Physical factors measured in the Valdivia River estuary during recruitment periods of Cancer edwardsii during the three study years. Flow is a proxy of river discharge, zonal stress is a measure of onshore winds, meridional stress is a measure of alongshore winds, upwelling index is a measure of upwelling intensity based on the differences in temperature between offshore and coastal estimates (see “Methods”), and tidal range is the mean of the daily difference between low and high tide height
