Gaps, semideciduous mesophyll forest, regenerationAbstract
This study describes the composition and structure of 21 gaps occurring in semideciduous mesophyll forest in the Parque Estadual das Fontes do lpiranga Reserve, São Paulo, southeastern Brazil. The origin and size of gaps were determined and the number and height of tree species colonizing the gaps were recorded. Falling trees and branches created 66% of ali gaps and the others origin was unknown. Most gaps (71%) were small (20 to 40m²). Seven species were founded exclusivelyin larger gaps (more than 100m2), 48 were founded only in smaller gaps (less than 60m2) and 14 occurred indifferently. The three commonest species in gaps were included between the most importante species in a phytosociological study carried out in the area. This fact, and the great number (69) of species founded, suggest that gaps play an important role in the dynamics of the studied forest.
