Estrutura populacional e distribuição espacial de Theobroma speciosum Willd.ex Spreng (cacauí) na floresta nacional do tapirapé-aquiri / Population structure and spatial distribution of Theobroma speciosum Willd.ex Spreng (cacauí) in the national forest of tapirapé-aquiri

Abstract

population structure and dynamics in the Amazon focus on genetic, ecological and successive knowledge of tropical species. Thereafter, the population structure and spatial distribution of Theobroma Speciosum (cacauí) on six permanent plots in the Tapirapé-Aquiri National Forest were analysed. The species was identified by size classes, separated by trees with DAP 10 cm, strawberries 5 DAP 10, and DAP 5 regeneration. The spatial distribution pattern was determined by the Morisita Dispersion Index (Id). The result was 1,94 showing an aggregate distribution in the 35 individuals sampled. There was a significant difference between the abundance of populations in size classes, with few significant regenerative individuals on the plots, with the largest restricted to the upper diameter class (10 cm — 15 cm). Those data indicate that that species is sensitive and susceptible to fragmentation, demonstrating a limitation of the species to establish regeneration in the forest.
