Coefficients in italics were used in linear regressions to predict StDMC from LDMC in various subsets of herbaceous species for which LDMC values were available in the TRY database. Units for StDMC and LDMC are g g−1, giving SSD estimates in equivalent units of mg mm−3. Note that in Díaz et al.9, the coefficients of the regressions are given for LDMC and StDMC values expressed in mg g−1, yielding SSD estimates in g cm−3.
