1 Org. Divers. Evol. 3, Electr. Suppl. 6: 1-6 (2003) Gesellschaft für Biologische Systematik Figures I-V and Tables I-III Electr. Suppl. 6. to: Doran, N.E., Balmer, J., Driessen, M., Bashford, R., Grove, S., Richardson, A.M.M., Griggs, J. & Ziegeler, D. (2003): Moving with the times: baseline data to gauge future shifts in vegetation and invertebrate altitudinal assemblages due to environmental change. Org. Divers. Evol. 3(2): Fig. I. Total vascular plant species richness in 0.1 ha plots graphed against the percentage importance value of rainforest species (IVRF). (Total species richness = x IVRF x IVRF squared).

2 2 Fig. II. Total vascular plant species richness in 0.1 ha plots graphed against altitude with a polynomial regression model fitted against the data. (Total species richness = x altitude x altitude squared). Fig. III. Mean vascular plant species richness in 10 by 0.01 ha subplots graphed against the altitude gradient with a polynomial regression model fitted against the data. (Mean species richness = x altitude x altitude squared).

3 3 30 Trees 25 Ferns Herbs 20 Woody non-trees Number of species Altitude (m) Fig. IV. Species richness (0.1 ha plots) of four plant life forms trees, ferns, herbs, and woody non-trees (climbers and shrubs) graphed against the altitudinal gradient.

4 Dissimilarity score m 200m 300m 400m 500m 600m 700m Altitude (m) Dissimilarity score m 900m 1000m 1100m 1200m 1300m Altitude (m) Fig. V. Plot of dissimilarity scores for each pair of altitudinal classes. Fig. Va (top) shows dissimilarity scores for each altitude class between 100 and 700 m and all other altitudes. Fig. Vb (bottom) shows dissimilarity scores for each altitude between 800 and 1300 m and all other altitudes.
