Interannual variability of marine zooplankton and their environments: Within- and between-region comparisons

► The work highlights the first Global Comparison of Zooplankton Time Series.
► Variation of the peak in abundance is affected by annual temperature anomalies.
► Results show no global-scale synchrony in zooplankton time-series.
► There are spatial autocorrelations over substantial distances (1000–3000 km).
► There remains considerable uncertainty about the relative causes of shifts in distributions.
