BACKGROUND : In Northern Botswana, rural communities, livestock, wildlife and large numbers of mosquitoes cohabitate around permanent waters of the Okavango Delta. As in other regions of sub-Saharan Africa, Rift Valley Fever ...

Understanding factors that drive species richness and turnover across ecological gradients is important for insect conservation planning. To this end, we studied species richness e energy relationships and regional versus ...
