Fig. 2: Diversity profile curves illustrating mid-intertidal diversity as a function of order q values.

Black dots denote Hill numbers: species richness (q = 0), Shannon diversity (q = 1), and Simpson inverse diversity (q = 2). The slope of the curve reflects community evenness. a Diversity pooled across regions. b–e Diversity within (b) Calvert Island, c Northern Quadra Island, d Southern Quadra Island, and e Baynes Sound. f Venn diagram of taxa unique to each possible comparison. b–e Illustrations depict a species cultivated within each site type (b, c) Butter clams (Saxidomus gigantea), d, e Pacific oysters (Magallana gigas).
