Genetic diversity of sub-Saharan African goats was assessed using 19 microsatellite markers. Breeds were sampled from eastern Africa (Maasai, Kigezi, Mubende, North West Highland, Arsi-Bale), southern Africa (Ndebele, Pafuri) and West Africa (West African Dwarf, Maure, Djallonke). European breeds (Grisons Striped, Toggenburg), Asian breeds (Mongolian Cashmere, Bandipur) and a Middle East breed ...

During the Northern hemisphere winter season, biomass burning is widespread in West Africa, yet the total tropospheric column ozone values (<30 DU) over much of the Tropical Atlantic Ocean (15 N–5 S) are relatively low. At the same time, the tropospheric column ozone values in the Southern Tropical Atlantic are higher than those in the Northern Hemisphere (ozone paradox). We examine the causes ...

Ebola viral disease (EVD) is a severe and life-threatening disease. The current Ebola outbreak in West Africa entered its second year and is unprecedented because it is the largest one in history, involved urban centers and affected a large number of health care workers. It quickly escalated from medical into a humanitarian, social, economic, and security crisis. The primary pillars to prevent ...

In this paper we use data from 17 African nations in order to investigate the hypothesis that monetary union – represented in this case by the CFA Franc Zone – augments the extent of macroeconomic integration. The paper covers a number of dimensions of integration including the volume of bilateral trade, real exchange rate volatility and the magnitude of cross-country business cycle correlation.

Africa presents the most complex genetic picture of any continent, with a time depth for mitochondrial DNA (mtDNA) lineages >100,000 years. The most recent widespread demographic shift within the continent was most probably the Bantu dispersals, which archaeological and linguistic evidence suggest originated in West Africa 3,000-4,000 years ago, spreading both east and south. Here, we have carr...

The sequences of the coat protein gene of a representative sample of 40 isolates of Rice yellow mottle virus (RYMV) from 11 African countries were analysed. The overall level of nucleotide diversity was high (approximately 14%). Great geographical distances between the sites where isolates were collected were consistently associated with high genetic distances. In contrast, a wide range of gene...

Understanding the evolutionary relationships of Trypanosoma (Duttonella) vivax genotypes between West Africa and Southern Africa can provide information on the epidemiology and control of trypanosomosis. Cattle blood samples from Zambia and Ghana were screened for T. vivax infection using specie-specific PCR and sequencing analysis. Substantial polymorphism was obtained from phylogenetic analys...

The Caribbean, as with other parts of the New World, has been shaped by racialized constructs since the beginning of its modern history in the late 15 Century. Caribbean history is closely related the emergence of modern racism, usually dated at the point of the encounter between Europe, Africa and the New World. Feminist scholars have contributed a great deal towards deconstructing the categor...
