Many organisms become inactive or undergo some type of dormancy to survive when the environment is unsuitable for growth and reproduction. For example, microorganisms may transform into or produce spores or cysts (Henis 1987), annual and perennial plants produce seeds with varying periods of dormancy (Meyer and Kitchen 1992), and metazoans may hibernate, estivate, cease development or reproduction, or produce a variety of dormant stages. In freshwater invertebrates, dormant stages include gemmules (sponges), statoblasts (bryozoans), and resting eggs (turbellarians, rotifers, and microcrustaceans) (see Pennak 1989).
