We used 1982–1991 as the baseline for the predictions because that was the first decade for which continuous daily observations were available and because based on earlier lower resolution data the water temperature of the Wadden Sea did not have an increasing trend before the 1980s. 3 RESULTS 3.1 Free‐living larval stages We collected 21 egg sacs of M. intestinalis and 27 egg sacs of M. orientalis , resulting in a total number of 48 egg sacs (24 per season), cut into 240 egg sac sections.
