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.

This twenty-two volume set presents the appearance and behavior of thousands of species of animals along with species population and prospects for survival in a arranged alphabetically and easy-to-read format.

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.

This book deals with the ecology of rivers and streams in the Oriental Region, and describes the composition of their unique fauna - especially the diverse array of animals which live on and among the bottom sediments. Dichotomous keys are provided as an aid to the identification of these animals, and the book is illustrated by over 100 pages of line drawings and maps. Special emphasis is given to the impact of human activities on streams and rivers, and the book concludes with a discussion of conservation and management options for these endangered habitats.

"Zoological Record is published annually in separate sections. The first of these is Comprehensive Zoology, followed by sections recording a year's literature relating to a Phylum or Class of the Animal Kingdom. The final section contains the new genera and subgenera indexed in the volume." Each section of a volume lists the sections of that volume.
