Fenologia reprodutiva e distribuição espacial de Oeceoclades maculata (Lindl.) Lindl. (Orchidaceae) em Cerrado do município de Mogi Guaçu, São Paulo, Brasil

摘要: Oeceoclades aculate (Lindl.) Lindl., an invasive orchid, was analyzed as to its reproductive phenology and spatial distribution, correlation between abundance of mature immature individuals, verifying these with microclimate patterns in the Cerrado (savanna-like vegetation) Mogi Guacu, Sao Paulo State, Brazil. For reproductive phenology 100 plants were followed distribution pattern identifi ed by Morisita Index (MI) and Variance Ratio/Average ® 20 plots 20x10m, reduced 10x10m afterwards. The phenology presented seasonality, fl owering from November February, fructifi cation February June, dehiscence June July. Mature immature individuals aggregated correlated each other, indicating dependence ontogenetic stages. The luminosity preponderant microclimatic factor allocation plants. Seasonal climatic changes intensity anthropogenic disturbances seem be more important for establishment species than microclimate.
