This book was released on 2014-04-29 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleontologists and geologists struggle with research questions often complicated by the loss or even absence of key paleobiological and paleoenvironmental information. Insight into this missing data can be gained through direct exploration of analogous living organisms and modern environments. Creative, experimental and interdisciplinary treatments of such ancient-Earth analogs form the basis of Lessons from the Living. This volume unites a diverse range of expert paleontologists, neontologists and geologists presenting case studies that cover a spectrum of topics, including functional morphology, taphonomy, environments and organism-substrate interactions.

Download or read book Water Balance in Land Arthropods written by E. B. Edney and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writers on arthropod water relationships range from bio physicists and biochemists to population ecologists-a fact that gives cause to wonder whether the field is already too heterogeneous to be written about in a single book by a single author. I have partly avoided the problem by concentrating largely on physiological mechanisms and by omitting most aspects of behavioural regulation and most aspects of heat balance and body temperature, except when these impinge directly on water balance. Even within this limited field there has been a lot of work during the past twenty years, as a result of which some problems have been solved (or at least more clearly defined), and many others have been opened up. On the whole there has been a welcome change to a more rigorous experimental approach and it is now possible for water balance people to state their problems in physiological terms. Good progress has been made towards understanding the mechanisms involved in nearly all avenues of water uptake and loss, although problems indeed remain. The cuticle has yielded part of its secrets to electron micrography, but ex ploration by means oflipid biochemistry among other techniques is necessary for a real understanding of cuticle permeability.

Download or read book Toxins and Hemostasis written by R. Manjunatha Kini and published by Springer Science & Business Media. This book was released on 2010-10-19 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Circulation of blood is vital for the survival of vertebrates, including man. Mainly, it plays an important role in carrying food nutrients and oxygen to every tissue and organ and in removing all waste products and carbon dioxide. Any imbalance in the hemostatic and cardiovascular systems can lead to death and severe debility. A number of animals have developed mechanisms to target these systems and exploit the vulnerability. In some species (for example, snakes), such mechanisms are used to immobilize and kill the victim/prey, whereas in others (for example, insects, such as leaches, mosquitoes and ticks), they are used to provide a continuous supply of blood. These mechanisms include, but are not limited to, procoagulant and anticoagulant actions that affect the coagulation cascade and platelet aggregation, as well as altering vasodilatory responses. In all these various animals, these mechanisms have evolved to perfection over millions of years to support their survival. In last 3-4 decades, due to the efforts of scientists from various backgrounds including biology, protein chemistry, molecular biology, pharmacology, hematology, and structural biology, significant progress in understanding the structure-function relationships, as well as the mechanism of action have been made in a number of exogenous factors that affect blood coagulation, platelet aggregation and vasodilation from various animals. These exogenous factors have contributed significantly to the development of research tools as well as providing new therapeutic agents. With the increase average age of the population coupled with changes in life style in recent years, there has been a significant increase in cardiovascular and hematological disorders. Thus scientists in both academic institutions as well as the pharmaceutical industry are developing better therapeutic agents to improve the quality of life. This impetus has lead to the search for novel agents from various sources that interfere with cardiovascular and hematalogical processes. Although at first glance exogenous factors appear to function as ‘villains’, several life-saving drugs have been developed based upon these factors. Such drugs or drug leads include those that inhibit the angiotensin converting enzymes (Captopril and Enalapril), that block platelet receptors (Eptifibatide and Tirofiban), or that digest thrombotic plugs (Alfimeprase and bat plasminogen activator) to name a few. Several new and exciting success stories are currently unfolding. In this book, recent studies on some of the exogenous factors that play crucial roles in cardiovascular and hematological disorders are reviewed in order to consolidate the efforts in this area of research and to recruit new, talented researchers. The 25-30 review chapters, each written by experts in their field, compiled herein are devoted to exogenous factors affecting platelet aggregation, anticoagulant and procoagulant proteins, fibrinolytic proteins and hypotensive agents (For details see, Contents of the Book). This book is intended to help to create elevated awareness and enthusiasm in the field of exogenous factors. I believe that this book will provide greater impetus to the search for novel proteins based on naturally occurring exogenous factors. This will be the first book dealing extensively with exogenous factors in the last 25 years. The book will provide a ready reference to the different approaches used to solve complex problems in protein chemistry and pharmacology of exogenous factors. The book will update our understanding of the structure-function relationships and mechanisms of action of exogenous factors and provide great insights into future directions for solving the remaining challenges.

This book was released on 2015-06-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This situation analysis was undertaken to inform responses to several resolutions made at the 5th World Conservation Congress in 2012 about the plight of large vertebrates in West and Central Africa. It draws on a wide range of information to provide information on the status of these species, important sites, pressures, legislation, the effectiveness of protected areas, and both community-based incentives for conservation and institutional responses. The overriding conclusion is of substantial wildlife declines and inadequate responses to either long-standing pressures or rapidly escalating threats that have emerged in recent years.

Download or read book Catalog of the Scorpions of the World 1758 1998 written by Victor Fet and published by . This book was released on 1997 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique and timely publication is the first such Catalog to be produced in over 100 years. The last full survey of the taxonomy of the world fauna of the Order Scorpiones was by Karl Kraepelin in 1899 - Scorpiones und Pedipalpi. Das Tierreich. Herausgegeben von der Deutschen Zoologischen Gesellschaft. Berlin. Since then, the sheer number of known species and subspecies has increased more than fourfold, and the classification of scorpions has been greatly transformed at both the generic and familial levels. This new Catalog brings together under one cover an enormous amount of difficult-to-locate information on scorpion nomenclature, biogeography, distribution and phylogeny, published before and after Kraepelin's time. It is of special interest because of the unique status that scorpions currently enjoy as models for the study of evolutionary biology, ecology, toxicology, and physiology. The Catalog is much more than a checklist - it is an annotated, organized compendium of the status of the entire field of Scorpion Taxonomy at the beginning of the New Millennium, by authoritative and critical researchers working in the field. The authors have coordinated and collaborated extensively to make this a fully integrated work. The utility of the Catalog is enormously enhanced by the inclusion of much greater detail than other animal catalogs, including type data, tracing of full synonymies of all names, clarification or critical discussion of known nomenclatural problems, comprehensive cross index, and notes on biogeography and phylogeny.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive analysis of garbage trafficking, wildlife trafficking, illegal fishing, and illegal logging highlights the difficulty in balancing human interests and environmental responsibility. The alarming consequences of eco-crime go far beyond the widespread degradation of the natural world; important societal institutions are undermined and negative social and economic impacts also result from garbage trafficking, wildlife trafficking, illegal fishing, and illegal logging. In order to successfully combat these problems, a consistent, international response will be necessary. Crimes Against Nature: Illegal Industries and the Global Environment addresses an important topic that is largely unknown and rarely documented other than in reports published by environmental NGOs and a limited number of academic articles and journalistic accounts. A comprehensive and up-to-date description of each illicit industry is provided, emphasizing the damages caused, the transnational nature of these activities, the roles played by organized crime and public and private elites, and the range of possible solutions. The author addresses the complexity of balancing human concerns with environmental interests and concludes with information regarding promising recent developments.
