The table shows rank values assigned to the events coded for heterochrony analysis. Events are ordered by number and sorted into groups as in Table 1 and Table 2. Abbreviations of events are given in brackets. Rank values specify the position of the respective event in the event sequence for each of the investigated species. Rank values range from 1 to 11. Minus signs are given where the respective feature is not present in the species of interest. Non applicable events are marked ‘n.a.’. Abbreviations: A.f. (A. franciscana, Branchiopoda), G.f. (G. falcatus, Stomatopoda), S.i. (S. ingentis, Dendrobranchiata), N.h. (N. heteropoda, Caridea), P.f. (P. fallax forma virginalis, Astacidea), N.i. (N. integer, Mysidacea), P.h. (P. hawaiensis, Amphipoda). Event abbreviations are used as in Table 1.
