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.
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.
Neuroscience of the Nonconscious Mind includes novel concepts and insights on the brain mechanisms that control nonconscious mental functions, some of which were developed in the author's laboratory. The book describes neuroscience of conventional nonconscious mental functions, along with not so conventional functions like creativity, hypnosis and extrasensory perception, thus making it a very unique reference. This thought provoking book for students of mind, brain and consciousness will help explain concepts and introduce the science behind the nonconscious.
The physical world is infinitely complex, yet most of us are able to find our way around it. We can walk through unfamiliar streets while maintaining a sense of direction, take shortcuts along paths we have never used and remember for many years places we have visited only once. These are remarkable achievements. In Wayfinding, Michael Bond explores how we do it: how our brains make the ‘cognitive maps’ that keep us orientated, even in places that we don’t know. He considers how we relate to places, and asks how our understanding of the world around us affects our psychology and behaviour. The way we think about physical space has been crucial to our evolution: the ability to navigate over large distances in prehistoric times gave Homo sapiens an advantage over the rest of the human family. Children are instinctive explorers, developing a spatial understanding as they roam. And yet today few of us make use of the wayfaring skills that we inherited from our nomadic ancestors. Most of us have little idea what we may be losing. Bond seeks an answer to the question of why some of us are so much better at finding our way than others. He also tackles the controversial subject of sex differences in navigation, and finally tries to understand why being lost can be such a devastating psychological experience. For readers of writers as different as Robert Macfarlane and Oliver Sacks, Wayfinding is a book that can change our sense of ourselves.
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.
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.
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.
Thermoregulation, Part II: From Basic Neuroscience to Clinical Neurology, Volume 155, not only reviews how body temperature regulation changes in neurological diseases, but also how this aspect affects the course and outcomes of each disease. Other sections of the volume review three therapeutic approaches that are aimed at manipulating body temperature, including induced hypothermia, induced hyperthermia and antipyretic therapy. The book is comprised of nine sections across two volumes, five dealing with the basic aspects of body temperature regulation and four dealing with the clinical aspects. Basic sections cover the Thermoregulation system, Thermoreceptors, Thermoeffectors, Neural pathways, and Thermoregulation as a homeostatic function. In addition, the book covers the physiology and neuroanatomy of the thermoregulation system and provides descriptions of how the regulation of body temperature intervenes with other physiological functions (such as sleep, osmoregulation, and immunity), stress, exercise and aging. Basic sections serve as an introduction to the four clinical sections: Body Temperature, Clinical Significance, Abnormal Body Temperature, Thermoregulation in Neurological Disease and Therapeutic Interventions.
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.

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.
'Nobody bewitched by these mysteries can afford to ignore the solution proposed by Mark Solms' - Oliver Burkeman, Guardian 'A remarkable book. It changes everything' - Brian Eno How does the mind connect to the body? Why does it feel like something to be us? For one of the boldest thinkers in neuroscience, solving this puzzle has been a lifetime's quest. Now at last, the man who discovered the brain mechanism for dreaming appears to have made a breakthrough. The very idea that a solution is at hand may seem outrageous. Isn't consciousness intangible, beyond the reach of science? Yet Mark Solms shows how misguided fears and suppositions have concealed its true nature. Stick to the medical facts, pay close attention to the eerie testimony of hundreds of neurosurgery patients, and a way past our obstacles reveals itself. Join Solms on a voyage into the extraordinary realms beyond. More than just a philosophical argument, The Hidden Spring will forever alter how you understand your own experience. There is a secret buried in the brain's ancient foundations: bring it into the light and we fathom all the depths of our being.
This book on wetlands ecosystems in Asia deals with function and management. It is the first volume in the Developments in Ecosystems series.
This book presents a comprehensive and innovative understanding of the role of shallow coastal ecosystems in carbon cycling, particularly marine carbon sequestration. Incorporating a series of forward-looking chapters, the book combines thorough reviews of the global literature and regional assessments-mainly around the Indo-Pacific region and Japan-with global perspectives to provide a thorough assessment of carbon cycling in shallow coastal systems. It advocates the expansion of blue-carbon ecosystems (mangroves, seagrass meadows, and salt marshes) into macroalgal beds, tidal flats, coral reefs, and urbanized shallow waters, demonstrating the potential of these ecosystems as new carbon sinks. Moreover, it discusses not only topics that are currently the focus of blue-carbon studies, i.e., sedimentary carbon stock and accumulation rate, but also CO2 gas exchange between the atmosphere and shallow coastal ecosystems, carbon storage in the water column as refractory organic carbon, and off-site carbon storage. Including highly original contributions, this comprehensive work inspires research beyond the specific regions covered by the chapters. The suite of new concepts and approaches is refreshing and demonstrates that blue-carbon research is indeed a vibrant new field of research, providing deep insights into neglected aspects of carbon cycling in the marine environment. At the same time the book provides guidance for policy makers to deliver benefits to society, for example the inclusion of blue carbon as a carbon offset scheme or the Nationally Determined Contribution (NDC) in the Paris Agreement, and also for building resilience in coastal socio-ecosystems through better management. This book is intended for all those interested in the science and management of coastal ecosystems.
Identifying the motive force is central to explaining chromosome motions during mitosis. Presently, there is no consensus on what it is. The author has proposed a minimal assumptions model for the dynamics of post-attachment chromosome motions based on nanoscale electrostatics. Given the electrical properties of tubulin and the dynamic instability of microtubules, it is possible to account for prometaphase post-attachment, metaphase, and anaphase chromosome motions within a comprehensive model. The model addresses all of the following in a unified manner: Efficiency of aster and spindle assembly and the motive force for the motion of asters and forming half-spindles. Chromatid pair attachment. Motion of monovalently attached chromatid pairs. Motion of bivalently attached chromatid pairs and chromosome congression. Metaphase chromatid pair oscillations. Chromatid separation and anaphase-A chromosome motion. Anaphase-B pole separation. An ab-initio calculation of the maximum tension force exerted by a microtubule during mitosis that falls within the experimental range. Poleward force generation of chromosomes at poles with associated microtubule flux.

Most people find colorful brain scans highly compelling-and yet, many experts don't. This discrepancy begs the question: What can we learn from neuroimaging? Is brain information useful in fields such as psychiatry, law, or education? How do neuroscientists create brain activation maps and why do we admire them? Casting Light on The Dark Side of Brain Imaging tackles these questions through a critical and constructive lens-separating fruitful science from misleading neuro-babble. In a breezy writing style accessible to a wide readership, experts from across the brain sciences offer their uncensored thoughts to help advance brain research and debunk the craze for reductionist, headline-grabbing neuroscience. This collection of short, enlightening essays is suitable for anyone interested in brain science, from students to professionals. Together, we take a hard look at the science behind brain imaging and outline why this technique remains promising despite its seldom-discussed shortcomings.
Dynamic Thinking: A Primer on Dynamic Field Theory introduces the reader to a new approach to understanding cognitive and neural dynamics using the concepts of Dynamic Field Theory (DFT). Dynamic Neural Fields are formalizations of how neural populations represent the continuous dimensions of perceptual features, movements, and cognitive decisions. The concepts of DFT establish links between brain and behavior, revealing ways in which models of brain function can be tested with both neural and behavioral measures. Thus, DFT bridges the gap between brain and behavior, between neuroscience and the behavioral sciences. The book provides systematic tutorials on the central concepts of DFT and their grounding in both dynamical systems theory and neurophysiology. The concrete mathematical implementation of these concepts is laid out, supported by hands-on exercises that make use of interactive simulators in MATLAB. The book also contains a large set of exemplary case studies in which the concepts and associated models are used to understand how elementary forms of embodied cognition emerge and develop.
No longer confined to medical devices, medical software has become a pervasive technology giving healthcare operators access to clinical information stored in electronic health records and clinical decision support systems, supporting robot-assisted telesurgery, and providing the technology behind ambient assisted living. These systems and software must be designed, built and maintained according to strict regulations and standards to ensure that they are safe, reliable and secure. Engineering High Quality Medical Software illustrates how to exploit techniques, methodologies, development processes and existing standards to realize high-confidence medical software. After an introductory survey of the topic the book covers global regulations and standards (including EU MDD 93/42/EEC, FDA Title 21 of US CFR, ISO 13485, ISO 14971, IEC 52304, IEEE 1012 and ISO/IEC 29119), verification and validation techniques and techniques, and methodologies and engineering tasks for the development, configuration and maintenance of medical software.
Ecometabolomics: Metabolic Fluxes versus Environmental Stoichiometry focuses on the interaction between plants-particularly plants that have vigorous secondary metabolites-and the environment. The book offers a comprehensive overview of the responses of the metabolome of organisms to biotic and abiotic environmental changes. It includes an introduction to metabolomics, summaries of metabolomic techniques and applications, studies of stress in plants, and insights into challenges. This is a must-have reference for plant biologists, plant biochemists, plant ecologists and phytochemists researching the interface between plants and the environment using metabolomics.
Rock surfaces provide a challenging habitat for a broad diversity of micro- or small-sized organisms. They interact with each other forming complex communities as well with their substrate causing biodeterioration of rock. Extreme fluctuation in light, temperature and hydration are the main factors that determine the rock surface habitats. The habitat includes epilithic organisms which thrive on the surface without penetrating the rock, endolithic organisms which live just beneath the surface using a thin layer of the rock surface for protection against adverse conditions of the environment (e.g. light protection, storage of water) and chasmo-endolithic organisms which use fractures of the rock surface for a more habitable environment. The book will provide an overview of the various organismal groups, from prokaryotes to vascular plants and arthropods, as well as survey organism-mediated interactions with the rock surface. The latter include biogenic weathering (biogeochemistry, state-of-the art imaging methods), photosynthesis and nitrogen fixation at and inside the rock surface.
