| Abstract | In the past few decades, the role of natural and human-induced fire regimes and disturbances have received considerable attention in ecosystem studies. Most investigations focus on anthropogenic fire disturbances particularly associated to tropical degradation in South America, mostly due to cropland and pastureland expansion. Although human-triggered fires practically overcome the effects of natural fire events in this tropical zone, understanding and modeling the natural dynamics of the forest-savanna transition remain an open issue particularly because tropical savannas and tropical forests may occur under the same climatic envelope in portions of this tropical region. In this context, a simple and conceptual climate-vegetation-natural fire (CVNF) model is proposed to investigate the role of natural fires on forest-savanna transition dynamics in tropical South America. Quantitative results of this model support ecological theories and observational evidences, suggesting that lightning-triggered fires play a significant role in determining the location of the tropical forest-savanna boundary in South America. Our model calculations suggest that in the absence of fires, tropical forests would extend about 300 km into the presently-observed savanna domain. |
