AbstractDesiccation during water recession at oviposition sites can be a major cause of embryo death in clutches of aquatic amphibians. However, aquatic eggs of the north-western salamander, Ambystoma gracile, can survive out of water for at least 30 days in the field. Females lay eggs surrounded by a firm jelly matrix which presumably protects embryos from desiccation. In a field study, embryos from clutches located either in or out of the water showed no differences in size or stage at hatching. In laboratory experiments, where genetic effects were controlled, air exposure had no effect on embryo survival rate, size or stage at hatching. The ability ofA. gracile to survive prolonged droughts or water recession during embryonic development may be shared by other amphibians
