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.",
