Appendix A. Relationship between the number of pollinator groups and the natural log of the number of grid cells occupied by a plant species.

Number of functional groups was independent of the number of grid cells for invasive and casual archaeophytes (straight lines in Fig. A1), and these two types of archaeophytes usually reached the highest numbers of functional pollination groups. Within the range of the examined number of grid cells, invasive archaeophytes reached on average the highest number, about 6.5 pollinator functional groups (the thin straight line in Fig. A1). Casual archaeophytes harboured about 4.7 functional groups (the thick straight line in Fig. A1), which is the second highest value up to 103 grid cells (i.e., 4.6 grid cells on a log scale; the cross of the thick straight line with the thick curve of casual and naturalized neophytes in Fig. A1). Numbers of functional groups for plants with the other status then invasive and casual archaeophytes increased with increasing number of grid cell (curves in Fig. A1). This increase was faster for native species, naturalized archaeophytes and invasive neophytes (thin curve in Fig. A1) than for casual and naturalized neophytes (thick curve in Fig. A1). However, for the casual and naturalized neophytes (thick curve in Fig. A1), nearly within the whole range of the number of grid cells their numbers of functional groups were higher than for native species, naturalized archaeophytes and invasive neophytes (thin curve in Fig. A1; the latter group harboured a higher number of pollinator functional groups only above the cross of the thin and thick curve in Fig. A1).

FIG. A1. Relationship of the number of pollinator groups with ln number of grid cells occupied by a plant species in the Czech Republic, shown for plant status groups defined on the basis of their origin, residence time and invasion status. Note that the model is described using log link function but visualised on counts. For invasive archaeophytes: NUMBER OF POLLINATOR FUNCTIONAL GROUPS = 1.87 (dashes and thin straight line); for casual archaeophytes: NUMBER OF POLLINATOR FUNCTIONAL GROUPS = 1.54 (open circles and thick straight line); for casual and naturalized neophytes: NUMBER OF POLLINATOR FUNCTIONAL GROUPS = 0.88 + 0.14 NUMBER OF GRID CELLS (open diamonds and triangles, respectively, and thick curve line); for native species, naturalized archaeophytes and invasive neophytes: 0.02 + 0.28 NUMBER OF GRID CELLS (full triangles, circles and diamonds, respectively, and thin curve line); F = 41.82; df = 5, 955; P < 0.0001. |
