Arbuscular mycorrhizal fungi are obligate root symbionts that impact plant growth, productivity and competitiveness. The book integrates key information about AMF concepts, structures and functions, and the new classification of Glomeromycota, including topics about AMF history and evolution, AMF families, genus and species description, as well as a compilation about several protocols to assess AMF and how to identify them. The focus is to provide readers enough information about AMF.

This book presents a new method for assessing spatial pattern in raster land cover maps based on satellite imagery in a way that incorporates multiple pixel resolutions. This is combined with more conventional single-resolution measurements of spatial pattern and simple non-spatial land cover proportions to assess predictability of both surface water quality and ecological integrity within watersheds of the state of Pennsylvania (USA).

Volume 3 covers recent research with expanded coverage on this important area of remediation. Mycoremediation is the form of bioremediation in which fungi-based technology is used to decontaminate the environment. Fungi are among the primary saprotrophic organisms in an ecosystem, as they are efficient in the decomposition of organic matter. Wood-decay fungi, especially white rot, secretes extracellular enzymes and acids that break down lignin and cellulose. Fungi have been proven to be a very cost-effective and environmentally-friendly way for helping to remove a wide array of toxins from damaged environments or wastewater. These toxins include heavy metals, persistent organic pollutants, textile dyes, leather tanning industry chemicals and wastewater, petroleum fuels, polycyclic aromatic hydrocarbon, pharmaceuticals and personal care products, pesticides and herbicides, in land, fresh water and marine environments. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, general lipase, laccases, peroxidases and sometimes intracellular enzymes, especially the cyrochrome P450 monooxygeneses. Fungi play an important role in the biogeochemical cycling of manganese and other redox-active metals, which is related to their ability to survive radiation and other oxidative challenges. This book covers recent research with more detail on the various types of fungi and associated fungal processes used to clean up wastes and wastewaters in contaminated environments, and discusses their potential for environmental applications.

The book compiles the latest studies on microorganisms thriving in extreme conditions. Microbes have been found in extremely high and low temperatures, highly acidic to saline conditions, from deserts to the Dead sea, from hot-springs to underwater hydrothermal vents- the diversity is incredible. The various chapters highlight the microbial life and describe the mechanisms of tolerance to these harsh conditions, and show how an understanding of these phenomena can help us exploit the microbes in biotechnology. The theme of the book is highly significant since life in these environments can give vital clues about the origin and evolution of life on earth, as a lot of these conditions simulate the environment present billions of years ago. Additionally, the study of adaptation and survival of organisms in such environments can be important for finding life on other planets. This book shall be useful for students, researchers and course instructors interested in evolution, microbial adaptations and ecology in varied environments.

Large lakes are important because of their size and ecological distinctiveness as well as their economic and cultural value. Optimal management of them requires a proper understanding of anthropogenic impacts both on the lake ecosystems as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles and food-web structure, are all directly related to their size. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered. These vulnerable ecosystems often suffer from accelerated eutrophication, over-fishing, toxic contamination and invasive species. Large lakes offer socio-economic benefits and can be used in many ways, and are often areas in which economic, cultural and political interests overlap. In this book the problems regarding the present status of European large lakes and the directions of change are discussed. Threats caused by direct human impact and by climate change, protection needs and restoration measures are considered.

What if the stories of trees and people are more closely linked than we ever imagined? Winner of the World Wildlife Fund's 2020 Jan Wolkers PrizeOne of Science News's "Favorite Books of 2020" A New York Times "New and Noteworthy" BookA 2020 Woodland Book of the YearGold Winner of the 2020 Foreword INDIES Award in Ecology & EnvironmentBronze Winner of the 2021 Independent Publisher Book Award in Environment/Ecology People across the world know that to tell how old a tree is, you count its rings. Few people, however, know that research into tree rings has also made amazing contributions to our understanding of Earth's climate history and its influences on human civilization over the past 2,000 years. In her captivating book Tree Story, Valerie Trouet reveals how the seemingly simple and relatively familiar concept of counting tree rings has inspired far-reaching scientific breakthroughs that illuminate the complex interactions between nature and people. Trouet, a leading tree-ring scientist, takes us out into the field, from remote African villages to radioactive Russian forests, offering readers an insider's look at tree-ring research, a discipline known as dendrochronology. Tracing her own professional journey while exploring dendrochronology's history and applications, Trouet describes the basics of how tell-tale tree cores are collected and dated with ring-by-ring precision, explaining the unexpected and momentous insights we've gained from the resulting samples. Blending popular science, travelogue, and cultural history, Tree Story highlights exciting findings of tree-ring research, including the fate of lost pirate treasure, successful strategies for surviving California wildfire, the secret to Genghis Khan's victories, the connection between Egyptian pharaohs and volcanoes, and even the role of olives in the fall of Rome. These fascinating tales are deftly woven together to show us how dendrochronology sheds light on global climate dynamics and uncovers the clear links between humans and our leafy neighbors. Trouet delights us with her dedication to the tangible appeal of studying trees, a discipline that has taken her to austere and beautiful landscapes around the globe and has enabled scientists to solve long-pondered mysteries of Earth and its human inhabitants.

Protected areas have often been defined as the backbones of biodiversity conservation. Protected areas have often been defined as the backbones of biodiversity conservation. However, legitimate demands formulated by countries for their economic development, growing human populations, forest fragmentations, and needs of local communities for sustainable livelihoods are also pressing demands on protected areas, stringently pressuring conservation community to identify means to reconcile long term biodiversity conservation and communities' livelihoods. Hence, integrating conservation activities within the global framework of economic development of countries with high biodiversity had become part of conservation paradigms. Integrated development as a route to conservation, strict protected areas, community managed areas, etc. have been tried but resulted in debatable outcomes in many ways. The lukewarm nature of these results brought 'landscape approach' at the front of biodiversity conservation in Central Africa. Since the late 1990s the landscape approach uses large areas with different functional attributes and shifts foundational biodiversity conservation paradigms. Changes are brought to the role traditionally attributed to local communities, aligning sustainable development with conservation and stretching conservation beyond the confines of traditional protected areas. These three shifts need a holistic approach to respond to different conservation questions. There are only a few instances where the landscape experience has been scientifically documented and lessons learnt drawn into a corpus of knowledge to guide future conservation initiatives across Central Africa. To subjugate one biodiversity conservation landscape as one case study emerged as a matter of urgency to present the potential knowledge acquired throughout the landscape experiment, including leadership and management, processes tried, results (at least partially) achieved, and why such and such other process or management arrangement were been chosen among many other alternatives, etc. The challenges of the implementation of the conservation landscape approach needed also to be documented. This book responds to the majority of these questions; drawing its content from the firsthand field knowledge, it discusses these shifts and documents what has been tried, how successful (unsuccessful) it was, and what lessons learnt from these trials. Theoretical questions such as threat index, and ecological services, etc. are also discussed and gaps in knowledge are identified.

This revealing book details recent developments in the study of the relationship between sulfur and the microbial agents that affect its metabolism. In recent years, new methods have been applied to study the biochemistry and molecular biology of reactions of the global sulfur cycle, the microorganisms involved and their physiology, metabolism and ecology. These activities have uncovered fascinating new insights for the understanding of aerobic and anaerobic sulfur metabolism.

The stingless bees are one of the most diverse, attractive, fascinating, conspicuous and useful of all the insect groups of the tropical world. This is a formidable and contentious claim but I believe it can be backed up. They are fifty times more species rich than the honey bees, the other tribe of highly eusocial bees. They are ubiquitous in the tropics and thrive in tropical cities. In rural areas, they nest in a diversity of sites and are found on the flowers of a broad diversity of crop plants. Their role in natural systems is barely studied but they almost certainly deserve that hallowed title of keystone species. They are popular with the general public and are greatly appreciated in zoos and gardens. The chapters of this book provide abundant further evidence of the ecological and economic importance of stingless bees.

This book presents recent results of collaborative studies in geophysics and ecology, focusing on the relationship between the physical environment and the distribution of the marine coastal ecosystems. The study area, the Sakiyamawan-Amitoriwan nature conservation area in Iriomote Island of Japan, is the only oceanic nature conservation area in the country. The area has no access roads, and the bay perimeter is uninhabited; therefore, it preserves the natural environment with very little human impact. In addition, it has various environmental gradients such as topography and inflows from rivers with mangrove forests which affect the distribution of marine coastal ecosystems such as those containing reef-building corals, sea grasses, and hermit crabs. For these reasons, the area is one of the best places for the study of the relationship between the physical environment and the distribution of the marine coastal ecosystems, a relationship that is important for their conservation but has not been investigated fully. This book is aimed at students and researchers in the fields of oceanography and marine coastal ecology as well as general readers who are interested in coral reefs, diving, and nature conservation.

The 8th International Congress of Ecology was held in Seoul, South Korea in August 2002, and was hosted by the Ecological Society of Korea. The Congress theme was 'Ecological Issues in a Changing World', and this volume includes selected contributions to illustrate some of the important topics which were discussed during the Congress.

Problems of scale have exercised the minds of ecologists for many years, and will continue to do so into the future. This volume deals with this subject and with mathematical approaches to improve our understanding of complex ecological systems. The book also concentrates on monitoring the responses of ecosystems, especially to human impacts upon them. The importance of spatial separation of function at both the landscape and ecosystem level forms an important theme. Finally, this special book focuses on large-scale issues, discussing in particular important applied ecological problems and how these can be managed through a variety of planning processes. Many examples of major ecological problems in the mainstream ecological literature are drawn from Europe and North America. In contrast, many of the most pressing ecological problems are to be found elsewhere in the World.

This volume is composed of four parts according to scale, objectives and application of modern ecological research. Part I covers emerging concepts and models in the ecosystem complex and in the landscape. Part II. Biological responses to environmental changes: pattern and process, Part III. Ecological networking and restoration technology: theory and practice, and finally a summary of 8th INTECOL Congress and possible future directions are covered in Part IV.

This volume presents recent advances in the research on meromictic lakes and a state-of-the art overview of this area. After an introduction to the terminology and geographic distribution of meromictic lakes, three concise chapters describe their physical, chemical and biological features. The following eight chapters present case studies of more than a dozen meromictic lakes, showing the variety of physical and biochemical processes that promote meromixis. The result is a broad picture of the ecology and biochemistry of meromictic lakes in tropical and cold regions, in man-made pit lakes and euxinic marine lakes, and in freshwater as well as hypersaline lakes. In the final chapter the editors provide a synthesis of the topic and conclude that the study of meromictic lakes also offers new insights into the limnology of inland lakes. The book appeals to researchers in the fields of ecology, limnology, environmental physics and biophysics.

This book provides an overview of chemical ecology related to different ecosystems. It offers an outlook at novel directions that can be taken in chemical ecology through a molecular-ecological or eco-genomic approach. The book addresses aboveground and belowground terrestrial systems as well as aquatic systems, and the organisms involved are micro- and macro-organisms, such as plants, arthropods and mammals.

An environmental historian delves into the history, science, and philosophy of a paradoxical pursuit: the century-old quest to design natural places and create wild species. Environmental restoration is a global pursuit and a major political concern. Governments, nonprofits, private corporations, and other institutions spend billions of dollars each year to remove invasive species, build wetlands, and reintroduce species driven from their habitats. But restoration has not always been so intensively practiced. It began as the pastime of a few wildflower enthusiasts and the first practitioners of the new scientific discipline of ecology. Restoration has been a touchstone of US environmentalism since the beginning of the twentieth century. Diverging from popular ideas about preservation, which romanticized nature as an Eden to be left untouched by human hands, and conservation, the managed use of natural resources, restoration emerged as a "third way." Restorationists grappled with the deepest puzzles of human care for life on earth: How to intervene in nature for nature's own sake? What are the natural baselines that humans should aim to restore? Is it possible to design nature without destroying wildness? Laura J. Martin shows how, over time, amateur and professional ecologists, interest groups, and government agencies coalesced around a mode of environmental management that sought to respect the world-making, and even the decision-making, of other species. At the same time, restoration science reshaped material environments in ways that powerfully influenced what we understand the wild to be. In Wild by Design, restoration's past provides vital knowledge for climate change policy. But Martin also offers something more-a meditation on what it means to be wild and a call for ecological restoration that is socially just.

Yoque en el campo he nacido dig6 que mis cantos son para los unos sonidos, y para otros intencion. H. Hernandes - Martin Fierro. The period of active influence of the people on desert environments in Central Asia counts more than 2,000 years. It includes several stages of the social and the economic development of human society - from primitive culture of hunters to developed modern society with great changes of envi- ronment and "nature remaking".Heritage of the past is one of the main causes of land degradation in Central Asia.So, only historical analysis of relations between the man and the desertcould give infor- mation for awareness of desertification. What an idea have the people about the desert? In the mind of many people "desert" is identified with a sterile, lifeless and gloom land unsuitable for life. The mass media, specially the cinema sup- ports this idea. Very popular subject of many films is the death of travelers in the desert from thirst. Eventhe names of hot winds (the "gibly" inSahara, the "samum" inArabian desertand the "afganets" inCentral Asia) fill the minds of peoplewith horror. There are many legends about armies buried inthe sand,aboutflourishing oases and towns covered with sand drifts. Inthese legends the truth is mixed with fiction. But as known, "the truth isstronger than fiction".

This work assesses the issues facing biodiversity maintenance on tropical islands, and the impacts of biodiversity loss. The emphasis is on the Indo-West Pacific region, which includes many small islands where the biodiversity is under threat as a result of not only climate change and habitat destruction, but invasions by organisms previously absent from an island. The contributors are distinguished biodiversity scientists from inside and outside the region, and cover topics ranging from the state of conservation action in South-East Asia, the role of parks, and the status and threat to endemics, to impacts of oil and gas exploration and forest fragmentation. Issues needing still to be addressed, especially in relation to implications of biodiversity loss or change for the maintenance of ecosystem processes, are highlighted. The conclusions and case studies have lessons for all involved in the conservation of the biotas and ecosystems of islands. Previously published in Biodiversity and Conservation 19:2 2010

First published in 1981, Dynamics of Large Mammal Populations was written by experts from four continents and six countries. It is a collection of papers on the population dynamics of large mammals and was the first synthesis of work in the field. The book helped provide identity and coherence to an emerging field. It has become a much-sought-after book. The theoretical and empirical studies presented demonstrate the ways in which numbers of animals in large mammal populations change over time in response to a variety of factors. The studies cover a wide variety of species - including both terrestrial and marine mammals - and compare the population dynamics of various groups such as herbivores, carnivores, ungulates, cetaceans and pinnipeds. Included are species involved in controversial population management problems. Also covered are advances in managing the populations of large mammals, and advances in the theoretical basis of large mammal population dynamics. Numerous examples detail the interaction of mammals with their ecosystems. Population biologists, wildlife biologists and managers, government researchers, environmentalists and marine mammal scientists can use the information made available here as a basis for comparative research and practical applications. "The book contains an excellent mix of theoretical chapters, general overviews, and studies of specific animal speces, ranging from seals and whales to lions and elephants, taking deer, wolves, and grizzly bears along the way... But to the specialist it will be indispensable, forming as it does the only authoritative volume that deals with the population dynamics of this important group of animals." ORYX Fauna & Flora Preservation Society, July, 1983. "One immediately realizes, by skimming the citations of the different chapters, that the researchers, working on such animals as whales, bears, seals, lions, and elephants had not been talking to one another, and that this book represents something of a first in this regard." Mathematical Biosciences, 1983. "The book will be of particular interest and value to wildlife biologists faced with problems of managing wildlife resources and to people who use the resources." The Quarterly Review of Biology, 1982. "This is an excellent book. One doesn't have to be a population biologist to understand the material. Best of all, the authors are refreshingly frank about areas of ignorance in population biology and the failure of even the best simulaion models to fit the real world... To sum up, there is food for thought in this volume for every zoologist with an interest in population biology and especially for those who study large mammals." BioScience 1982. "In bringing a wealth of research effort to a wider readership, this book cannot fail to stimulate" Biometrics, 1982.

This book addresses the future of urbanisation on the Galapagos Islands from a systems, governance and design perspective with the competing parameters of liveability, economic and ecological, using the Galapagos as a laboratory for the theoretical and postulative understanding of evolving settlement and habitation. The Galapagos islands are one of the world's most examined and reported examples of a series of naturally evolving ecosystems. The biodiversity of these island ecosystems are the focus of tourism and the image across the world yet human settlement are part of the local ecology. While human intervention is limited, the islands are a distinctive context in which to consider the impact of human habitation as a part of our ecosystems. In this book, authors take the framework of complex adaptive systems (CAS) in which to model systems that grow and evolve, the relations between these various sectors change; systems that get more complex as they evolve. Tested and applied discretely in the two realms of natural and urban, for the first time this text will bring the two together in understanding options for the future of urban settlements on the Galapagos Islands and, by extension, consider how the approach can be used globally in other contexts.

What exactly is our relationship with insects? Are they more beneficial or harmful? What role do they play in the world? What are the effects of climate change: Will the number of insects continue to increase? This book discusses the beneficial and harmful effects of insects and explains their development and significance for biodiversity. This second, fully reviewed and enlarged, edition provides new insights, especially about the value of specific insect species that are generally seen as pests (e.g. ants and moths), as well as an extended chapter on the development of insects and especially their decline in different regions in the world, the industrialized countries in particular. Numerous info graphics show connections between changes in the environment due to human expansion and the number of insects and species. Studies from the US, Canada, Asia, Africa, Europe and Switzerland are used to point out the dramatic reduction of biodiversity. New tables illustrate these developments. The glossary as well as the insects index is extended, the text, tables, pictures and graphs provide even more well-rounded image. Readers will find the argumentation even more clearly and detailed.

Reviews of Environmental Contamination and Toxicology publishes authoritative reviews on the occurrence, effects, and fate of pesticide residues and other environmental contaminants. It will keep you informed of the latest significant issues by providing in-depth information in the areas of analytical chemistry, agricultural microbiology, biochemistry, human and veterinary medicine, toxicology, and food technology.

This book provides insight into the instances in which wildlife species can create problems. Some species trigger problems for human activities, but many others need humans to save them and to continue to exist. The text addresses issues faced by economists and politicians dealing with laws involving actions undertaken to resolve the problems of the interaction between humans and wildlife. Here, the words 'problematic species' are used in their broadest sense, as may be appreciated in the short introductions to the various sections. At times, the authors discuss special cases while always extending the discussion into a more general and broad vision. At others, they present real cutting-edge analysis of ecological topics and issues. The book will be of interest to biologists, ecologists and wildlife managers involved in research on wildlife, parks, and environmental management, as well as to government departments and agencies, NGOs and conservation wildlife organizations. Even those in contact with nature, such as hunters, herders, and farmers, will be able to find a great deal of important information. Specific case studies are selected from among the most significant and prevalent cases throughout the world. A total of 26 papers have been selected for this book, written by zoologists, biologists and ecologists. Many have an interdisciplinary approach, with contributions by economists, criminologists, technical specialists, and engineers.

Over the last decades, scientists have been intrigued by the fascinating organisms that inhabit extreme environments. These organisms, known as extremophiles, thrive in habitats which for other terrestrial life-forms are intolerably hostile or even lethal. Based on such technological advances, the study of extremophiles has provided, over the last few years, ground-breaking discoveries that challenge the paradigms of modern biology. In the new bioeconomy, fungi in general, play a very important role in addressing major global challenges, being instrumental for improved resource efficiency, making renewable substitutes for products from fossil resources, upgrading waste streams to valuable food and feed ingredients, counteracting life-style diseases and antibiotic resistance through strengthening the gut biota, making crop plants more robust to survive climate change conditions, and functioning as host organisms for production of new biological drugs. This range of new uses of fungi all stand on the shoulders of the efforts of mycologists over generations. The book is organized in five parts: (I) Biodiversity, Ecology, Genetics and Physiology of Extremophilic Fungi, (II) Biosynthesis of Novel Biomolecules and Extremozymes (III) Bioenergy and Biofuel synthesis, and (IV) Wastewater and biosolids treatment, and (V) Bioremediation.

This book comes after several decades of outstanding and successful research that has helped ameliorate some of the most important and controversial fisheries issues in the world a" those associated with the unwanted wastage of fish from by-catch and discarding.

The 8 chapters encompass contributions from 27 of the worlda (TM)s leading experts in by-catch reduction. They take the reader through most aspects of the field at a variety of scales and viewpoints. They examine the methodologies used to develop by-catch reduction techniques and provide new avenues for assisting and broadening such work. Case studies are provided that encompass most of the worlda (TM)s fishing techniques and regions.

Solutions developed for the most problematic fishing methods in terms of by-catch, selectivity and habitat damage are examined in significant detail in addition to ways to reduce the by-catch of charismatic species like marine mammals and sea-birds. By-catch reduction in less infamous fishing methods is also examined with chapters on recreational fishing and trapping. The book shows how the lessons learned in reducing by-catch can be applied to ameliorate emerging, broader issues concerning the impacts of fishing on entire ecosystems. Finally, the book examines the most vital phase of by-catch reduction work - its uptake and extension into fishing practices.

This book will prove an invaluable tool for any fisheries professional or lay person interested in by-catch reduction or, indeed, anyone trying to resolve a particular by-catch problem in their fishery.

Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems. Written for: All who are interested in parthenogenesis and evolutionary biology, including undergraduate and graduate students and senior researchers

The ten-year research program and the Kapalga fire experiment at CSIRO in Australia has provided a wealth of knowledge about savanna ecosystems and the critical but poorly understood role of fire. The frequent low intensity fires examined in this volume characterize fire in the tropics and are a dominant force in shaping the structure and function of tropical ecosystems. Contributors discuss fire in relation to rainfall, groundwater, and the mammals and plants in the ecology and management of ecosystems. Among the management issues addressed are: habitat management, endangered species, protection of people and property, erosion and nutrient depletion, integration of knowledge from indigenous people and western science, and atmospheric pollution from fire smoke. This book will be valuable to tropical and savanna ecologists, fire ecologists and fire managers throughout the world, whether they are interested in plants, animals, soils or in the landscape as a whole.
