Abstract

We tested the effect of several environmental variables on the ability of three bdelloid rotifers (Macrotrachela quadricornifera, Philodina roseola and Adineta oculata) to recover from the anhydrobiotic state. The variables we examined were (1) rate of water evaporation, (2) relative humidity during anhydrobiosis, (3) temperature during anhydrobiosis, (4) duration of anhydrobiosis, and (5) rehydration rate. Our results indicate that bdelloids can regulate to some degree net water balance during onset and termination of anhydrobiosis.
