Polyol accumulation in earthworm cocoons induced by dehydration
1995
Holmstrup, M.
Earthworm egg capsules ("cocoons") of five species were shown to accumulate polyol, probably sorbitol, when dehydrated at -3 and 20 degrees C. Low temperature (0 degrees C) did not induce polyol accumulation if cocoons were not dehydrated. The polyol accumulation was restricted to the embryos of the cocoons. Accumulated polyol will reduce water loss of the embryo and thus increase the chances for survival in cocoons exposed to cold or drought.
