Abstract

RUOKOLAINEN, Kalle et al. COMPARACION FLORISTICA DE DOCE PARCELAS EN BOSQUE DE TIERRA FIRME EN LA AMAZONIA PERUANA. Acta Amaz. [online]. 1994, vol.24, n.1-2, pp.31-48. ISSN 1809-4392.  https://doi.org/10.1590/1809-43921994242048.

Floristic composition of twelve plots, 25 m by 25 m, was studied in the Peruvian Amazonia in order to investigate if it were possible to use a part of the flora as an indicator of the changes observed in other components of the flora. Floristic similarities among the plots were calculated using six different taxonomic or physiognomic groups: ferns, the families Melastomataceae and Myristicaceae, trees thicker than 2.5 cm diameter at breast hight (DBH), trees between 2.5 cm and 5 cm DBH, and trees thicker than 5 cm DBH. The similarities were used for agglomerati ve classifications of the plots and for analyzing the correlations among the different groups of plants with Mantel's test. The results indicate that floristic changes were similar in all of the groups and therefore every group can potentially be used as an indicator.

Keywords : Amazonia; ferns; Mantel's test; Melastomataceae; Myristicaceae; phytosociology.
