Tree Regeneration Under Different Land-Use Mosaics in the Brazilian Amazon’s “Arc of Deforestation”
We studied the tree-regeneration patterns in three distinct agricultural settlements in the Eastern Amazon to test the influence of land-use mosaics. The following questions are addressed: are the floristic structure and composition of regenerating trees affected by the various land-use types applie...
