This book was released on 2010-03-27 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.

Download or read book Evolutionary Ecology of Social and Sexual Systems written by J. Emmett Duffy and published by Oxford University Press. This book was released on 2007-09-06 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of animal social and sexual evolution has seen a renaissance in recent years with discoveries of frequent infidelity in apparently monogamous species, the importance of sperm competition, active female mate choice, and eusocial behavior in animals outside the traditional social insect groups. Each of these findings has raised new questions, and suggested new answers, about the evolution of behavioral interactions among animals. This volume synthesizes recent research on the sexual and social biology of the Crustacea, one of the dominant invertebrate groups on earth. Its staggering diversity includes ecologically important inhabitants of nearly every environment from deep-sea trenches, through headwater streams, to desert soils. The wide range of crustacean phenotypes and environments is accompanied by a comparable diversity of behavioral and social systems, including the elaborate courtship and wildly exaggerated morphologies of fiddler crabs, the mysterious queuing behavior of migrating spiny lobsters, and even eusociality in coral-reef shrimps. This diversity makes crustaceans particularly valuable for exploring the comparative evolution of sexual and social systems. Despite exciting recent advances, however, general recognition of the value of Crustacea as models has lagged behind that of the better studied insects and vertebrates. This book synthesizes the state of the field in crustacean behavior and sociobiology and places it in a conceptually based, comparative framework that will be valuable to active researchers and students in animal behavior, ecology, and evolutionary biology. It brings together a group of internationally recognized and rising experts in fields related to crustacean behavioral ecology, ranging from physiology and functional morphology, through mating and social behavior, to ecology and phylogeny. Each chapter makes connections to other, non-crustacean taxa, and the volume closes with a summary section that synthesizes the contributions, discusses anthropogenic impacts, highlights unanswered questions, and provides a vision for profitable future research.

Download or read book Stress and Orality written by Francis Hartmann and published by Springer Science & Business Media. This book was released on 2013-08-23 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The reading of STRESS and ORALITY written by F. HARTMANN and G. CUCCHI led me to believe that we should consider the problem of certain migraines, neck pain, fibromyalgia, and chronic fatigue from a radically different angle than the historically traditional approach.” Pr Roger Guillemin (Nobel Laureate in Medicine) Are oral disorders only an issue for dentists? The answer is no. If your patients complain of pain and/or discomfort, if some are diagnosed as suffering from migraines, fibromyalgia or chronic fatigue, and if classical therapies have remained ineffective, this book could help in your daily practice. When it comes to the complex pathology called Temporo-Mandibular Disorders (TMD) most specialists favour a multidisciplinary approach and treatment of socio-psycho-emotional factors as well as dental, lingual or postural disorders. Yet little is known - from a clinical point of view - about a tricky oral spastic habit called severe teeth clenching. In view of the lack of clinical findings from classical investigations on the subject, it could be considered as the “hidden part of an oral parafunctional iceberg”. Neuroscience has been able to shed some light on the multiple connections between trigeminal and non-trigeminal nervous centres, which confirms the significant involvement of the stomatognathic system and trigeminal nerves (V) in both oral as well as non-oral major functions such as eating, breathing, speaking, hearing, and standing ... and also confirms the extensive participation of the paired Vs in the human adaptation process. Too many physicians are still reluctant to admit the pathological responsibilities of the Vs. Therefore their role remains largely underestimated by clinicians. Stress conditions in introverted people cause a parafunctional habit (i.e. severe clenching), which in turn produces trigeminal overstimulation and nociception. Through a process of sensitization this can perturb some non-trigeminal nervous areas, such as the vestibular nuclei and cerebellum (involved in equilibrium). Would you then be willing to accept the possibility that a stressed and introverted patient who clenches hard, durably or frequently may end up suffering from dizziness? If not, this book is not for you. But if you accept the scientific data and clinical facts this book will offer a concrete therapeutic protocol: the Relaxing and Moderating Treatment (RMT), which can greatly help you to familiarize yourself with and neutralize this little known deleterious spastic oral parafunction and its many disconcerting pain-causing and dysfunctional clinical effects. Prepare to be amazed by the results, just as we were!

Download or read book The Sixth Extinction written by Richard E. Leakey and published by Anchor. This book was released on 1996-10-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Richard Leakey, One Of The World's Foremost Experts On Man's Evolutionary Past, Now Turns His Eye To The Future And Doesn't Like What He Sees. To the philosophical the earth is eternal, while the human race -- presumptive keeper of the world's history -- is a mere speck in the rich stream of life. It is known that nothing upon Earth is forever; geography, climate, and plant and animal life are all subject to radical change. On five occasions in the past, catastrophic natural events have caused mass extinctions on Earth. But today humans stand alone, in dubious distinction, among Earth's species: Homo Sapiens possesses the ability to destroy entire species at will, to trigger the sixth extinction in the history of life. In The Sixth Extinction, Richard Leakey and Roger Lewin consider how the grand sprawl of human life is inexorably wreaking havoc around the world. The authors of Origins and Origins Reconsidered, unimpeachable authorities on the human fossil record, turn their attention to the most uncharted anthropological territory of all: the future, and man's role in defining it. According to Leakey and Lewin, man and his surrounding species are end products of history and chance. Now, however, humans have the unique opportunity to recognize their influence on the global ecosystem, and consciously steer the outcome in order to avoid triggering an unimaginable upheaval.

Download or read book Bioinformatics written by Pierre Baldi and published by MIT Press (MA). This book was released on 1998 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: An unprecedented wealth of data is being generated by genome sequencing projects and other experimental efforts to determine the structure and function of biological molecules. The demands and opportunities for interpreting these data are expanding more than ever. Biotechnology, pharmacology, and medicine will be particularly affected by the new results and the increased understanding of life at the molecular level. Bioinformatics is the development and application of computer methods for analysis, interpretation, and prediction, as well as for the design of experiments. It has emerged as a strategic frontier between biology and computer science. Machine learning approaches (e.g., neural networks, hidden Markov models, and belief networks) are ideally suited for areas where there is a lot of data but little theory—and this is exactly the situation in molecular biology. As with its predecessor, statistical model fitting, the goal in machine learning is to extract useful information from a body of data by building good probabilistic models. The particular twist behind machine learning, however, is to automate the process as much as possible. In this book, Pierre Baldi and Soren Brunak present the key machine learning approaches and apply them to the computational problems encountered in the analysis of biological data. The book is aimed at two types of researchers and students. First are the biologists and biochemists who need to understand new data-driven algorithms, such as neural networks and hidden Markov models, in the context of biological sequences and their molecular structure and function. Second are those with a primary background in physics, mathematics, statistics, or computer science who need to know more about specific applications in molecular biology.
