Owing to their taxonomic, phenotypic, ecological and behavioural diversity and propensity
for explosive diversification, the assemblages of cichlid fish in the East African Great Lakes …

Visual opsin genes expressed in the rod and cone photoreceptor cells of the retina are core
components of the visual sensory system of vertebrates. Here, we provide an overview of the …

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 …

The jawless fish that were ancestral to all living vertebrates had four spectral cone types that
were probably served by chromatic-opponent retinal circuits. Subsequent evolution of …

As is true of virtually every realm of the biological sciences, our understanding of speciation
is increasingly informed by the genomic revolution of the past decade. Investigators can ask …

Among vertebrates, teleost eye diversity exceeds that found in all other groups. Their
spectral sensitivities range from ultraviolet to red, and the number of visual pigments varies …

Tuning the visual sensory system to the ambient light is essential for survival in many animal
species. This is often achieved through duplication, functional diversification, and/or …

The family Pomacentridae is a species-rich group of primarily marine fishes. The
phylogenetic relationships of the damselfishes are examined herein using sequence data …

The turbot is a flatfish (Pleuronectiformes) with increasing commercial value, which has
prompted active genomic research aimed at more efficient selection. Here we present the …

We studied the evolution of opsin genes in 59 ray-finned fish genomes. We identified the
opsin genes and adjacent genes (syntenies) in each genome. Then we inferred the changes …
