The haplochromine cichlid fishes of Lake Victoria (LV), East Africa, are a textbook example of adaptive radiation-a rapid divergence of multiple morphologically distinguishable forms from a few founding lineages. The forms are generally believed to constitute a "flock" of several hundred reproductively isolated species in a dozen or so genera. This belief has, until now, not been subjected to a...

Abstract Despite their high abundance and species richness, tilapiines have been compromised by various factors especially overfishing, climate change, uncontrolled fish transfers introductions. Fish introductions negatively impacted native tilapiine populations through competition, predation, hybridization, introgression compromising genetic integrity. The hybridization levels of different in ...

1 T explosive speciation of cichlid fishes in the African great lakes has intrigued biologists for many decades. Interest was revitalized in 1996 after the publication in Science of geological data1 indicating that the youngest lake, Lake Victoria, must have been completely dry during the most recent Ice Age – perhaps as recently as 12 400 years ago. This implies that the approximately 500 hapl...

The cichlid fishes of Lake Malawi are famously diverse. However, evolutionary studies have been difficult because of their recent and uncertain phylogenetic history. Portions of 12 nuclear loci were sequenced in nine rock-dwelling species (mbuna) and three representatives of pelagic nonmbuna species. In contrast to the pattern of variation at mitochondrial genes, which do provide phylogenetic r...

The virus was first isolated in April 1947 from a rhesus macaque monkey placed cage the Ziika Forest of Uganda, near Lake Victoria, by scientists Yellow Fever Research Institute. A second isolation mosquito A. africanus followed at same site January 1948. When developed fever, researchers its serum
