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.
