Sociabilidade de espécies da mata atlântica com a exótica invasora Artocarpus heterophyllus Lam.

Abstract

Sociability of Atlantic Forest species with the alien Artocarpus heterophyllus Lam. - The aim of this study was to evaluate the sociability of the northeastern Atlantic Forest species with invasive exotic A. heterophyllus, seeking to guide control programs and recovery areas invaded by taxon. In 10 plots of 100 m² containing in their geometric centers one adult specimen of A. heterophyllus, all tree species were recorded. By means of the index of association (IA) and the Pearson correlation coefficient (ρ) evaluated the performance of native species (given by the arithmetic mean between the IA the ρ). The average number of individuals of A. heterophyllus per share was 1,195.5 ± 846.8. 44 species were found and two morphospecies associated with invasive exotic, of which 19 had more than five individu- als and were categorized as to their performance. The list of species associated with A. heterophyllus, many have ecological attributes that allow the replacement of invasive exotic.
