DOWNLOAD EBOOKBivalves are key components of recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution.

DOWNLOAD EBOOKMolluscs comprise the second largest phylum of animals (after arthropods), occurring in virtually all habitats. Some are commercially important, a few are pests and some carry diseases, while many non-marine molluscs are threatened by human impacts which have resulted in more extinctions than all tetrapod vertebrates combined. This book and its companion volume provide the first comprehensive account of the Mollusca in decades. Illustrated with hundreds of colour figures, it reviews molluscan biology, genomics, anatomy, physiology, fossil history, phylogeny and classification. This volume includes general chapters drawn from extensive and diverse literature on the anatomy and physiology of their structure, movement, reproduction, feeding, digestion, excretion, respiration, nervous system and sense organs. Other chapters review the natural history (including ecology) of molluscs, their interactions with humans, and assess research on the group. Key features of both volumes: up to date treatment with an extensive bibliography; thoroughly examines the current understanding of molluscan anatomy, physiology and development; reviews fossil history and phylogenetics; overviews ecology and economic values; and summarises research activity and suggests future directions for investigation. Winston F Ponder was a Principal Research Scientist at The Australian Museum in Sydney where he is currently a Research Fellow. He has published extensively over the last 55 years on the systematics, evolution, biology and conservation of marine and freshwater molluscs, as well as supervised post graduate students and run university courses. David R. Lindberg is former Chair of the Department of Integrative Biology, Director of the Museum of Paleontology, and Chair of the Berkeley Natural History Museums, all at the University of California. He has conducted research on the evolutionary history of marine organisms and their habitats on the rocky shores of the Pacific Rim for more than 40 years. The numerous elegant and interpretive illustrations were produced by Juliet Ponder.

DOWNLOAD EBOOKThis volume summarises our present knowledge of inductive interaction during early development of various groups of chordates. Embryonic development is mainly epigenetic, that is, each embryo arises through gradual organisation and emergence of its constituent parts and not by the unfolding of preformed structures. Development as far as the full development of the 'body plan' in the embryo is described. At the beginning of development, there is only very restricted spatial diversity, but as development proceeds the interaction of the different parts leads to ever-increasing spatial complexity of the developing embryo. Interaction starts between the different cell organelles of the oocyte and the, spermatozoon; it continues without interruption between the different parts of the very early embryo and also between the different tissues and organ anlagen of the developing embryo. The new hypothesis as to the nature of the inductive interaction, which is postulated here, is in good agreement with the experimental evidence presented and opens new possibilities for fruitful research into this basic concept of embryonic development.
