Active background choice facilitates crypsis in a tropical crab
, 2017 Animals can evade predators in multiple ways, one of the most effective of which is to avoid detection in the first place. We know much about the evolution of color patterns that match the visual background to avoid detection (i.e., crypsis), yet we know

Shell color polymorphism in marine gastropods
Evolutionary Applications, 2023 Marine gastropods are characterized by an incredible variation in shell color. In this review, we aim to introduce researchers to previous studies of shell color polymorphism in this group of animals, trying to provide an overview of the topic and ...

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds
Ibis, EarlyView.Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.

Is eggshell pigmentation a condition-dependant strategy? Implications for egg crypsis in Japanese quail. [PDF]
, 2014 Avian eggshell colouration fulfills multiple adaptive functions, including egg camouflage. The potential role of the two main eggshell pigments in oxidative stress, biliverdin and protoporphyrin, may be behind a relationship between female ...

Frontiers in Ecology and Evolution, 2022 Variation in aposematic signals was once predicted to be rare, yet in recent years it has become increasingly well documented. Despite increases in the frequency with which polytypism and polymorphism have been suggested to occur, population-wide ...

Convergent mutations underpin the repeated evolution of brown plumage in seabirds
Ibis, EarlyView.Recent genetic data have provided crucial insights into the evolution of animal colour phenotypes, with the melanocortin‐1 receptor (MC1R) frequently implicated in dramatic colour shifts. However, the extent to which similar phenotypes are underpinned by convergent mutations at this locus remains unclear.

Crypsis influences escape decisions in the Round-tailed Horned Lizard (Phrynosoma modestum)
, 2010 Flight initiation distance (predator–prey distance when escape begins) increases as predation risk increases. Prey should have longer flight initiation distance when their background, movement, or current posture reduces crypsis.

Aposematic signaling and seasonal variation in dorsal pelage in a venomous mammal
Ecology and Evolution, 2021 In mammals, colouration patterns are often related to concealment, intraspecific communication, including aposematic signals, and physiological adaptations.

Physiological Entomology, EarlyView.The swallowtail butterfly Papilio machaon has a brown‐ and green‐coloured morph, with the brown being more common in the diapausing generation. The darker colouration of brown pupae did not confer advantages for thermoregulation when developing, but they did have lower diapause metabolic rates.

Assessing the Impact of Environment on the Color of Painted Turtles (Chrysemys picta) in the Wild
Ecology and EvolutionAnimal coloration is a complex phenotype that may be affected by genetics, evolution, ecology, and environment. Disentangling the impact of environment on phenotype can often be done in laboratory studies, but the results do not necessarily correspond to
