Evolution in ancient lakes: radiation of Tanganyikan atyid prawns and speciation of pelagic cichlid fishes in Lake Malawi

  title={Evolution in ancient lakes: radiation of Tanganyikan atyid prawns and speciation of pelagic cichlid fishes in Lake Malawi},
  author={G. Fryer},
Atyid prawns from Lake Tanganyika are still poorly understood. There are at least 11 species sharing an exceptionally small size and a reduction in the number of branchiae. The majority are benthic although some are pelagic. This is reflected in different morphologies of the body and walking legs. Morphological adaptions of the denticles on the chelipeds are adaptive as they relate to different ways of feeding. Pelagic fish from Lake Malawi do not represent an example of sympatric speciation as… Expand

Uncharted digenean diversity in Lake Tanganyika: cryptogonimids (Digenea: Cryptogonimidae) infecting endemic lates perches (Actinopterygii: Latidae)
The present study provides the first comprehensive characterisation of the digenean diversity in a fish family from Lake Tanganyika which will serve as a baseline for future explorations of the lake’s digenesan fauna. Expand


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

Six species of atyid prawns, representing five genera, occur in streams on the West Indian island of Dominica (figures 1-6). The ecology and habits of each are described and the relation of featuresExpand
Genetic population structure indicates sympatric speciation of Lake Malawi pelagic cichlids
Mitochondrial DNA sequence data from 90 species, representing all major clades within the Lake Malawi flock, indicate reciprocal monophyly of the pelagic clade, suggesting that speciation in sympatry is more plausible (and widespread) within the cichlid species flocks than previously thought.

Abundance and Micro-Distribution of Cichlid Fishes on a Rocky Shore of Lake Tanganyika
Every species of rock dwelling cichlid fishes were counted with help of SCUBA at Luhanga in the northwestern part of Lake Tanganyika in 1980 and it is characteristic that most piscivores (4 species), most omnivores and a few zoobenthos feeders (2 species) wcre ubiquitous. Expand

It is suggested that the emancipation of males from brood care is attributed to the benthic life of young in Lamprologus furcifer. Expand

It is highly likely that, because of the imperatives for improvements in fish farming, our understanding of fish biology has progressed more in the last two decades than during any similar period.Expand

A super-abundance of shrimps may allow the coexistence of shrimp-eaters with different foraging techniques, and furthermore, their coexistence itself may promote cooperative group-foraging among them. Expand
