Dormancy is a suspension of the vital functions in an organism for sometime very long time to overcome harsh environmental conditions. It is a widespread adaptation in many phyla from bacteria to vertebrates and may exert a great influence at aquatic communities.
Many authors of this new book were participants at the workshop on diapause in aquatic invertebrates (Pallanza, Italy 2003). The book consists of two major parts indicated in its title: Phenomenology of diapause and significance of this adaptation in scientific and practical uses. Cultivation of live food, like rotifers or Artemia is an expanding application of practical use of diapause in modern aquaculture. Diapause provides the advantage of promoting the colonization of new environments by facilitating the passive transport of the resting stages of invasive species. Creation of artificial ecosystems outside the Earth's biosphere with using dormancy becomes an actual possibility with the plans of humans to colonize our nearest planets. Studies on the vertical distribution of resting eggs in sediment cores yield important ecological information.
Properties of diapause and individual peculiarities of this ancient and well-developed adaptive phenomenon are regarded in the evolutionary distant groups like Rotifers, Crustaceans and Insects.
From the reviews: "The best-defined types of dormancy are diapause and quiescence. These two remarkable abilities are discussed in the new book Diapause in Aquatic Invertebrates ! . The book written by 20 authors, examines the current state of knowledge over 14 chapters and two major parts. ! All in all, the book is the best available on the phenomenon of diapause. ! This interesting volume ! has something to say about the nature of life." (Ralph Schill, Lab Times, Issue 2, 2008)
