Conceptual diagram for Caucahué channel integrating the results obtained during the zooplankton sampling period (12 h, June 19). Black arrows = counterclockwise tidal excursion. Red arrows: southward residual flow. a and b show the ratios Ladv and Lexc estimated according to Sobarzo et al. (2018) [20], indicating the net southward transport between the sections of the channel and also the speed recorded for the ebb and flood phases in the neap and spring fortnightly periods estimated in this study. Color circles in (c) represent conceptually the different species of the zooplankton community and their relative abundances. Yellow arrows indicate the biological-environmental relationships in the water column. d shows the studied environmental variables in both sections of the Caucahué channel and how they differ on June 19, indicated by the direction of the arrow (see also DistLM analysis)
