             abstract = "The Brazilian Atlantic forest has been reduced to remnants 
                         constituting only 12% of its original extent. Because of the 
                         extensive fragmentation, any climatic change can affect its 
                         stability. Using a database of structure and floristics of trees, 
                         we estimated above ground biomass (AGB) at a regional spatial 
                         scale for the Atlantic Forest biome for both seasonal dry forest 
                         (18 fragments) and also rainforest (10 fragments). We aimed to 
                         assess whether there is a spatial variation in AGB and carbon 
                         stock in Atlantic forest fragments dependent on factors related to 
                         forest type (climate) and fragmentation (fragment size). It is 
                         expected that: (1) rainforest present higher biomass than dry 
                         forest; (2) smaller fragments has less biomass than larger 
                         fragments. The AGB of the rainforest was 100 tons higher than the 
                         dry forest values. Rainfall and seasonality are the main 
                         determinant of the type of forest in the Atlantic region, in 
                         addition it is known that the dry tropical forests are 
                         ecologically and floristic distinct to rainforest. Therefore, a 
                         specific dynamics of carbon storage in trees was expected. Our 
                         results are in agreement with previous reports of a diminishing in 
                         biomass in smaller fragments of Atlantic forests, as a direct 
                         effect of fragment size. However, this relationship was not 
                         verified considering dry forests fragments alone, which have a 
                         more intense degradation, that can be a change factor of trees 
                         biomass, hiding the edge effect of the fragment. In the context of 
                         this research, one question was addressed: In which sense 
                         fragmentation intensifies climate action? The resilience of 
                         tropical forest fragments to climate change is unclear, but this 
                         research will enable to make more accurate predictions of carbon 
                         balance at a large spatial scale for the Atlantic Forest biome in 
                         the future.",
