About this issue Abstract Phylogenetic analyses based on mitochondrial (mt) DNA have indicated that the cichlid species flock of the Lake Victoria region is derived from a single ancestral species ...

Mate preferences on male colour have been implicated in generating and maintaining species diversity among haplochromine cichlid fish. Their lek-like mating system suggests that not only male colour ...

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 ...

Evolutionary innovations help animals cross functional barriers and exploit new niches that were inaccessible to their ancestors. These might even promote rapid diversification or reduce extinction ...

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 ...

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 ...

Two new species of cichlid fish from Lake Victoria are described by biologists from Naturalis Biodiversity Center (Research Department Marine Zoology) and the Institute of Biology Leiden (Section ...

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 ...

ACCORDING to various natives from different places on the shore of the Victoria Nyanza, many of the lake fishes (all except the silurids, according to one fisherman) carry their fry in their mouths.

Some female fish have eyes for their man only. Colourful African cichlids have evolved into new species because females are partially blind to others. But even as that discovery is made, the species ...
