Download or read book Evolutionary Developmental Biology of Invertebrates 6 written by Andreas Wanninger and published by Springer. This book was released on 2015-08-11 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-author, six-volume work summarizes our current knowledge on the developmental biology of all major invertebrate animal phyla. The main aspects of cleavage, embryogenesis, organogenesis and gene expression are discussed in an evolutionary framework. Each chapter presents an in-depth yet concise overview of both classical and recent literature, supplemented by numerous color illustrations and micrographs of a given animal group. The largely taxon-based chapters are supplemented by essays on topical aspects relevant to modern-day EvoDevo research such as regeneration, embryos in the fossil record, homology in the age of genomics and the role of EvoDevo in the context of reconstructing evolutionary and phylogenetic scenarios. A list of open questions at the end of each chapter may serve as a source of inspiration for the next generation of EvoDevo scientists. Evolutionary Developmental Biology of Invertebrates is a must-have for any scientist, teacher or student interested in developmental and evolutionary biology as well as in general invertebrate zoology. This chapter is dedicated to the Deuterostomia, comprising the Echinodermata and Hemichordata (usually grouped together as the Ambulacraria) as well as the Cephalochordata and the Tunicata.

Download or read book Chordate Origins and Evolution written by Noriyuki Satoh and published by Academic Press. This book was released on 2016-07-14 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chordate Origins and Evolution: The Molecular Evolutionary Road to Vertebrates focuses on echinoderms (starfish, sea urchins, and others), hemichordates (acorn worms, etc.), cephalochordates (lancelets), urochordates or tunicates (ascidians, larvaceans and others), and vertebrates. In general, evolution of these groups is discussed independently, on a larger scale: ambulacrarians (echi+hemi) and chordates (cephlo+uro+vert). Until now, discussion of these topics has been somewhat fragmented, and this work provides a unified presentation of the essential information. In the more than 150 years since Charles Darwin proposed the concept of the origin of species by means of natural selection, which has profoundly affected all fields of biology and medicine, the evolution of animals (metazoans) has been studied, discussed, and debated extensively. Following many decades of classical comparative morphology and embryology, the 1980s marked a turning point in studies of animal evolution, when molecular biological approaches, including molecular phylogeny (MP), molecular evolutionary developmental biology (evo-devo), and comparative genomics (CG), began to be employed. There are at least five key events in metazoan evolution, which include the origins of 1) diploblastic animals, such as cnidarians; 2) triploblastic animals or bilaterians; 3) protostomes and deuterostomes; 4) chordates, among deuterostomes; and 5) vertebrates, among chordates. The last two have received special attention in relation to evolution of human beings. During the past two decades, great advances have been made in this field, especially in regard to molecular and developmental mechanisms involved in the evolution of chordates. For example, the interpretation of phylogenetic relationships among deuterostomes has drastically changed. In addition, we have now obtained a large quantity of MP, evo-devo, and CG information on the origin and evolution of chordates. - Covers the most significant advances in this field to give readers an understanding of the interesting biological issues involved - Provides a unified presentation of essential information regarding each phylum and an integrative understanding of molecular mechanisms involved in the origin and evolution of chordates - Discusses the evolutionary scenario of chordates based on two major characteristic features of animals—namely modes of feeding (energy sources) and reproduction—as the two main forces driving animal evolution and benefiting dialogue for future studies of animal evolution

Download or read book Advances in Comparative Immunology written by Edwin L. Cooper and published by Springer. This book was released on 2018-08-07 with total page 1063 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunologists, perhaps understandably, most often concentrate on the human immune system, an anthropocentric focus that has resulted in a dearth of information about the immune function of all other species within the animal kingdom. However, knowledge of animal immune function could help not only to better understand human immunology, but perhaps more importantly, it could help to treat and avoid the blights that affect animals, which consequently affect humans. Take for example the mass death of honeybees in recent years – their demise, resulting in much less pollination, poses a serious threat to numerous crops, and thus the food supply. There is a similar disappearance of frogs internationally, signaling ecological problems, among them fungal infections. This book aims to fill this void by describing and discussing what is known about non-human immunology. It covers various major animal phyla, its chapters organized in a progression from the simplest unicellular organisms to the most complex vertebrates, mammals. Chapters are written by experts, covering the latest findings and new research being conducted about each phylum. Edwin L. Cooper is a Distinguished Professor in the Laboratory of Comparative Immunology, Department of Neurobiology at UCLA’s David Geffen School of Medicine.

Download or read book The Sea Urchin Embryo written by G. Czihak and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned investigators. But sea urchin eggs have other, more practical, advantages: they lend themselves to surgical operation without difficulty and they heal perfectly; they can be obtained in very large amounts and represent thus an extremely favorable material for biochemists and molecular embryologists. It is not surprising that, in view of these exceptional advantages, sea urchin eggs have attracted the interest of innumerable biologists since O. HERTWIG discovered the fusion of the pronuclei (amphimixy), in Paracentrotus lividus, almost a century ago. The purpose of the present book is to present, in a complete and orderly fashion, the enormous amount of information which has been gathered, in the course of a hun dred years of sea urchin embryology. JOSEPH NEEDHAM, in 1930, was still able to present all that was known, at that time, on the biochemistry of all possible species of developing eggs and embryos in his famous "Chemical Embryology" (Cambridge University Press) . It would no longer be possible for one man to write a modern version of what was a "Bible" for the young embryologists of forty years ago.

Download or read book Animals and Human Society written by Colin G. Scanes and published by Academic Press. This book was released on 2017-09-18 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals and Human Society provides a solid, scientific, research-based background to advance understanding of how animals impact humans. Animals have had profound effects on people from the earliest times, ranging from zoonotic diseases, to the global impact of livestock, poultry and fish production, to the influences of human-associated animals on the environment (on extinctions, air and water pollution, greenhouse gases, etc.), to the importance of animals in human evolution and hunter -gatherer communities.As a resource for both science and non-science, Animals and Human Society can be used as a text for courses in Animals and Human Society or Animal Science, or as supplemental material for Introduction to Animal Science. It offers foundational background to those who may have little background in animal agriculture and have focused interest on companion animals and horses. The work introduces livestock production (including poultry and aquaculture) but also includes coverage of companion and lab animals. In addition, animal behavior and animal perception are covered.Animals and Human Society is likewise an excellent resource for researchers, academics, or students newly entering a related field or coming from another discipline and needing foundational information, as well as interested laypersons looking to augment their knowledge on the many impacts of animals in human society. - Features research-based and pedagogically sound content, with learning goals and textboxes to provide key information - Challenges readers to consider issues based on facts rather than polemics - Poses ethical questions and raises overall societal impacts - Balances traditional animal science with companion animals, animal biology, zoonotic diseases, animal products, environmental impacts and all aspects of human/animal interaction
