Описание: This volume presents the proceedings of the eighth Colloquium Crustacea Decapoda Mediterranea, which was held at the Ionian University on Corfu Island, Greece, from 2 to 6 September 2002, and reflects recent advances in decapod crustacean research. The meeting is the oldest European carcinological event, organized regularly at 3-year intervals since 1972. Although focused on the Mediterranean Sea, worldwide contributions provided a forum for fruitful contact and scientific exchange. The book covers up-to-date issues in decapod crustacean research, including genetics, morphology, reproduction, ecology, behaviour and fisheries, and it is primarily aimed at scientists interested in decapod crustacean research, but other scientists and decision-makers working on marine ecology and fisheries will also find up-to-date information on relevant issues.

Описание:
Sexual Biology and Reproduction in Crustaceans covers crustacean reproduction as it deals with the structural morphology of the gamete-producing primary sex organs, such as the testis and ovary, the formation and maturation of gametes, their fusion during fertilization, and embryonic development that lead to the release of larvae. Constituting a diverse assemblage of animals, crustaceans are best known by their common representatives, such as shrimps, lobsters, and crabs, but also include many more less familiar, but biologically important forms.
This work covers the variety of ways in which both male and female gametes are produced by evolving different sexual systems in crustaceans, the range of reproductive systems, and the accordingly, and highly diverse, mechanistic modes of sex determination. In addition, the book features such topics as genetic and environmental determinants in sex determination pattern, variability of mechanisms of fertilization among different species, the origin of different mating systems, the associated mating and brooding behaviors, and the adaptive ability to different environmental conditions with discussion on the evolutionary ecology of social and sexual systems in certain species, which have shown eusocial tendencies, similar to social insects.
Marine species occupying diversified ecological niches in tropical and temperate zones reproduce under definitive environmental conditions. Therefore, reproductive ecology of different crustaceans inhabiting different ecological niches also constitutes another important aspect of the work, along with yolk utilization and embryogenesis leading to release of different larval forms, which reflect on their aquatic adaptability.
