' space use and access to resources. Climate change may intensify or reshape these processes, yet how climate conditions interact with dominance to influence predator space use and resource selection remains poorly understood.

Ineffective crypsis in a crab spider: a prey community perspective [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2009
Cryptic coloration is assumed to be beneficial to predators because of an increased encounter rate with unwary prey. This hypothesis is, however, very rarely, if ever, studied in the field. The aim of this study was to quantify the encounter rate and capture success of an ambush predator, in the field, as a function of its level of colour ...

Innate behaviours shape generalist herbivore host choice and feeding patterns independent of plant defences

Functional Ecology, Volume 40, Issue 10, Page 3243-3259, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–herbivore interactions are typically examined through plant defence and herbivore performance, yet individual herbivore behavioural mechanisms underlying these interactions are rarely considered alongside plant traits.

Selection of perching site background color by Hamadryas feronia (Lepidoptera: Nymphalidae) in Costa Rica: Implications for industrial melanism

Revista de Biología Tropical, 2012
Observations of the increased frequency of melanic forms in moths of the genus Biston in Great Britain after the industrial revolution lead to the development of the theory of industrial Melanism. Nonetheless, arguments against that interpretation of the

Sequence variation in the melanocortin-1 receptor (MC1R) pigmentation gene and its role in the cryptic coloration of two South American sand lizards

Genetics and Molecular Biology, 2012
In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the genetic basis of pigmentation is poorly known in this group.

High Contrast Markings Can Negate the Benefits of Transparent Camouflage

Ecology and Evolution
Transparency is, in theory, the ultimate form of concealment allowing for perfect background matching camouflage regardless of the environment. In nature, despite some remarkable examples of highly transparent organisms, physiological constraints mean ...
