Darwin did not discover evolution. He didn't trip over it on the way to somewhere else the way Columbus discovered the New World. Like the atom, planetary orbits, and so many other scientific constructs, evolution was invented in order to explain striking phenomena. And it has been most successful. A century and a half has not simply confirmed Darwin's work, it has linked evolution to the mechanisms of life on the molecular scale. It is what life does. Where Darwin had drawn his theories from forest and field, we now set them in the coiling and uncoiling of twists of DNA, linking where they might, with a host of molecular bits and pieces scurrying about. Darwin, himself, however, has been a closed story. A century and a half of study of the man and his work, including close readings of his books, his notebooks and letters, and even the books he read, has led to a working appreciation of his genius. The 'success' of this account has, however, kept us from seeing several important issues: most notably, why did he pursue evolution in the first place? Buckets from an English Sea offers a new view of what inspired Darwin and provoked his work. Stunning events early in the voyage of the Beagle challenged his deeply held conviction that people are innately good. This study of 1832 highlights the resources available to the young Darwin as he worked to secure humanity's innate goodness.
This open access book sets out the contours of feminist political ecology (FPE) as a major contribution to ongoing debates in the field. In an innovative methodological twist, the edited book engages the reader in conversations that have emerged from the multi-sited and cross-generational dialogues of the Well-Being Ecology Gender cOmmunities (WEGO) network over the last four years. The conversations explore topics that range from climate change and extractivism, to body politics and health, degrowth, care and community well-being. The authors reflect on their collective learning process as they map out the new directions of FPE research and analysis. The chapters highlight WEGO transnational/transdisciplinary conversations with local communities, social movements and different academic spaces. The book foregrounds the ethics of doing feminist work inside and outside academe and brings to life the importance of doing reflexive research aware of situated historical and contemporary geographical contours of power.
This book reviews the growing literature that is consistent with the hypothesis that hormones can regulate auditory physiology and perception across a broad range of animal taxa, including humans. Understanding how hormones modulate auditory function has far reaching implications for advancing our knowledge in the basic biomedical sciences and in understanding the evolution of acoustic communication systems. A fundamental goal of neuroscience is to understand how hormones modulate neural circuits and behavior. For example, steroids such as estrogens and androgens are well-known regulators of vocal motor behaviors used during social acoustic communication. Recent studies have shown that these same hormones can also greatly influence the reception of social acoustic signals, leading to the more efficient exchange of acoustic information.
Fundamental biochemical studies of basic brain metabolism focusing on the neuroactive amino acids glutamate and GABA combined with the seminal observation that one of the key enzymes, glutamine synthetase is localized in astroglial cells but not in neurons resulted in the formulation of the term "The Glutamate-Glutamine Cycle." In this cycle glutamate released from neurons is taken up by surrounding astrocytes, amidated by the action of glutamine synthetase to glutamine which can be transferred back to the neurons. The conversion of glutamate to glutamine is like a stealth technology, hiding the glutamate molecule which would be highly toxic to neurons due to its excitotoxic action. This series of reactions require the concerted and precise interaction of a number of enzymes and plasma membrane transporters, and this volume provides in-depth descriptions of these processes. Obviously such a series of complicated reactions may well be prone to malfunction and therefore neurological diseases are likely to be associated with such malfunction of the enzymes and transporters involved in the cycle. These aspects are also discussed in several chapters of the book. A number of leading experts in neuroscience including intermediary metabolism, enzymology and transporter physiology have contributed to this book which provides comprehensive discussions of these different aspects of the functional importance of the glutamate-glutamine cycle coupling homeostasis of glutamatergic, excitatory neurotransmission to basic aspects of brain energy metabolism. This book will be of particular importance for students as well as professionals interested in these fundamental processes involved in brain function and dysfunction.
The philosophically most challenging science today, arguably, is no longer physics but biology. It is hardly an exaggeration to state that Charles Darwin has shaped modern evolutionary biology more significantly than anyone else. Moreover, since Darwin's day, philosophers and scientists have realized the enormous philosophical potential of Darwinism and have tried to expand his insights well beyond the limits of biology. However, no consensus has been achieved. The aim of this collection of essays is to revive a comprehensive discussion of the meaning and the philosophical implications of "Darwinism." The contributors to Darwinism and Philosophy are international scholars from the fields of philosophy, science, and history of ideas. A strength of this collection is that it brings together sustained reflection from American and Continental philosophical traditions. The conclusions of the contributors vary, but taken together their essays successfully map the problems of interpreting "Darwinism."
This book focuses on fluxes of energy, carbon dioxide and matter in and above a Central European spruce forest. The transition from a forest affected by acid rain into a heterogeneous forest occurred as a result of wind throw, bark beetles and climate change. Scientific results obtained over the last 20 years at the FLUXNET site DE-Bay (Waldstein-Weidenbrunnen) are shown together with methods developed at the site, including the application of footprint models for data-quality analysis, the coupling between the trunk space and the atmosphere, the importance of the Damkoehler number for trace gas studies, and the turbulent conditions at a forest edge. In addition to the many experimental studies, the book also applies model studies such as higher-order closure models, Large-Eddy Simulations, and runoff models for the catchment and compares them with the experimental data. Moreover, by highlighting processes in the atmosphere it offers insights into the functioning of the ecosystem as a whole. It is of interest to ecologists, micrometeorologists and ecosystem modelers.
The study of the molecular events leading to cellular transformation and cancer has progressed significantly in the last decade, and it has become apparent that many genes subject to modification in cancer are, in fact, transcription factors that govern the execution of the genetic programme of the cell. Transcription factors can behave either as oncogenes or as tumour suppressor genes. To date only a limited number of transcription factors have been associated with cancer. This volume deals with several transcription factor families that were first identified in oncogenic retroviruses. Each chapter contains a description of the structure of the transcription factors, the nature of target genes, the regulation of their activities, and an explaination of how they can deregulate cell growth and differentiation. This text should be suitable for the specialist scientist and the advanced student

In Neuromethods series style, chapters include the kind of detail and key advice from the specialists needed to get successful results in your laboratory. Cutting-edge and authoritative, Genomic Mosaicism in Neurons and Other Cell Types is a valuable resource for learning about the latest techniques for the analysis of genome and genetic mosaicism in vertebrate neurons.
Evolutionary developmental biology or evo-devo is a field of biological research that compares the underlying mechanisms of developmental processes in different organisms to infer the ancestral condition of these processes and elucidate how they have evolved. It addresses questions about the developmental bases of evolutionary changes and evolution of developmental processes. The book's content is divided into three parts, the first of which discusses the theoretical background of evo-devo. The second part highlights new and emerging model organisms in the evo-devo field, while the third and last part explores the evo-devo approach in a broad comparative context. To the best of our knowledge, no other book combines these three evo-devo aspects: theoretical considerations, a comprehensive list of emerging model species, and comparative analyses of developmental processes. Given its scope, the book will offer readers a new perspective on the natural diversity of processes at work in cells and during the development of various animal groups, and expand the horizons of seasoned and young researchers alike.
This book discusses the latest developments in plant-mediated fabrication of metal and metal-oxide nanoparticles, and their characterization by using a variety of modern techniques. It explores in detail the application of nanoparticles in drug delivery, cancer treatment, catalysis, and as antimicrobial agent, antioxidant and the promoter of plant production and protection. Application of these nanoparticles in plant systems has started only recently and information is still scanty about their possible effects on plant growth and development. Accumulation and translocation of nanoparticles in plants, and the consequent growth response and stress modulation are not well understood. Plants exposed to these particles exhibit both positive and negative effects, depending on the concentration, size, and shape of the nanoparticles. The impact on plant growth and yield is often positive at lower concentrations and negative at higher ones. Exposure to some nanoparticles may improve the free-radical scavenging potential and antioxidant enzymatic activities in plants and alter the micro-RNAs expression that regulate the different morphological, physiological and metabolic processes in plant system, leading to improved plant growth and yields. The nanoparticles also carry out genetic reforms by efficient transfer of DNA or complete plastid genome into the respective plant genome due to their miniscule size and improved site-specific penetration. Moreover, controlled application of nanomaterials in the form of nanofertilizer offers a more synchronized nutrient fluidity with the uptake by the plant exposed, ensuring an increased nutrient availability. This book addresses these issues and many more. It covers fabrication of different/specific nanomaterials and their wide-range application in agriculture sector, encompassing the controlled release of nutrients, nutrient-use efficiency, genetic exchange, production of secondary metabolites, defense mechanisms, and the growth and productivity of plants exposed to different manufactured nanomaterials. The role of nanofertilizers and nano-biosensors for improving plant production and protection and the possible toxicities caused by certain nanomaterials, the aspects that are little explored by now, have also been generously elucidated.
Networks of Invasion bridges a conceptual gap between ecological network studies and invasion biology studies. This book contains chapters detailing pressing concerns regarding invasive species in food webs, but also extends the idea of networks of invasion to other systems, such as mutualistic networks or even the human microbiome. Chapters describe the tools, models, and empirical methods adapted for tackling invasions in ecological networks.
This indispensable volume highlights recent studies identifying epigenetic mechanisms as essential regulators of skin development, stem cell activity and regeneration. Chapters are contributed by leading experts and promote the skin as an accessible model system for studying mechanisms that control organ development and regeneration. The timely discussions contained throughout are of broad relevance to other areas of biology and medicine and can help inform the development of novel therapeutics for skin disorders as well as new approaches to skin regeneration that target the epigenome. Part of the highly successful Stem Cells and Regenerative Medicine series, Epigenetic Regulation of Skin Development and Regeneration uncovers the fundamental significance of epigenetic mechanisms in skin development and regeneration, and emphasizes the development of new therapies for a number of skin disorders, such as pathological conditions of epidermal differentiation, pigmentation and carcinogenesis. At least six categories of researchers will find this book essential, including stem cell, developmental, hair follicle or molecular biologists, and gerontologists or clinical dermatologists.
This book consolidates the information, results, experience and perspectives of different research groups working on Chilean Saltmarshes.

This book presents a comprehensive discussion on the heterogeneity existing between different types of stem cells within the same tissue, for several types of cancers, e.g. glioblastoma stem cells. Recent developments have revealed completely different roles of distinct stem cells within the same organ. Thus, Stem Cells Heterogeneity in Cancer provides a timely update us on the current information on stem cells heterogeneity in various tissues. It also provides a solid foundation of the history of stem cells from specific tissues and the current applications of this knowledge in regenerative medicine. When taken as a whole, alongside its companion volumes Stem Cells Heterogeneity - Novel Concepts, and Stem Cells Heterogeneity in Different Organs, these three books present a comprehensive reference on stem cell heterogeneity in various tissues and current and future applications for regenerative medicine. It is essential reading for advanced cell biology students as well as researchers in stem cells and clinicians.
This book provides insights into the current state of sorghum genomics. It particularly focuses on the tools and strategies employed in genome sequencing and analysis, public and private genomic resources and how all this information is leading to direct outcomes for plant breeders. The advent of affordable whole genome sequencing in combination with existing cereal functional genomics data has enabled the leveraging of the significant novel diversity available in sorghum, the genome of which was fully sequenced in 2009, providing an unmatched resource for the genetic improvement of sorghum and other grass species. Cultivated grain sorghum is a food and feed cereal crop adapted to hot and dry climates, and is a staple for 500 million of the world's poorest people. Globally, sorghum is also an important source of animal feed and forage, an emerging biofuel crop and model for C4 grasses, particularly genetically complex sugarcane.

The Migraine Brain, edited by David Borsook, Arne May, Peter J.
Goadsby, and Richard Hargreaves, makes a major contribution to the
field, addressing the increasingly sophisticated neuroimaging
techniques that have allowed researchers to begin to define
functional and anatomical characteristics of migraine and other
less-common types of headache. Of particular focus is how imaging
is changing the way we understand migraine. This includes changes
in function, structure and chemistry of the migraine brain.
Included are sections that focus on particular aspects of migraine,
for example the migraine aura: those symptoms that cause visual
sensitivity (blinding white light), sensory difficulty (loud
noises, painful touch, and hot/cold spells), slurred language, and
motor dysfunction.
Arterial chemoreceptors are unique structures which continuously monitor changes in arterial blood oxygen, carbon dioxide, glucose, and acid. Alterations in these gases are almost instantaneously sensed by arterial chemoreceptors and relayed into a physiological response which restores blood homeostasis. Arterial Chemoreception contains updated material regarding the physiology of the primary arterial chemoreceptor; the carotid body. Moreover, this book also explores tantalizing evidence regarding the contribution of the aortic bodies, chromaffin cells, lung neuroepithelial bodies, and brainstem areas involved in monitoring changes in blood gases. Furthermore this collection includes data showing the critical importance of these chemoreceptors in the pathophysiology of human disease and possible therapeutic treatments. This book is a required text for any researcher in the field of arterial chemoreception for years to come. It is also a critical text for physicians searching for bench-to-bedside treatments for heart failure, sleep apnea, and pulmonary hypertension.
Drawing on shared research experiences and collaborative projects, this book offers a broad and timely perspective on research on the hand and its current challenges. It especially emphasizes the interdisciplinary context in which researchers need to be trained in contemporary science. From language to psychology, from neurology to the social sciences, and from art to philosophy and religion, the chapters discuss various aspects involved in hand research and therapy. On the basis of concrete and validated case studies, they approach hand function and gestures from different perspectives - not only neurological and medical, but also philosophical, evolutionary and anthropological. By highlighting the overlaps between different areas of research, the book seeks to foster better communication between researchers, and ultimately a better understanding of hand function and its recovery. It offers essential information and inspirations for students, researchers and practitioners in the fields of psychology, epistemology, bioengineering, neuroscience, anthropology and bioethics.

This highly acclaimed book brings the cumulative results of a century and a half of kinship studies in anthropology into the focus of current debates on the origin of modern humans in Africa and on an entangled bit of human evolutionary history commonly subsumed under the heading of the "peopling of the Americas." This erudite study is based on a database of some 2,500 kinship vocabularies representing roughly 600 African languages, 140 Australian languages, 500 Austronesian languages, 200 Papuan languages, 350 languages of Eurasia (excluding Indo-Europeans), 440 North and Middle American Indian languages, and 200 South American languages. This valuable reference will take the reader to the dawn of kinship studies in the 19th century Western science in order to elicit the wider context of anthropological interest in kinship systems and the interdisciplinary salience of the phenomenon of kinship. The book also examines the founder of kinship studies in anthropology, American lawyer and Iroquois ethnographer, Lewis Henry Morgan, and the circumstances of his life that generated his interest in human kinship. The study ventures into the intricacies of scientific and quasi-scientific debates in the 19th century, and treats 19th century science as embedded in a myth featuring divinity, humanity and animality as principal characters. This account is divided into four sections, each of which is structured as a triad (philosophy, psychology and physiology; logic, semiotics and reproduction; religion, hermeneutics and evolution; law, grammar and speech). This far-reaching historical journey aims at formulating an idea of what human kinship might be all about, especially in the light of the widespread uncertainties about this question caused by the constructivist turn in anthropology. Eventually our ideas regarding human origins, ancient population dispersals and the homeland of modern humans are inextricably linked to our ideas about kinship. As a book that brings together evolutionary and sociocultural anthropology, The Genius of Kinship will be a critical addition for all Anthropology collections. |
