Cross-correlations between animal counts and environmental parameters.
Analyses used to assess the presence of temporal lag in the response of animal behavior to environmental fluctuations; a) and b) A. fimbria and flow magnitude in June and July respectively, c) E. stoutii and chlorophyll concentration in December and finally, d) juvenile crabs and oxygen concentration in December. “Cross-Correlation Function, (CCF)” is the measure of the power of the statistic. The dashed blue lines represent a CCF significance for α = 0.05 (critical values: ±1.96/√n = approx. ±0.36 in a, and ±0.35 in b, c and d, where n is the sample size). The dashed red lines represent a CCF significance for α = 0.1 (accordingly, critical values: ±1.65/√n = approx. ±0.3 in all four plates).
