Body posture, gaze, and predator detection: how stalking behaviour may influence colour vision evolution

This study investigates how carnivore body posture and gaze influence predator detection by human observers with different color vision, finding that coat and facial color patterns affect detection success.

Detection of conspicuous and cryptic food by marmosets (Callithrix jacchus): An evaluation of the importance of color and shape cues

This study evaluates how color and shape cues influence food detection in marmosets, finding sex-specific differences in performance based on target color and camouflage.

The trade-off between color and size in lizards' conspicuous tails

This study tests if there is a trade-off between tail color and size in lizards, finding that larger red-tailed lizards are more likely to be attacked by birds, while color and size interactions influence predation rates.

The role of claw colouration in fiddler crabs' mate choice: Private communication channel or handicap?

This study investigates whether claw coloration in fiddler crabs functions as a private communication channel or a handicap, finding that UV-reflecting claws are preferred by females but also highly detectable by predators.

Influence of color and brightness on ontogenetic shelter preference by prawns (Macrobrachium rosenbergii)

This study evaluates how color and brightness preferences of prawns change with age, finding juveniles prefer blue and adults prefer dark gray shelters.
