B chromosomes have a functional effect on sex determination in a species of cichlid fishes from Lake Victoria, according to a study by Japanese researchers. The researchers found sex-ratio distortions ...

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists from Tokyo ...

Biologists use the term adaptive radiation to describe a phenomenon in which new species rapidly evolve from an ancestral species, often in response to changes in the local environment that lead to ...

A once-threatened population of African fish is now providing a view of evolution in action. Laura Spinney asks what Lake Victoria cichlids have revealed about speciation. Ole Seehausen didn't expect ...

Evolutionary biologists are fascinated by how so many species of cichlid fishes have evolved in the Great Lakes of East Africa. It seems likely that visual cues played a key role in this explosive ...

B chromosomes have a functional effect on sex determination in a species of cichlid fishes from Lake Victoria, according to a study by Japanese researchers to be published in open-access journal PLoS ...

New genetic analyses of cichlids in Lake Victoria highlight several candidate genes that may drive adaptive radiation and provide evidence for decisive selective events that cause particular genetic ...
