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.

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.

Are Toxic Butterflies More Easily Detected by Human 'Predators'? [PDF]
Ecol EvolAposematic signals are often thought to be conspicuous and stable across environments. Yet, butterflies can have distinct colours on their dorsal and ventral sides which contradict this prediction. We found that despite toxic butterflies having similar detectability on both sides, only dorsal detectability positively correlated with toxicity.

Sexual dimorphism in bite performance drives morphological variation in chameleons [PDF]
, 2014 Phenotypic performance in different environments is central to understanding the evolutionary and ecological processes that drive adaptive divergence and, ultimately, speciation.

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.

Colour change and assortment in the western rainbowfish [PDF]
, 2010 Grouping behaviour is widespread across the animal kingdom, and is known to reduce an individual's risk of predation, for example through predator confusion.

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
