The world in color presents a dazzling dimension of phenotypic variation. Biological interest
in this variation has burgeoned, due to both increased means for quantifying spectral …

Dramatic improvement of our understanding of the genetic basis of vision was brought by
the molecular characterization of the bovine rhodopsin gene and the human rhodopsin and …

Vertebrate vision is accomplished through light-sensitive photopigments consisting of an
opsin protein bound to a chromophore. In dim light, vertebrates generally rely on a single …

Throughout their lives animals must complete many tasks, including finding food, avoiding
predators, attracting mates, and navigating through a complex and dynamic environment …

The spectral absorption characteristics of the retinal photoreceptors of the blue tit (Parus
caeruleus) and blackbird (Turdus merula) were investigated using microspectrophotometry …

The deep sea is the largest habitat on earth. Its three great faunal environments–the twilight
mesopelagic zone, the dark bathypelagic zone and the vast flat expanses of the benthic …

Colour fascinates all of us, and scientists and philosophers have sought to understand the
true nature of colour vision for many years. In recent times, investigations into colour vision …

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

A very large proportion of the world's animal species are active in dim light, either under the
cover of night or in the depths of the sea. The worlds they see can be dim and extended, with …

In craniates, opsin‐based photopigments expressed in the eye encode molecular 'light
sensors' that constitute the initial protein in photoreception and the activation of the …
