CEP 13565-905, São Carlos, SP Brazil 1 Abstract The hypothesis that forest disturbance is important for the recruitment of the large arborescent palms Attalea maripa was tested with a natural experiment in the Pinkaití site (7o 46’S; 51o 57’W), a seasonally-dry Amazonian forest.
A 8,000 m long trail, that crosses, in its lower half, an open forest along the Pinkaití stream bottomlands and, on its upper half, a dense forest on a hill, was divided in 160 0.15 ha (50x30 m) sampling units.
At each unit, adult palms were counted and percentage of canopy openness was measured with a concave spherical densiometer.
The palms were nearly five times more abundant at...
