Landscapes have been fundamental to the human experience world-wide and throughout time, yet how did we as human beings evolve or co-evolve with our landscapes? By answering this question, we can understand our place in the complex, ever-changing world that we inhabit. This book guides readers on a journey through the concurrent processes of change in an integrated natural-cultural history of a landscape. While outlining the general principles for global application, a richly illustrated case is offered through the Mariana Islands in the northwest tropical Pacific and furthermore situated in a larger Asia-Pacific context for a full comprehension of landscape evolution at variable scales. The author examines what happened during the first time when human beings encountered the world's Remote Oceanic environment in the Mariana Islands about 3500 years ago, followed by a continuous sequence of changing sea level, climate, water resources, forest composition, human population growth, and social dynamics. This book provides a high-resolution and long-term view of the complexities of landscape evolution that affect all of us today.

Echinacea - Herbal Medicine with a Wild History (Paperback, Softcover reprint of the original 1st ed. 2016): Kelly Kindscher Echinacea - Herbal Medicine with a Wild History (Paperback, Softcover reprint of the original 1st ed. 2016)

R3,706 Discovery Miles 37 060 Ships in 10 - 15 working days

This book provides an in-depth analysis of one the of most popular medicinal plants-Echinacea a species that is native to only the US and Canada. There are nine Echinacea species and several roots and above-ground portions of these showy wildflowers have been used in herbal medicine as an immune stimulant and to reduce one's chances of catching a cold. Considerable medical research supports these claims. The most popular species and the primary one wild-harvested is the one native to the Great Plains, Echinacea angustifolia. It has a long history of use, including being both historically and currently the most widely-used medicinal plant by any of the Great Plains Native Americans. The importance of this species is described by the editor with a few key contributors chosen to relate the important facets of the story of this interesting plant: Echinacea's biology, ecology, medicinal uses, markets, production and harvest, along with population biology, legal protections, ethnobotany, and history. The US Forest Service has expressed concern about the conservation status of Echinacea species on their lands, especially on the National Grasslands and National Forest units in the northern Great Plains. Overall, the future status of Echinacea, as an important medicinal plant and in the wild is not grim, but this book provides a clear perspective of why both cultivated and wild-harvested Echinacea will continue to be available to consumers without threatening the remaining populations.

R6,693 Discovery Miles 66 930 Ships in 10 - 15 working days

This book highlights perspectives, insights, and data in the coupled fields of aquatic microbial ecology and biogeochemistry when viewed through the lens of collaborative duos - dual career couples. Their synergy and collaborative interactions have contributed substantially to our contemporary understanding of pattern, process and dynamics. This is thus a book by dual career couples about dual scientific processes. The papers herein represent wide-ranging topics, from the processes that structure microbial diversity to nitrogen and photosynthesis metabolism, to dynamics of changing ecosystems and processes and dynamics in individual ecosystems. In all, these papers take us from the Arctic to Africa, from the Arabian Sea to Australia, from small lakes in Maine and Yellowstone hot vents to the Sargasso Sea, and in the process provide analyses that make us think about the structure and function of all of these systems in the aquatic realm. This book is useful not only for the depth and breadth of knowledge conveyed in its chapters, but serves to guide dual career couples faced with the great challenges only they face. Great teams do make great science.

Sociality in Bats (Paperback, Softcover reprint of the original 1st ed. 2016): Jorge Ortega Sociality in Bats (Paperback, Softcover reprint of the original 1st ed. 2016)

Laura E. Taylor, Patrick T Hurley
R3,917 Discovery Miles 39 170 Ships in 10 - 15 working days

This book is about politics and planning outside of cities, where urban political economy and planning theories do not account for the resilience of places that are no longer rural and where local communities work hard to keep from ever becoming urban. By examining exurbia as a type of place that is no longer simply rural or only tied to the economies of global resources (e.g., mining, forestry, and agriculture), we explore how changing landscapes are planned and designed not to be urban, that is, to look, function, and feel different from cities and suburbs in spite of new home development and real estate speculation. The book's authors contend that exurbia is defined by the persistence of rural economies, the conservation of rural character, and protection of natural ecological systems, all of which are critical components of the contentious local politics that seek to limit growth. Comparative political ecology is used as an organizing concept throughout the book to describe the nature of exurban areas in the U.S. and Australia, although exurbs are common to many countries. The essays each describe distinctive case studies, with each chapter using the key concepts of competing rural capitalisms and uneven environmental management to describe the politics of exurban change. This systematic analysis makes the processes of exurban change easier to see and understand. Based on these case studies, seven characteristics of exurban places are identified: rural character, access, local economic change, ideologies of nature, changes in land management, coalition-building, and land-use planning. This book will be of interest to those who study planning, conservation, and land development issues, especially in areas of high natural amenity or environmental value. There is no political ecology book quite like this-neither one solely focused on cases from the developed world (in this case the United States and Australia), nor one that specifically harnesses different case studies from multiple areas to develop a central organizing perspective of landscape change.

Mark Everard
R1,970 Discovery Miles 19 700 Ships in 10 - 15 working days

This book explores humanity's relationship with the natural world throughout evolutionary history, and the need to reorient this onto a symbiotic basis. It integrates the themes of natural and artificial selection, the characteristics of historic 'revolutions', and directed versus random change. Inspiring community-based projects, mainly from the developing world, show how ecosystem regeneration uplifts human livelihoods in a positively reinforcing cycle, embodying lessons germane to co-creating a Symbiocene era wherein humanity's substantial influence (the Anthropocene) achieves increasing symbiosis with the natural processes shaping the former Holocene epoch. The Ecosystems Revolution provides practical, positive examples, highlighting the attainability of an 'ecosystems revolution'.

James D. Blande, Robert Glinwood
R7,507 Discovery Miles 75 070 Ships in 10 - 15 working days

This book provides an overview of the intricacies of plant communication via volatile chemicals. Plants produce an extraordinarily vast array of chemicals, which provide community members with detailed information about the producer's identity, physiology and phenology. Volatile organic chemicals, either as individual compounds or complex chemical blends, are a communication medium operating between plants and any organism able to detect the compounds and respond. The ecological and evolutionary origins of particular interactions between plants and the greater community have been, and will continue to be, strenuously debated. However, it is clear that chemicals, and particularly volatile chemicals, constitute a medium akin to a linguistic tool. As well as possessing a rich chemical vocabulary, plants are known to detect and respond to chemical cues. These cues can originate from neighbouring plants, or other associated community members. This book begins with chapters on the complexity of chemical messages, provides a broad perspective on a range of ecological interactions mediated by volatile chemicals, and extends to cutting edge developments on the detection of chemicals by plants.

Maria Nita
R2,957 Discovery Miles 29 570 Ships in 10 - 15 working days

This book presents an ethnographic study of environmental Christian networks involved in the climate and transition towns movements. Maria Nita examines the ways in which green Christians engage with their communities and networks, as well as other activist networks in the broader green movement. The book interrogates key categories in the field of religious studies which intersect activist concerns, including spirituality, community, and ritual. In this sociological exploration the author uses existing research tools, such as discourse analysis, and proposes new theoretical models for the investigation of network expansion, religious identity, and relationality through ritual. Nita examines the mechanisms underlying the greening of religion and thus offers an in-depth analysis of prayers, rituals, and religious practices, such as praying through painting, fasting for the planet, and sharing the green Eucharist in or with nature.

R5,581 Discovery Miles 55 810 Ships in 10 - 15 working days

This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host's capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host's protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.

R5,668 Discovery Miles 56 680 Ships in 10 - 15 working days

This volume summarizes recent advances in environmental microbiology by providing fascinating insights into the diversity of microbial life that exists on our planet. The first two chapters present theoretical perspectives that help to consolidate our understanding of evolution as an adaptive process by which the niche and habitat of each species develop in a manner that interconnects individual components of an ecosystem. This results in communities that function by simultaneously coordinating their metabolic and physiologic actions. The third contribution addresses the fossil record of microorganisms, and the subsequent chapters then introduce the microbial life that currently exists in various terrestrial and aquatic ecosystems. Coverage of the geosphere addresses endolithic organisms, life in caves and the deep continental biosphere, including how subsurface microbial life may impact spent nuclear fuel repositories. The discussion of the hydrosphere includes hypersaline environments and arctic food chains. By better understanding examples from the micro biosphere, we can elucidate the many ways in which the niches of different species, both large and small, interconnect within the overlapping habitats of this world, which is governed by its microorganisms.

R7,994 Discovery Miles 79 940 Ships in 10 - 15 working days

In any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other's survival and provide sustenance in stressful environments. Agro-ecosystems in many regions around the globe are affected by high temperatures, soil salinity/alkalinity, low pH and metal toxicity. High salinity and severe draught are other major constraints affecting agricultural practices and also plants in the wild. A major limiting factor affecting global agricultural productivity is environmental stresses. Apart from decreasing yield, they also have a devastating impact on plant growth. Plants battle with various kind of stresses with the help of symbiotic associations with the rhizospheric microbes. Naturally occuring plant-microbe interactions facilitate the survival of plants under these stressful conditions. The rhizosphere consists of several groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes that assists plants in coping with multiple stresses and also promote plant growth. These efficient microbes support the stress physiology of the plants and can be extremely useful in solving agricultural as well food- security problems. This book provides a detailed, holistic description of plant and microbe interaction. It elucidates various mechanisms of nutrient management, stress tolerance and enhanced crop productivity in the rhizosphere, discussing The rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health. Divided into two volumes, the book addresses fundamentals, applications as well as research trends and new prospects for agricultural sustainability. Volume 1: Stress Management and Agricultural Sustainability, includes chapters offering a broad overview of plant stress management with the help of microbes. It also highlights the contribution of enzymatic and molecular events occurring in the rhizosphere due to plant microbe interactions, which in turn help in the biological control of plant disease and pest attacks. Various examples of plant microbe interaction in rhizospheric soil are elaborated to facilitate the development of efficient indigenous microbial consortia to enhance food and nutritional security. Providing a comprehensive information source on microbes and their role in agricultural and soil sustainability, this timely research book is of particular interest to students, academics and researchers working in the fields of microbiology, soil microbiology, biotechnology, agronomy, and the plant protection sciences, as well as for policy makers in the area of food security and sustainable agriculture.

R3,786 Discovery Miles 37 860 Ships in 10 - 15 working days

This second edition textbook offers an expanded conceptual synthesis of microbial ecology with plant and animal ecology. Drawing on examples from the biology of microorganisms and macroorganisms, this textbook provides a much-needed interdisciplinary approach to ecology. The focus is the individual organism and comparisons are made along six axes: genetic variation, nutritional mode, size, growth, life cycle, and influence of the environment. When it was published in 1991, the first edition of Comparative Ecology of Microorganisms and Macroorganisms was unique in its attempt to clearly compare fundamental ecology across the gamut of size. The explosion of molecular biology and the application of its techniques to microbiology and organismal biology have particularly demonstrated the need for interdisciplinary understanding. This updated and expanded edition remains unique. It treats the same topics at greater depth and includes an exhaustive compilation of both the most recent relevant literature in microbial ecology and plant/animal ecology, as well as the early research papers that shaped the concepts and theories discussed. Among the completely updated topics in the book are phylogenetic systematics, search algorithms and optimal foraging theory, comparative metabolism, the origins of life and evolution of multicellularity, and the evolution of life cycles. From Reviews of the First Edition: "John Andrews has succeeded admirably in building a bridge that is accessible to all ecologists." -Ecology "I recommend this book to all ecologists. It is a thoughtful attempt to integrate ideas from, and develop common themes for, two fields of ecology that should not have become fragmented." -American Scientist "Such a synthesis is long past due, and it is shameful that ecologists (both big and little) have been so parochial." -The Quarterly Review of Biology

This volume critically reviews all previously published work of parasites that interact with krill (order Euphausiacea) updating misconceptions and summarizing the diversity of epibionts, ectoparasites, mesoparasites and endoparasites that interact with these crustaceans. As far as we know, there is a lack of books about parasites of marine crustaceans not targeted to fisheries and aquaculture. Thus, this would be the most complete and integrative monograph of parasites of marine zooplankton and micro nektonic organisms worldwide. Krill form immense aggregations and serve as food for multiple planktonic and nektonic predators playing a crucial role in pelagic food web. Besides, several species are also used for human consumption. For these reasons there is a growing concern about the health issues that krill parasites may impose on other species, including us. This book provides a comprehensive review of parasites of a crustacean order that can extrapolate to potential parasites in other crustacean taxa worldwide.

Soils are neither good nor bad, but some have inherent or acquired characteristics that may or may not suit our intended use. Unsuitable characteristics are considered to be soil problems, soil constraints or soil limitations. Only twelve percent of global land is right for agricultural production without much limitation. Some soils have severe limitations for crop production. These soils are so called 'problem soils'. Many of them do not have enough fertility to be productive; some are arid and saline; some are very sandy and dry; and some are wet and waterlogged for most of the growing season. The global demand for food, wood, fuel, fiber, medicine and other plant products for the 7.2 billion current world population has created such an immense pressure on global soil resources that even the most fertile soils are losing their productive capacity. We are being compelled to bring more and more unsuitable or marginally suitable soils under cultivation. Unless innovative and integrated soil, crop and environmental management practices are adopted for their improvement and sustainable use, further degradation is inevitable. This book, Management of Soil Problems, identifies the problems and discusses management options in a smooth and reader-friendly style. It will be useful for students and professionals of soil science, agriculture, forestry, geography and environmental sciences.

R3,466 Discovery Miles 34 660 Ships in 10 - 15 working days

In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.

In its second volume, this book aims to link the academic research with development in the real world and provide a historical and institutional background that can enrich more formal research. The first section will include an assessment of the evolution and the state of the nascent second-generation biofuel as well as a perspective on the evolution of corn ethanol and sugarcane ethanol in Brazil. It will also include a historical and institutional background on the biofuel industry in Brazil that has global lessons, and later, provide a technical overview of major analytical tools used to assess the economic, land use and greenhouse gas implications of biofuel policies at a regional and global level. Additionally, the book analyzes the various drivers for land use change both at a micro-economic level and at a macro-economic level. It presents studies that apply regional and global economic models to examine the effects of biofuel policies in the US, EU and Brazil on regional and global land use, on food and fuel prices and greenhouse gas emissions. These papers illustrate the use of partial and general equilibrium modeling approaches to simulate the effects of various biofuel policies, and includes studies showing the effects of risk aversion, time preferences and liquidity constraints on farmers decision to grow energy crops for biofuel production. By presenting the tools of lifecycle analysis for assessing the direct greenhouse gas intensity of biofuels, this handbook investigates the types of indirect or market mediated effects that can offset or strengthen these direct effects. It will include tools to assess the direct and indirect effects of biofuel production on greenhouse gas emissions in the US and Brazil, and ultimately provide a comprehensive background to understand the state of biofuel in the present and how to analyze their implication.

Ryan details the modern research techniques today's professionals use to study mammals wherever they are found. Ideal for any mammalogy or wildlife biology course, this clear and practical guide aids students by getting them outside to study mammals in their natural environments. Twenty comprehensive chapters cover skull and tooth identification, radio and satellite GPS tracking, phylogeny construction, mark and recapture techniques, camera trapping, museum specimen preparation, optimal foraging, and DNA extraction, among other topics.
