The evolution of crypsis when pigmentation is physiologically costly [PDF]
Animal Biodiversity and Conservation, 2020 Predation is one of the main selective forces in nature, frequently selecting for crypsis in prey. Visual crypsis usually implies the deposition of pigments in the integument. However, acquisition, synthesis, mobilisation and maintenance of pigments may

Common cuckoo females remove more conspicuous eggs during parasitism [PDF]
Royal Society Open Science, 2021 Avian obligate brood parasites gain an advantage by removing the eggs of the cuckoos who have already visited the nest, which can increase the chances of survival for their offspring.

Camouflage effects of various colour-marking morphs against different microhabitat backgrounds in a polymorphic pygmy grasshopper Tetrix japonica. [PDF]
PLoS ONE, 2010 Colour-marking polymorphism is widely distributed among cryptic species. To account for the adaptive significance of such polymorphisms, several hypotheses have been proposed to date.

Corn Snakes Can Behaviorally Enhance Crypsis by Choosing Complex Backgrounds and Substrate [PDF]
Animal Behavior and Cognition, 2020 Many organisms have evolved coloration that increases their likelihood of survival. Crypsis is one such mechanism employed by many animals to avoid detection by blending into their habitat.

Rapid Shifts in Visible Carolina Grasshopper (Dissosteira carolina) Coloration During Flights
Frontiers in Ecology and Evolution, 2022 Some brightly colored structures are only visible when organisms are moving, such as parts of wings that are only visible in flight. For example, the primarily brown Carolina grasshopper (Dissosteira carolina) has contrasting black-and-cream hindwings ...

Cuttlefish color change as an emerging proxy for ecotoxicology
Frontiers in Physiology, 2023 Lately, behavioral ecotoxicology has flourished because of increasing standardization of analyses of endpoints like movement. However, research tends to focus on a few model species, which limits possibilities of extrapolating and predicting ...

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

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.

Tests of search image and learning in the wild: Insights from sexual conflict in damselflies
Ecology and Evolution, 2021 Search image formation, a proximal mechanism to maintain genetic polymorphisms by negative frequency‐dependent selection, has rarely been tested under natural conditions.
