Estimates of components of variation results of the four-way PERMANOVA on single factors and interaction terms for all analyzed variables.

The components of variation was estimated by PERMANOVA (Euclidean distances, 9999 permutations) for MGT, minimum generation time; MEGD, minimum time until first egg(s) deposition; MEMD, minimum time for embryonic development; MJD, minimum time for the development of juveniles into adults; MALS, minimum adult life span; OS, offspring per female at the end of the experiment. High values correspond to a high relative importance of the respective factor.Abbreviations: S, absence/presence of sulphide; T, temperature (16, 10 and 4°C); Sp, cryptic Halomonhystera disjuncta species GD1–3 (previously named Geomonhystera disjuncta); Sal, salinity (25, 29.5 and 34 psu).Estimates of components of variation results of the four-way PERMANOVA on single factors and interaction terms for all analyzed variables.
