Leaf Pressure Volume Data in Caxiuana and Tapajos National Forest, Para, Brazil (2011)

Author(s): Powell T; Moorcroft P


Dataset Information

Site ID: BR-Cax; BR-Sa1

Site Name: Caxiuana Forest-Almeirim; Santarem - K67

Variables: Leaf Area; Leaf pressure-volume (PV) parameters

Date Range: Jan. 11, 2011 - July 30, 2011

Description: Pressure volume curve measurements on leaves of canopy trees from the from the Caxiuana and Tapajos National Forests, Para, Brazil. Tapajos samples were harvested from the km 67 forested area, which is adjacent to the decommissioned throughfall exclusion drought experimental plot. Caxiuana samples were harvested from trees growing in the throughfall exclusion plots. Data were collected in 2011. Dataset includes: date of measurement, site ID, plot ID, tree ID (species, tree tag #), leaf area, fresh weight, relative weight, leaf water potential, and leaf water loss. P-V curve parameters (turgor loss point, osmotic potential, and bulk modulus of elasticity) can be found in Powell et al. (2017) Differences in xylem cavitation resistance and leaf hydraulic traits explain differences in drought tolerance among mature Amazon rainforest trees. Global Change Biology.

QA/QC: Full QA-QC

QA/QC Method: Third to fifth healthy leaf from apex was harvested. Spurious data were removed. See Powell et al. (2017) for complete details about measurements and processing.
