Key questions about its origin remain poorly characterized, such as the importance of speciation versus polymorphism, whether species persist on evolutionary time scales, and if speciation happens more commonly in small isolated or in large … Fast adaptive responses in the oral jaw of Lake Victoria cichlids ; adaptive radiation. The dramatic ecological changes in Lake Victoria provide a unique opportunity to study environmental effects on cichlid morphology. This study shows how four haplochromine cichlids adapted their premaxilla to a changed diet over the past 30 years.

East Africa’s Lake Victoria, famous for its stunning adaptive radiation of cichlids, has suffered from human-induced eutrophication over the past decades. A pharyngeal jaw evolutionary innovation facilitated extinction in Lake … ; 27-11-2015 · In Lake Tanganyika, which hosts an older cichlid radiation than Victoria and Malawi, non-pharyngognathous Lates species and the pharyngognathous cichlids coexist, albeit with many fewer cichlid species and a lower speciation rate than the other two radiations (22, 24). 47.1: The Biodiversity Crisis - Biology LibreTexts ; 30-06-2019 · The cichlids of Lake Victoria are the product of an adaptive radiation. An adaptive radiation is a rapid (less than three million years in the case of the Lake Victoria cichlids) branching through speciation of a phylogenetic tree into many closely related species; typically, the species “radiate” into different habitats and niches. The Galápagos finches are an example of a modest adaptive radiation … African cichlid fish: a model system in adaptive radiation research ; 22-08-2006 · The African cichlid fish radiations are the most diverse extant animal radiations and provide a unique system to test predictions of speciation and adaptive radiation theory. The past few years have seen major advances in the phylogenetics, evolutionary biogeography and ecology of cichlid fish. Most Cichlid - Wikipedia ; Examples include many East African Rift lakes (Lake Malawi, Lake Tanganyika and Lake Victoria) endemics, e.g.: Maylandia, Pseudotropheus, Tropheus, and Astatotilapia burtoni, along with some South American cichlids such as Geophagus steindachneri. 若い情熱 ページ
