Reproductive Biology of Invertebrates, Progress in Asexual Reproduction

About 95% of all known animal species are invertebrates. Knowledgeof their sexual, reproductive and developmental biology isessential for the effective management of species that areeconomically useful to man, or are harmful to him, his crops orlivestock.

DR. K.G. ADIYODI, formerly Professor of Physiology and Dean,Faculty of Science, Calicut University, Kerala, India andVice-Chancellor, Cochin University of Science and Technology, Kochi, is now Public Service Commissioner to Government of India,New Delhi. A distinguished invertebrate reproductive biologist, whogave the discipline of invertebrate reproductive biology a global distinctiveness and identity of its own, Dr. K.G. Adiyodi is Founder Secretary of the International Society of Inverebrate Reproduction, Founder Editor-in-Chief of the International Journal of Invertebrate Reproduction and Development, and Founder President of the Indian Society of Invertebrate Reproduction.

DR. RITA G. ADIYODI, formerly Rhodes Visiting Fellow, Somerville College, Oxford (1976-78), is Professor of Zoology at CalicutUniversity. She served as President of the Crustacean Reprobiologyand Aquaculture Bureau of India and as Vice-President of the Indian Society of Invertebrate Reproduction. Dr. Rita Adiyodi representedIndia on the International Committee of Comparative Endocrinology.
The Adiyodis have worked extensively, over the past three decades,on the endocrinology and physiology of growth and reproduction ofarthropods, chiefly crustaceans.

DR. ROGER NEVILLE HUGHES is Lloyd Roberts Professor, Professor of Zoology, in the School of Biological Sciences, University of Wales, Bangor. While maintaining wide interest in evolutionary andbehavioural ecology, he has focussed particularly on the biology ofclonal animals. By adopting the bryozoan Celloporela hyalina which can be propogated sexually and asexually, as a model experimentalorganism, he is able to investigate a range of fundamental problems including gender allocation in simultaneous hermaphrodites, theeffect of temperature on body size and the contribution of crypticspeciation to marine diversity.

The story of invertebrate gametes-their structure, origin, composition, physiology, and production mechanisms-was told in Volumes I and II; how accessory sex gland secretions facilitate their packaging, storage, survival, and delivery in Volume III; events leading to and following the union of gametes such as insemination, sperm-egg interaction, fertilization, development, embryonic nutrition, eclosion, and larval settlement and metamorphosis in Volume IV; different aspects of invertebrate sexology such as patterns of sexuality, sex determination, sexual differentiation, and maturation, sexual receptivity and behaviour, and sex changes in Volume V; asexual propogation and regeneration, parthenogenesis, special modes of reproduction such as polyembryony and paedogenesis, fecundity, sterility, breeding cycles, reproductive strategies (life-history tactics), and interspecific reproductive isolation in Volume VI; molecular and other aspects of differentiation and development of selected invertebrate groups in Volume VII; regulation of reproduction in representative acoelomates, pseudocoelomates, and schizocoelomates in Volume VIII; progress in male gamete ultrastructure and phylogeny in Volume IX; progress in developmental endocrinology in Volume X. Volume XI Progress in Asexual Reproduction, records progress in our knowldege on the subject and provides much new information.

About 95 per cent of all known animal species are invertebrates. A knowledge of their sexual, reproductive, and developmental biology is essential for the effective management of species that are economically useful to man or are harmful to him, his crops and livestock. This treatise is the first to cover all aspects of reproduction and development of the entire spectrum of invertebrates terrestrial, marine, fresh-water, brackish-water, free-living, and parasitic. The chapters, by leading world experts in their fields, are up-to-date and informative, and suggest a number of problems for future research. Progress in Asexual Reproduction is the eleventh volume in the series.
