DescriptionThe 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
