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)
