The spatial distribution pattern of the univariate individuals of M. flexuosa was carried out for each category using the transformation G (t) of the function K (t) (Besag and Diggle 1977; Ripley 1977, 1979, 1981). The significance (P d” 0.01) of L (T) function was determined based on Monte Carlo simulations (Besag and Diggle 1977; Marriott 1979). For the bivariate function K (12), point type “1” and point type “2” were added to test the hypothesis of spatial dependence between two data groups, also using the transformation G (t), maintaining the significance and simulations of Monte Carlo. The function simulations K (t), K (12) and Monte Carlo were obtained using the TOOLBOX software (Fisher 2000). K (t) Ripley’s was used to analyze the spatial distribution of all classes of individuals. Regarding to K (t) 12, a comparison was made concerning mature (adult) X immature (Infantile + Juvenile) individuals and a comparison between M. flexuosa and the other more abundant species.

Results and Discussion Sampling resulted in 578 individuals belonging to 54 species, 41 genera and 26 botanical families (Table 1). The number of species was relatively high since it was an area with a monodominant species, according to Connell and Lowman (1989), the dominance of a single species can reduce diversity. These circumstances might be explained by the location of the area being in an Ecological Tension Zone, closer to the Amazon, which according to Ratter (1992) are, in general, a floristically more diverse region. Marimon and Felfili (2000) in their study in a monodominant Brosimum rubescens Taub forest recorded 57 species. Sander et al. (2017) recorded only 25 species in a monodominant M. flexuosa forest. Arieira and Nunes da Cunha (2006) sampled in five plots of a monodominant Vochysia divergens Poul. flooded forest in North Pantanal and recorded 83 species. Ferreira and Almeida (2005) recorded 30 species in a “igapó” (flooded area), and 19 species in a forest flooded by white water rivers.
