Resumo
Foi desenvolvido um estudo comparativo do comportamento fenológico de nove espécies arbóreas no Parque Estadual da Serra do Mar, Núcleo Picinguaba, Ubatuba, SP, em três formações florestais contíguas: floresta de restinga, floresta de planície e floresta de encosta. As observações foram realizadas de novembro/1994 a abril/1996. A intensidade dos eventos fenológicos foi estimada para cada indivíduo, utilizando uma escala de 0 a 4 com um intervalo de 25% entre cada classe. As espécies mantiveram os mesmos padrões fenológicos, independente da floresta, exceto duas delas (Guatteria australis St.Hill. e Didymopanax calvum Decne. & Planch.). A heterogeneidade dos padrões individuais, exibida por estas espécies, pode estar relacionada a diferenças estruturais entre as formações florestais amostradas, tais como a altura do dossel e umidade do solo.
A study was carried out to compare the phenological patterns of nine tree species from three contiguous Atlantic forest types: restinga forest, coastal-plain forest and Atlantic (premontane) rain forest. The study was conducted at Núcleo Picinguaba, Ubatuba Municipality, São Paulo State (23º22' S and 44º48' W), Brazil, from November/1994 to April/1996. The intensity of phenological events was estimated for each tree according to a scale ranging from 0 to 4, with a 25% interval between the classes. The species presented the same phenological patterns across the forest types in the study area, except for two species (Guatteria australis St.-Hill. and Didymopanax calvum Decne. & Planch.). The heterogeneity of individual patterns exhibited by these species may be related to structural differences among the forest types, such as canopy height and soil humidity.
