The present volume by the author is based on the outcome of extensive explorations in the Himalayas for more than a decade. It incorporates the original research findings along with that based on literature survey. It is intended to provide a comprehensive account of an important group of fungi which has a direct bearing on wood industry and forest ecosystem besides commercial application in bioremediation and pollution control. It is the first step in providing the mycologists with consolidated, systematically up-to-date and illustrative monograph of wood-rotting fungi of Himalayas. Every year the students of the post graduate colleges and universities particularly Indian sub-continent go in for fungal forays to collect fungi which forms part of their course curriculum. This book will serve as a field manual for identification. The book has more than 240 color photographs and 123 plates of camera lucida drawings covering all the fungi which have been reported till-to-date from the study area.

Biodiversity and the Precautionary Principle - Risk, Uncertainty and Practice in Conservation and Sustainable Use (Paperback):... Biodiversity and the Precautionary Principle - Risk, Uncertainty and Practice in Conservation and Sustainable Use (Paperback)
Rosie Cooney, Barney Dickson
R2,045 Discovery Miles 20 450 Ships in 10 - 15 working days

* The first book to examine the application of the Precautionary Principle -- the most important and controversial approach to biodiversity and natural resource management worldwide * Comprehensive case studies from Australia, New Zealand, the USA, East and Central Africa, India, the Philippines, Vietnam, Argentina, Uruguay and Fiji, including marine environments and forests * Written by top practitioners in association with the main international conservation organizationsGreat uncertainty typically surrounds decisions and management actions in the conservation of biodiversity and natural resource management, and yet there are risks of serious and irreversible harm for both biodiversity and the humans that rely on it. The Precautionary Principle underlies all international conservation efforts and entails acting to avoid serious or irreversible environmental harm, despite lack of scientific certainty as to the likelihood, magnitude, or cause of harm.This book, the first to examine the application of the Precautionary Principle to conservation, analyzes how it has been applied in themanagement of biodiversity, including the impact on forests products and aquaculture, as well as wildlife and livelihoods. The book also examines how power, equity, and science intertwine in the Principle. Evidence is drawn from a vast range of countries and the book provides guidelines for applying the Precautionary Principle in all international contexts for the conservation and sustainable management of biodiversity and natural resources.

Nature's Matrix - Linking Agriculture, Biodiversity Conservation and Food Sovereignty (Paperback, 2nd edition): Ivette... Nature's Matrix - Linking Agriculture, Biodiversity Conservation and Food Sovereignty (Paperback, 2nd edition)
Ivette Perfecto, John Vandermeer, Angus Wright
R1,365 Discovery Miles 13 650 Ships in 9 - 17 working days

When first published in 2009, Nature's Matrix set out a radical new approach to the conservation of biodiversity. This new edition pushes the frontier of the biodiversity/agriculture debate further, making an even stronger case for the need to transform agriculture and support small- and medium-scale agroecology and food sovereignty. In the first edition, the authors set out a radical new approach to the conservation of biodiversity. This is based on the concept of a landscape as a matrix of diverse, small-scale agricultural ecosystems, providing opportunities to enhance conservation under the stewardship of local farmers. This contrasts with the alternative view of industrial-scale farms and large protected areas which exclude local people. However, since then the debate around conservation and agriculture has developed significantly and this is reflected in this updated second edition. The text is thoroughly revised, including: a reorganization of chapters with new and timely topics introduced, updates to the discussion of agroecology and food sovereignty, bringing it in line with the current debates, greater coverage of the role of agroecology, in particular agroforestry, as an important component of climate change adaptation and mitigation, highlighting recent studies on the role of intensive agriculture in climate change and loss of biodiversity, and more attention given to the discussion of land sparing versus land sharing. By integrating the ecological aspects of agriculture and conservation biology, with a political and social analysis as well as historical perspective, the book continues to set a progressive agenda and appeals to a wide range of students and professionals.

'An original, wide-ranging and carefully researched book ... contains important lessons for humanity.' Mark Cocker, The Spectator A fascinating insight into climate change biology around the globe, as well as in our own backyards. Hurricane Lizards and Plastic Squid is the first major book by a biologist to focus on the fascinating story of how the natural world is adjusting, adapting, and sometimes measurably evolving in response to climate change. Lyrical and thought-provoking, this book broadens the climate focus from humans to the wider lattice of life. Bestselling nature writer Thor Hanson - author of Buzz (a Radio 4 'Book of the Week') - shows us how Caribbean lizards have grown larger toe pads to grip trees more tightly during frequent hurricanes; and how the 'plasticity' of squid has allowed them to change their body size and breeding habits to cope with altered sea temperatures. Plants and animals have a great deal to teach us about the nature of what comes next, because for many of them, and also for many of us, that world is already here.

Landscape Agroecology (Paperback): Paul Wojtkowski Landscape Agroecology (Paperback)
Paul Wojtkowski
R1,615 Discovery Miles 16 150 Ships in 10 - 15 working days

Learn how the principles and practices of landscape agroecology can help to overcome drought, flooding, poor soil, damaging winds, plant diseases, plant-eating insects, and more! Examining the concepts, conventions, and components that underlie the ecology of human-managed landscapes, this is the first book to address landscape agroecology. Incorporating ideas from agroecology, forestry, agronomy, agroforestry, landscape ecology, and environmental science, Landscape Agroecology is a comprehensive look at a cutting-edge topic. From the author: Farm or forestry landscapes can be designed to address any number of objectives. Commonly, the focus is entirely on production with few, if any, secondary goals. These landscapes typically achieve their purpose but are not entirely in harmony with nature. Landscape agroecology offers the same potential for productivity, but also focuses on sustainability and environmental friendliness as strong secondary objectives. While the idea of formulating landscapes for specific purposes is comparatively new, countless examples exist where landscape modifications have been made to inhospitable areas in order to overcome the natural obstacles that hamper crop growth. This book illuminates the principles behind these triumphs, bringing this local knowledge into the mainstream. Landscape Agroecology will familiarize you with the concepts and terminology needed to understand this exciting new field: complementarityusually defined in terms of plant-plant growthexpanded to include the rural countryside desirable agroecosystems propertieswhat an agroecosystem needs in order to overcome landscape stresses such as drought, flooding, insect infestation, etc. agrotechnologiesthe classification of agroecosystems based on visual characteristics and the land-use problems addressed cultural agroecologywhat we can learn from the superior land-use techniques of various societies and cultures, and how these ideas can be brought into the mainstream cultural motifculturally related land-use patterns that are openly manifested in the landscape Essential for university/college libraries and for research stations as well as professors and students of agroecology, this book will be referred to again and again. In addition to basic agroecological concepts, chapters in this essential book address the management of wind, water, and pests; biodiversity; physical and temporal patterns; principal, auxiliary, and temporal agrotechnologies, and much more. For professors and students in environmental science, this book offers many previously un-dicussed alternatives for resolving the earth's environmental dilemmas. Photographs, tables, figures, and illustrations help make important points easy to access and understand.

Adaptation and Fitness in Animal Populations - Evolutionary and Breeding Perspectives on Genetic Resource Management... Adaptation and Fitness in Animal Populations - Evolutionary and Breeding Perspectives on Genetic Resource Management (Hardcover, 2009 ed.)
Julius Van Der Werf, Hans-Ulrich Graser, Richard Frankham, Cedric Gondro
R5,284 Discovery Miles 52 840 Ships in 18 - 22 working days

Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production.

Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use.

Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources.

This book had an ambitious goal in bringing together a sample of the world s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

R1,690 Discovery Miles 16 900 Ships in 9 - 17 working days

The ONLY textbook available on marine mammal physiology, a core topic in Marine Science undergrad teaching Builds on the unique overall theme 'How would you design a marine mammal?' which focuses on what an undergrad student would actually want to know. What would they ask? So rather than "What are the biochemical differences between marine and terrestrial mammals?" the book addresses "How can marine mammals dive for such a long time?" or "How do they stay warm in such cold water?" Organises the Table of Contents into common 'real' student questions. The book thus centres around the point of view of the student. This makes it accessible and student-focused. Consistency across all chapters Provides consistent Power Point slides that teachers can use when they don't know the field well AND that students can use as study guides. Offers Study Questions and future thinking/implications questions. A Driving Question for each chapter is highlighted in a box. A concluding chapter ties up loose ends and consolidates the driving questions from the individual chapters. Contains the contributions of well-respected, prominent scientists in the field. Author bios for each chapter showcase diversity in contributor pool. Focuses on physiological adaptations of marine mammals and connects them with the ecological context, including anthropogenic impacts. Discusses differences that might exist by type of marine mammal, development questions, and behavioral issues.

R2,500 R2,118 Discovery Miles 21 180 Save R382 (15%) Ships in 10 - 15 working days

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

Philip Ashmole, Myrtle Ashmole
R552 Discovery Miles 5 520 Ships in 9 - 17 working days

Carrifran Wildwood was the brainchild of local people who mourned the lack of natural habitats and decided to act. When Borders Forest Trust was founded the Wildwood became the Trust's first large land-based project, and after 20 years of work it has become an inspirational example of ecological restoration. Removal of sheep and goats and planting 700,000 trees launched the return of native woodland and moorland, transforming degraded hill land into something akin to its pristine, vibrant, carbon-absorbing state, teeming with plants, animals and fungi, alive with birdsong and the sound of the wind in the trees. The 40 contributors vividly describe all the challenges of carrying forward bold initiatives requiring close cooperation with local communities as well as funders, authorities, landowners and partners. A core part of the book is devoted to how nature asserts itself when given a chance. It includes 'before and after' surveys, describes vegetation changes - some of them unpredicted - following removal of sheep, cattle and feral goats; unique documentation of the dramatic changes in bird populations during the 20-year transformation of Carrifran valley from denuded land to a restored mosaic of woodland and moorland habitats; discussion of the gradual development of a diverse range of invertebrate animals; and descriptions of the rich communities of fungi and mosses, many of them newly-recorded in the area. The book concludes with discussion of the role of restoration ecology in addressing the biodiversity crisis and climate change. This is the extraordinary story of how a group of motivated people can revive nature at a landscape scale.

"A literary work with a life all its own, and without exaggeration, it is a masterpiece. . . . Far from being a simple narrative, the book discusses the incredible contribution each tree makes to the planet, where and how to plant them, and what environment they are most complementary to."
---Monika Carless, "EcoFarm & Garden"

"In prose as rich as the forest itself, Diana Beresford-Kroeger sees trees for all their attributes---as providers of clean air, clean water, food, shelter, and beauty---and places them squarely at the center of a complex web of nature that is crucial to all species including man."
---Roger C. Dower, President, Forest Stewardship Council-United States

Nothing on earth compares to the Boreal forest to maintain life on this planet. The vast primeval forest stretches across the northern regions of the world, from northern Canada and Alaska to northern Europe, Russia, China, and Japan. Boreal species can be found in cooler temperate climates everywhere, including Michigan and other cool areas of the United States, and some outliers are even found in the tropics. The circumpolar runoff from the Boreal enriches the seas with nutrients in the spring. The evergreens of the Boreal act as a passive ground coolant. And the needles of the evergreens and the trichomal hairs of the deciduous trees comb the air free of harmful minute particulate pollution.

"Arboretum Borealis" does for the northern forests of the world what Arboretum America did for the forests of North America. Diana Beresford-Kroeger further describes how each Boreal tree group relates to its natural environment and how these specific trees can be used to promote health or to counteract the effects of pollution and global warming.

"Arboretum Borealis" reveals the fascinating history of these trees in Native American culture, including their medicinal uses. Finally, Beresford-Kroeger offers practical design ideas and tips---where to plant these trees, what season they look best in, and what native plants complement them.

Diana Beresford-Kroeger is a botanist; medical and agricultural researcher; lecturer; and self-defined "renegade scientist" in the fields of classical botany, medical biochemistry, organic chemistry, and nuclear chemistry. She is the author of "Arboretum America" and lives in Ontario, Canada.

Entropy and Diversity - The Axiomatic Approach (Paperback): Tom Leinster Entropy and Diversity - The Axiomatic Approach (Paperback)
Tom Leinster
R1,255 Discovery Miles 12 550 Ships in 10 - 15 working days

The global biodiversity crisis is one of humanity's most urgent problems, but even quantifying biological diversity is a difficult mathematical and conceptual challenge. This book brings new mathematical rigour to the ongoing debate. It was born of research in category theory, is given strength by information theory, and is fed by the ancient field of functional equations. It applies the power of the axiomatic method to a biological problem of pressing concern, but it also presents new theorems that stand up as mathematics in their own right, independently of any application. The question 'what is diversity?' has surprising mathematical depth, and this book covers a wide breadth of mathematics, from functional equations to geometric measure theory, from probability theory to number theory. Despite this range, the mathematical prerequisites are few: the main narrative thread of this book requires no more than an undergraduate course in analysis.

This book examines the critical issue of environmental pollutants produced by the textiles industry. Comprised of contributions from environmental scientists and materials and textiles scientists, this edited volume addresses the environmental impact of microplastics, with a particular focus on microfibres released by textiles into marine and freshwater environments. The chapters in Part I offer environmental perspectives focusing on the measurement of microplastics in the environment, their ingestion by small plankton and larger filter feeders, the effects of consuming microplastics, and the role of microplastics as a vector for transferring toxic contaminants in food webs. Written by environmental and material scientists, the chapters in Part II present potential solutions to the problem of microplastics released from textiles, discussing parameters of influence, water treatment, degradation in aquatic environments, textile end-of-life management, textile manufacturing and laundry, and possible policy measures. This is a much needed volume which brings together in one place environmental research with technical solutions in order to provide a cohesive and practical approach to mitigating and preventing environmental pollution from the textiles industry going forward. This book will be of great interest to students and scholars of environmental conservation and management, environmental pollution and environmental chemistry and toxicology, sustainability, as well as students and scholars of material and textiles science, textile engineering and sustainable manufacturing.
