Figure 1. Elevational changes in the alpha diversity of plant groups in the Yatsugatake Mountains in central Japan: (a) total, (b) trees, (c) shrubs, (d) herbs, (e) ferns, and (f) bryophytes. The calculated alpha diversity based on the mid-domain effect is denoted by an asterisk (*). In illustrating the alpha diversity, generalised linear models were used to explore the pertinent changes with elevation. When the coefficient was significant, a regression curve was added to the illustration, and a 95% confidence interval was calculated and coloured.
Figure 2. Elevational changes in the beta diversity (βsin indices) of plant groups in the Yatsugatake Mountains in central Japan: (a) total, (b) trees, (c) shrubs, (d) herbs, (e) ferns, and (f) bryophytes.
Figure 3. Elevational changes in the dominance of plant functional types in the Yatsugatake Mountains of central Japan: (a) evergreen trees, (b) evergreen shrubs, (c) graminoids, (d) liverworts.
Figure 4. Elevational changes in the distribution range of plant groups in the Yatsugatake Mountains in central Japan: (a) total, (b) trees, (c) shrubs, (d) herbs, (e) ferns, and (f) bryophytes.
