             abstract = "Some coupled carbon/climate models are predicting globally 
                         significant changes in Amazon carbon and water cycles for the near 
                         future, with conversion of forest to savanna like vegetation. 
                         Facing this scenario, we estimate the forest-savanna mosaic 
                         extensions and directions of changes within 20 years in a 
                         transitional area in Northern Brazilian Amazonia, and investigated 
                         if conservation status and rainfall changes have influenced the 
                         mosaic dynamics. Applying spectral linear mixture model to a 
                         Landsat-5-TM time series, we identify protected savanna enclaves 
                         within a strictly protected nature reserve (ESEC Marac{\'a}) and 
                         its outskirts non-protected forest islands and compared theirs 
                         areas among 1986/1994/2006. Forest-savanna mosaic dynamics have 
                         being primarily mediated by climate and secondly by disturbance 
                         events. The protected savanna enclaves decreased 2.62 ha on 
                         average in 20 years with greater reduction rate in higher 
                         precipitation regime, whereas the non-protected forest islands 
                         remained stable overall, balancing an encroaching onto savanna 
                         during humid decades and with savannization in reduced rainfall 
                         periods. Thus, keeping favorable climate conditions, the ESEC 
                         Marac{\'a} conservation status will proceed favoring the forest 
                         encroaching onto savanna while the non-protected outskirt areas 
                         will be resilient to disturbance regimes. However, if confirmed 
                         the increase of dry events frequency predicted by climate models 
                         for this region, the future changes in extension and directions of 
                         forest limits will be affected, disrupting ecological services as 
                         carbon stock and local biodiversity.",
