Speciation through sensory drive in cichlid fish
TLDR
This work identifies the ecological and molecular basis of divergent evolution in the cichlid visual system, demonstrates associated divergence in male colouration and female preferences, and shows subsequent differentiation at neutral loci, indicating reproductive isolation.

A Second-Generation Genetic Linkage Map of Tilapia (Oreochromis spp.) Sequence data from this article have been deposited with the EMBL/GenBank data libraries under accession nos. G68180, G68324 and…
TLDR
This map will enable mapping and selective breeding of quantitative traits important to the economic culture of tilapia as a food fish and will contribute to the study of closely related cichlids that have undergone explosive adaptive radiation in the lakes of East Africa.

The genomic substrate for adaptive radiation in African cichlid fish
TLDR
It is concluded that a number of molecular mechanisms shaped East African cichlid genomes, and that amassing of standing variation during periods of relaxed purifying selection may have been important in facilitating subsequent evolutionary diversification.

The Eyes Have It: Regulatory and Structural Changes Both Underlie Cichlid Visual Pigment Diversity
Differential gene expression and coding sequence evolution play complementary roles in the adaptive diversification of cichlid sensory systems.

Evolution of the cichlid visual palette through ontogenetic subfunctionalization of the opsin gene arrays.
TLDR
Subfunctionalization through differential ontogenetic expression may be a key mechanism for preservation of opsin genes and provide a palette from which selection creates the diverse visual sensitivities found among the cichlid species of the lacustrine adaptive radiations.

Mix and Match Color Vision: Tuning Spectral Sensitivity by Differential Opsin Gene Expression in Lake Malawi Cichlids

Cone opsin genes of african cichlid fishes: tuning spectral sensitivity by differential gene expression.
TLDR
Variations in cichlid spectral sensitivity have arisen through evolution of gene regulation, rather than through changes in opsin amino acid sequence.

Adaptive molecular evolution in the opsin genes of rapidly speciating cichlid species.
TLDR
This study examines the evidence for differential adaptive molecular evolution in East African cichlid opsin genes due to gross differences in environmental light conditions and identifies a number of promising candidate-tuning sites for future study by site-directed mutagenesis.

Colour vision and speciation in Lake Victoria cichlids of the genus Pundamilia
TLDR
Variation in LWS λmax and in the proportion of red/red double cones could lead to differences in perceived brightness that may explain the evolution of variation in male coloration.

Cichlid fish visual systems: mechanisms of spectral tuning.
TLDR
Cichlids can also more finely tune visual pigments through alterations in opsin amino acid sequence, which could contribute to the evolution of cichlid diversity through speciation.
