This paper presents a map of Africa's rainforests for 2005. Derived from moderate resolution imaging spectroradiometer data at a spatial resolution of 250 m and with an overall accuracy of 84%, this map provides new levels of spatial and thematic detail. The map is accompanied by measurements of deforestation between 1990, 2000 and 2010 for West Africa, Central Africa and Madagascar derived fro...

BACKGROUND M. africanum West African 2 constitutes an ancient lineage of the M. tuberculosis complex that commonly causes human tuberculosis in West Africa and has an attenuated phenotype relative to M. tuberculosis. METHODOLOGY/PRINCIPAL FINDINGS In search of candidate genes underlying these differences, the genome of M. africanum West African 2 was sequenced using classical capillary sequen...

West African Dwarf (WAD) goats are extremely important in the rural village economy of West Africa, but still little is known about their biology, ecology and capacity to cope with gastrointestinal nematode (GIN) infections. Here, we summarise the history of this breed and explain its economic importance in rural West Africa. We review recent work showing that Nigerian WAD goats are highly tryp...

Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogeneti...

Phosphorus (P) deficiency is a major constraint to crop production on highly weathered, lowactivity clay soils in the humid zone of West Africa. Past research suggested a linear relationship between grain yield and P uptake over a range of fertilizer P applied to upland rice cultivars. However, there is lack of information on how these relationships are affected by the long-term fertilizer ...

We compiled all credible repeated lion surveys and present time series data for 47 lion (Panthera leo) populations. We used a Bayesian state space model to estimate growth rate-λ for each population and summed these into three regional sets to provide conservation-relevant estimates of trends since 1990. We found a striking geographical pattern: African lion populations are declining everywhere...

(August 2012) Elizabeth Carrera, B.L.A., Texas A & M University Co-Chairs of Advisory Committee: Dr. Kirk O. Winemiller Dr. Luis A. Hurtado The African bonytongue (Heterotis niloticus), one of two living species of the primitive teleost family Arapaimida...

END MARKET OPPORTUNITIES MARKET OVERVIEW Throughout Africa and in humid West Africa in particular, small ruminants must be considered primarily as sources of meat and meat products. There is ample evidence from several African regions that demand for meat is strong and increasing. This reflects greater urbanization and associated higher incomes, which have led to large domestic and internationa...

Yam is a major staple in West and Central Africa and an important supplementary food in East Africa. Three varieties of yam are grown in Sub-Saharan Africa (SSA), though only two are indigenous to the region. White yam (D. rotundata) and yellow yam (D. cayenensis) are native to West Africa, and the production area stretches from central Cote d‘Ivoire to Cameroon. East African production of wate...
