CSPs: Leaf traits and chemicals from individual trees in the CSPs

Usage Rights

This data is Private.

Dataset Abstract

Leaf traits and chemicals from tree species in the Gutianshan Nature Reserve, including secondary compound (total phenolic and tannin concentrations) and information on stomata.

Dataset Design

Leaf samples were taken from sun-exposed branches with an expandable pruner. Only completely developed leaves were sampled, without visible herbivore damage and preferably free of leaf fungi. Seven leaves were collected per individual and the majority of species was sampled in five to seven CSPs. Every species was sampled only from one individual per CSP. Rare species that occurred with less than five individuals in all CSPs had a correspondingly lower number of replicates.

Data Analysis

Mind that young and old leaves were sampled. For aggregated traits you may want to use old leaves only or aggregate first within both age classes and then average again.
