Savanna biomass production, N biogeochemistry, and cycling : a comparison between Western Africa (Ivory Coast and Burkina Faso) and the Venezuelan Llanos
Résumé
Many studies examined the biomass accumulation, productivity and nutrient cycling of the grassy to woody savannas of Western Africa and the Venezuelan Llanos (Orinoco savannas). Yet, a comparative synthesis of that information for well extended territories on both sides of the Atlantic has not formally been presented. Those savannas, although strongly differing in soil parent material origin and human occupancy, are similar with respect to many features of soil-plant relationships, pedofauna activities, relief and climate.
