Nothofagus regeneration in treefall gaps in northern Patagonia
In the rain shadow of the Andes in northern Patagonia, the evergreen beech Nothofagusdombeyi occurs in mixed stands with the xeric trees Austrocedruschilensis and (or) Nothofagusantarctica. In two old-growth stands (>150 years old), size and age structures, treefall patterns, and regeneration...

In the rain shadow of the Andes in northern Patagonia, the evergreen beech Nothofagusdombeyi occurs in mixed stands with the xeric trees Austrocedruschilensis and (or) Nothofagusantarctica.

In the stand codominated by N. dombeyi and Austrocedrus, recruitment of both species occurs in small treefall gaps. The relative proportions of treefalls and potential successors in gaps imply that gap-phase regeneration is maintaining this stand in compositional equilibrium. In the second stand, N. antarctica was formerly a common canopy tree, but currently is not regenerating in treefall gaps; gaps are occupied instead by N. dombeyi.
