Available in PDF, EPUB and Kindle. Book excerpt: Invertebrate Embryology and Reproduction deals with the practical and theoretical objectives of the descriptive embryology of invertebrates, along with discussions on reproduction in these groups of animals. It explains several morphological and anatomical expressions in the field and covers the embryology of invertebrate animals, starting from the Protozoa, to the Echinodermata, the Protochordate and Tunicates. These groups include economically important aquatic invertebrates, such as crustaceans, as well as medically important invertebrates and economic arthropods. Each chapter is preceded by the taxonomy of the discussed phylum and/or the species to enable the reader to locate the systematic position. - Covers phylum definition, general characteristics, classification, reproduction, agametic reproduction, gametic reproduction, spawning, fertilization, development and embryogenesis - Includes recent findings in the area, along with detailed figures and photos that illustrate important concepts - Brings together difficult-to-obtain research data from the field, not only in Egyptian libraries, but globally, and previously only found through specialized references not widely available - Clarifies descriptions with striking photos and electron microscopical studies of different species

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Animal Evolution Interrelationships of the Living Phyla written by Claus Nielsen and published by OUP Oxford. This book was released on 2001-03-08 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Evolution is a complete analysis of the evolutionary interrelationships and myriad diversity of the animal kingdom. Using modern phylogenetic reasoning based on characters from an extensive review of morphology, including ultrastructure, and embryology, each phylum is analysed to ascertain its monophyly and hence its ancestral characters. These ancestral characters are then used to construct a complete phylogenetic tree of the extant animal phyla. This new edition of Animal Evolution brings the subject fully up to date including some new ideas and emphases, as well as new bibliographic data. It also includes new chapters on the use of computer programmes and on the use of the new molecular techniques to create phylogenies, both techniques that have grown in prevalence in the field since the first edition was published. Illustrated throughout with finely detailed line drawings and clear diagrams. From reviews of the first edition of Animal Evolution: 'A clear and engaging style exemplified by a series of superbly concise descriptions of the phyla.... These are complemented by excellent illustrations.... The volume belongs on every biologist's bookshelf.' Simon Conway- Morris, Nature 'Texts like these constitute the very cream of taxonomic literature.... It really is a joy to read... and in my opinion it constitutes a highly recommended book for all zoologists. I think it is also particularly suited for seminars on animal classification for both undergraduate and graduate students.' JC von Vaupel Klein, Crustaceana 'I highly recommend this book as a fascinating theory of animal relationships, and an excellent summary of the phylogenetically informative aspects of the biology of the whole animal kingdom.' Maximilian J Telford, Systematic Entomology
