Table 1. Inter- and intra-annual population synchrony between estuaries.

Cross correlation coefficients (r) of peak synchrony measured within 0–3 month lags between estuaries for a) inter-annual density, b) inter-annual biomass, c) intra-annual density, and d) intra-annual biomass. Significant correlations are in bold and the peak lag time in months is reported in parentheses.
