Fig. 3: Zooplankton time series and correlations.
From: Anchovy boom and bust linked to trophic shifts in larval diet
a 45-year time series of the average zooplankton biovolume (organisms <5 ml) within the sampling grid (Supplementary Fig. 1) from spring CalCOFI cruises. The 1962-1987 and 2005 boom periods are shaded in blue, and the 1988–2003 bust period is shaded in yellow. Correlation between FCLTrp-Scr and (b) zooplankton biovolume (n = 192), and (c) residuals from the Ala δ15N ~ Glu δ15N relationship as a dimensionless indicator of heterotrophic protists contribution to the food chain (n = 199). Source data are provided as a Source Data file.
