Leaf C and N content by leaf age, Feb2017, PA-SLZ: Panama

This dataset contains carbon, hydrogen and nitrogen content measurements of sunlit canopy leaves of Apeiba membranacea (APEIME), Guatteria dumetorum (GUATDU), Miconia borealis (MICOBO), Terminalia amazonia (TERMAM), Virola multiflora (VIROSP) and Vochysia ferruginea (VOCHFE) species. Data was collected from the NGEE-Tropics Bosque Protector San Lorenzo (PA-SLZ) site in Panama in February of 2017 as part of the 2017 Brookhaven National Lab–Smithsonian Tropical Research Institute leaf traits by age campaign. A PDF with full sapling protocol is included in this dataset, along with metadata files in Excel file format. Data is in both CSV (Panama2017_CHN.csv) and Excel file formats. See related datasets for further sample details, leaf spectra, sap flow, leaf water potential, leaf mass per area (LMA), and gas exchange measurements. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: This research was supported as part of NGEE-Tropics, funded by the U.S. Department of Energy, Office of Science, Office of Biological and Environmental Research under contract no.
