COMPARACION FLORISTICA DE DOCE PARCELAS EN BOSQUE DE TIERRA FIRME EN LA AMAZONIA PERUANA Acta Amazonica
RUOKOLAINEN,Kalle; TUOMISTO,Hanna; RÍOS,Richer; TORRES,Alberto; GARCÍA,Mildred.
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...

Similar understorey structure in spite of edaphic and floristic dissimilarity in Amazonian forests Acta Amazonica
SUOMINEN,Lassi; RUOKOLAINEN,Kalle; PITKÄNEN,Timo; TUOMISTO,Hanna.
Forest structure determines light availability for understorey plants. The structure of lowland Amazonian forests is known to vary over long edaphic gradients, but whether more subtle edaphic variation also affects forest structure has not beenresolved. In western Amazonia, the majority of non-flooded forests grow on soils derived either from relatively fertile sediments of the Pebas Formation or from poorer sediments of the Nauta Formation. The objective of this study was to compare structure and light availability in the understorey of forests growing on these two geological formations. We measured canopy openness and tree stem densities in three size classes in northeastern Peru in a total of 275 study points in old-growth terra firme forests...
