Figure 2 in Tun formation is not a prerequisite for desiccation tolerance in the marine tidal tardigrade Echiniscoides sigismundi

Figure 2. Desiccation tolerance of Echiniscoides sigismundi. Tardigrades were desiccated for a period of 48 hours from seawater (SW) and ultrapurified water (UPW). They were subsequently rehydrated in seawater from the locality and monitored at 5 min, 30 min, 2 h, 24 h, and 48 h post-rehydration. Mean ƚ SEM activity (N = 6) for SW-dehydrated tardigrades: 4 ƚ 2% (5 min post-rehydration); 56 ƚ 13% (30 min post-rehydration); 74 ƚ 9% (2 h post-rehydration); 99 ƚ 1% (24 h post-rehydration); 95 ƚ 2% (48 h post rehydration). Mean ƚ SEM activity (N = 6) for UPW-dehydrated tardigrades: 2 ƚ 2% (5 min post-rehydration); 19 ƚ 4% (30 min post-rehydration); 30 ƚ 4% (2 h post-rehydration); 99 ƚ 1% (24 h post-rehydration); 92 ƚ 3% (48 h post-rehydration). *Significant difference (P ≤ 0.05) between activity of SW- and UPW-desiccated tardigrades, at the given time point.
