Minimum generation time of GD1-3 under changing environmental conditions.

Minimum generation time (mean ± standard deviation) of H. disjuncta cryptic species (GD1-3) in the absence (No S) and presence of sulphide (S) at different temperatures (16, 10 and 4°C) and salinity (25, 29.5 and 34 psu). No results were obtained for GD3 in the presence of sulphide because these nematodes died within the two first minutes after adding Su. The minimum generation time was depicted from the day we observed the first adult.Abbreviations: No S, absence of sulphide; S, presence sulphide; GD1-3, cryptic Halomonhystera disjuncta species 1–3 (previously named Geomonhystera disjuncta).Minimum generation time of GD1-3 under changing environmental conditions.
