This is the second volume on dormancy in aquatic organisms. The book is divided into three parts whereby the first part is devoted to several groups of aquatic organisms which are under-studied in terms of the dormancy's role in the life cycle. The second part looks at the use of dormancy phenomena in science and potential human applications. Furthermore, part 3 comprises of examples of using modeling in relation to dormancy phenomenon and it opens with a theoretical analysis of studies of biological information, including seasonal information. This work can be used as a text book for students as well as a manual for science and practice purposes in ecology, aquaculture, nature protection and space researches with regards to creating ecological life supporting systems and discovering extraterrestrial life on other planets with harsh environmental conditions.
