Mosquito virus diversity in Western and North-western Uganda

Martin N. Mayanja, Marc Niebel, Shirin Ashraf, Maryam N. Hardy et autres

Abstract Introduction Surveillance for mosquito borne arboviruses in Sub Saharan Africa has largely focussed on known viruses including Yellow fever virus (YFV), Rift Valley fever virus (RVFV), Chikungunya virus (CHIKV), West Nile virus (WNV) and Dengue viruses (DENV). Routine surveillance and outbreak …

Genetic consequences of population expansions and contractions in the common hippopotamus (Hippopotamus amphibius) since the Late Pleistocene

Céline Stoffel, Christophe Dufresnes, John B. A. Okello, Christian Noirard et autres

Over the past two decades, an increasing amount of phylogeographic work has substantially improved our understanding of African biogeography, in particular the role played by Pleistocene pluvial-drought cycles on terrestrial vertebrates. However, still little is known on the evolutionary history of semi-aquatic …

Microsatellite DNA Analyses Reveal Population Subdivisions Among the Recently Introduced Nile Perch (Latesspp.) in Lake Victoria

Matthew Tenywa Mwanja, Vincent B. Muwanika, Charles Masembe, Wilson Waiswa Mwanja et autres

Nile perch (Lates spp.) was introduced into Lake Victoria only five decades ago but is now well established and distributed throughout the lake. Given the extensive size of the lake, there is a possibility of isolation by distance that can lead to …

Evolutionary history of Nile perch Lates sp. inferred from mitochondrial DNA variation analyses

Matthew Tenywa Mwanja, Vincent B. Muwanika, Charles Masembe, Silvester Nyakaana et autres

Evolutionary histories of aquatic species are often characterized by distinct patterns of genetic variation, which in part reflect drainage evolution. In the present study, the consequences of paleo-environmental changes on patterns of genetic variation of the mitochondrial DNA control region in Nile …

Population morphological variation of the Nile perch ( Lates niloticus , L. 1758), of East African Lakes and their associated waters

Matthew Tenywa Mwanja, Vincent B. Muwanika, Silvester Nyakaana, Charles Masembe et autres

In this study an attempt was made to determine whether there are morphological variations associated with the different geographical populations of the Nile perch of East Africa. Analyses of the levels of morphological differentiation based on morphological characterisation and variation were carried …
