Table 1.
Neighbourhood and light characteristics of all the studied plants as estimated by interference measures and hemispherical canopy photography 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 are represented by the univariate ANOVA extracted from MANOVA
