| Resumen en inglés | The objective of this study was to verify the possible differences of the light patterns during the winter of the year of 2003 (June 21 to September 23) for different conditions of the vegetation mosaic, including the four main forest formations of the state of São Paulo (Semideciduous Seasonal Forest - Floresta Estacional Semidecidual, Sub-Montane Ombrophilous Dense Forest - Floresta Ombrófila Densa Sub-Montana, Xeromorphic Coastal Dune Forest Resting - Floresta de Restinga and Advanced Succesional Stage of Forest - Forest Savana). The tested hypothesis was that differences exist so much inside as among each of those formations by PPFD (Photosynthetic Photons Flux Density) received during the winter, even considering that this station presents the smallest variation widths of the solar radiation along the days. This research project was inserted in the Biota Thematic Project /FAPESP — Permanent Plots (1999/09635-0), which maintains a permanent plot of 10.4 hectares in four different conserved fragments of Semideciduous Seasonal Forest, Sub-Montane Ombrophilous Dense Forest, Xeromorphic Coastal Dune Forest (Restinga) and Advanced Succesional Stage of Forest (Forest Savana), located in the municipal districts of Gália, Sete Barras, Ilha do Cardoso/Cananéia and Assis, respectively. Inside each of those plots were chosen parts, for which the following conditions of the vegetation mosaic were considered: Semideciduous Seasonal Forest and Sub-Montane Ombrophilous Dense Forest: Center of Large Gap, Internal Edge of Large Gap, External Edge of Large Gap, Center of Small Gap, Understorey far 10 meters from the Boundary of Large Gap (1m in direction to the gap), Understorey far 20 meters from the Boundary of Large Gap (1m in direction to the gap) and Understorey under Evergreen Canopy. To the Forest of Restinga, the studied conditions were: Center of Large Gap, Internal Edge of Large Gap, External Edge of Large Gap, Center of Small Gap, Understorey far 20 meter |
