Focuses on the ability crustaceans share with a wide range of invertebrates, to lay eggs that can survive for years without any apparent metabolism in a dry condition, then rapidly develop when water finally comes, and lay another generation of resting eggs. The 26 papers cover the evolutionary aspects, the physiology, induction and termination, the nature of resting stages and their role in the population dynamics of marine and freshwater crustaceans, and crustacean life histories. Specific topics include micro- and macro-evolutionary patterns and processes influencing the distribution of crustacean diapause, the variation in torpidity of diapause in freshwater cyclopoid copepods, the significance of photoperiodism and diapause control in the multicycle Crustacean Daphnia pulex Leydig, the role of parthenogenetic natality and emergence from diapausing eggs in the dynamics of some rotifer populations, and the role of food availability in the variable life history of a cyclopoid copepod.
