Figure 1. Distinction between range and occupancy, illustrated
with examples from the flora of the British Isles: (a) large range and
high occupancy (Fritillaria meleagris ), (b) small range and high
occupancy (Fumaria occidentalis ), (c) large range and low
occupancy (Maianthemum bifolium ), and (d) small range and low
occupancy (Alchemilla minima ) .
Figure 2. Schematic diagram of the three proposed rarity
dimensions and their relationship to spatial scale.
Figure 3. Hypothesised process–rarity relationships. Solid
arrows indicate a direct relationship between processes (left) and
rarity dimensions (right); dashed arrows indicate an indirect
relationship, as described in-text.
