Systematics has developed rapidly during the past two decades. A multitude of new methods and contributions from a diversity of biological fields including molecular genetics and developmental biology have provided a wealth of phylogenetic hypotheses, some confirming traditional views others contradicting them. Despite such inconsistencies, it is now possible to recognize robust regions of a 'tree of life' and also to identify problematic areas which have yet to be resolved. This is the first book to apply the current state of phylogeny to an evolutionary interpretation of animal organ systems and body architecture, providing alternative theories in those cases of continuing controversy. Organs do not appear suddenly during evolution; instead they are composed of far simpler structures. In some cases it is even possible to trace particular molecules or physiological pathways as far back as pre-animal history. What emerges is a fascinating picture, showing how animals have combined ancestral and new elements in novel ways to form constantly changing responses to environmental requirements. The Evolution of Organ Systems starts with a general overview of current animal phylogeny, followed by review of general body organization including symmetry, anteroposterior axis, dorsoventral axis, germ layers, segmentation, and skeletons. Subsequent chapters then provide a detailed description of the individual organ systems themselves - integument, musculature, nervous system, sensory organs, body cavities, excretory system, circulatory system, respiratory system, intestinal system, gonads and gametes. Generously illustrated throughout, this accessible text is suitable for both upper level undergraduate and graduate students taking courses in animal evolution, organogenesis, animal anatomy, zoology and systematics. It will also be a valuable reference tool for those professional researchers in these fields requiring an authoritative, balanced and up-to-date overview of the topic.
Volumes 5A and 5B of Fundamentals of Medical Cell Biology are a treatment of several key subjects, including cellular signaling. One profitable way to tackle both volumes is to read them with care but without endeavouring to master most of the details. Then should follow a more plodding study, chapter by chapter. Such a strategy is also urged in respect of the preceding volumes. Although each chapter is only as detailed as space permits, it should in the case of the student serve as an incentive to the study of the original papers.
This volume reviews virtually everything that is known about cell motility and behavior in Chlamydomonas. World experts in each area focus on mitosis and cytokinesis; flagellar assembly and motility; intraflagellar transport, and more will use this reference as a guide for understanding human diseases of the cilium. The volume is richly illustrated and is supplemented by a Website containing both classic and previously unpublished videos of cell motility in Chlamydomonas. Because Chlamydomonas has been the premier model for investigating the function and behavior of cilia and flagella, the chapters summarize the current state of knowledge in these areas as it applies to all ciliated organisms. Thus, this volume will be an essential source for all students and researchers interested in cell motility. This volume is part of a 3-Volume Set (ISBN: 978-0-12-370873-1) and is also sold individually. - Includes a table listing the known proteins (with NCBI accession numbers) for each structure discussed, and the known mutations that affect each structure and process - Essential reference to a model species for the study of mechanisms of motility in free living cells - Includes methods for Chlamydomonas motility research - Companion Website with videos illustrates the marvels of the Chlamydomonas flagella in action
Originally published in 2006, this is a comprehensive and definitive account of the human male gamete. The volume summarizes many unique and revealing characteristics of the sperm cell. It provides a detailed overview of human sperm production, maturation and function, and looks at how these processes affect and influence fertility, infertility and ART. The volume thus provides a detailed review of the most important research and developments, augmented with pertinent references. This book will appeal to all practitioners and scientists in reproductive medicine and in particular to clinical scientists, graduate and post-graduate scientists, and laboratory personnel.
Volume 34 continues the series' tradition of timely review and incisive analyses of key research in developmental biology. Not only valuable to researchers at the forefront of animal and plant development, this volume is also a friendly introduction to students and professionals who are curious about current topics in cellular and molecular mechanisms in development.
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
Aspects of reproduction covered in this volume include classification and phylogeny as revealed by molecular biology; anatomy of the male reproductive tract and organs; anatomy and evolution of copulatory structures; development and anatomy of the female reproductive tract; endocrinology of reproduction; ovarian dynamics and follicle development; s
Apart from malaria, schistosomiasis is the most prevalent parasitic infection in the world. It affects more than 200 million people in 76 tropical and subtropical countries, causing great suffering and resulting in thousands of deaths. Written by world authorities, this book examines many aspects of the biology, pathology, and control of the schistosoma parasite. Ranging in topic from infection in Pharaonic Egypt, through DNA relationships and biological systems, to advances in development of vaccines against the parasite, this book is a comprehensive text written for researchers and medical professionals alike.
