The prevalence of malaria among the residents of the Lake Victoria basin remains high. The environment associated with the lake may maintain a high number of malaria vectors. Lake habitats including water hyacinths have been suspected to be the source of vectors. This study investigated whether malaria vectors breed in the lake habitats and adjacent backwater pools. Anopheline larvae were colle...

Forty years ago, in early August 1967, the first filovirus ever detected, Marburg virus, made its appearance in Europe, causing severe and often fatal hemorrhagic fever in laboratory workers in Marburg and Frankfurt and, about 4 weeks later, in Belgrade. The etiological agent was isolated and identified by the combined efforts of virologists in Marburg and Hamburg within the very short time of ...

Introduction The Nile River the longest river in the world has been serving as a source of life to the people living in its basin for centuries. Throughout the course of history, the Nile has supported livelihoods and played a considerable role in enriching diverse cultures within its basin. Hence, the Nile has been the centre of attention of explorers, tourists, researchers and historians for ...

Precipitation over Lake Victoria in East Africa greatly influences its water balance. Over 30 million people rely on Lake Victoria for food, potable water, hydropower and transport. Projecting precipitation changes over the lake is vital in dealing with climate change impacts. The past and future precipitation over the lake were assessed using 42 model runs obtained from 26 General Circulation ...

The endemic cichlid fishes in Lake Victoria are a model system for speciation through adaptive radiation. Although the evolution of the sex-determination system may also play a role in speciation, little is known about the sex-determination system of Lake Victoria cichlids. To understand the evolution of the sex-determination system in these fish, we performed cytogenetic analysis in 11 cichlid...

This study documented the population dynamics of Biomphalaria and associated natural infections with digenetic trematodes, along the shores of Lake Albert and Lake Victoria, recording local physicochemical factors. Over a two-and-a-half-year study period with monthly sampling, physicochemical factors were measured at 12 survey sites and all freshwater snails were collected. Retained Biomphalari...

This paper focuses on a neglected factor in literature on the HIV epidemic in sub-Saharan Africa: the role of the eco-social environment in shaping HIV risk. I argue that the changing ecological environment of Lake Victoria, Africa's largest freshwater lake, mapping onto a gendered economy, shaped fisherfolk's sexual relationships and sexual mixing patterns in ways that were consequential for t...

The explosive radiation of cichlid fishes in the African Great Lakes has intrigued biologists for many decades. The faunas of these lakes are outstanding, both in species richness and in the composition of their fish fauna. Several of these lakes contain as many or even more fish species than all the rivers and lakes of Europe together (Lowe-McConnell 1987; Kottelat 1997). About 90% of the fish...
