The Central Andean Altiplane represents a unique extreme environment due to its high altitude, closed basins that modulate the salt pans and saline wetlands surrounded by deserts, as well as the considerable influence of volcanic activity. UV radiation, arsenic content, high salinity, alkalinity and low dissolved oxygen levels, together with extreme daily temperature fluctuations and oligotrophic conditions, shape an environment that resembles the early Earth and, even more, extraterrestrial conditions. By developing simple biofilms stratified microbial mats or complex microbialites, extreme microbial ecosystems, colonize and thrived in different environments like salt flats, wetlands, lakes volcano vents, geysers and deserts. This book presents our current understanding of these amazing ecosystems, providing a basis for their protection and sustainable utilization. The main audience for this book included researchers and graduate students as well as professionals working in the government, mining industry and similar activities.
The scalp and cortex lie like pages of an open book on which the cortex enciphers vast quantities of information and knowledge. They are recorded and analyzed as temporal and spatial patterns in the electroencephalogram and electrocorticogram. This book describes basic tools and concepts needed to measure and decipher the patterns extracted from the EEG and ECoG. This book emphasizes the need for single trial analysis using new methods and paradigms, as well as large, high-density spatial arrays of electrodes for pattern sampling. The deciphered patterns reveal neural mechanisms by which brains process sensory information into precepts and concepts. It describes the brain as a thermodynamic system that uses chemical energy to construct knowledge. The results are intended for use in the search for the neural correlates of intention, attention, perception and learning; in the design of human brain-computer interfaces enabling mental control of machines; and in exploring and explaining the physicochemical foundation of biological intelligence.

This book explores the impact of nonlinearity on a broad range of areas, including time-honored fields such as biology, geometry, and topology, but also modern ones such as quantum mechanics, networks, metamaterials and artificial intelligence. The concept of nonlinearity is a universal feature in mathematics, physics, chemistry and biology, and is used to characterize systems whose behavior does not amount to a superposition of simple building blocks, but rather features complex and often chaotic patterns and phenomena. Each chapter of the book features a synopsis that not only recaps the recent progress in each field but also charts the challenges that lie ahead. This interdisciplinary book presents contributions from a diverse group of experts from various fields to provide an overview of each field's past, present and future. It will appeal to both beginners and seasoned researchers in nonlinear science, numerous areas of physics (optics, quantum physics, biophysics), and applied mathematics (ODEs, PDEs, dynamical systems, machine learning) as well as engineering.
This book highlights the impact of climate change on the soil microbiome and its subsequent effects on plant health, soil-plant dynamics, and the ecosphere. It also discusses emerging ideas to counteract these effects, e.g., through agricultural applications of functional microbes, to ensure a sustainable ecosystem. Climate change is altering the soil microbiome distributions and thus the interactions in microbiome and plant-soil microorganism. Improvement of our understanding of microbe-microbe and plant-microbe interaction under changing climatic conditions is essential, because the overall impact of these interactions under varying adverse environmental conditions is lacking. This book has been designed to understand the impact of climate change, i.e., mainly salt and drought stress, on the soil microbiome and its impact on plant, yield, and the ecosphere. The book is organized into four parts: The first part reviews the impact of climate change on the diversity and richness of the soil microbiome. The second part addresses effects of climate change on plant health. The third part discusses effects on soil-plant dynamics and functionality, e.g., soil productivity. The final part deals with the effects of climate change on ecosystem functioning and also discusses potential solutions. The book will appeal to students and researchers working in the area of soil science, agriculture, molecular biology, plant physiology, and biotechnology.
Biodiversity has been a key concept in international conservation since the 1980s, yet historians have paid little attention to its origins. Uncovering its roots in tropical fieldwork and the southward expansion of U.S. empire at the turn of the twentieth century, Megan Raby details how ecologists took advantage of growing U.S. landholdings in the circum-Caribbean by establishing permanent field stations for long-term, basic tropical research. From these outposts of U.S. science, a growing community of American ""tropical biologists"" developed both the key scientific concepts and the values embedded in the modern discourse of biodiversity. Considering U.S. biological fieldwork from the era of the Spanish-American War through the anticolonial movements of the 1960s and 1970s, this study combines the history of science, environmental history, and the history of U.S.-Caribbean and Latin American relations. In doing so, Raby sheds new light on the origins of contemporary scientific and environmentalist thought and brings to the forefront a surprisingly neglected history of twentieth-century U.S. science and empire.
In Iran, climate change combined with low adaptation capacity has an unparalleled impact on eco-systems as well as human livelihoods. The Roodasht region, in the lower part of the Zayandeh Rud basin in Central Iran, is severely affected by water scarcity, desertification and land degradation. This book describes the effects this has on the environment and society, analyzes the degree of vulnerability and suggests possible ways to improve land and water management. This book provides comprehensive and interdisciplinary insights into the environmental and social situation in the region, as well as possible solutions to deal with the current challenges. Written by German and Iranian scientists, NGO staff and government officials and bridging the gap between research and practical implementation, the book not only enhances our understanding of climate change and desertification, but also raises public awareness and promotes knowledge transfer between disciplines.
An immersive blend of chicken-keeping memoir and animal welfare reporting by a journalist who accidentally became obsessed with her flock. Since first domesticating the chicken thousands of years ago, humans have become exceptionally adept at raising them for food. Yet most people rarely interact with chickens or know much about them. In Under the Henfluence, Tove Danovich explores the lives of these quirky, mysterious birds who stole her heart the moment her first box of chicks arrived at the post office. From a hatchery in Iowa to a chicken show in Ohio to a rooster rescue in Minnesota, Danovich interviews the people breeding, training, healing and, most importantly, adoring chickens. With more than 60 billion chickens living on industrial farms around the world, they're easy to dismiss as just another dinner ingredient. Yet Danovich's reporting reveals the hidden cleverness, quiet sweetness and irresistible personalities of these birds, as well as the complex human-chicken relationship that has evolved over centuries. This glimpse into the lives of backyard chickens doesn't just help us to understand chickens better - it also casts light back on ourselves and what we've ignored throughout the explosive growth of industrial agriculture. Woven with delightful and sometimes heartbreaking anecdotes from Danovich's own henhouse, Under the Henfluence proves that chickens are so much more than what they bring to the table.
This book presents a unified evolutionary framework based on three sets of metaphors that will help to consolidate discussions on evolutionary transitions. Evolution is the unifying principle of life, making identifying ways to apply evolutionary principles to tackle existence-threatening crises such as climate change crucial. A more cohesive evolutionary framework will further the discussions in this regard and also accelerate the process itself. This book lays out a framework based on three dualistic classes of metaphors - time, space, and conflict resolution. Evolutionary transitions theory shows how metaphors can help us understand selective diversification, as Darwin described with his "tree of life". Moreover, the recently proposed Stockholm paradigm demonstrates how metaphors can help shed light on the emergence of complex ecosystems that Darwin highlighted with his "tangled bank" metaphor. Taken together, these ideas offer proactive measures for coping with existential crises for humanity, such as climate change. The book will appeal to biologists, philosophers and historians alike.
The ancient inheritance that made us who we are. The ancient
inheritance that is now driving us to ruin.
Wherever there is greenery, photosynthesis is working to make oxygen, release energy, and create living matter from the raw material of sunlight, water, and carbon dioxide. Without photosynthesis, there would be an empty world, an empty sky, and a sun that does nothing more than warm the rocks and reflect off the sea. Eating the Sun is the story of a world in crisis; an appreciation of the importance of plants; a history of the earth and the feuds and fantasies of warring scientists; a celebration of how the smallest things, enzymes and pigments, influence the largest things, the oceans, the rainforests, and the fossil fuel economy. Oliver Morton offers a fascinating, lively, profound look at nature's greatest miracle and sounds a much-needed call to arms--illuminating a potential crisis of climatic chaos and explaining how we can change our situation, for better or for worse.
This book describes the multitude of interactions between plant, soil, and micro-organisms. It emphasizes on how growth and development in plants, starting from seed germination, is heavily influenced by the soil type. It describes the interactions established by plants with soil and inhabitant microbial community. The chapters describe how plants selectively promote certain microorganisms in the rhizospheric ecozone to derive multifarious benefits such as nutrient acquisition and protection from diseases. The diversity of these rhizospheric microbes and their interactions with plants largely depend on plant genotype, soils attributes, and several abiotic and biotic factors. Most of the studies concerned with plant-microbe interaction are focused on temperate regions, even though the tropical ecosystems are more diverse and need more attention. Therefore, it is crucial to understand how soil type and climatic conditions influence the plant-soil-microbes interaction in the tropics. Considering the significance of the subject, the present volume is designed to cover the most relevant aspects of rhizospheric microbial interactions in tropical ecosystems. Chapters include aspects related to the diversity of rhizospheric microbes, as well as modern tools and techniques to assess the rhizospheric microbiomes and their functional roles. The book also covers applications of rhizospheric microbes and evaluation of prospects improving agricultural practice and productivity through the use of microbiome technologies. This book will be extremely interesting to microbiologists, plant biologists, and ecologists.
This book presents a theoretical critical appraisal of the Mechanistic Theory of Human Cognition (MTHC), which is one of the most popular major theories in the contemporary field of cognitive science. It analyses and evaluates whether MTHC provides a unifying account of human cognition and its explanation.

In this sense, it provides a fresh look at more recent major theoretical debates in this area of scientific research and a rigorous analysis of one of its most central major theories. Rigorous theoretical work is integrated with objective consideration of relevant empirical evidence, making the discussions robust and clear. As a result, the book shows that MTHC provides a significant theoretical contribution for the field of cognitive science. The content is useful for those interested in theoretical and empirical issues concerning major theories in the contemporary field of cognitive science.
This book summarizes the latest research findings in the neurocircuitry of innate behaviors, covering major topics such as innate fear, aggression, feeding, reward, social interaction, parental care, spatial navigation, and sleep-wake regulation. For decades, humans have been fascinated by wild animals' instincts, like the annual two-thousand-mile migration of the monarch butterfly in North American, and the "imprint" behavior of newborn birds. Since these instincts are always displayed in stereotypical patterns in most individuals of a given species, the neural circuits processing such behaviors must be genetically hard-wired in the brain. Recently, with the development of modern techniques, including optogenetics, retrograde and anterograde virus tracing, and in vivo calcium imaging, researchers have been able to determine and dissect the specific neural circuits for many innate behaviors by selectively manipulating well-defined cell types in the brain. This book discusses recent advances in the investigation of the neural-circuit mechanisms underlying innate behaviors.

Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes. The Economics of Biological Invasions provides an important first step towards codification of the advice needed to develop decision rules, tools and protocols for the effective management of invasive biological species. This volume will be a fascinating read for researchers, academics and students in ecology, economics and environmental science with an interest in the biodiversity problem. The book will also prove to be essential reading for policymakers responsible for health, agriculture, forestry, fisheries and the environment in both developed and developing countries.
Scientific output in low- and middle-income countries is greatly challenged by numerous factors. This is particularly pronounced in sub-Saharan African countries, despite the continent being the world's second largest and second most-populous continent, currently undergoing rapid economic growth. Financial constraints and unclear areas of focus when funding is available, are among the limiting factors, with the consequence being the development of inadequate policies, especially those relating to environmental protection and conservation. This 13-chapter book is a unique piece in the field of microbiology, designed to stimulate some research areas in Africa by illustrating interesting and informative examples of the current applied research agenda in environmental microbiology in selected countries within the continent. With authors from the North, South, East and West of Africa, the book touches diverse applied methods and approaches to meet the pragmatic needs faced by environmental microbiologists in Africa. Also included are topics on viruses, bacteria (including cyanobacteria), and protozoa, and their importance in disease. Sustainable agriculture and aquaculture, and eco-friendly oil and hydrocarbon bioremediation and degradation approaches are highlighted. Microbial involvement in different common indoor (e.g., household kitchens, latrines, and hospitals) and outdoor settings including air, soil, and water habitats, and their resistance to commonly used antibiotics, are described. Hopefully, the work presented here will stimulate the need for increasing modern training and funding initiatives to prepare African microbiologists to meet the challenges they face in African universities and research laboratories.
