The African lion has declined to <35,000 individuals occupying 25% of its historic range. The situation is most critical for the geographically isolated populations in West Africa, where the species is considered regionally endangered. Elevating their conservation significance, recent molecular studies establish the genetic distinctiveness of West and Central African lions from other extant Afr...
INTRODUCTION Integration is a phenomenon that has been gaining ground the world over. It can be seen in the Americas in the forms of a customs unions like MERCOSUR (South America) or a free trade area like NAFTA (North America), a common market in Europe with the EU, and regional cooperation in Asia with ASEAN. It comes as no surprise therefore that Africa would be on the verge of the developme...
West Africa is known to be particularly vulnerable to climate change due to high climate variability, high reliance on rain-fed agriculture, and limited economic and institutional capacity to respond to climate variability and change. In this context, better knowledge of how climate will change in West Africa and how such changes will impact crop productivity is crucial to inform policies that ...
OBJECTIVES To carry out a meta-analysis to assess the prevalence of four key breastfeeding indicators in four subregions of 29 sub-Saharan African countries. DESIGN, SETTINGS AND PARTICIPANTS The 29 countries were categorised into four subregions, and using cross-sectional data from the most recent Demographic and Health Surveys (2010-2015) of these countries prevalence of each of four key br...
Hepatitis C virus (HCV) is classified into seven genotypes based on genetic diversity, and most genotypes have been found in Africa. Infections with HCV genotype 2 (HCV2) are most prevalent in West Africa and it was suggested that HCV2 originated in West Africa. To better understand the evolutionary epidemiology of HCV2 in Africa, we examined new NS5B sequences of HCV2 strains obtained from Côt...
To investigate the presence of Lagos bat virus (LBV)-specific antibodies in megachiroptera from West Africa, we conducted fluorescent antibody virus neutralization tests. Neutralizing antibodies were detected in Eidolon helvum (37%), Epomophorus gambianus (3%), and Epomops buettikoferi (33%, 2/6) from Ghana. These findings confirm the presence of LBV in West Africa.
Cowpea (Vigna unguiculata spp unguiculata) is adapted to the drier agro-ecological zones of West Africa where it is a major source of dietary protein and widely used as a fodder crop. Improving the productivity of cowpea can enhance food availability and security in West Africa. Insect predation--predominately from the legume pod borer (Maruca vitrata), flower thrips (Megalurothrips sjostedti) ...
This article examines the diverse research views on the history of urban centres in West Africa. I focus on the characteristics of some of the past urban centres at the time of their peak populations as revealed from the archaeological record. This article concludes that the quantum of research in West Africa is insignificant relative to the vast potentials for research to be conducted there. T...
BACKGROUND There is an urgent global need to strengthen rehabilitation services for people with disabilities. In sub-Saharan Africa, rehabilitation services for people with communication disabilities continue to be underdeveloped. A first step in strengthening services for people with a communication disabilities is to understand the composition and conditions of the current workforce. OBJECT...
