Testing The Protective Function of Flash Coloration Using Wild Avian Predators

This study tests the flash coloration hypothesis using wild blue tits and digital prey models, finding no survival benefit from conspicuous hindwings during flight.

Unveiling key links between behaviour and appearance in the evolution of camouflage

This study shows that behavioral alignment with the background enhances camouflage in spiders by influencing shape, posture, and coloration through evolutionary algorithms.

Shining a light on camouflage evolution: using genetic algorithms to determine the effects of geometry and lighting on optimal camouflage

This study uses genetic algorithms to explore how lighting and habitat geometry influence optimal camouflage in prey, showing their combined effects on patterning and color.

Biologically inspired warning patterns deter birds from wind turbines

This study tests if biologically inspired warning patterns on wind turbine blades deter birds, finding that aposematic patterns significantly reduce approach behavior in great tits.

The effects of habitat structure and lighting on object and background appearance

The paper quantifies how lighting and 3D environment alter scene and object appearance, finding that blue-yellow contrast and pattern directionality are lighting-sensitive, while green-red information remains stable.
