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
