Cognition contra camouflage: How the brain mediates predator-driven crypsis evolution [PDF]

, 2022
While crypsis is a prominent antipredator adaptation, the role of the brain in predator-driven evolution remains controversial. Resolving this controversy requires contextualizing the brain with established antipredator traits and predation pressure.

Colour change and colour phases in Lethrinidae with insights into ecology

Ecology and Evolution, 2023
Colour change is used by a wide range of animals. It is used for intra‐ and interspecific communication and crypsis, and can occur on morphological and physiological levels.

Morphological and Ontogenetic Skin Color Changes in the American Alligator (Alligator mississippiensis)

Animals, 2023
To assess skin color change in alligators, we maintained animals in differently lighted environments and also measured skin colors in an ontogenetic series of wild animals. Juvenile alligators maintained in black enclosures exhibited a gradual lightening

Camouflaged and Watchful: Stonefish Escape Behavior on Crowded Reefs

Journal of Marine Science and Engineering
Understanding escape behavior in cryptic and venomous reef fishes is critical for both ecological theory and public safety in coastal environments. We quantified the Flight Initiation Distance (FID) of 65 individual stonefish (Synanceia spp.) across four

Size, Spines, and Nests: What Drives Variation in Death‐Feigning Behavior in Fungus‐Farming Ants?

Integrative Zoology, EarlyView.
We investigated death‐feigning (DF; thanatosis) in fungus‐farming ants, testing how stimulus intensity, morphology, and nest traits shape its occurrence and duration using generalized linear mixed models. Stronger stimuli increased both likelihood and duration, but most variation was structured across species, colonies, and individuals.

Age and Appearance Shape Behavioral Responses of Phasmids in a Dynamic Environment

Frontiers in Ecology and Evolution, 2022
Although morphological adaptations leading to crypsis or mimicry have been studied extensively, their interaction with particular behaviors to avoid detection or recognition is understudied.

Dorsal Crypsis and Chemical Defense Jointly Shape Brain Size in Toads

Integrative Zoology, EarlyView.
We found that total brain size and dorsal crypsis under both ultraviolet‐sensitive (UVS) and violet‐sensitive (VS) tetrachromatic bird visual models were negatively associated across eight species of toads. Our findings suggest that when species reduce predation risk by evolving increased dorsal crypsis, they may exhibit decreased brain size due to ...

Data from: An ambusher’s arsenal: chemical crypsis in the puff adder (Bitis arietans)

, 2015
Ambush foragers use a hunting strategy that places them at risk of predation by both visual and olfaction-oriented predators. Resulting selective pressures have driven the evolution of impressive visual crypsis in many ambushing species, and may have led

Cryptic diversity highlights the challenge of Linnean and Wallacean shortfalls and the integral role of taxonomy in biodiversity conservation

Conservation Science and Practice, EarlyView.
Abstract Reliable and current taxonomic data are essential to conservation planning and prioritization. The use of genetic and genomic tools has revealed significant cryptic diversity across taxa and ecosystems, suggesting we are underestimating threatened biodiversity and using outdated species distributions.
