Description

The data files contains species means, standard deviations (SD), and sample sizes (N) for 36 traits and 20 species. Information on species is listed in Table 1 of the published paper. Methods of the paper describe each trait in detail, and Table 2 provides summary statistics. Missing data are listed as "?". The description of the data file columns is provided below. For traits that were transformed for analysis (see Table 2 of paper), means and SD of transformed values are reported here since standard deviations cannot be properly back-transformed.

(1) SPECIES - species name

(2) PDI - species distribution along insolation gradient (MJ·m-2·d-1) (SD and N not available; see Ackerly et al. 2002, Oecologia 130:449)

(3) ESPD - early summer predawn water potential (MPa)

(4) ESMD - early summer midday water potential (MPa)

(5) LSPD - late summer predawn water potential (MPa)

(6) LSMD - late summer midday water potential (MPa)

(7) MinWP- minimum midday water potential (MPa), see paper

(8) LogLLS - Log leaf life span (months)

(9) SLA - Specific leaf area (mm2/mg)

(10) Am - Carbon assimilation per unit mass (nmol·g-1·s-1)

(30) VsDm - Vessel Diameter (µm)

(31) LogHeight - log10 plant height (m) (log-transformed prior to calculation of mean, SD; multivariate analyses used a composite measure)

(32) LogSpread - log10 canopy breadth (m) (derived from ancova; see text)

(33) LogStNm - log10 number of stems at 1/10 of maximum height (log-transformed prior to calculation of mean, SD)
