FIGURE 2. Diversity patterns for ground-dwelling bryophytes: terricolous (•), rupicolous (♦), and humicolous (▪) along an elevational gradient (2150–3050 m a.s.l.). Upper top graph: diversity curves for epiphytic (▵) and ground (▿) bryophyte communities from 350 to 3050 m.
FIGURE 3. (a) Ratios of liverworts to mosses, and (b) specialists to generalists along the upper elevational gradient of Piton des Neiges volcano.
FIGURE 4. Bryophyte growth forms spectra (relative fraction of total reported bryoflora % per elevation) on subalpine habitats of Piton des Neiges volcano.
FIGURE 5. Scatter plots of species richness and elevation against functional richness (FRic) on the upslope of the Piton des Neiges volcano for ground (circles) and epiphytic communities (triangles). Pearson rank's correlation is indicated when relationship is significant (***: p < 0.001, **: p < 0.01, +: p < 0.1) . Marginal trend in FRic against elevation for ground-dwelling communities.
TABLE A1 Data set of 8 traits for 99 bryophyte species: growth form, stem length and stem diameter, presence/absence of secondary pigments, hyaline hairpoint, papillae, lamellae, and dissected leaves.
