Natural dehydration regimes as prerequisite for the successful induction of anhydrobiosis in the nematode Rotylenchulus reniformis.
Revival from anhydrobiosis has been studied in detail in Philodina roseola, a bdelloid very common worldwide (Jacobs, 1909).
Harrison and Hooper 1963, McKendry 1987), and may be due to survival strategies based on anhydrobiosis, at least in dry conditions (Demeure and Freckman 1981), or because these nematodes could have survived on other resources present in the soil, such as nonliving plant material (see Eriksson 1974, Verdejo-Lucas and Pinochet 1992) or soluble soil C (see Nicholas 1962).
This paradox may be explained in that nematodes can survive extreme desiccation and freezing by entering into anhydrobiosis and cryobiosis (Pickup and Rothery 1991, Wharton and Block 1993) and may live in microsites in the soil where moisture and water-vapor movement is sufficient for activity, but difficult to measure (Freckman and Virginia 1989).
Crowe and his colleagues have been inspired by a zoo of organisms whose ability to enter a dry state of suspended animation and then to be revived by water is called anhydrobiosis.
The technology is based on the molecular principles of anhydrobiosis (life without water) that allows multicellular organisms survive in extreme conditions.
