Antipredatory Strategies of Anurans: An Updated Conceptual Review

Ethology, Volume 132, Issue 9, Page 662-708, September 2026.
To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

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 ...

Limited influence of nest site vegetation on female wild turkey survival during incubation

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Resource quality in heterogeneous environments directly underlies individual fitness. Gallinaceous birds, such as female eastern wild turkeys (Meleagris gallopavo silvestris), face significant reproductive challenges, particularly predation risk associated with ground nesting.

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 ...

Defeating Crypsis: Detection and Learning of Camouflage Strategies

PLoS ONE, 2013
Camouflage is perhaps the most widespread defence against predators in nature and an active area of interdisciplinary research. Recent work has aimed to understand what camouflage types exist (e.g. background matching, disruptive, and distractive patterns) and their effectiveness.

Plastral Patterns Serve an Anti‐Predator Function in Freshwater Turtle Hatchlings

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Color and pattern serve as a range of anti‐predator defense mechanisms across taxa, from crypsis to warning coloration, and these phenomena are well described across invertebrate and vertebrate systems. Painted turtles (Chrysemys picta) are so named for their striking coloration and patterning.

Soft-tissue evidence for homeothermy and crypsis in a Jurassic ichthyosaur [PDF]

Nature, 2018
Ichthyosaurs are extinct marine reptiles that display a notable external similarity to modern toothed whales. Here we show that this resemblance is more than skin deep. We apply a multidisciplinary experimental approach to characterize the cellular and molecular composition of integumental tissues in an exceptionally preserved specimen of the Early ...
