Evolutionary and Ecological Aspects of Crustacean Diapause: Proceedings of the Symposium 'Diapause in the Crustacea--with Invited Contributions on Non-crustacean Taxa' Held in Gent, August 24-29, 1997Luc Brendonck, Luc Meester, Nelson Hairston (Jr.) Resting stages (diapause) are important for the life cycles of many crustaceans and have played a key role in the adaptive radiation of Brachiopoda, Ostracoda and Copepoda. Dormancy strategies determined by the characteristics of the onset of and the termination of the resting phase have substantial significance for ecological and evolutionary dynamics. The forty-one contributions in this volume stem from the second international symposium 'Diapause in the Crustacea' held in Gent, Belgium August 24-29 1998. |
