The endemic cichlid fishes of Lakes Malawi, Tanganyika and Victoria are textbook examples of explosive speciation and adaptive radiation, and their study promises to yield important insights into these processes. Accurate estimates of species richness of lineages in these lakes, and elsewhere, will be a necessary prerequisite for a thorough comparative analysis of the intrinsic and extrinsic factors influencing rates of diversification. This review presents recent findings on the discoveries of… Expand
The species flocks of East African cichlid fishes: recent advances in molecular phylogenetics and population genetics
TLDR
Recent molecular data on population differentiation and phylogenetics are reviewed, which have helped to unravel, to some extent, the patterns and processes that led to the formation and ecological maintenance of cichlid species flocks. Expand
The mbuna cichlids of Lake Malawi: a model for rapid speciation and adaptive radiation
TLDR
There is no good evidence for monophyly in the mbuna, rather mitochondrial DNA phylogenies indicate that they are polyphlyetic with respect to benthic feeding cichlids of the genera Aulonocara, Alticorpus and some species of Lethrinops, and sexual selection acting on male colour seems the most plausible mechanism for initial species divergence.

The Adaptive Radiation of Cichlid Fish in Lake Tanganyika: A Morphological Perspective
TLDR
In the present review, morphological studies that relate to the adaptive radiation of Lake Tanganyika's cichlids are summarized and highlight their importance for understanding the process of adaptive radiation. Expand
Divergence and speciation of East African haplochromine cichlid fish
TLDR
It is demonstrated that signal and preference divergence among populations is not limited to patchily distributed Lacustrine endemics, but can also occur in the widely distributed riverine generalist lineage that is phylogenetically basal to the large lacustrine radiations, suggesting a role for divergence of secondary sexual traits in allopatry throughout adaptive radiation. Expand
The Lake Tanganyika cichlid species assemblage: recent advances in molecular phylogenetics
TLDR
An account of the taxonomy and phylogeny of the Lake Tanganyika cichlid species assemblage, its relationship to the African cichLid fauna, key factors leading to the astonishing diversity and recently proposed alternative age estimates are presented. Expand
Axes of differentiation in the bower‐building cichlids of Lake Malawi
TLDR
The phylogeny suggests that the forces of sexual and ecological selection are intertwined during the speciation of this group and that specific bower characteristics and trophic morphologies have evolved repeatedly, and that sand dweller species richness has been severely underestimated. Expand
Convergence and plasticity in the adaptive radiation of cichlid fishes
TLDR
The demonstration of plasticity in the cichlids’ pharyngeal jaw suggests it as a factor to be considered in answering the question of why there are so many cichLid species, and the revealed abundance of ecomorphological convergence without geographical or chronological separation indeed seems to defy Gause’s principle. Expand
Peripheral Isolate Speciation of a Lake Malawi Cichlid Fish from Shallow Muddy Habitats
TLDR
This study adds to the evidence that rapid evolution of novel phenotypes in peripheral habitats can add to the diversity of lacustrine cichlids through the evolution of at least partial reproductive isolation in allopatry. Expand
Genetic Structure of Pelagic and Littoral Cichlid Fishes from Lake Victoria
TLDR
The results suggest that initial groupings, some of which appear to have been related to habitat differences, as well as divergence between species within groups took place among the cichlid species of Lake Victoria. Expand
Evolution of Lake Malawi Cichlid Fishes (Perciformes: Teleostei)
TLDR
This work reviews theoretical studies and empirical research on the cichlid faunas of Africa to provide a synthetic overview of current knowledge of the evolutionary processes at work in the Cichlidae. Expand

Explosive speciation rates and unusual species richness in haplochromine cichlid fishes: Effects of sexual selection
TLDR
This chapter discusses possible explanations for disproportionally large species numbers in some cichlid fish lineages in East African Great Lakes and argues that sexual selection, if disruptive, can accelerate the pace of adaptive radiation because the resultant genetic population fragmentation allows a much increased rate of differential response to disruptive natural selection. Expand
Molecular systematics and radiation of the haplochromine cichlids (Teleostei: Perciformes) of Lake Malawi
TLDR
The mbuna group is generally thought to be a monophyletic assemblage, but results suggest that it is actually paraphy­ letic, and in contrast to the high morphological diversity among Malawi haplochro­ mine species, mtDNA sequence divergence was found to be remarkably low. Expand
Assortative mating among rock‐dwelling cichlid fishes supports high estimates of species richness from Lake Malawi
TLDR
All taxa showed high levels of allelic diversity providing evidence that genetic bottlenecking may have been of limited importance in the speciation process, and assortative mating among taxa differing only in male colouration is supportive of theories that speciation in these fishes has been driven by sexual selection by female choice.

A preliminary survey of the cichlid fishes of rocky habitats in Lake Malawi
Most aquarium fishes exported from Lake Malawi are cichlids of 10 rock-frequenting genera collectively referred to by their Chitonga name, Mbuna. These fishes provide a classical example ofExpand
Sympatric speciation suggested by monophyly of crater lake cichlids
TLDR
A mitochondrial DNA analysis of cichlid species flocks endemic to two such lakes in Cameroon suggests that the flocks in each lake are monophyletic: the implication being that each lake was colonized once only, the size and shape of each lake being such that subsequent diversification would have been sympatric. Expand
Mitochondrial phylogeography of rock-dwelling cichlid fishes reveals evolutionary influence of historical lake level fluctuations of Lake Tanganyika, Africa.
TLDR
The phylogeographic pattern of eretmodine cichlids suggests that major fluctuations in the level of the lake have been important in shaping their adaptive radiation and speciation, and the mitochondrially defined clades are in conflict with the current taxonomy of the group. Expand
Evaluating Biodiversity and Conserving Lake Malawi’s Cichlid Fish Fauna
TLDR
The results indicate that the genus level may be the appropriate taxonomic designation to consider for conservation purposes, and that areas of high generic endemism, such as the Muleri Islands, are significant for conservation. Expand
Local adaptations in populations of rock–dwelling haplochromines (Pisces:Cichlidae) from southern Lake Victoria
TLDR
It is investigated to what extent island populations of three species of the rock–dwelling genus Neochromis, endemic to Lake Victoria, are adapted anatomically to exploit locally abundant resources to find differences between two populations in the hyoid position and in the premaxilla that enhance suction feeding.

Genetic divergence, speciation and morphological stasis in a lineage of African cichlid fishes
TLDR
A case of surprisingly large genetic divergence among populations of the endemic Tropheus lineage of Lake Tanganyika, a lineage of six species that contains twice as much genetic variation as the entire morphologically highly diverse cichlid assemblage of Lake Malawi and six times more variation than the Lake Victoria species flock. Expand
Unusually fine–scale genetic structuring found in rapidly speciating Malawi cichlid fishes
TLDR
The results suggest that these fish populations are divided into thousands of subunits among which genetic divergence is currently occurring, and that this may provide unprecedented opportunities for allopatric speciation. Expand
