Sunday Times Bestseller 'A paradigm-smashing chronicle of joyous entanglement' Charles Foster Waterstones Non-Fiction Book of the Month (September) Are trees social beings? How do trees live? Do they feel pain or have awareness of their surroundings? In The Hidden Life of Trees Peter Wohlleben makes the case that the forest is a social network. He draws on groundbreaking scientific discoveries to describe how trees are like human families: tree parents live together with their children, communicate with them, support them as they grow, share nutrients with those who are sick or struggling, and even warn each other of impending dangers. Wohlleben also shares his deep love of woods and forests, explaining the amazing processes of life, death and regeneration he has observed in his woodland. A walk in the woods will never be the same again.

R1,308 Discovery Miles 13 080 Ships in 10 - 15 working days

Historical ecology is a research framework which draws upon diverse evidence to trace complex, long-term relationships between humanity and Earth. With roots in anthropology, archaeology, ecology and paleoecology, geography, and landscape and heritage management, historical ecology applies a practical and holistic perspective to the study of change. Furthermore, it plays an important role in both fundamental research and in developing future strategies for integrated, equitable landscape management. The framework presented in this volume covers critical issues, including: practicing transdisciplinarity, the need for understanding interactions between human societies and ecosystem processes, the future of regions and the role of history and memory in a changing world. Including many examples of co-developed research, Issues and Concepts in Historical Ecology provides a platform for collaboration across disciplines and aims to equip researchers, policy-makers, funders, and communities to make decisions that can help to construct an inclusive and resilient future for humanity.

Graph theory can be applied to ecological questions in many ways, and more insights can be gained by expanding the range of graph theoretical concepts applied to a specific system. But how do you know which methods might be used? And what do you do with the graph once it has been obtained? This book provides a broad introduction to the application of graph theory in different ecological systems, providing practical guidance for researchers in ecology and related fields. Readers are guided through the creation of an appropriate graph for the system being studied, including the application of spatial, spatio-temporal, and more abstract structural process graphs. Simple figures accompany the explanations to add clarity, and a broad range of ecological phenomena from many ecological systems are covered. This is the ideal book for graduate students and researchers looking to apply graph theoretical methods in their work.

Towns, Ecology, and the Land (Paperback): Richard T.T. Forman Towns, Ecology, and the Land (Paperback)
Richard T.T. Forman
R1,109 Discovery Miles 11 090 Ships in 10 - 15 working days

Towns and villages are sometimes viewed as minor, even quaint, spots, whereas this book boldly reconceptualizes these places as important dynamic environmental 'hotspots'. Multitudes of towns and villages with nearly half the world's population characterize perhaps half the global land surface. The book's pages feature ecological patterns, processes, and change, as well as human dimensions, both within towns and in strong connections and effects on surrounding agricultural land, forest land, and arid land. Towns, small to large, and villages are examined with spatial and cultural lenses. Ecological dimensions - water, soil and air systems, together with habitats, plants, wildlife and biodiversity - are highlighted. A concluding section presents concepts for making better towns and better land. From a pioneer in both landscape ecology and urban ecology, this highly international town ecology book opens an important frontier for researchers, students, professors, and professionals including environmental, town, and conservation planners.

Plant Conservation - The Role of Habitat Restoration (Paperback): Sergei Volis Plant Conservation - The Role of Habitat Restoration (Paperback)
Sergei Volis
R1,028 Discovery Miles 10 280 Ships in 10 - 15 working days

The rate of species and natural habitat loss across our planet is steadily accelerating. This book argues that existing practises of plant conservation are inadequate and firmly supports the placement of ecological restoration at the cornerstone of biodiversity conservation. The author unifies different aspects of conservation into one coherent concept, including natural area protection, ex situ conservation and in situ interventions through either population management or ecological restoration. Assisted colonization, experimentation, and utilization of threatened plant species are raised as crucial elements in restoration, with partly novel ecosystems being among its major target areas. Covering a wide spectrum of plant conservation examples, and offering practical methodologies alongside the theoretical context, this is a vital resource for students, research scientists and practitioners in conservation biology and restoration ecology.

Introduction to Plant Fossils (Paperback, 2nd Revised edition): Christopher J. Cleal, Barry A. Thomas Introduction to Plant Fossils (Paperback, 2nd Revised edition)
Christopher J. Cleal, Barry A. Thomas
R1,034 Discovery Miles 10 340 Ships in 10 - 15 working days

Plant remains can preserve a critical part of history of life on Earth. While telling the fascinating evolutionary story of plants and vegetation across the last 500 million years, this book also crucially offers non-specialists a practical guide to studying, dealing with and interpreting plant fossils. It shows how various techniques can be used to reveal the secrets of plant fossils and how to identify common types, such as compressions and impressions. Incorporating the concepts of evolutionary floras, this second edition includes revised data on all main plant groups, the latest approaches to naming plant fossils using fossil-taxa and techniques such as tomography. With extensive illustrations of plant fossils and living plants, the book encourages readers to think of fossils as once-living organisms. It is written for students on introductory or intermediate courses in palaeobotany, palaeontology, plant evolutionary biology and plant science, and for amateurs interested in studying plant fossils.

Evolutionary Dynamics of Plant-Pathogen Interactions (Paperback): Jeremy J. Burdon, Anna-Liisa Laine Evolutionary Dynamics of Plant-Pathogen Interactions (Paperback)
Jeremy J. Burdon, Anna-Liisa Laine
R1,065 Discovery Miles 10 650 Ships in 10 - 15 working days

This volume sits at the cross-roads of a number of areas of scientific interest that, in the past, have largely kept themselves separate - agriculture, forestry, population genetics, ecology, conservation biology, genomics and the protection of plant genetic resources. Yet these areas also have a lot of common interests and increasingly these independent lines of inquiry are tending to coalesce into a more comprehensive view of the complexity of plant-pathogen associations and their ecological and evolutionary dynamics. This interdisciplinary source provides a comprehensive overview of this changing situation by identifying the role of pathogens in shaping plant populations, species and communities, tackling the issue of the increasing importance of invasive and newly emerging diseases and giving broader recognition to the fundamental importance of the influence of space and time (as manifest in the metapopulation concept) in driving epidemiological and co-evolutionary trajectories.

R828 R776 Discovery Miles 7 760 Save R52 (6%) Ships in 10 - 15 working days

How do you record the wildlife in a wood? This book explains ways to record the flora and fauna found in woodland and outlines the sources you can use to find out more about the history and management of an area. Whether you have just a few hours, or a few years, there are examples that you can follow to find out more about this important habitat. Woods include some of the richest terrestrial wildlife sites in Britain, but some are under threat and many are neglected, such that they are not as rich as they might be. If we are to protect them or increase their diversity we need first to know what species they contain, how they have come to be as they are, to understand how they fit into the wider landscape. Conservation surveys are the bedrock on which subsequent protection and management action is based. There is not one method that will be right for all situations and needs, so the methods discussed range from what one can find out online, to what can be seen on a general walk round a wood, to the insights that can come from more detailed survey and monitoring approaches. Fast-evolving techniques such as eDNA surveys and the use of LiDAR are touched on.

Reaching for the Sun - How Plants Work (Paperback, 2nd Revised edition): John King Reaching for the Sun - How Plants Work (Paperback, 2nd Revised edition)
John King
R858 Discovery Miles 8 580 Ships in 10 - 15 working days

From their ability to use energy from sunlight to make their own food, to combating attacks from diseases and predators, plants have evolved an amazing range of life-sustaining strategies. Written with the non-specialist in mind, John King's lively natural history explains how plants function, from how they gain energy and nutrition to how they grow, develop and ultimately die. New to this edition is a section devoted to plants and the environment, exploring how problems created by human activities, such as global warming, pollution of land, water and air, and increasing ocean acidity, are impacting on the lives of plants. King's narrative provides a simple, highly readable introduction, with boxes in each chapter offering additional or more advanced material for readers seeking more detail. He concludes that despite the challenges posed by growing environmental perils, plants will continue to dominate our planet.

Peter J. Hogarth
R1,262 Discovery Miles 12 620 Ships in 10 - 15 working days

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.

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."

Mark D. Hunter
R1,483 R1,122 Discovery Miles 11 220 Save R361 (24%) Ships in 10 - 15 working days

The dazzling variation in plant chemistry is a primary mediator of trophic interactions, including herbivory, predation, parasitism, and disease. At the same time, such interactions feed back to influence spatial and temporal variation in the chemistry of plants. In this book, Mark Hunter provides a novel approach to linking the trophic interactions of organisms with the cycling of nutrients in ecosystems. Hunter introduces the concept of the "phytochemical landscape"--the shifting spatial and temporal mosaic of plant chemistry that serves as the nexus between trophic interactions and nutrient dynamics. He shows how plant chemistry is both a cause and consequence of trophic interactions, and how it also mediates ecosystem processes such as nutrient cycling. Nutrients and organic molecules in plant tissues affect decomposition rates and the fluxes of elements such as carbon, nitrogen, and phosphorus. The availability of these same nutrients influences the chemistry of cells and tissues that plants produce. In combination, these feedback routes generate pathways by which trophic interactions influence nutrient dynamics and vice versa, mediated through plant chemistry. Hunter provides evidence from terrestrial and aquatic systems for each of these pathways, and describes how a focus on the phytochemical landscape enables us to better understand and manage the ecosystems in which we live. Essential reading for students and researchers alike, this book offers an integrated approach to population-, community-, and ecosystem-level ecological processes.

R1,230 Discovery Miles 12 300 Ships in 10 - 15 working days

This advanced textbook explores the intriguing flora and plant ecology of the Middle East, framed by a changing desert landscape, global climate change, and the arc of human history. This vast region has been largely under-recognized, under-studied, and certainly under-published, due in part to the challenges posed to research by political disputes and human conflict, and a treatise on the subject is now timely. The book integrates Middle Eastern plant geography and its major drivers (geo-tectonics, seed and fruit dispersal, plant functional types, etc.) with the principles of plant ecology. The authors include the many specialized adaptations to desert and dryland ecosystems including succulence, water-conserving photosynthesis, and a remarkable range of other life history strategies. They explore the formation of 'climate relicts', and describe the long history of domestication in the region together with the many reciprocal effects of agriculture on plant ecology. The book concludes by discussing conservation in the region, highlighting five regional biodiversity hotspots where the challenges of desertification, habitat loss, and other threats to plant biodiversity are particularly acute. Plant Ecology in the Middle East is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both undergraduate and graduate students taking courses in plant ecology, evolution, systematics, biodiversity, and conservation, and will also be of interest and use to a professional audience of botanists, conservation biologists, and practitioners working in dryland ecosystems.

This book explores the sustainability aspect of organic and conventional farming systems, which is commonly categorized into three sub-aspects: social, environmental and economic. The social structure of a given area, organic friendly technologies, soil properties, crop diversification and income are the elements chosen for comparison, and are analyzed using descriptive and statistical methods. In addition, the book assesses the current status of the local organic market in Nepal and field experiments involving the use of various organic means to achieve better production for selected vegetables. Determining the benefits and/or challenges of organic and conventional farming is important to determining the most viable type of farming in the long term, but can be greatly impacted by a given area's specific characteristics (social, environmental, political, etc.), which is why this study focuses on a specific location: the Chitwan district of Nepal, where group conversion to organic farming has existed alongside conventional farming for years. This book offers a useful guide for both practitioners and academic researchers who are interested in organic farming and food security, particularly in developing countries.

While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management."

Futoshi Nakamura
R3,114 Discovery Miles 31 140 Ships in 10 - 15 working days

This book focuses on Blakiston's fish owl and the red-crowned crane as umbrella species. Healthy river, riparian and wetland ecosystems are necessary to maintain the populations of the two species. Both species have been revered by people since ancient times, but both are currently listed as endangered because of their small population sizes. The population decline of the two species can be mainly attributed to the degradation of the natural riparian and wetland habitats, which is associated with land use development. The populations of the two species are now recovering in Japan due to recent conservation and reproduction efforts, but the genetic diversity of the two species are still low due to previous bottleneck effects. To develop conservation and dispersal plans to establish the species over the East Asian mainland and on the island of Hokkaido, basic information, such as their regional distribution, genetic diversity, food availability, reproductive traits, and nesting, breeding, rearing, and commuting habitat, is essential. The intensive, collaborative studies conducted in Japan and Russia has clarified the status quo and the ecology of the two species. This is the first book that comprehensively compiles the above information for the mainland and island populations. In addition, it verifies their suitability as umbrella species of an ecosystem and the possibility of their future population expansion, taking into account changes in land use in Hokkaido, which is about to experience a dramatic decline in human population. As such, the book provides valuable information for students who wish to learn about these beautiful symbolic creatures, for NGOs engaged in conservation activities, and for managers who are involved in creating conservation plans and implementing restoration projects.
