Applications of Physiological Ecology to Forest Management (Hardcover): J.J. Landsberg, S.T. Gower Applications of Physiological Ecology to Forest Management (Hardcover)
J.J. Landsberg, S.T. Gower; Volume editing by Jacques Roy
R2,540 Discovery Miles 25 400 Ships in 12 - 19 working days

Forest management is a complex process that now incorporates information obtained from many sources. It is increasingly obvious that the physiological status of the trees in a forest has a dramatic impact on the likely success of any particular management strategy. Indeed, models described in this book that deal with forest productivity and sustainability require physiological information. This information can only be obtained from an understanding of the basic biological mechanisms and processes that contribute to individual tree growth. This valuable book illustrates that physiological ecology is a fundamental element of proficient forest management.

Offering a unique and systematic assessment of South African ecology in unprecedented detail, the book could serve as a model for future vegetation surveys of forests not only in Africa, but also around the globe.

Biointensive Integrated Pest Management in Horticultural Ecosystems (Hardcover, 2014 ed.): P. Parvatha Reddy Biointensive Integrated Pest Management in Horticultural Ecosystems (Hardcover, 2014 ed.)
P. Parvatha Reddy
R6,802 Discovery Miles 68 020 Ships in 12 - 19 working days

Through Green Revolution in late 1960s, India achieved self-sufficiency in food production, but still the country has not achieved self-sufficiency in production of horticultural crops. Most of the growth in food production during the green revolution period is attributed to the use of higher levels of fertilizers and pesticides which are continuing to destroy stable traditional ecosystems. The challenge before the crop protection scientist is to increase yields from the existing land without harming the environment and resource base. This can be achieved by adopting eco-friendly Biointensive Integrated Pest Management (BIPM) strategy.

BIPM incorporates ecological and economic factors into agricultural system design and decision making, and addresses public concerns about environmental quality and food safety. The benefits of implementing BIPM can include reduced chemical input costs, reduced on-farm and off-farm environmental impacts, and more effective and sustainable pest management. An ecology-based IPM has the potential of decreasing inputs of fuel, machinery, and synthetic chemicals-all of which are energy intensive and increasingly costly in terms of financial and environmental impact. Such reductions will benefit the grower and society.

The present book deals with the most recent biointensive integrated approaches for pest management utilizing components such as bioagents predators, parasitoids and pathogens (bacteria, fungi, viruses)], botanicals (biofumigation, oil cakes, FYM, compost, crop residues, green manuring and other organic amendments), arbuscular mycorrhizal fungi, physical methods (hot water treatment of planting material, soil solarization), cultural methods (crop rotation, summer ploughing, fallowing, intercropping, pruning, mulching, spacing, planting date, trap cropping, "etc."), biorational chemicals (pheromones) and resistant cultivars. This book can serve as a useful reference to policy makers, research and extension workers, practicing farmers and students. The material can also be used for teaching post-graduate courses."

Filippo Schilleci, Vincenzo Todaro, Francesca Lotta
R2,851 Discovery Miles 28 510 Ships in 10 - 15 working days

This book explores and outlines the reference theoretical basis of ecological networks within the international debate, focusing on how protected areas should no longer be considered as the sum of different components but rather as a network. The various European, transnational and national models of ecological networks/connections are analyzed on the basis of a detailed, updated study of relevant documents. The complex picture that emerges shows a wide range of reticular-ecological models within European plans and programs, but also many non-integrated experiences. The book subsequently examines the regulation of ecological networks/connections within planning instruments, explaining the critical points and referring to different ecological network models and specific local realities. Lastly, the book addresses two Italian case studies regarding the different normative and planning frameworks, both at a national and regional level, and demonstrating not only how ecological networks/connections can be structured within plans, but also how these networks/connections represent the core element of territory development and preservation. As such, it provides an essential tool for containing habitat fragmentation, offering a new perspective that integrates theoretical approaches and methods with planning models and the lessons learned from local applications.

Mangroves and seagrasses form extensive and highly productive ecosystems that are both biologically diverse and economically valuable. This book, now in its third edition and fully updated throughout, continues to provide a current and comprehensive introduction to all aspects of the biology and ecology of mangroves and seagrasses. Using a global range of examples and case studies, it describes the unique adaptations of these plants to their exacting environments; the rich and diverse communities of organisms that depend on mangrove forests and seagrass meadows (including tree-climbing shrimps, synchronously flashing fireflies, and 'gardening' seacows); the links between mangrove, seagrass, and other habitats; and the evolution, biodiversity, and biogeography of mangroves and seagrasses. The economic value of mangroves and seagrasses is also discussed, including approaches to rational management of these vital resources and techniques for the restoration of degraded habitats. A final chapter, new to this edition, examines the potential effects of global climate change including sea level rise. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these fascinating aquatic ecosystems although pollution, conservation, and experimental aspects are also considered. This accessible textbook assumes no previous knowledge of mangrove or seagrass ecology and is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers.

R4,655 Discovery Miles 46 550 Ships in 10 - 15 working days

The research category of the landscape ecology, which researches the structure, functions, and the spatio-temporal changes of the ecological landscapes, has now been contributing to the human life and the shifts of the socio-economic paradigm. Global warming has been influencing the universal life patterns of the mankind which have been maintained in the past several hundreds of years. And it has been having the influences on the international social problems and economic problems. Although the diverse plans for adapting to the climate changes have been the topics of the conservations among the ecologists internationally, it is the reality that the speed of the changes of the environment has been quicker than the time it takes to complete the solutions. In order to maintain the sustainable earth and the sustainable society, the role of the landscape ecology has been coming to the fore. Especially, the theories and the methodologies of the landscape ecology have been applied to the multidisciplinary researches by going beyond the research category of ecology, including the maximization of the efficiencies of the land spaces, the management of the ecological space (habitats) in which the biological diversity can be maintained, the utilization of the resources that are absolutely needed by the human beings (Here, it is compressed to water, energy, and food), etc. and until reaching the human society. It is considered that, to that extent, the utilizations and the applications of the landscape ecology are very much needed for the diagnoses and the evaluations of the global environmental problems which have been proceeded with rapidly in the modernity. This book is not comprised of any general remarks that explain the theories and the methods of the landscape ecology. Already, based on the basic theories of the landscape ecology, the writers have conducted the investigations on the farm villages, the cities, and the coastal ecosystems. And, through the space analyses and interpretations, the structure and functions of the landscapes were analyzed. Of course, in this book, too, the diverse ecosystems and the landscape ecological methodologies regarding the land use have been presented. However, the core of this book focuses more on what role the landscape ecology must play for the materialization of a sustainable society in the future. At the farm villages, the sustainable agriculture will be presented, and, at the cities, the discussions on the green networks and the energies will be proceeded with. Also, regarding the coasts and the seas, a thesis on the safety of the life zones of the residents adjacent to the sea and on the conservation of the island ecosystems will be presented. The sustainable society is a system that is formed by having the sustainable development as a basis. It is considered to be one aspect within a kind of a sustainable process with regard to which the natural world and the human world coexist and are in a symbiotic relationship harmoniously. In order to maintain the biodiversity, the reasonable adjustments of the human activities, like the use of the resources, are absolutely needed. Without the biological resources, the cultural diversity of the human beings, too, cannot exist. Consequentially, recently and internationally, there are a lot of the case examples that express the biocultural diversity by linking the biological diversity with the cultural diversity. In this book, the role of the landscape ecology as an academic link which can connect the two possible, if possible, is highly expected. It is, indeed, the biocultural landscape. It can be said that this concept, also, is the interconnection of the multidisciplinary spaces that must be dealt with in the modern landscape ecology. Through this book, it is intended to present a new directionality which can contribute to the sustainable society at the same time as the organization of the theories and the methods of the landscape ecology.

Mongolia is an expansive land-locked country, tilted by tectonic forces to the North, that experiences extremes of continental climate. Moisture-carrying wind currents are scarce so that the land has extended highs and lows in its environment. Culturally the people are mostly nomadic, having been sustained for centuries by an economy based on domestic livestock grazing. There is a saying that, As the noses go, so goes Mongolia', referring to the domesticated grazing noses of sheep, goats, camels, yaks or horses, and wild ungulates such as gazelles. The vast fenceless steppes of Mongolia furnish the vegetation for grazing. With such extremes in climate it is clear that the vegetation must be resilient and dynamic to cope with the dictates of its extremely harsh environments. Pollen profiles from lakes, plant macrofossils and other data over the last 15,000 years show the dynamic nature of Mongolian vegetation. Currently Mongolian society is experiencing much human-driven economic development which increases pressure on its vegetation. The Great Khural Laws of 1995 forcefully addressed such environmental concerns with the expanded establishment of National Reserves and Parks. But continued effort and vigilance must be expended to insure that Mongolian society will continue to be sustained by its vegetation. This book highlights work such as conserving and restoring plant diversity in various ecosystems and makes recommendations for sustaining the vegetation basis of the nomadic Mongolian society.

R4,398 Discovery Miles 43 980 Ships in 10 - 15 working days

Natural and agro-ecosystems are frequently exposed to natural or synthetic substances, which, while they have no direct nutritional value or significance in metabolism, may negatively affect plant functioning. These, xenobiotics, may originate from both natural (fires, volcano eruptions, soil or rock erosion, biodegradation) and anthropogenic (air and soil pollution, herbicides) sources. And, while affected plants have only a limited number of possibilities for avoiding accumulation of these compounds, they do exhibit several enzymatic reactions for detoxification including oxidation, reduction, hydrolysis and conjugation reactions. In agro-ecosystems in particular these mechanisms have great significance in relation to herbicide detoxification and tolerance. In this volume an international group of experts present an overview of the nature and distribution of organic xenobiotics, including their uptake, effects on plant functioning and detoxification mechanisms. The particular significance of glutathione S-transferases in bio-indication and bio-monitoring, and in the detoxification of volatile organic air pollutants and herbicides is evaluated, and their potential significance in phytoremediation and bioaccumulation will be discussed. This volume will be of interest to a wide audience, from graduate students to senior researchers in a wide range of disciplines including plant ecology, plant biochemistry, agriculture and environmental management. It will also be of practical interest to environmentalists, policy makers and resource managers.

The continuously growing human population along the world s coasts will exacerbate the impact of human activities on all coastal environments. Restoration activities will therefore become increasingly important. In particular, sandy shores and coastal dunes will require significant restoration efforts because they are preferred sites for human settlement, industrial and urban development and tourism.

With this book experts in the field present a comprehensive review of restoration studies and activities, where successful and failed studies or approaches from around the world are contrasted and compared. A major asset the book provides is a compendium of studies showing that coastal dune restoration has many definitions and thus leads to many different actions.

This volume addresses those with an interest in conservation ecology and biology, coastal dune dynamics and geomorphology, and coastal management who are seeking information on the different strategies for coastal dune restoration applied in different regions of the world. Finally, it will be a valuable resource for coastal scientists and planners, as well as for local and state officials, residents of coastal communities, environmental advocates and developers.

R4,371 Discovery Miles 43 710 Ships in 10 - 15 working days

The aim of this book is to elucidate the role of forests as part of a landscape in the life of people. Most landscapes today are cultural landscapes that are influenced by human activity and that in turn have a profound effect on our understanding of and identification with a place. The book proposes that a better understanding of the bond between people and forests as integrated part of a landscape may be helpful in landscape planning, and may contribute to the discussion of changes in forest cover which has been motivated by land use changes, rural development and the global climate debate. To this end, people's perception of forest landscapes, the reasons for different perceptions, and future perspectives are discussed. Given the wide range of forest landscapes, and cultural perspectives which exist across the world, the book focuses on Europe as a test case to explore the various relationships between society, culture, forests and landscapes. It looks at historical evidence of the impacts of people on forests and vice versa, explores the current factors affecting people's physical and emotional comfort in forest landscapes, and looks ahead to how changes in forest cover may alter the present relationships of people to forests. Drawing together a diverse literature and combining the expertise of natural and social scientists, this book will form a valuable reference for students and researchers working in the fields of landscape ecology and landscape architecture, geography, social science, environmental psychology or environmental history. It will also be of interest to researchers, government agencies and practitioners with an interest in issues such as sustainable forest management, sustainable tourism, reserve management, urban planning and environmental interpretation.

Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.

R5,656 Discovery Miles 56 560 Ships in 10 - 15 working days

This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The ? rst treatise on the ? ora of Egypt, by Petrus Forsskal, was published in 1775. Records of the Egyptian ? ora made during the Napoleonic expedition to Egypt (1778-1801) were provided by A. R. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be recognized. The ? rst was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836-1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xeroph- ism. These two traditions were maintained and expanded in further phases of e- logical development associated with the establishment of the Egyptian University in 1925 (now the University of Cairo). The ? rst professor of botany was the Swedish Gunnar Tackholm (1925-1929). He died young, and his wife Vivi Tackholm devoted her life to studying the ? ora of Egypt and gave leadership and inspiration to plant taxonomists and plant ecologists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W.

Well designed, constructed and maintained reinforced or prestressed concrete structures are generally very durable. In aggressive environments though, corrosion of steel can be a significant problem and structures such as bridges, industrial buildings and those subjected to marine conditions can be particularly at risk. Over the last decade there has been fast growing interest in reinforcing concrete with fibre reinforced plastic materials which cannot rust or deteriorate like steel. This proceedings of the Second International RILEM Symposium on the subject, held in Ghent, August 1995, deals with a wide range of non-metallic materials and opens up possibilities of lighter, more durable structures. The contributions by leading international researchers and design engineers are divided into parts covering material development and properties, bond behaviour of FRP elements, structural behaviour of reinforced and prestressed concrete members, rehabilitation and strengthening, and design methods and applications. This complete overview of knowledge on the subject will provide an essential update for structural engineers, concrete specialists and researchers into materials and structures.

Flora of North America brings together for the first time ever in a concise and easy to understand format information on all of the plants growing spontaneously in North America north of Mexico. Volume 24 of Flora North America is one of two volumes on grasses to be published in this series (Volume 25, though it follows sequentially, was published in 2003). Together they will provide a comprehensive, authoritative, illustrated account of this important group of plants. Most of the species treated are either native to North America north of Mexico or are introduced species that are now established in the region, but there are many that do not fit into these categories. Among the additional species are several that the USDA has identified as major weed threats; and others that are known only as cultivated plants, some being cultivated for their ornamental value, others as sources for human food or animal forage. For instance, volume 24 includes such ecologically important genera as Elymus (wheatgrasses), Poa (bluegrasses), and Festuca (fescues), economically important species such as Triticum (wheat), Hordeum (barley), Oryza (rice), and Zizania (wild rice), several ornamental species, including some bamboos, and noxious weeds such as Elymus repens (quackgrass), and Bromus tectorum (cheatgrass).
The volume includes identification keys, descriptions, line drawings, and ecological characteristics for each of the species; distribution maps for the native and established species; and a list of commonly encountered synonyms for the accepted names. The treatments, each of which has been extensively reviewed, are based on a combination of original observations and critical review of the literature.

Water is a paramount factor in determining the distribution of species on a global basis. The responses and adaptations of a species to water stress are critical for its success in any environmental niche. The deserts of the Middle East provide an excellent example of the harsh conditions to which plants are subjected.This volume elucidates the adaptations of these plants in order to sustain their life and reproduce to continue their survival. Topics covered include climate aridity and topographic influence on plant life in the deserts, the role of plants in the lives of the Bedouins, the concept of adaptation, its purposes and causes, adaptations that promote increased water uptake and reduction of water output, as well as those which help the plants to tolerate and/or resist the drought, escaping drought and adaptation to desiccation, and the mechanisms by which halophytes can tolerate and/or resist salinity.

The public's attitude toward air pollution in the United States evolved substantially during the 1960s. One of the results of the nation's emerging environmental ethic was the creation of the U. S. Environmental Protection Agency (EPA) in December of 1970. Prior to this time, research was focused on the impacts of air pollution on human health and welfare and was largely conducted by several federal research agencies, which included the Department of Health, Education, and Welfare; the National Oceanic and Atmospheric Administration; and the U. S. Department of Agricul ture. After the creation of the EPA, much of this work was consolidated in one regulatory agency, which resulted in periodic evaluations of the various effects of atmospheric pollution on human health, materials, agriculture, and forest ecosystems.
