The Lake Victoria flock contains ten times less mtDNA variation than the Lake Malawi radiation, consistent with current estimates of the ages of the lakes. We present results of a phylogenetic ...

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 ...

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 ...

This is a preview. Log in through your library . Abstract Textbook examples of adaptive radiation often show rapid morphological changes in response to environmental perturbations. East Africa’s Lake ...

Pictured on the left is the Nile perch, a voracious predator introduced into Lake Victoria by humans to satisfy meat demands in the 1950s. On the right, several species of endemic cichlids that were ...

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 ...

Multiple cycles of lineage fusion by hybridization and diversification led to increasingly rapid and extensive radiations of cichlid fishes, including the explosive evolution of 500 Lake Victoria ...

AT FIRST, Ole Seehausen was overjoyed to find the small fish thrashing about in his net last spring. The blue-black cichlid with a saffron tail fin looked like one of the 200 species that biologists ...

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 ...
