Molecular phylogeny and taxonomic revision of the cichlid genus Hemichromis (Teleostei, Cichliformes, Cichlidae), with description of a new genus and revalidation of H. angolensis
The tribe Hemichromini is an early diverging, mainly Central and West African lineage within the species-rich African cichlid fishes (Cichliformes, Cichlidae) including two genera, Hemichromis Peters 1858 and the...

Open AccessOnly true pelagics mix: comparative phylogeography of deepwater bathybatine cichlids from Lake Tanganyika
In the absence of dispersal barriers, species with great dispersal ability are expected to show little, if at all, phylogeographic structure. The East African Great Lakes and their diverse fish faunas provide ...

Open AccessDelineating species along shifting shorelines: Tropheus (Teleostei, Cichlidae) from the southern subbasin of Lake Tanganyika
Species delineation is particularly challenging in taxa with substantial intra-specific variation. In systematic studies of fishes, meristics and linear measurements that describe shape are often used to delin...

Open AccessPhylogeny and phylogeography of Altolamprologus: ancient introgression and recent divergence in a rock-dwelling Lake Tanganyika cichlid genus
Stenotopic specialization to a fragmented habitat promotes the evolution of genetic structure. It is not yet clear whether small-scale population structure generally translates into large-scale intraspecific d...

Open AccessPast lake shore dynamics explain present pattern of unidirectional introgression across a habitat barrier
Introgression patterns between divergent lineages are often characterized by asymmetry in the direction and among-marker variation in the extent of gene flow, and therefore inform on the mechanisms involved in...

Open AccessA separate lowstand lake at the northern edge of Lake Tanganyika? Evidence from phylogeographic patterns in the cichlid genus Tropheus
In Lake Tanganyika, lake level fluctuations were shown to have had a major impact on the evolution of littoral species. Many species are subdivided into arrays of populations, geographical races and sister spe...

Open AccessBig fish, little divergence: phylogeography of Lake Tanganyika’s giant cichlid, Boulengerochromis microlepis
The largely endemic cichlid species flocks of the East African Great Lakes are among the prime examples for explosive speciation and adaptive radiation. Speciation rates differ among cichlid lineages, and the ...

A new species of Petrochromis (Perciformes: Cichlidae) from Lake Tanganyika
Based on morphological and molecular analyses of a Petrochromis fish (Cichlidae) from the southern end of Lake Tanganyika, this fish is considered a taxonomic species distinct from the six known congeners. A new ...

Open AccessConcordant female mate preferences in the cichlid fish Tropheus moorii
Discriminating female mate preferences enhance the variance in reproductive success among males of a population and create a potential for sexual selection, which can account for trait evolution and diversific...

Phylogenetic relationships of coral-associated gobies (Teleostei, Gobiidae) from the Red Sea based on mitochondrial DNA data
Bryaninops, Gobiodon, Paragobiodon and Pleurosicya are the most abundant genera of coral-associated gobies. These genera are adapted to live among coral, while other small reef gobies (e.g., the genus Eviota) sho...

Variation of territory size and defense behavior in breeding pairs of the endemic Lake Tanganyika cichlid fish Variabilichromis moorii
Lake Tanganyika harbors the ecologically, morphologically, and behaviorally most diverse species flock of cichlid fishes. It is comprised by substrate breeding and mouthbrooding species, most of which live in ...

The Lake Tanganyika cichlid species assemblage: recent advances in molecular phylogenetics
Lake Tanganyika is not the most species-rich of the Great East African Lakes, but comprises the greatest diversity of cichlid fishes in terms of morphology, ecology, and breeding styles. The lake contains a po...

Abundance, distribution, and territory areas of rock-dwelling Lake Tanganyika cichlid fish species
Lake Tanganyika, the second-oldest and second-deepest lake in the world, harbors an impressive cichlid fish fauna counting about 250 endemic species that are characterized by a great level of ecological, morph...

The impact of stocking on the genetic structure of European grayling Thymallus thymallus, Salmonidae) in two alpine rivers
The European grayling (Thymallus thymallus) is considered to be threatened in several European regions. In recent decades fishery managers have increasingly turned to stocking programs as one way to combat the ne...

Phylogeographic history of the genus Tropheus, a lineage of rock-dwelling cichlid fishes endemic to Lake Tanganyika
Lake Tanganyika contains the oldest and most complex flock of cichlid fishes counting about 200 endemic species. It is comprised of 16 ecologically, morphologically and genetically highly distinct tribes. Many...
