Linear discriminant function analysis based on δ¹³C_EAA values of training data comprising of bacteria, fungi and marine phytoplankton (Larsen et al., 2013) and consumers from this study. The phytoplankton comprise of eight diatom samples (D1‐D5; N1‐N3), four chrysophytes (X1‐X4), four haptophytes (H1 – H4), two chlorophytes (K1 & K2), and one cryptophyte (Y1)— see Larsen et al. (2013) for sample codes. The ellipses represent 95% confidence intervals of each endmember, and the arrows represent the relative weightings of the independent variables for creating the discriminant function. Amino acid abbreviations: isoleucine (Ile), leucine (Leu), lysine (Lys), phenylalanine (Phe), threonine (Thr), and valine (Val)
