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.

EVOLUTIONARY HISTORY OF THE PARROTFISHES: BIOGEOGRAPHY, ECOMORPHOLOGY, AND COMPARATIVE DIVERSITY
TLDR
A two-phase model of parrotfish evolution is presented to explain patterns of comparative diversity and an East Tethyan origin of the family and the recurrent evolution of excavating and scraping feeding modes is implied.

Evolutionary conservation of microsatellite flanking regions and their use in resolving the phylogeny of cichlid fishes (Pisces: Perciformes)
TLDR
The design of phylogenetically highly versatile MFR-primers will be of use not only for phylogeny reconstruction among families of perciform fishes, but also for population-level work in the thousands of species belonging to this highly species-rich suborder of fishes.

Directional selection has shaped the oral jaws of Lake Malawi cichlid fishes
TLDR
The results imply that the rapid and replicative nature of cichlid trophic evolution is the result of directional selection on chromosomal packages that encode functionally linked aspects of the craniofacial skeleton.

Integration and evolution of the cichlid mandible: the molecular basis of alternate feeding strategies.
TLDR
It is concluded that patterns of morphological integration of the cichlid jaw reflect a balance among conflicting functional demands and has the potential to alter mandibular morphology in a way that mimics adaptive variation among fish species.

The transcriptional consequences of mutation and natural selection in Caenorhabditis elegans
TLDR
This work directly compared observed transcriptional variation patterns in the mutation-accumulation and natural isolate lines to a neutral model of transcriptome evolution to show that strong stabilizing selection dominates the evolution of transcriptional change for thousands of C. elegans expressed sequences.

Reconstructing labroid evolution with single–copy nuclear DNA
TLDR
The data indicate that pharyngognathy has evolved independently among labroid families and that characters of the PJA are not reliable markers of perciform evolution, which ‘crushes’ conventional views of fish phylogeny and should engender novel concepts of piscine life history evolution.

Rapid isolation of CA microsatellites from the tilapia genome.
TLDR
The importance of minimizing the number of polymerase chain reaction (PCR) amplification cycles before and after the enrichment steps to reduce PCR recombination and the generation of chimaeric clones is demonstrated.
