Genetic Structure of Pelagic and Littoral Cichlid Fishes from Lake Victoria
The approximately 700 species of cichlids found in Lake Victoria in East Africa are thought to have evolved over a short period of time, and they represent one of the largest known examples of adaptive radiation. To understand the processes that are driving this spectacular radiation, we must determine the present genetic structure of these species and elucidate how this structure relates to th...
متن کاملSimilar Levels of Diversity and Population Structure in Superflock and Non-superflock Cichlid Fishes from Lake Victoria, Africa
The haplochromine cichlids of the African Great Lakes have evolved into a spectacularly ecologically diverse 1 800 species. However, even within the same lake, not all cichlid lineages have radiated equally and many lineages have remained relatively species depauperate. Multiple biological factors particular to superflock species have been proposed, one of which is extreme environmental sensiti...
متن کاملComment on "Origin of the superflock of cichlid fishes from Lake Victoria, East Africa".
Based on an extensive mitochondrial haplotype analysis representing about 900 specimens, we developed a conclusive model for the origin and age of the Lake Victoria (LV) superflock of haplochromine cichlids (1). Our most important findings were that (i) the cichlids were initially derived from Lake Kivu (LK), which contains the genetically most diverse and oldest cichlid lineages of any of the ...
متن کاملOrigin of the superflock of cichlid fishes from Lake Victoria, East Africa.
Lake Victoria harbors a unique species-rich flock of more than 500 endemic haplochromine cichlid fishes. The origin, age, and mechanism of diversification of this extraordinary radiation are still debated. Geological evidence suggests that the lake dried out completely about 14,700 years ago. On the basis of phylogenetic analyses of almost 300 DNA sequences of the mitochondrial control region o...
متن کاملPopulation-structure and genetic diversity in a haplochromine fish cichlid of a satellite lake of Lake Victoria
The ∼ 500 species of the cichlid fish species flock of Lake Victoria, East Africa, have evolved in a record-setting 100 000 years and represent one of the largest adaptive radiations. We examined the population structure of the endangered cichlid species Xystichromis phytophagus from Lake Kanyaboli, a satellite lake to Lake Victoria in the Kenyan Yala wetlands. Two sets of molecular markers wer...
