Contours of <i>pe</i>-ratio and <i>z</i>-ratio.

<p>(a) Contours of <i>pe</i>-ratio and (b) <i>z</i>-ratio as functions of SST and NPP/Z_eu and NPP, respectively.</p

Spearman rank-order and Pearson product-moment correlation between fisheries yields and factors for untransformed and transformed data, respectively.

<p>Significant correlations are in bold type, with associated probabilities indicated with “*” for p = 0.05 and “**” for p = 0.01. N = 52 for all correlation coefficients.</p

Fishery yield versus <i>z</i>-ratio and mesozooplankton productivity.

<p>Scattergrams of: (a) total monthly fishery yield and <i>z</i>-ratio; (b) same data as panel (a) transformed to approximate bivariate normality; (c) total monthly fishery yield and mesozooplankton productivity computed using the <i>Eppley</i>-VGPM algorithm; and (d) same data as panel (c) transformed to approximate bivariate normality. N = 52, the total number of LMEs in the analysis, for all plots. r_S = Spearman rank-order correlation and r_P = Pearson product-moment correlation.</p

Results from the PLSR analysis with percentage of fishery yield explained by the first component and correlations between independent variables and the first component axis.
