Download or read book Reproduction written by A. S. Tompa and published by Elsevier. This book was released on 2013-10-22 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mollusca, Volume 7: Reproduction presents the significant features of reproduction for one of the significant major molluscan groups. This book reviews the reproductive biology of land snails, which offers the basis for making fascinating comparisons with other terrestrial groups in illustrating how evolutionary various groups solved their common problem of laying eggs. Organized into six chapters, this volume begins with an overview of the reproductive biology of prosobrach gastropods. This text then provides a comparative morphology of land snail reproductive anatomy. Other chapters consider the endocrine control of the female reproductive activity of Lymnaea stagnalis. This book discusses as well the transition in intraspecific and interspecific sexuality. The final chapter deals with cephalopod reproductive biology. This book is a valuable resource for readers who are in need of more appropriate animal systems for solving research problems pertaining to general reproduction, cytology, sex determination, biochemistry, gamete biology, neuroendocrinology, and evolutionary biology.

Download or read book Oceanography and Marine Biology An Annual Review written by Alan Ansell and published by CRC Press. This book was released on 1999-11-25 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanography and Marine Biology: an Annual Review considers basic areas of marine research, returning to them when appropriate in future volumes, and deals with subjects of special and topical importance in the field of marine biology. The thirty-seventh volume follows closely the objectives and style of the earlier well received volumes, continuing to regard marine sciences - with all their various aspects - as a unit. Physical, chemical and biological aspects of marine science are dealt with by experts actively engaged in their own field. The series is an essential reference text for research workers and students in all fields of marine science and related subjects, and is consistently among the highest ranking impact factors for the marine biology category of the citation indices compiled by the Institute for Scientific Education.

Download or read book Evolutionary Ecology of Freshwater Animals written by B. Streit and published by Birkhäuser. This book was released on 2013-03-11 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary ecology includes aspects of community structure, trophic interactions, life-history tactics, and reproductive modes, analyzed from an evolutionary perspective. Freshwater environments often impose spatial structure on populations, e.g. within large lakes or among habitat patches, facilitating genetic and phenotypic divergence. Traditionally, freshwater systems have featured prominently in ecological research and population biology. This book brings together information on diverse freshwater taxa, with a mix of critical review, synthesis, and case studies. Using examples from bryozoans, rotifers, cladocerans, molluscs, teleosts and others, the authors cover current conceptual issues of evolutionary ecology in considerable depth. The book can serve as a source of critically evaluated ideas, detailed case studies, and open problems in the field of evolutionary ecology. It is recommended for students and researchers in ecology, limnology, population biology, and evolutionary biology.

Download or read book The Lymnaeidae written by Maxim V. Vinarski and published by Springer Nature. This book was released on 2023-11-29 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lymnaeidae (also known as ‘pond snails’) are a species-rich and globally distributed family of freshwater snails, many species of which are known to be hosts of parasitic trematodes (such as the liver fluke, Fasciola hepatica). Written by world-leading experts in the field, this book covers a wealth of topics ranging from the phylogeny and taxonomy of lymnaeid snails to their relationships with helminths and their impact on public and veterinary health. It provides an overview of the species richness, evolution, ecology, biogeography and fossil record of the family. A considerable number of chapters are devoted to the economic and medical importance of lymnaeids, their involvement in the transmission of fascioliasis and other zoonotic diseases. Special chapters deal with the molecular and morphological identification of the Lymnaeidae, their rearing in the laboratory and experimental approaches to their study. This contributed volume is aimed at experts and practitioners in various disciplines: Invertebrate zoology, evolutionary biology, biogeography, aquatic ecology, parasitology, epidemiology and public health. It is also useful for university lecturers, undergraduate and postgraduate students.
Download or read book Mollusca written by Marcel Florkin and published by Elsevier. This book was released on 2014-04-11 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Zoology, Volume VII, Mollusca, provides zoologists and chemists with an overview of the state of knowledge in chemistry and zoology and an introduction to the existing literature. The treatise is arranged by phyla, an arrangement which seemed most suitable for presenting chemical information of zoological significance and for bringing to the attention of chemists those aspects of biochemical diversity of greatest potential interest. Each section, dealing with a major phylum, is introduced by a discussion of the biology and systematics of the group. This is followed by chapters dealing with various aspects of the biochemistry of the group. This volume contains 14 chapters and begins with a discussion of the molluscan framework. This is followed by separate chapters on shell structure and formation, respiratory proteins, and nitrogen metabolism in molluscs. Subsequent chapters deal with molluscan byssus fibers, chemical embryology, pigments, carbohydrate metabolism, lipid metabolism and distribution, endocrinology, anisosmotic and isosmotic cellular regulation, pharmacology, and biochemical ecology.
