Fig. 5. Scanning electron micrographs of desiccated Panagrolaimus following exposure to dried silica gel (<10% RH; relative humidity) for 48 h. (A) Panagrolaimus superbus DF5050 exposed directly to silica gel without preconditioning; (B) Panagrolaimus sp. PS1159 exposed to silica gel following preconditioning at 98% RH for 72 h; (C) Panagrolaimus sp. BW287 exposed to silica gel following preconditioning at 98% RH for 72 h; (D) Panagrolaimus sp. PS1732 exposed to silica gel following preconditioning at 98% RH for 72 h. Scale bars, 15 µm (A–C), 10 µm (D).
