Table 2.
Leaf and plant attributes of Palicourea padifolia and Psychotria elata in two cloud forests of different successional status in Río Macho, Costa Rica: secondary young forest (SYF) and secondary old forest (SOF). Values are mean and standard deviation. Significant differences between sites across species are represented by the univariate ANOVA extracted from MANOVA
