The evolution of crypsis when pigmentation is physiologically costly
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

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 ...

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.

THE SELECTIVE ADVANTAGE OF CRYPSIS IN MICE [PDF]
Evolution, 2010 The light color of mice that inhabit the sandy dunes of Florida's coast have served as a textbook example of adaptation for nearly a century, despite the fact that the selective advantage of crypsis has never been directly tested or quantified in nature.

Camouflaging moving objects: crypsis and masquerade [PDF]
Behavioral Ecology, 2017 Motion is generally assumed to "break" camouflage. However, although camouflage cannot conceal a group of moving animals, it may impair a predator's ability to single one out for attack, even if that discrimination is not based on a color difference. Here, we use a computer-based task in which humans had to detect the odd one out among moving objects ...

Brazilian Journal of Biology, 2023 A little-studied characteristic of the Mexican native fish Dormitator latifrons is the effect that the color of the bottom or lining of ponds or tubs can have on their growth and blood parameters under controlled conditions.

Roosting ecology and the evolution of pelage markings in bats. [PDF]
PLoS ONE, 2011 Multiple lineages of bats have evolved striking facial and body pelage makings, including spots, stripes and countershading. Although researchers have hypothesized that these markings mainly evolved for crypsis, this idea has never been tested in a ...

Camouflage and Exploratory Avoidance of Newborn Cuttlefish under Warming and Acidification
Biology, 2022 Ocean warming and acidification have been shown to elicit deleterious effects on cephalopod mollusks, especially during early ontogeny, albeit effects on behavior remain largely unexplored.

Molecular crypsis by pathogenic fungi using human factor H. A numerical model.
PLoS ONE, 2019 Molecular mimicry is the formation of specific molecules by microbial pathogens to avoid recognition and attack by the immune system of the host. Several pathogenic Ascomycota and Zygomycota show such a behaviour by utilizing human complement factor H to

Post-attack aposematic display in prey facilitates predator avoidance learning
Frontiers in Ecology and Evolution, 2016 Warning signals protect unpalatable prey from predation because predators who learn the association between the warning signal and prey unprofitability decrease attacks on the prey.
