Title biomass data
Downloaded 18 times
Description These are observations on biomass, which form the core of the study. See Supplemental Figure S1 for a graphical representation. COLUMN HEADINGS: 'spcode' the number of the species (names available in 'species data' file). 'house': Which shadehouse did the seedling grow in? 'indiv' Which individual was the observation made on?, 'light' the light (in %) in the shadehouse. 'day' how many days since the start of the study did the observation occur? 'biomass': the estimated biomass on this day in grams (see Methods for details on how biomass was estimated).

Title Species descriptions
Downloaded 13 times
Description THis is basically Table 1. It summarises chaarcteristics of each species used in the study, linking the species codes (spcode) to the famil, genus and species of each taxon. column 'deciduous' indicates whether the species is deciduous or evergreen. Max height is in meters. Successional stage gives the rough shade tolerance of the taxon.

Title harvest data
Downloaded 12 times
Description This file contains data from the two destructive harvests. The first six columns are just like in the biomass data file. 'Harvest' indicates which of the two harvests the observation was made. 'date' gives the number of days since the start of the study of the harvest. 'height' is the height of teh measured individual. girth_1 and girth_2 are two perpendicular basal diameters of the stem. BiomassR, BiomassS, BiomassL, and BiomassA give, respectively, the individual's biomass of roots, stem, leaves and all (the sum of the three prior). THickness gives leaf thickness in micrometers (measured only at harvest 3). Leaf area is leaf area of the individual, in cm^2.

Title gas exchange data
Downloaded 14 times
Description This file provides details on rates of gas exchange made at the time of the second harvest. The first six columns are just as in the biomass data file. 'Area' represents the leaf area measured for photosynthetic rate in the cuvette, in cm^2. 'N' leaf nitrogen concetration, on a mass basis, in percent. 'thickness': leaf blade thickness, in micrometers. 'LMR' leaf mass ratio. 'Lcp' Light compensation point - the amount of light (in µmol m-2·s-1) at which photosynthesis is zero. 'Amax': the predicted maximal rate of photosynthesis per unit area in CO2·m-2·s-1. SLA_photo: specific leaf area, 'Amass': predicted maximal photosynthetic rate per unit leaf biomass in nmol CO2·g-1·s-1.
