Table 4.

Discriminant function (DF) loadings for each variable sorted by their importance in discriminating harbour porpoises by sampling group.

Variable	DF1	DF2
δ13C	0.83	-0.12
Cd	-0.59	0.51
δ15N	0.58	-0.01
Hg	0.37	0.92
Se	0.11	0.54
Zn	-0.04	-0.28
Cu	-0.34	0.10
Fe	-0.43	0.10
Eigenvalue	4.6	2.5
% of var.	61	33

Variables and coefficients in bold are those that had the strongest effect on discrimination (r > 0.5). Eigenvalues and the percentage of total variance (% of var.) among groups accounted for by the canonical variables are also given.
