Evolutionary History of Lake Tanganyika's Predatory Deepwater Cichlids
Hybridization among littoral cichlid species in Lake Tanganyika was inferred in several molecular phylogenetic studies. The phenomenon is generally attributed to the lake level-induced shoreline and habitat changes. These allow for allopatric divergence of geographically fragmented populations alternating with locally restricted secondary contact and introgression between incompletely isolated ...

متن کاملEvolutionary convergence of body shape and trophic morphology in cichlids from Lake Tanganyika
The cichlid species ̄ocks of the East African Great Lakes, Victoria, Malawi, and Tanganyika are unique examples of adaptive radiations (Greenwood, 1984). In each lake, highly specialized species that occupy a wide range of trophic niches are found, which are similar morphologically and behaviourally (Fryer & Iles, 1972). The similarities in trophic morphology between ®shes from different lakes c...
متن کاملA pharyngeal jaw evolutionary innovation facilitated extinction in Lake Victoria cichlids.
Evolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction. We present evidence that the modified pharyngeal jaws of cichlid fishes and several marine fish lineages, a classic example of evolutionary innovation, are not univ...

iv asymmetrically to selection. There was also a correlated response of body size. Furthermore, no evidence was found for the previously proposed sexual advertisement functions. All of this is inconsistent with the view that such trait is under strong directional sexual selection. It seems more likely that either non-adaptive processes currently shape the distribution of eggspot numbers or that...
