This title includes a number of Open Access chapters. Earth science is a broad field of study that encompasses many different disciplines, including meteorology, climatology, and geology. The importance of the earth sciences-in predicting weather and climate, tracking pollution, drilling for petroleum, evaluating soil, and monitoring ground water-is paramount in modern society. This new work covers a broad selection of topics, including use of satellite remote sensing to track pollution and weather patterns, monitoring for pre-earthquake signals, using earthquakes to uncover new information about the earth, desalination of ground water, predicting deforestation, and much more.
Whale sharks are the largest of all fishes, fascinating for comparative studies of all manner of biological fields, including functional anatomy, growth, metabolism, movement ecology, behavior and physiology. These gentle ocean giants have captured the interest of scientists and the imagination of the public, yet their future is uncertain. The conservation status of whale sharks was upgraded to Endangered on the IUCN Red List and the species faces a range of intense threats from human activities. Can these iconic living animals, who have survived for millions of years, survive us? Written by the world's leading experts in whale shark biology, ecology, and conservation, Whale Sharks: Biology, Ecology and Conservation is the first definitive volume about the world's biggest fish. Chapters include discussions of satellite-linked tags, used to track whale shark movements; genetic sequencing, to examine evolutionary adaptations; even the use of underwater ultrasound units to investigate the species' reproduction. The editors hope that by collating what is known, they can make it easier for future researchers, conservationists, and resource managers to fill some of the remaining knowledge gaps, and provide the information they need to join the team. As you work your way through this book, we hope that you will develop a sense of awe and marvel at all of our good fortune to share the ocean, and the planet, with this utterly extraordinary species.

The contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance. Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants' roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply. The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system's properties, mostly those of mechanical nature. The presented work's chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters' contents underscore the bioinspiration as the key landmark of the proposed monograph.
More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.
Communicating Endangered Species: Extinction, News, and Public Policy is a multidisciplinary environmental communication book that takes a distinctive approach by connecting how media and culture depict and explain endangered species with how policymakers and natural resource managers can or do respond to these challenges in practical terms. Extinction isn't new. However, the pace of extinction is accelerating globally. The International Union for Conservation of Nature classifies more than 26,000 species as threatened. The causes are many, including climate change, overdevelopment, human exploitation, disease, overhunting, habitat destruction, and predators. The willingness and the ability of ordinary people, governments, scientists, nongovernmental organizations, and businesses to slow this deeply disturbing acceleration are uncertain. Meanwhile, researchers around the world are laboring to better understand and communicate the possibility and implications of extinctions and to discover effective tools and public policies to combat the threats to species survival. This book presents a history of news coverage of endangered species around the world, examining how and why journalists and other communicators wrote what they did, how attitudes have changed, and why they have changed. It draws on the latest research by chapter authors who are a mix of social scientists, communication experts, and natural scientists. Each chapter includes a mass media and/or cultural aspect. This book will be essential reading for students, natural resource managers, government officials, environmental activists, and academics interested in conservation and biodiversity, environmental communication and journalism, and public policy.
Bees are flying insects of the order Hymenoptera closely related to wasps and ants. The ancestors of bees are assumed to be predatory wasps, which switched to pollen consumption. Further, bees co-evolved with flowering plants and divided into several species according to climatic conditions. Widely known bees are western bees Apis mellifera, and eastern bees Apis cerana. This book sheds light on features of evolution, phylogenesis, speciation, adaptation to environment, and taxonomy of bees. It will be of particular relevance to evolutionists, geneticists, taxonomists, ecologists, population geneticist, and breeders.

This book offers a unique perspective on Zionism. The author, a geneticist by training, focuses on science, rather than history. He looks at the claims that Jews constitute a people with common biological roots. An argument that helps provide justification for the aspirations of this political movement dedicated to the return of the Jewish people to their homeland. His study explores two issues. The first considers the assertion that there is a biology of the Jews. The second deals with attempts to integrate this idea into a consistent history. Both issues unfolded against the background of a romantic national culture of Western Europe in the 19th century: Jews, primarily from Eastern Europe, began to believe these notions and soon they took the lead in the re-formulation of Jewish and Zionist existence. The author does not intend to present a comprehensive picture of the biological literature of the origins of a people and the blood relations between them. He also recognizes that the subject is emotionally-loaded. The book does, however, present a profound mediation on three overlapping questions: What is special or unique to the Jews? Who were the genuine Jews? And how can one identify Jews? This volume is a revised and edited English version of Tzionut Vehabiologia shel Hayehudim, published in 2006.

This inter-disciplinary book provides the latest advanced knowledge of plant effects on vegetated soil properties such as water retention capability, water permeability function, shear strength, slope hydrology, movements and failure mechanisms, and applies this knowledge to the solution of slope stability problems. It is the first book to cover in detail not only the mechanical effects of root reinforcement but more importantly the hydrological effects of plant transpiration on soil suction, soil shear strength, and water permeability. The book also offers a fundamental understanding of soil-plant-water interaction. Analytical equations are provided for predicting the combined hydrological and mechanical effects of plant roots on slope stability. A novel method is also given for simulating transpiration-induced suction in a geotechnical centrifuge. Application of this method to the study of the failure mechanisms of vegetated slopes reinforced by roots with different architectures is discussed. This book is essential reading for senior undergraduate and postgraduate students as well as researchers in civil engineering, geo-environmental engineering, plant ecology, agricultural science, hydrology and water resources. It also provides advanced knowledge for civil engineers seeking "green" engineering solutions to combat the negative impact of climate change on the long-term engineering sustainability of infrastructure slopes. Professionals other than civil engineers, such as ecologists, agriculturists, botanists, environmentalists, and hydrologists, would also find the book relevant and useful.

Chlorophyll a fluorescence is a tool for evaluating plant responses to stress conditions. Fluorescence can be used in plant phenotyping and breeding programs to monitor biotic and abiotic stresses including mineral deficiencies, soil salinity, and pathogenic diseases. Chlorophyll Fluorescence: Understanding Crop Performance - Basics and Applications reviews a diversity of instruments available for recording and analyzing different types of light signals from plants and addresses the use of chlorophyll a fluorescence in research on plants and other photosynthesizing organisms, such as algae and cyanobacteria. This book characterizes the phenomenon of chlorophyll a fluorescence, describes the methods for its measurement, and demonstrates - using selected examples - the applicability of these methods to research the response of the photosynthetic apparatus and plant tolerance to unfavorable environmental conditions. In addition, chapters cover a general background on photosynthesis, analysis of delayed fluorescence, and the pulse amplitude modulated (PAM) technique. The book is addressed to a wide range of professionals in photosynthesis research and scientists from other areas of plant sciences.
Originally published in 1987, Conservation of Ecosystems and Species examines conservation as a major world issue for governments, industrialists and the general public. The need for conservation has become more urgent as human activity continues to encroach upon the remaining natural ecosystems of our planet. This book examines a wide range of conservation issues and explains the scientific reasons why conservation of ecosystems and species is important, not merely for its own sake, but for the future of humanity. It charts the development of conservation policy around the concept and understanding of the ecosystem. The roles of the planner, the industrialist and the politician in the development of a conservation policy are described.
This book assesses the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), examining both implementation and compliance. Humans are causing a biodiversity crisis, where 1 million species are facing extinction. Species are dying, in no small part, because they are overexploited, poached and trafficked and CITES is the main international instrument designed to protect traded wildlife. Does the state of the world's species mean CITES is failing? This book explores the implementation of and compliance with CITES by all 183 member countries. It is imperative we know the nature and extent of the implementation of and compliance with CITES legislation in all parties to fully understand the impact of legal and illegal trade on species survival. Through extensive legislative content analysis, a Delphi iterative survey, and semi-structured interviews, this is the first book to share empirical research about CITES implementation and compliance. This book contains a comprehensive analysis of the state of CITES, what is done well, what could be done better, and what the future might bring to try to curtail the slide of the world's wildlife into extinction. By identifying lessons learned in relation to CITES legislation, implementation and compliance this book provides hard evidence to member countries as to how their own practice can be improved. This timely book will be essential reading for students and academics interested in wildlife law, trade and trafficking, green criminology and biodiversity conservation more broadly. It will also be of interest to professionals working in wildlife law enforcement.

A pioneering work of ecological philosophy that has been acclaimed since its first publication A highly original and engaging linking of philosophy and science and Spinoza and Einstein, resulting in a new theory of ecological ethics Even more topical and relevant now than its first publication Includes a substantial new Introduction by the author
Originally published in 1989 Social Philosophy and Ecological Scarcity presents a systematic study of the implications of ecological scarcity for social philosophy. The book argues for a new social philosophy based on a conception of the 'good society' and the 'good life' which makes fewer, rather than more demands on scarce ecological resources. The book shows that the two major competing social philosophies in modern philosophical thought - the bourgeois liberal and the state socialist - are both forms of capitalism. Despite their obvious differences, they both pursue the logic of capitalism, of ever-increasing accumulation, growth and consumption. This pursuit is carried out by means of modern science and its technology, which assume that Nature's resources are inexhaustible and can be exploited to meet infinite human wants or needs, ignoring ecological scarcity. The recognition of ecological scarcity would lead to a social philosophy, based on a frugal mode of socialism which has more affinities with the social visions of Fourier and Morris than with that of Marx. Their theories, far from being too 'utopian', are shown as more 'realistic' and less 'fantastic' than either bourgeois capitalism or state capitalism based on the Marxist model.
Originally published in 1992 Economics for the Wilds argues that an economics that properly values the resources of the wilds offers the best long-term security for their future. Most of the world's wilds have, in fact, always been utilized by local societies who have managed their resources sustainably, and one important guarantee for their preservation is therefore the continued participation of those communities and an adequate reward to them for their management. The book looks at the complexity and global nature of the issues, at the application of economics to the wilds and at the policies for their conservation and sustainable management which then result. It also examines specific forms of utilization of wild species and habitats, both sustainable and unsustainable, and including community-based development, tourism, the use of rainforest products, poaching and the impact of conservation on wildlife use. The book concludes that a comprehensive utilization strategy for wild resources is needed to ensure their continued existence and the continued flow of benefits from them.
Originally published in 1981 Historical Plant Geography is an introductory treatment of historical plant geography and stresses the basic theoretical frame of the subject. The book is about neither the study of vegetation nor the concept of the ecosystem, instead focusing on the much older tradition concerned with analysing the geographical distribution of individual species and natural plant groups. Important areas are discussed, such as global plate tectonics and sea-floor spreading, plant maps are introduced and there is a basic treatment of recent advances in plant taxonomy. The book will appeal to students and academics of geography, botany, ecology and environmental sciences. |
