This record of lake levels and changing limnological conditions provides a framework for interpreting the evolution of the Lake Malawi fish and invertebrate species flocks and places new constraints on models of Afrotropical biogeographic refugia and early modern human population expansion into and out of tropical Africa.
THE NILE PERCH IN LAKE VICTORIA: INTERACTIONS BETWEEN PREDATION AND FISHERIES
A bioenergetics model of Nile perch predation rates was used to evaluate the consequences of previous, current, and future fishery exploitation patterns and their ecological implica- tions and produced three main conclusions.
Molecular systematics and radiation of the haplochromine cichlids (Teleostei: Perciformes) of Lake Malawi
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.

A continuous, first-of-its-kind 1.3-My record of continental hydroclimate and lake-level variability derived from drill core data from Lake Malawi is presented, resulting in large-scale changes in one of the world’s largest lakes and most diverse freshwater ecosystems.

Investigation of the feeding; habits of a group of tropical herbivorous rock-dwelling cichlid fishes from Lake Malawi, Africa, finds diet was correlated with foraging behavior and trophic morphology and could possibly facilitate ecological coexistence among various species.
Social behaviour, foraging efficiency and habitat utilization in a group of tropical herbivorous fish
The mixed-species schooling appears to be a means by which acanthurids can forage in a microhabitat on a preferred resource while circum venting the territoriality of a herbivorous competitor.
The Barrier Reef sediment apron: Tobacco Reef, Belize
Sedimentological and biological surveys of the back-reef sediment apron of Tobacco Reef, a continuous segment of the Belizean Barrier Reef, reveal five distinct biogeological zones: (1)…
Fish fossils as paleo-indicators of ichthyofauna composition and climatic change in Lake Malawi, Africa
Abstract Numerous biological and chemical paleorecords have been used to infer paleoclimate, lake level fluctuation and faunal composition from the drill cores obtained from Lake Malawi, Africa.…
Spatial and Temporal Variations in Grazing Pressure by Herbivorous Fishes: Tobacco Reef, Belize
The Gross Intestine Morphology of a Group of Rock-Dwelling Cichlid Fishes (Pisces, Teleostei) From Lake Malawi
- P. Reinthal
If intestine length is responsive to changes in diet, this permits flexibility in the range of dietary items that a particular individual or lineage may consume, and characterize the adaptive radiation of the family Cichlidae and facilitate ecological coexistence in these high diversity assemblages.
