Nowhere on Earth is the challenge for ecological understanding greater, and yet more urgent, than in those parts of the globe where human activity is most intense - cities. People need to understand how cities work as ecological systems so they can take control of the vital links between human actions and environmental quality, and work for an ecologically and economically sustainable future. An ecosystem approach integrates biological, physical and social factors and embraces historical and geographical dimensions, providing our best hope for coping with the complexity of cities. This book is the first of its kind to bring together leaders in the biological, physical and social dimensions of urban ecosystem research with leading education researchers, administrators and practitioners, to show how an understanding of urban ecosystems is vital for urban dwellers to grasp the fundamentals of ecological and environmental science, and to understand their own environment.
This book looks at how three kinds of strongly electric fishes
literally became "electrical," and how they helped to change the
sciences and medicine. These fishes are the flat torpedo rays
common to the Mediterranean, the electric catfishes of Africa, and
an "eel" from South America. The discovery of the electrical nature
of these fishes in the second half of the 18th century was the
starting point of the two fundamental advances in the sciences: on
the physiological side, the demonstration that nerve conduction and
muscle excitation are electrical phenomena, and on the physical
side, the invention of the electric battery. Starting with catfish
tomb drawings from Ancient Egypt and colorful descriptions of
torpedoes from the Classical Era, the authors show how these fishes
were both fascinating and mysterious to the ancients. After all,
not only could they produce torpor and temporary numbness when
touched, they could stun through intermediaries, such as wet nets
and spears.
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.
In a world where natural selection has shaped adaptations of
astonishing ingenuity, what is the scope and unique power of
rational thinking?
The study of ecosystems, fundamental to ecology, has been complemented by the growing field of landscape ecology. Ecosystem Function in Heterogeneous Landscapes addresses how interactions among ecosystems affect the functioning of individual ecosystems and the larger landscape. This groundbreaking synthesis unites ecosystem ecology's knowledge of system function with landscape ecology's knowledge of spatial structure. Practical concerns about scaling up from individual ecosystems to larger landscapes require an understanding of how networks of interacting ecosystems function together. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management. The distinguished authors discuss how how much heterogeneity needs to be taken into account for specific types of scientific and management issues. Their chapters cover the spectrum from proposing novel conceptual approaches to detailing the practical implications of heterogeneous landscapes for fire management, water management and conservation planning.
This second edition shows how long non-coding RNAs (lnc)RNAs have emerged as a new paradigm in epigenetic regulation of the genome. Thousands of lncRNAs have been identified and observed in a wide range of organisms. Unlike mRNA, lncRNA have no protein-coding capacity. So, while their function is not entirely clear, they may serve as key organizers of protein complexes that allow for higher order regulatory events. Advances in the field also include better characterization of human long non-coding RNAs, novel insights into their roles in human development and disease, their diverse mechanisms of action and novel technologies to study them.
The Evolution of Social Wasps resolves one of evolution's most intriguing problems - the origin of insect sociality. It also challenges conceptual approaches that have dominated three decades of social behaviour research. Hunt's innovative model integrates life history, nutrition, development and ecology. His broad synthesis of empirical knowledge on social wasps should interest evolution biologists, behavioural ecologists, or entomologists alike.
Theory of Endobiogeny, Volume 3: Advanced Concepts for Treatment of Complex Clinical Conditions explains complex and multi-factorial disorders and diseases using the theory of endobiogeny. It provides detailed applications of biological modeling, in-depth assessment into common disorders, an endobiogenic analysis, guidance on using biological modeling tools, and suggestions for treatment using standard of care treatments that also take into account diet, lifestyle and medicinal plants. This approach is an evolution in thinking from reductionism to holism, offering advice for symptomatic treatments that can be used in conjunction with a new way of thinking about diseases and disease management.
Comprehensive expose, by leading neuroscientists, of current knowledge on the neurotransmitter acetylcholine in the cerebral cortex. All aspects of the subject are covered, from its most elementary, at the molecular and cellular levels, to its systemic and holistic implications, including its role in cognition and involvement in human diseases and therapeutics.
This book highlights modern methods and strategies to improve cereal crops in the era of climate change, presenting the latest advances in plant molecular mapping and genome sequencing. Spectacular achievements in the fields of molecular breeding, transgenics and genomics in the last three decades have facilitated revolutionary changes in cereal- crop-improvement strategies and techniques. Since the genome sequencing of rice in 2002, the genomes of over eight cereal crops have been sequenced and more are to follow. This has made it possible to decipher the exact nucleotide sequence and chromosomal positions of agroeconomic genes. Most importantly, comparative genomics and genotyping-by-sequencing have opened up new vistas for exploring available biodiversity, particularly of wild crop relatives, for identifying useful donor genes.
Civilization, Beyond Our Fall explores the realities behind the rise and fall of historic civilizational ideals, especially on the fate of the Western vision. The book begins with the rise, durability, and fall of the historic civilizational profiles of humankind. It continues with the decline of the West, which from our perspective began with World War I and has continued at a faster pace in the 21st century. Itzkoff's prognosis for the next century or two is one of a dismal world of chaos, war, and deep pessimism throughout the world. The book concludes with a prediction of a world of scientific rationalism that will discard the ideologies, irrationalism, and selfishness that now characterize our elites. Here we leave dystopian realities for the perennial human hope of reason and for highly creative communities.
Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.
Insect Hearing provides a broadly based view of the functions, mechanisms, and evolution of hearing in insects. With a single exception, the chapters focus on problems of hearing and their solutions, rather than being focused on particular taxa. The exception, hearing in Drosophila, is justified because, due to its ever growing toolbox of genetic and optical techniques, Drosophila is rapidly becoming one of the most important model systems in neurobiology, including the neurobiology of hearing. Auditory systems, whether insectan or vertebrate, must perform a number of basic tasks: capturing mechanical stimuli and transducing these into neural activity, representing the timing and frequency of sound signals, distinguishing between behaviorally relevant signals and other sounds and localizing sound sources. Studying how these are accomplished in insects offers a valuable comparative view that helps to reveal general principles of auditory function.
This volume comprehensively reviews recent advances in our understanding of the diversity of microbes in various types of terrestrial ecosystems, such as caves, deserts and cultivated fields. It is written by leading experts, and highlights the culturable microbes identified using conventional approaches, as well as non-culturable ones unveiled with metagenomic and microbiomic approaches. It discusses the role of microbes in ecosystem sustainability and their potential biotechnological applications. The book further discusses the diversity and utility of ectomycorrhizal and entomopathogenic fungi and yeasts that dwell on grapes, it examines the biotechnological applications of specific microbes such as lichens, xylan- and cellulose-saccharifying bacteria and archaea, chitinolytic bacteria, methanogenic archaea and pathogenic yeasts.
The sheath nematodes belonging to the superfamily Hemicycliophoroidea are unique amongst all plant parasitic nematodes known to man due to the presence of an extra cuticular covering or sheath over the inner cuticle and body of all juvenile and adult life stages. These plant-parasitic nematodes include species of agricultural and quarantine importance. In Systematics of the Sheath Nematodes of the Superfamily Hemicycliophoroidea John Chitambar and Sergei Subbotin provide a detailed review of the taxonomy and diagnosis of the superfamily, its member genera and 153 related species based on their morphological and molecular analyses, as well as a further understanding of the relationships within the superfamily using molecular phylogenetics. In addition, Chitambar and Subbotin also give detailed information on the global distribution, biology, host-parasite relationships and ecology of sheath nematodes.
Human sexual nature today experiences many unanswered questions. Why does woman respond more slowly than man in arousal? What is the significance of the human orgasm? Why does sexual experience so often fail to form a lasting relationship? When is the most vulnerable time for a relationship in the process of formation? These and other questions are supported to find answers in our evolutional history. In this wide ranging and penetrating study the author finds human sexual nature to be basically inclined to committed relationships. The deepest evolutional trend, having early vertebrate origins, he finds to be the increasing biological investment in the unit young of each new generation.
Egyptian coastal lakes and wetlands are among the most productive wetland ecosystems in the world. This volume explores their current status and how it can be maintained and improved. It describes the five Northern coastal lakes, their origin, physical and chemical properties and current development activities, and discusses the challenges facing these lakes, such as shrinking, pollution, degradation, and adaptive management. Further topics include hydrodynamics and modeling techniques, as well as strategies for the sustainable development of these valuable resources. The book closes with a concise summary of the conclusions and recommendations presented in the chapters. As such, it offers an invaluable resource for the academic community and postgraduate students, as well as for environmental managers and policymakers.
This book focuses on advances in our understanding of the regulatory mechanisms of brain iron uptake, iron homeostasis and iron metabolism in the pathophysiology and pharmacology of CNS disease models. Dysregulation of brain iron homeostasis can lead to severe pathological changes in the neural system. Iron deficiency can slow down the development of the neural system and cause language and motion disorders, while iron overload is closely related to neurodegenerative diseases. Although some current books include chapters on iron metabolism and certain neurodegenerative diseases, this is the first systematic summary of the latest discoveries regarding brain iron metabolism and CNS diseases. By providing novel and thought-provoking insights into the mechanisms and physiological significance of brain iron metabolism and related diseases, the book stimulates further new research directions. It helps graduate students and researchers gain an overall picture of brain iron metabolism and the pathogenesis of neurodegenerative diseases, and also offers pharmaceutical companies inspiration for new treatment strategies for CNS diseases.
