Gene flow between species of Lake Victoria haplochromine fishes.
The haplochromine cichlid fishes of Lake Victoria (LV), East Africa, are a textbook example of adaptive radiation-a rapid divergence of multiple morphologically distinguishable forms from a few founding lineages. The forms are generally believed to constitute a "flock" of several hundred reproductively isolated species in a dozen or so genera. This belief has, until now, not been subjected to a...
متن کاملEvolution in fast forward: haplochromine fishes of the Lake Victoria region
The explosive speciation and adaptive radiation of haplochromine cichlid fishes in Lake Victoria is umivalled among vertebrates. It holds answers to many intriguing questions about the origins and maintenance of biological diversity. Unfortunately, Lake Victoria is also a case-study in anthropogenic mass extinction. Over 50 per cent of its endemic fishes disappeared between 1980 and 1986. Hundr...
متن کاملPhylogeography of Haplochromine Fish in the Lake Victoria Region
again somewhere and celebrate our traditional barbecue on the roof !!! Johannes set foot on the shores of the Great East African Lakes. Luckily, Darwin stumbled over some remote Islands in the Pacific Ocean instead and found some finches there, and later wrote his famous books. I think we are very lucky that we have something like an Evolutionary Theory today. For if Darwin had seen the splendi...
متن کاملTwo new species of zooplanktivorous haplochromine cichlids from Lake Victoria, Tanzania
Two new species of zooplanktivorous haplochromine cichlids from Lake Victoria, Tanzania, are described and illustrated. These species closely resemble each other. Their affinities to other zooplanktivorous haplochromines from Lake Victoria are discussed. Haplochromis argens sp. n., which featured under nicknames (mainly Haplochromis "argens") in more than 50 papers, was caught both in the Mwanz...
متن کاملPleistocene desiccation in East Africa bottlenecked but did not extirpate the adaptive radiation of Lake Victoria haplochromine cichlid fishes.
The Great Lakes region of East Africa, including Lake Victoria, is the center of diversity of the mega-diverse cichlid fishes (Perciformes: Teleostei). Paleolimnological evidence indicates dramatic desiccation of this lake ca. 18,000-15,000 years ago. Consequently, the hundreds of extant endemic haplochromine species in the lake must have either evolved since then or refugia must have existed, ...
