Figure 2. MDS relationship between assemblage, loch, distance-code and shell-hash content (bubble size).

Note: a single ordination was first obtained which split the Sites into two distinct groups: (A) Creran and Spelve and (B) Etive and Leven which were analysed as MDS subsets. Bubble size indicates hash content (in g per grab), Code: C – Creran, E – Etive, L – Leven, S – Spelve, 1^st number is the site (e.g. C1 is Creran 1 except for Leven where there was only one site), the second number is the distance code (1 is the closest to the mussel line; see methods). Note that the bubble scaling differs between the figures.
