TL;DR: In this paper, the authors show that part of the productivity of the Amazon rain forest is dependent upon critical trace elements contained in the soil dust originating in the Sahara/Sahel, and they conclude that the major ionic composition of rain water in the CAB wet season may be strongly influenced by inputs of material originating on the African continent nearly 5000 km away.

TL;DR: In this paper, the authors described the tropical air trajectories that occurred during the Southern African Fire-Atmosphere Research Initiative (SAFARI) in terms of a circulation classification scheme and the vertical stability of the atmosphere.

TL;DR: In this article, the Kalahari region of southern Africa was analyzed to analyze climate effects on nutrient cycling, and the importance of biogenic N2 fixation associated with vascular plants was estimated with foliar δ15N and the basal area of leguminous plants.

TL;DR: In this article, the mean annual rainfall in southern Africa is found to explain over half of the observed variance in the stable nitrogen (N) isotopic signatures of C3 vegetation in Southern Africa (r2=0.54, P<0.01).
