Ecology and Evolution, 2023 Camouflage is a common trait enabling animals to avoid detection by predators and prey. Patterns such as spots and stripes are convergent across carnivore families, including felids, and are hypothesized to have adaptive value through camouflage.

Lizard colour plasticity tracks background seasonal changes
Biology Open, 2020 Environmental heterogeneity on a spatial and temporal scale fosters an organism's capacity to plastically alter coloration. Predation risk might favour the evolution of phenotypic plasticity in colour patterns, as individuals who change colour throughout

Crypsis via leg clustering: twig masquerading in a spider [PDF]
Royal Society Open Science, 2015 The role of background matching in camouflage has been extensively studied. However, contour modification has received far less attention, especially in twig-mimicking species.

Crypsis in the Pelagic Environment [PDF]
American Zoologist, 1990 Pelagic aquatic environments differ from terrestrial environments in being three-dimensional and relatively homogeneous, rather than two-dimensional and heterogeneous. The present paper examines the causes and consequences of these differences in the context of their influence on the interactions of animals with environmental light. Particular emphasis

Changeable camouflage: how well can flounder resemble the colour and spatial scale of substrates in their natural habitats? [PDF]
Royal Society Open Science, 2017 Flounder change colour and pattern for camouflage. We used a spectrometer to measure reflectance spectra and a digital camera to capture body patterns of two flounder species camouflaged on four natural backgrounds of different spatial scale (sand, small

THE ORIGIN OF POLYMORPHIC CRYPSIS IN A HETEROGENEOUS ENVIRONMENT [PDF]
Evolution, 2010 Polymorphic crypsis has been observed in several taxa, but has, until now, lacked a firm theoretical understanding. How does a single morph, well camouflaged in one type of habitat, evolve crypsis in another, not isolated, habitat? We here analyze a model of one prey species living in two different habitats connected by passive dispersal.

Ecology and Evolution, 2020 Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration‐matching and disruptive coloration.

Ecology and Evolution, 2020 In heterogeneous habitats, camouflage via background matching can be challenging because visual characteristics can vary dramatically across small spatial scales.

Ecosphere, 2022 Although consumptive effects of predators have long been central to ecology, predation‐risk effects have emerged as major components of predator–prey interactions. Both consumptive and predation‐risk effects should vary with predator functional traits (e.

Colour change and colour phases in Lethrinidae with insights into ecology
Ecology and Evolution, 2023 Colour change is used by a wide range of animals. It is used for intra‐ and interspecific communication and crypsis, and can occur on morphological and physiological levels.
