▪ Abstract We review the physiological, molecular, and neural mechanisms of insect color
vision. Phylogenetic and molecular analyses reveal that the basic bauplan, UV-blue-green …

The use of video images in place of natural stimuli in animal behaviour experiments is
reviewed. Unlike most other artificial means of stimulus presentation, video stimuli can …

There is a bewildering diversity of signals, sensory systems, and signaling behavior. A
consideration of how these traits affect each other's evolution explains some of this diversity …

Cichlid fish species of Lake Victoria can interbreed without loss of fertility but are sexually
isolated by mate choice. Mate choice is determined on the basis of coloration, and strong …

Color patterns of natural populations of guppies (Poecilia reticulata) are a compromise
between sexual selection and predation avoidance. Field data on ambient light spectra …

Frequency-dependent predation may maintain or prevent colour pattern polymorphisms in
prey, and can be caused by a variety of biological phenomena, including perceptual …

In most animals, the origins of mating preferences are not clear. The 'sensory–bias'
hypothesis proposes that biases in female sensory or neural systems are important in …

Abstract; Different explanations of color vision favor different philosophical positions:
Computational vision is more compatible with objectivism (the color is in the object) …

All the information available to the brain for the interpretation of the visual scene comes from
the number of photons absorbed by a very limited number of photoreceptor types which are …
