High Contrast Markings Can Negate the Benefits of Transparent Camouflage
Ecology and EvolutionTransparency is, in theory, the ultimate form of concealment allowing for perfect background matching camouflage regardless of the environment. In nature, despite some remarkable examples of highly transparent organisms, physiological constraints mean ...

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.

Habitat Fragmentation in Urbanized Landscapes Favors Bird Species With Darker Plumage. [PDF]
Ecol EvolUsing long‐term breeding bird survey data from 30 remnant woodlot patches within a rapidly urbanizing landscape in southwest China, we demonstrate that species with darker plumage are more likely to persist in highly fragmented habitats. The pattern is slightly more pronounced in males than in females.

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 ...

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 ...

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 ...

Costs of colour change in fish: food intake and behavioural decisions [PDF]
, 2013 Many animals, particularly reptiles, amphibians, fish and cephalopods, have the ability to change their body colour, for functions including thermoregulation, signalling and predator avoidance.

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

Evolutionarily stable defence and signalling of that defence [PDF]
, 2006 We examine the evolution and maintenance of defence and conspicuousness in prey species using a game theoretic model. In contrast to previous works, predators can raise as well as lower their attack probabilities as a consequence of encountering ...
