Reproductive Biol Invertebrates V 9 PtA: Progress in Male Gamete Ultrastructure and Phylogeny (Reproductive Biology of Invertebrates) - Tapa dura

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, freshwater, brackish-water, free-living and parasitic. The chapters, by leading world experts in their field, are up-to-date and informative, and suggest a number of problems for future research.

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 behavior, and sex changes in Volume V; asexual progagation 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. Volume IX, "Progress in Male Gamete Ultrastructure and Phylogeny", records progress in our knowledge on the subject and provides much new information.
