Download or read book Interrelationships of the Platyhelminthes written by D T J Littlewood and published by CRC Press. This book was released on 2000-12-07 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phylum Platyhelminthes is comprised of some 50,000 species of flatworms living in a wide variety of habitats - from the deep sea to the damp soil of tropical forests- where they occupy pivotal roles in many ecosystems. The parasitic forms include tapeworms and flukes, which plague virtually every species of vertebrates and impose major medical, veterinary, and economic burdens. Interrelationships of the Platyhelminthes elucidates the role of flatworms in the animal kingdom. It brings together results from an international group of experts, spanning many disciplines, who give evidence for the phylogeny of the flatworms and constituent major taxa. A combined approach, using traditional comparative techniques along with the modern techniques of molecular phylogeny, is utilized to show that the monophyly of the phylum is not fully established, and that the phylum may in fact consist of two groups: the acoels and their direct relatives, which are basal metazoans, and the Rhabditophora, which is a more derived group. The authors review the contributions of neurobiology, morphology, and developmental and molecular biology in light of their contributions to flatworm phylogenetics. This volume provides explicit and fully defined character matrices wherever possible allowing critics, supporters, and future workers to evaluate the state of flatworms systematics and phylogenetics from a single resource. This volume will appeal to all who have an interest in flatworms and recognize the value of phylogenetics as the basis for comparative biology.

Download or read book The Nervous Systems of Invertebrates An Evolutionary and Comparative Approach written by O. Breidbach and published by Birkhäuser. This book was released on 2013-03-07 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume outstanding specialists review the state of the art in nervous system research for all main invertebrate groups. They provide a comprehensive up-to-date analysis important for everyone working on neuronal aspects of single groups, as well as taking into account the phylogenesis of invertebrates. The articles report on recently gained knowledge about diversification in the invertebrate nervous systems, and demonstrate the analytical power of a comparative approach. Novel techniques in molecular and developmental biology are creating new perspectives that point toward a theoretical foundation for a modern organismic biology. The comparative approach, as documented here, will engage the interest of anyone challenged by the problem of structural diversification in biology.
Download or read book Perspectives in Zoology written by Alan Boyden and published by Elsevier. This book was released on 2013-10-22 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Zoology tries to discuss in a critical way some of the aspects of biology that lack perspective. The book also calls into attention the possibilities of obtaining a more correct view and challenges views that already have already been accepted by the scientific community. In this thought-provoking book, many questions are raised and different viewpoints and their implications are considered in the areas of natural history. Coverage includes the great ages of evolution; the primitive evolution in the eumatozoa; the morphological comparisons between homology and analogy; systematic serology and its principles; and the relationship of systemics, evolution, and phylogeny. The text is recommended for students and professors that deal with biology, zoology, genetics, and evolution who not only wish to explore and understand other approaches to popular theories in zoology, but also wish to be more familiarized and delve deeper with the common yet frequently discussed and debated topics in the field.
Download or read book Gene Activity in Early Development written by Eric H. Davidson and published by Academic Press. This book was released on 2014-06-28 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene Activity in Early Development reviews the state of knowledge regarding genomic function in the programming and operation of what Bonnet, in 1762, described as "the miracle of epigenesis." The book is divided into four sections. Section I is concerned with gene activity in early embryogenesis, with the time of onset and the nature of embryo genome control, and with recent attempts to analyze the shifting patterns of gene expression as development proceeds. Section II reviews various classic and recent studies relevant to the phenomenon of cytoplasmic localization of morphogenetic potential and discusses the significance, from a contemporary vantage point, of this often neglected area of developmental biology. Section III deals with genomic function in oogenesis, beginning with a general survey of what could be described loosely as the natural history of the oocyte nucleus, and proceeding to current attempts to understand the character and the ultimate function of the oocyte gene products. Section IV discusses various aspects of the general problem of gene regulation in animal cells.
Download or read book Invertebrate Pathology Noncommunicable Diseases written by Albert Sparks and published by Elsevier. This book was released on 2012-12-02 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invertebrate Pathology Noncommunicable Diseases discusses the taxonomic and phylogenetic aspects of invertebrate pathology, beginning with protozoans and progressing through the ascending taxonomic order to the chordates. The book is organized into seven chapters that cover the death and postmortem change; reaction to injury and wound repair; the physical and chemical injuries; the effects of venoms and biotoxins; the effects of ionizing radiation; and tumors and tumor-like growths. The opening chapter describes stages of events in death: necrosis; somatic death; gross and histological postmortem changes; and cellular depression and degeneration. The following chapter discusses the inflammatory response, called wound repair, to injury in invertebrates. This text describes the processes that occur after injury in many invertebrates and covers the general principles of physical, chemical, and biological injuries. Discussions on the effects of trauma, pressure and temperature changes, poisons, pesticides, detergents, venoms, biotoxins, and toxigenic algae are included. The book further examines the effects of ionizing radiation both on vertebrates and invertebrates, such as beta particles, gamma and X-rays, and neutrons. The concluding chapter describes the structures of tumor in invertebrates, focusing on hyperplasia or unusual proliferation of typical cellular components, in response to injury or parasitic invasion. With an ultimate objective to stimulate an acceleration of research effort in invertebrate pathology, the book is an invaluable source for invertebrate pathologists, immunologists, and parasitologists.
Download or read book Parasitic Worms Of Fish written by Hartford Williams and published by CRC Press. This book was released on 1994-01-14 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish are a unique group which harbour some 30,000 species of helminths that do not occur in other vertebrates. This book deals specifically with parasitic worms of fish. It covers every aspect of their biology including identification, life-cycles, hostparasite relationships and ecology. It discusses approaches to studying parasitic worm infections, preference of species for particular host species, preference for dwelling in certain organs and tissues, biogeography, seasonality of infections and how parasites have evolved in parallel with their hosts. The book concludes with discussions of fish worms causing diseases in nature and in fish-farms.
