Adjusted <i>R</i>² values from partitioning of the amount variation explained by depth (D), sea surface temperature (SST), zooplankton volume (Z) and PCNM eigenvectors (space) for intraannual analysis at the CCA and CalCOFI scales in each sample year.

<p>Pure space indicates the fraction of variation explained by the spatial covariates after factoring out the shared variation explained by the environmental covariates. PC axes are extracted from a PCA of the site by species matrix.
