Figure 2. The impact of removing trait information for the rare species on the computation of the functional diversity metric under Scenario 1 (a, d, g, j, m, p), rarity assessed from the full species list across all 24 sites (trait values assumed to be constant across all sites), under Scenario 2 (b, e, h, k, n, q), rarity assessed at the individual site level trait values assumed to vary between sites (i.e. high intraspecific variability) and Scenario 3 (c, f, i, l, o, r), rarity assessed from the full species list across all 24 sites (trait values assumed to be constant across all sites, metrics calculated per quadrat). Data expressed as a proportion of the metric value at the full species complement for (a, b, c) FDis – functional dispersion, (d, e, f) FDiv – functional divergence, (g, h, i) FEve – functional evenness, (j, k, l) FRic – functional richness, (m, n, o) RaoQ – Rao's functional entropy and (p, q, r) LDMC – the community weighed mean of leaf dry matter content. Each line represents one site.
