Ultrasound and ultraviolet: crypsis in gliding mammals [PDF]
PeerJGliding is only present in six extant groups of mammals—interestingly, despite divergent evolutionary histories, all mammalian gliders are strictly nocturnal.

Oriental reed warblers retain strong egg recognition abilities during the nestling stage [PDF]
Ecology and EvolutionEgg recognition and rejection are the most common and effective anti‐parasitic strategies against avian brood parasitism in terms of maintaining stability over time and plasticity in response to environmental cues.

Role of body size and shape in animal camouflage [PDF]
Ecology and EvolutionAnimal camouflage serves a dual purpose in that it enhances both predation efficiency and anti‐predation strategies, such as background matching, disruptive coloration, countershading, and masquerade, for predators and prey, respectively.

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.

Environmental Factors and Co-Occurrence Patterns Influence Dorsal Brightness in Two Jumping Mice Species in the Western United States. [PDF]
Ecol EvolWe examined how dorsal coloration varies in the endangered New Mexico jumping mouse (Zapus luteus) and its close relative, the western jumping mouse (Z. princeps) in relation to environmental variables and co‐occurence patterns using standardized photographs of museum specimens.

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.

Bolletino di zoologia, 1992 Abstract To estimate the matching between the backs of adult Talitrus saltator and the sand from their home beaches, reflectance, and patch shape and size were measured. Results show that in general there is a good matching between sandhopper back patterns and the local sand. Captivity caused a significant difference in the degree of similarity between
