Download or read book The Process of Animal Domestication written by Marcelo Sánchez-Villagra and published by Princeton University Press. This book was released on 2022-01-18 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first modern scholarly synthesis of animal domestication Across the globe and at different times in the past millennia, the evolutionary history of domesticated animals has been greatly affected by the myriad, complex, and diverse interactions humans have had with the animals closest to them. The Process of Animal Domestication presents a broad synthesis of this subject, from the rich biology behind the initial stages of domestication to how the creation of breeds reflects cultural and societal transformations that have impacted the biosphere. Marcelo Sánchez-Villagra draws from a wide range of fields, including evolutionary biology, zooarchaeology, ethnology, genetics, developmental biology, and evolutionary morphology to provide a fresh perspective to this classic topic. Relying on various conceptual and technical tools, he examines the natural history of phenotypes and their developmental origins. He presents case studies involving mammals, birds, fish, and insect species, and he highlights the importance of domestication for the comprehension of evolution, anatomy, ontogeny, and dozens of fundamental biological processes. Bringing together the most current developments, The Process of Animal Domestication will interest a wide range of readers, from evolutionary biologists, developmental biologists, and geneticists to anthropologists and archaeologists.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is the result of a NATO Advanced Study Institute held in England at Kingswood Hall of Residence, Royal Holloway College (London University), Surrey, during the last two weeks of July, 1976. The ASI was organized within the guide lines laid down by the Scientific Affairs Division of the North Atlantic Treaty Organization. During the past two decades, significant advances have been made in our understanding of vertebrate evolution. The purpose of the Institute was to present the current status of our know ledge of vertebrate evolution above the species level. Since the subject matter was obviously too broad to be covered adequately in the limited time available, selected topics, problems, and areas which are applicable to vertebrate zoology as a whole were reviewed. The program was divided into three areas: (1) the theory and methodology of phyletic inference and approaches to the an alysis of macroevolutionary trends as applied to vertebrates; (2) the application of these methodological principles and an alytical processes to different groups and structures, particular ly in anatomy and paleontology; (3) the application of these re sults to classification. The basic principles considered in the first area were outlined in lectures covering the problems of character analysis, functional morphology, karyological evidence, biochemical evidence, morphogenesis, and biogeography.

This book was released on 2013-03-09 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modification of embryonic development by genetic differences in the mother is a well-regcognized phemomenon, but little is known about the genet ics of these maternal traits or the mechanisms by which they act. To illustrate the genetic approach to the problem, examples are given of how differences in embryonic response to a teratogen can be partitioned into those resulting from differences in embryonic genotype (including the possible role of X-linked genes in producing reciprocal cross differences), maternal genotype, and cytoplasmically transmitted factors. The advantages and limitations of analysis by appropriate crosses, in utero treatments, embryo transfers, and in vitro experiments are illustrated. The numerous inbred strains of the mouse, with well-documented physiology, the recently developed recombinant inbred strains, and the existence of easily identified biochemical marker genes offer at tractive opportunities, so far largely unexploited, for causal analysis of mater nal effects on teratological responses. VII. ADDENDUM Since this chapter was written, several relevant papers have appeared. The strain difference between AI] and C57BU6] mice in frequency of cleft-palate response to cortisone was fitted to a model of normally distributed log tolerance (Biddle and Fraser, 1976). Genetic differences, both in maternal uterine environment and embryonic response, can be represented in terms of their effect on the median effective dose required for the cleft-palate re sponse. The maternal effect of AI] dams relative to C57BU6] dams caused a two-fold reduction in embryonic tolerance to cortisone-induced cleft palate.

This book was released on 2012-12-06 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume were presented at an international symposium, held in South Australia on September 8-10, 1983. The purpose of the meeting was to present the comparative physiology of gas exchange, water balance and energet ics of developing vertebrate embryos. contributions were invited from leading research workers in an attempt to represent the forefront of investigation of all vertebrate classes and to promote a broadly comparative approach to the study of embryonic physiology. These proceedings therefore reflect the current level of research activity focus ing on each group of vertebrates. While considerable expansion and specializa tion has occurred in the area of avian embryos over the last decade, work on reptilian embryos is less developed and that on fish and amphibians is still in its infancy. Although a great deal is known about respiration and metabolism in embryos of placental mammals, the physiology associated with the curious mode of development of monotreme and marsupial embryos has not been examined until recently. In this symposium. the well-studied vertebrate classes are repre sented primarily by specific research papers that document original work. These are balanced by more extensive reviews of the lesser known classes.
Download or read book Physiology of the Amphibia Volume 2 written by Lofts and published by Elsevier. This book was released on 2012-12-02 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiology of the Amphibia, Volume II focuses on the various aspects of amphibian reproduction, both physiological and behavioral, and the interrelationship between these mechanisms and the environment. Organized into five chapters, the book begins with the integrative functions of the amphibian brain. It then describes the cytophysiology of the amphibian adenohypophysis, as well as their reproductive organs and associated sexual structures. It also discusses the physiology of the process of yolk formation, vitellogenesis. The reproductive and courtship patterns and intersexuality among amphibians are also described. This book will be useful to general biologists as a reference source and to students with interests in animal physiology.
