Book Description
The Mollusca, Volume 6: Ecology provides an overview of the state of knowledge in molluscan ecology. It is part of a multivolume treatise that covers the fields of biochemistry, physiology, neurobiology, reproduction and development, evolution, ecology, medical aspects, and structure. The Mollusca is intended to serve a range of disciplines: biological, biochemical, paleontological, and medical. As a source of information on the current status of molluscan research, it should prove useful to researchers of the Mollusca and other phyla, as well as to teachers and qualified graduate students. The book contains 15 chapters, arranged into three levels of ecological perspective: (a) distributional studies; (b) physiological ecology and bioenergetics; and (c) population genetics and dynamics. A discussion of the planetary distribution of and ecological constraints upon the mollusca is followed by separate chapters on the life styles and distribution of mollusks on the deep-sea bottom, in mangroves, and on coral reefs; and the trophic and reproductive ecology of those intrinsically fascinating molluscan groups—the nudibranchs and cephalopods. Subsequent chapters present physiological ecology in land snails and in freshwater bivalves, prosobranchs, and pulmonates, with a survey of the techniques of actuarial bioenergetics as applied to nonmarine molluscs. Other chapters cover population dynamics and biology in an introduced pest species, population genetics of marine molluscs, ecogenetics of land snails, and life-cycle pattems throughout the major molluscan taxa.
Ecological Implications of Minilivestock

Book Description
This book provides stimulating and timely suggestions about expanding the world food supply to include a variety of minilivestock. It suggests a wide variety of small animals as nutritious food. These animals include arthropods (insects, earthworms, snails, frogs), and various rodents. The major advantage of minilivestock is that they do not have t

Molluscs as Crop Pests
Author: G. M. BarkerPublisher: CABI
ISBN: 9780851997902
Category : Technology & Engineering
Languages : en
Pages : 488
Book Description
Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

Book Description
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.
