Evolution of Sexual Reproduction in Marine Invertebrates available in PDF, EPUB and Kindle. Three major aspects that distinguish this book are that (1) it contains the most detailed analysis of the sexual reproduction (oogenesis, fertilization and embryonic incubation) in a particular phylum of the aquatic invertebrates (Bryozoa) ever made; this analysis is based on an exhaustive review of the literature on that topic published over the last 260 years, as well as extensive original histological, anatomical and morphological data obtained during studies of both extant and extinct species; (2) this broad analysis has made it possible to reconstruct the major patterns, stages and trends in the evolution of sexual reproduction in various bryozoan clades, showing numerous examples of parallelisms during transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic development are discussed in detail; and (3) the key evolutionary novelties acquired by Bryozoa are compared with similar innovations that have evolved in other groups of marine invertebrates, showing the general trends in the evolution of their sexual reproduction. Ecological background of these innovations is considered too. Altogether these aspects make the monograph an “Encyclopedia of bryozoan sexual reproduction,” offering an integral picture of the evolution of this complex phenomenon.

Acoelomate and Pseudocoelomate Metazoans available in PDF, EPUB and Kindle. Reproduction of Marine Invertebrates, Volume I: Acoelomate and Pseudocoelomate Metazoans is a collection of papers that deals with the evolution of reproductive mechanisms and behavior in marine invertebrates. This collection starts with terminologies and basic events in marine invertebrate reproduction, including the method of estimating sexual reproductive activity, as well as the timing and patterns involved. The book notes that temperatures, salinities, or food availability should be favorable when the young are produced and when they are developing. One paper shows that the reproductive rhythm is dynamic and in some species is latitude-dependent. Other papers discuss the reproductive cycles of different marine invertebrates such as the Porifera, Cnidaria, Nemertinea, and Nematoda. These papers include topics on asexual reproduction, regeneration, sexual reproduction, and development, and then explain in detail the development of certain invertebrates from their kinorhynchs state (embryonic), to the molting stages, juvenile stages, then to adulthood. This book can be useful for marine biologists, marine ecologists, and students involved in marine biological and physical sciences.

Reproduction of Marine Invertebrates Volume V, Molluscs: Pelecypods and Lesser Classes presents valuable insights on the early evolution of molluscan reproductive biology. It discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of pelecypods and the remaining smaller classes, including aplacophora, polyplacophora, and monoplacophora. One chapter in this volume provides a broad overview of the knowledge and problems on oyster reproductive biology. This book is ideal for marine biologists and researchers, reproductive biologists, and developmental biologists.

Download and read online ebook Reproduction and Development of Marine Invertebrates write by W. Herbert Wilson (Jr.). This book was released on 1994. Reproduction and Development of Marine Invertebrates available in PDF, EPUB and Kindle. In Reproduction and Development of Marine Invertebrates a group of internationally recognized researchers assesses the state of current knowledge in the field and identifies future avenues of research. Comprehensive in scope, the book treats all levels of biological organization, from the molecular level to communities of organisms. After a brief historical overview that identifies the conceptual underpinnings of twentieth-century invertebrate zoology and embryology, the book is organized by developmental stages. The authors first present chapters on oogenesis, spermatogenesis, fertilization, and embryonic development. A subsequent section--arranged phylogenetically to encompass annelids, priapulans, molluscs, bryozoans, and echinoderms--covers larval morphology and evolution. The final section treats larval or adult populations and includes new information on the role of hydrodynamics to aid in the understanding of larval dispersal and settlement. Reproduction and Development of Marine Invertebrates is the first book of its kind to be published since 1978. Extensivelyillustrated with more than a hundred line drawings and photos--including sixty high-resolution electron micrographs--it will be of interest to professionals and students in evolutionary biology, invertebrate zoology, developmental biology, and functional morphology.

Reproduction of Marine Invertebrates, Volume III: Annelids and Echiurans illustrates the importance of annelids and echiurans in the evolution of reproductive mechanisms and in the ecology of the sea. It discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of specific annelids, such as polychaeta and clitellata, and of echiurans. The annelids appear to be midway forms in the evolutionary progression of the metazoans. The echiurans, with close affinities to the annelids, are organisms that have become increasingly important for researches in developmental biology. The book will be helpful to marine scientists and biologists, reproduction researchers, and developmental biologists.
