This book was released on 2016-09-14 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is usually referred to as the ‘Molecule of Life’. It constitutes the most abundant molecule in living (micro)organisms and is also essential for critical biochemical reactions, both for the global functioning and maintenance of Ecosystems (e.g., Photosynthesis) and individual (microbial) cells (e.g., ATP hydrolysis). However, most of Earth’s terrestrial environments present deficiencies in bioavailable water. Arid environments cover around a third of the land’s surface, are found on the six continents and, with the anthropogenic desertification phenomenon, will increase. Commonly defined by having a ratio of precipitation to potential evapotranspiration (P/PET) below 1, arid environments, being either hot or cold, are characterized by scant and erratic plant growth and low densities in macro-fauna. Consequently, these ecosystems are microbially mediated with microbial communities particularly driving the essential Na and C biogeochemical cycles. Due to the relatively simple trophic structure of these biomes, arid terrestrial environments have subsequently been used as ideal ecosystems to capture and model interactions in edaphic microbial communities. To date, we have been able to demonstrate that edaphic microorganisms (i.e., Fungi, Bacteria, Archaea, and Viruses) in arid environments are abundant, highly diverse, different from those of other terrestrial systems (both in terms of diversity and function), and are important for the stability and productivity of these ecosystems. Moreover, arid terrestrial systems are generally considered Mars-like environments. Thus, they have been the favored destination for astro(micro)biologists aiming to better understand life’s potential distribution and adaptation strategies in the Universe and develop terraforming approaches. Altogether, these points demonstrate the importance of significantly improving our knowledge in the microbial community composition (particularly for Fungi, Archaea and Viruses), assembly processes and functional potentials of arid terrestrial systems, as well as their adaptation mechanisms to aridity (and generally to various other environmental stresses). This Research Topic was proposed to provide further insights on the microbial ecology of hot and cold arid edaphic systems. We provide a detailed review and nine research articles, spanning hot and cold deserts, edaphic, rhizospheric, BSC and endolithic environments as well as culture-dependent and -independant approaches.

Download or read book Historical Dictionary of Namibia written by Victor L. Tonchi and published by Scarecrow Press. This book was released on 2012-08-31 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: On March 21, 1990, Sam Nujoma was sworn in as the first president of independent Namibia. This ceremony marked the end of a struggle that lasted more than two decades and a period of colonialism that lasted more than a century. Finally, after decades long wars over grazing in the 19th century, genocidal colonial suppression by Germany at the beginning of the 20th century, repressive apartheid racialism throughout the 20th century, and a prolonged armed liberation struggle, Namibians had the chance to choose their own leaders, develop a democratic political process in a free society, and to bring economic development and greater equity to their country. The Historical Dictionary of Namibia covers the history of Namibia through a chronology, an introductory essay, appendixes, and an extensive bibliography. The dictionary section has several hundred cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent access point for students, researchers, and anyone wanting to know more about Namibia.

Download or read book Global Vegetation written by Jörg S. Pfadenhauer and published by Springer Nature. This book was released on 2020-09-09 with total page 858 pages. Available in PDF, EPUB and Kindle. Book excerpt: This up-to-date textbook of global vegetation ecology, which comprises the current state of knowledge, is long overdue and much-needed. It is a translation of the textbook “Vegetation der Erde” (Springer-Spektrum, Heidelberg). A short introductory chapter deals with the fundamentals of vegetation ecology that are of importance for the delimitation and characterization of the global vegetation presented in this book (chorology, evolution of plants, physiognomic and structural characteristics, phytodiversity and the human impact on it as well as general terminology concerning both plant growth forms and on vegetation structure types). In the following chapters the zonal and azonal vegetation from the tropics to the polar regions including high mountains is described and discussed. The main focus is on the characterization of interactions between the spatial location of plants and plant communities on the one hand and site conditions, historic and genetic processes, spatial and temporal patterns, ecophysiology and anthropogenic influences on the other hand. Additional information on specific topics is provided in 51 boxes.

Download or read book Biology of Spiders written by Rainer Foelix and published by OUP USA. This book was released on 2011-05-05 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the only books to treat the whole spider, from its behavior and physiology to its neurobiology and reproductive characteristics, Biology of Spiders is considered a classic in spider literature. First published in German in 1979, the book is now in its third edition, and has established itself as the supreme authority on these fascinating creatures. Containing five hundred new references, this book incorporates the latest research while dispelling many oft-heard myths and misconceptions that surround spiders. Of special interest are chapters on the structure and function of spider webs and silk, as well as those on spider venom. A new subchapter on tarantulas will appeal especially to tarantula keepers and breeders. The highly accessible text is supplemented by exceptional, high-quality photographs, many of them originals, and detailed diagrams. It will be of interest to arachnologists, entomologists, and zoologists, as well as to academics, students of biology, and the general reader curious about spiders.

Available in PDF, EPUB and Kindle. Book excerpt: On the eve of the World Summit for Sustainable Development (WSSD), held in autumn 2002 in Johannesburg, South Africa, United Nations Secretary General Kofi Annan recommended five specific areas as focal points of discussion for the global forum: Water, energy, health, agriculture and biodiversity. In his address, "Towards a Sustainable Future," delivered just four months before the WSSD, Secretary General Annan contended that concrete progress in each of these areas, often referred to by their acronym WEHAB, would be key to improving the quality of life not only in the developing world but across the globe. For most people, I think it is fair to say that the inclusion of biodiversity in a list that focuses on basic human needs may not be self-evident. Water, energy, health and agriculture, yes. But why biodiversity? The truth is that biodiversity is just as critical to global well-being as water, energy, agriculture and health. This is because biodiversity both drives and shapes nature's intricate and dynamic structure in an enduring form and force that enables both current and future generations to enjoy its bounty.

This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecophysiology of Desert Arthropods and Reptiles starts with a new classification of the world's deserts, based upon the type of precipitation and the effect on their faunas of arthropods and reptiles. This is followed by an account of microclimates and the avoidance of environmental extremes. Whereas thermoregulation is primarily behavioural, responses to water shortage are largely physiological. Seasonal activity and phenology are described, adaptations for burrowing, the avoidance of enemies, and defence, are also outlined. A comparative account of interspecific relationships, feeding specializations, and species diversity in the two taxa is described. The purpose of the book is to provide a new and up-to-date analysis that will stimulate further research along these lines.

This book was released on 2022-12-22 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gypsum is a type of habitat widely spread throughout the world, especially in arid climates (Somalia, Australia, Middle East, USA, circum-Mediterranean region, etc.). The vegetation present on this type of habitat has long attracted the attention of specialists in the study of flora adapted to special substrates, since gypsum represents an important barrier to the growth of most plants. These ecosystems are little known in comparison to other habitats present on special substrates, even though representing natural laboratories of evolution and ecology. In this context, the Gypworld project has been developed, as a global initiative to understand the ecology of gypsum ecosystems, comes under the European Horizon 2020 research program, and which brings together researchers specialists in the study of gypsum ecosystems, from five continents. Under the umbrella of this project, different scientific meetings have been taking place, being the one held in Almeria, the third of the four that will take place, with the name of 3rd Gypworld Workshop. Thus, this monograph presents the most recent advances in the research of these special ecosystems.

Download or read book History of Namibia written by Marion Wallace and published by Oxford University Press. This book was released on 2014-01-16 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1990 Namibia gained its independence after a decades-long struggle against South African rule--and, before that, against German colonialism. This book, the first new scholarly general history of Namibia in two decades, provides a fresh synthesis of these events, and of the much longer pre-colonial period. A History of Namibia opens with a chapter by John Kinahan covering the evidence of human activity in Namibia from the earliest times to the nineteenth century, and for the first time making a synthesis of current archaeological research widely available to non-specialists. In subsequent chapters, Marion Wallace weaves together the most up-to-date academic research (in English and German) on Namibian history, from the mid-eighteenth century to the present. She explores histories of migration, production and power in the pre-colonial period, the changes triggered by European expansion, and the dynamics of the period of formal colonialism. The coverage of German rule includes a full chapter on the genocide of 1904-8. Here, Wallace outlines the history and historiography of the wars fought in central and southern Namibia, and the subsequent mass imprisonment of defeated Africans in concentration camps. The final two chapters analyse the period of African nationalism, apartheid and war between 1946 and 1990. The book's conclusion looks briefly at the development of Namibia in the two decades since independence. A History of Namibia provides an invaluable introduction and reference source to the past of a country that is often neglected, despite its significance in the history of the region and, indeed, for that of European colonialism and international relations. It makes accessible the latest research on the country, illuminates current controversies, puts forward new insights, and suggests future directions for research. The book's extensive bibliography adds to its usefulness for scholar and general reader alike.

Download or read book Avian Energetics and Nutritional Ecology written by C. Carey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A symposium held in 1973 chaired and organized by William R. Dawson was the first major attempt to summarize and synthesize the existing information in the then emerging field of avian energetics. The symposium featured papers by James R. King, William A. Calder III, Vance A. Tucker, and Robert E. Ricklefs and com mentaries by George A. Bartholomew, S. Charles Kendeigh, and Eugene P. Odum. The proceedings of the symposium, Avian Energetics (Paynter 1974), played a critical role in stimulating interest and research in the field of avian energetics. Some twenty-odd years later, we are making another attempt to summarize the information in the field of avian energetics. Some obvious differences exist be tween its predecessor and this volume. Numerous improvements in methodology, such as the use of doubly labeled water to estimate metabolism in free-living birds, now allow researchers to ask questions that could not be addressed previ ously. Second, consideration of nutrition is now inseparable from that of energet ics. This merger is necessary not only because food intake is the source of both en ergy and nutrients but also because one or more nutrients, rather than energy, can be limiting for a given species in a particular instance. Finally, the study of ener getics and nutritional ecology, particularly in birds and mammals, has grown so dramatically that a single volume can now only partially cover the range of possi ble topics and can catalogue only a sampling of all the studies on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.
