Fig. 3. The effect of preconditioning at 98% RH (relative humidity) on the levels of trehalose, glucose and glycerol in P. superbus, a `fast dehydration strategist' and five `slow dehydration strategist' strains of Panagrolaimus. Nematodes were exposed to 98% RH for various time periods (0–96 h) before carbohydrates were extracted. Carbohydrate levels are expressed as percentage dry mass. (A) P. superbus DF5050; (B) P. rigidus AF36; (C) Panagrolaimus sp. PS1159; (D) Panagrolaimus sp. PS1579; (E) Panagrolaimus sp. WS94; (F) Panagrolaimus sp. PS443.
