Whale sharks are the largest of all fishes, fascinating for comparative studies of all manner of biological fields, including functional anatomy, growth, metabolism, movement ecology, behavior and physiology. These gentle ocean giants have captured the interest of scientists and the imagination of the public, yet their future is uncertain. The conservation status of whale sharks was upgraded to Endangered on the IUCN Red List and the species faces a range of intense threats from human activities. Can these iconic living animals, who have survived for millions of years, survive us? Written by the world's leading experts in whale shark biology, ecology, and conservation, Whale Sharks: Biology, Ecology and Conservation is the first definitive volume about the world's biggest fish. Chapters include discussions of satellite-linked tags, used to track whale shark movements; genetic sequencing, to examine evolutionary adaptations; even the use of underwater ultrasound units to investigate the species' reproduction. The editors hope that by collating what is known, they can make it easier for future researchers, conservationists, and resource managers to fill some of the remaining knowledge gaps, and provide the information they need to join the team. As you work your way through this book, we hope that you will develop a sense of awe and marvel at all of our good fortune to share the ocean, and the planet, with this utterly extraordinary species.

This book presents some results on selected taxa in the Himalayan region (mainly Nepal), pinpoints the threats to their survival and suggests ways how to avoid their extinction. Most chapters are based on graduate research projects - relatively long-term field studies. The data presented here can be a good source of updated information on the subject and will prove to be a very useful reference in future studies of Himalayan biodiversity. They also tend to pinpoint the existing gaps in our knowledge of this region. All the chapters are based on recent trends of biodiversity and conservation vision, so the book can be a potential alternative to the existing relatively older books with outdated vision and information. Its main goal, however, is to disseminate the information about biodiversity conservation problems in the Himalayan region among the people in the developed world.

The Sunday Times Bestseller A new, fully updated narrative edition of David Attenborough's seminal biography of our world, The Living Planet. Nowhere on our planet is devoid of life. Plants and animals thrive or survive within every extreme of climate and habitat that it offers. Single species, and often whole communities adapt to make the most of ice cap and tundra, forest and plain, desert, ocean and volcano. These adaptations can be truly extraordinary: fish that walk or lay eggs on leaves in mid-air; snakes that fly; flightless birds that graze like deer; and bears that grow hair on the soles of their feet. In The Living Planet, David Attenborough's searching eye, unfailing curiosity and infectious enthusiasm explain and illuminate the intricate lives of the these colonies, from the lonely heights of the Himalayas to the wild creatures that have established themselves in the most recent of environments, the city. By the end of this book it is difficult to say which is the more astonishing - the ingenuity with which individual species contrive a living, or the complexity of their interdependence on each other and on the habitations provided by our planet. In this new edition, the author, with the help of zoologist Matthew Cobb, has added all the most up-to-date discoveries of ecology and biology, as well as a full-colour 64-page photography section. He also addresses the urgent issues facing our living planet: climate change, pollution and mass extinction of species.

This book offers an in-depth description of different groups of microbes (i.e. bacteria, protozoa, fungi and viruses) that exist in the rumen microbial community, and offers an overview of rumen microbiology, the rumen microbial ecosystem of domesticated ruminants, and rumen microbial diversity. It provides the latest concepts on rumen microbiology for scholars, researchers and teachers of animal and veterinary sciences. With this goal in mind, throughout the text we focus on specific areas related to the biology and complex interactions of the microbes in rumen, integrating significant key issues in each respective area. We also discuss rumen manipulation with plant secondary metabolites, microbial feed additives, utilization of organic acids, selective inhibition of harmful rumen microbes, and 'omics' approaches to manipulating rumen microbial functions. A section on the exploration and exploitation of rumen microbes addresses topics including the current state of knowledge on rumen metagenomics, rumen: an underutilized niche for industrially important enzymes and ruminal fermentations to produce fuels. We next turn our attention to commercial applications of rumen microbial enzymes and to the molecular characterization of euryarcheal communities within an anaerobic digester. A section on intestinal disorders and rumen microbes covers acidosis in cattle, urea/ ammonia metabolism in the rumen and nitrate/ nitrite toxicity in ruminant diets. Last, the future prospects of rumen microbiology are examined, based on the latest developments in this area. In summary, the book offers a highly systematic collection of essential content on rumen microbiology.

Originally published in 1987, Conservation of Ecosystems and Species examines conservation as a major world issue for governments, industrialists and the general public. The need for conservation has become more urgent as human activity continues to encroach upon the remaining natural ecosystems of our planet. This book examines a wide range of conservation issues and explains the scientific reasons why conservation of ecosystems and species is important, not merely for its own sake, but for the future of humanity. It charts the development of conservation policy around the concept and understanding of the ecosystem. The roles of the planner, the industrialist and the politician in the development of a conservation policy are described.

This book combines several ideas and philosophies and provides a detailed discussion on the value addition of fruits, vegetables, spices, plantation crops, floricultural crops and in forestry. Separate chapters address the packaging, preservation, drying, dehydration, total quality management and supply chain management of horticultural crops. The book explains value addition as a process of increasing the economic value and consumer appeal of a commodity with special reference to horticultural crops. Each chapter focuses on a specific area, exploring value addition as a production/ marketing strategy driven by customer needs and preferences. But, as such, it is also a more creative field, calling for more imagination than calculated, routine work. Value is added to the particular produce item when the product is still available when the season is out and the demand for the product exceeds the available supply. Value addition is an important factor in the growth and development of the horticultural sector, both in India and around the world. But very little information is available on this particular aspect of horticulture. Albert Einstein famously said, "Try not to become a man of success, but rather try to become a man of value." This message is not only true for those people who want to make more of themselves, but also for those who want their creation or product in any form to excel. And it certainly applies to horticultural crops, which are extremely perishable. It is true that loss reduction is normally less costly than equivalent increases in production. The loss of fresh produce can be minimized by adopting different processing and preservation techniques to convert the fresh vegetables into suitable value-added and diversified products, which will help to reduce the market glut during harvest season. Value-added processed products are products that can be obtained from main products and by-products after some sort of processing and subsequently marketed for an increased profit margin. Generally speaking, value-added products indicate that for the same volume of primary products, a higher price is achieved by means of processing, packing, enhancing the quality or other such methods. The integrated approach from harvesting to the delivery into the hands of the consumer, if handled properly, can add value to fresh produce on the market. But most of the fresh produce has a limited life, although it can be stored at appropriate temperature and relative humidity for the same time. If such produce is processed just after harvesting, it adds value and stabilizes the processed products for a longer time. Preparing processed products will provide more variety to consumers and improve the taste and other sensory properties of food. This will also promote their fortification with nutrients that are lacking in fresh produce. By adopting suitable methods for processing and value addition, the shelf life of fresh produce can be increased manifold, which supports their availability year-round to a wider spectrum of consumers on both the domestic and international market. With increased urbanization, rising middle class purchasing power, changing food habits and a decline in making preserved products in individual homes, there is now a higher demand for industry-made products on the domestic market. In spite of all these aspects, only 1-2.2% of the total produce is processed in developing countries, as compared to 40-83% in developed countries. The horticultural export industry offers an important source of employment for developing countries. For instance, horticulture accounts for 30% of India's agricultural GDP from 8.5% of cropped area. India is the primary producer of spices, second largest producer of fruits and vegetables and holds a prominent position with regard to most plantation crops in the world. The cultivation of horticultural crops is substantially more labor-intensive than growing cereal crops and offers more post-harvest opportunities for the development of value-added products. This book offers a valuable guide for students of horticulture, as well as a comprehensive resource for educators, scientists, industrial personnel, amateur growers and farmers.

A pioneering work of ecological philosophy that has been acclaimed since its first publication A highly original and engaging linking of philosophy and science and Spinoza and Einstein, resulting in a new theory of ecological ethics Even more topical and relevant now than its first publication Includes a substantial new Introduction by the author

Originally published in 1989 Social Philosophy and Ecological Scarcity presents a systematic study of the implications of ecological scarcity for social philosophy. The book argues for a new social philosophy based on a conception of the 'good society' and the 'good life' which makes fewer, rather than more demands on scarce ecological resources. The book shows that the two major competing social philosophies in modern philosophical thought - the bourgeois liberal and the state socialist - are both forms of capitalism. Despite their obvious differences, they both pursue the logic of capitalism, of ever-increasing accumulation, growth and consumption. This pursuit is carried out by means of modern science and its technology, which assume that Nature's resources are inexhaustible and can be exploited to meet infinite human wants or needs, ignoring ecological scarcity. The recognition of ecological scarcity would lead to a social philosophy, based on a frugal mode of socialism which has more affinities with the social visions of Fourier and Morris than with that of Marx. Their theories, far from being too 'utopian', are shown as more 'realistic' and less 'fantastic' than either bourgeois capitalism or state capitalism based on the Marxist model.

Originally published in 1981 Historical Plant Geography is an introductory treatment of historical plant geography and stresses the basic theoretical frame of the subject. The book is about neither the study of vegetation nor the concept of the ecosystem, instead focusing on the much older tradition concerned with analysing the geographical distribution of individual species and natural plant groups. Important areas are discussed, such as global plate tectonics and sea-floor spreading, plant maps are introduced and there is a basic treatment of recent advances in plant taxonomy. The book will appeal to students and academics of geography, botany, ecology and environmental sciences.

Originally published in 1992 Economics for the Wilds argues that an economics that properly values the resources of the wilds offers the best long-term security for their future. Most of the world's wilds have, in fact, always been utilized by local societies who have managed their resources sustainably, and one important guarantee for their preservation is therefore the continued participation of those communities and an adequate reward to them for their management. The book looks at the complexity and global nature of the issues, at the application of economics to the wilds and at the policies for their conservation and sustainable management which then result. It also examines specific forms of utilization of wild species and habitats, both sustainable and unsustainable, and including community-based development, tourism, the use of rainforest products, poaching and the impact of conservation on wildlife use. The book concludes that a comprehensive utilization strategy for wild resources is needed to ensure their continued existence and the continued flow of benefits from them.

Originally published in 1990, The Biogeography of the British Isles is devoted to the biogeography of the British Isles and surrounding shelf seas. Bringing together a wealth of diverse information, it is thoroughly referenced and well illustrated, and will be invaluable to students of geography, environmental science, ecology, botany, and zoology. The book traces the development of British biogeography over the last two centuries, examining key topics such as ecosystems, habitats, and niches in the context of plant and animal distribution. The book gives a detailed account of the development of biogeographical mapping and recording systems, and describes modern-day distributions, both in the countryside and in urban areas against the backcloth of human activities.

Spoil to Soil: Mine Site Rehabilitation and Revegetation presents both fundamental and practical aspects of remediation and revegetation of mine sites. Through three major themes, it examines characterization of mine site spoils; remediation of chemical, physical and biological constraints of mine site spoils, including post mine-site land-use practices; and revegetation of remediated mine site spoils. Each theme includes chapters featuring case studies involving mine sites around the world. The final section focuses specifically on case studies with successful mine site rehabilitation. The book provides a narrative of how inert spoil can be converted to live soil. Instructive illustrations show mine sites before and after rehabilitation. The purpose of this book is to provide students, scientists, and professional personnel in the mining industry sensible, science-based information needed to rehabilitate sustainably areas disturbed by mining activities. This book is suitable for undergraduate and graduate students majoring in environmental, earth, and soil sciences; environmental and soil scientists; and mine site environmental engineers and regulators.

Ecological Restoration and Management of Longleaf Pine Forests is a timely synthesis of the current understanding of the natural dynamics and processes in longleaf pine ecosystems. This book beautifully illustrates how incorporation of basic ecosystem knowledge and an understanding of socioeconomic realities shed new light on established paradigms and their application for restoration and management. Unique for its holistic ecological focus, rather than a more traditional silvicultural approach, the book highlights the importance of multi-faceted actions that robustly integrate forest and wildlife conservation at landscape scales, and merge ecological with socioeconomic objectives for effective conservation of the longleaf pine ecosystem.

The Handbook of Australasian Biogeography is the most comprehensive overview of the biogeography of Australasian plants, fungi and animal taxa in a single volume. This volume is unique in its coverage of marine, freshwater, terrestrial, and subterranean taxa. It is an essential publication for anyone studying or researching Australasian biogeography. The book contains biogeographic reviews of all major plant, animal and fungal groups in Australasia by experts in the field, including a strong emphasis on invertebrates, algae, fungi and subterranean taxa. It discusses how Australasia is different from the rest of the world and what other areas share its history and biota.

Biogeography and Evolution in New Zealand provides the first in-depth treatment of the biogeography of New Zealand, a region that has been a place of long-enduring interest to ecologists, evolutionary scientists, geographers, geologists, and scientists in related disciplines. It serves as a key addition to the contemporary discussion on regionalization-how is New Zealand different from the rest of the world? With what other areas does it share its geology, history, and biota? Do new molecular phylogenies show that New Zealand may be seen as a biological 'parallel universe' within global evolution?

Beach-spawning fishes from exotic locations on most continents of the world provide spectacular examples of extreme adaptations during the most vulnerable life cycle stages. The beauty, intriguing biology, and importance of these charismatic fishes at the interface of marine and terrestrial ecosystems have inspired numerous scientific studies. Adaptations of behavior, physiology, development, and ecology are gathered together for the first time in this book. Beach-Spawning Fishes: Reproduction in an Endangered Ecosystem is a comprehensive guide to beach spawning, a charismatic animal behavior that is seen in a surprising number of teleost species. This unexpected form of reproduction provides a window into the ecology of coastal areas, the behaviors and physiology necessary for fishes and their eggs to adapt to terrestrial conditions, and the threats and challenges for conservation and management. Beach-spawning species include important forage fishes such as the capelin, exotic fishes such as the fugu puffer, and the spectacular midnight runs of the California grunion.

Marine eutrophication has been recognized as a global problem with adverse effects on ecosystem's health and the economies of coastal states. Most conventions regarding marine environmental protection of Regional Seas have given priority to eutrophication and relevant management practices. This book presents a global perspective of eutrophication in most of the Regional Seas, including the legal framework, assessment and management practices. Information on ecosystem's impact as well as an outline of the methods used for assessing eutrophication is also provided. This volume will be useful to research students, marine scientists and policy makers working in marine environmental management. Key Features: Contributes to the understanding of the eutrophication processes and problems Presents an extensive account of the data analysis methods used for the quantitative assessment of eutrophication Looks the eutrophication status of the main regional seas Provides information on eutrophication politics and measures to mitigate eutrophication

This book highlights the latest advances in the science and practice of using ecosystem services to inform decisions for economic development in the context of the developing countries. The development of the ecosystem services paradigm has enhanced our understanding of natural capital as an indispensable form of capital asset along with produced and human capital. This book addresses what could be the possible pathways to mainstream natural capital assets into development policies and what is currently known about the economic values of ecosystem services. A series of innovative tools to help policy makers and planners account for natural capital and ecosystem services in sectoral and macroeconomic policies have been explored and their application at the national and regional scale has been demonstrated. Several detailed case studies are presented in which the understanding of ecosystem services values has successfully informed decisions, including examples from Chile, South Africa, Tanzania, Trinidad and Tobago, Vietnam and the Aral Sea in Central Asia. These provide the critically important insights, lessons learned and means and mechanisms for policy makers to incentivize protection and discourage degradation of ecosystems and the services they provide. Mainstreaming Natural Capital and Ecosystem Services into Development Policy is designed to help decision makers at all levels, including governments, businesses, multilevel development banks and individuals to integrate ecosystems and their services into their decision making.

This book reviews up-to-date knowledge on the biology of sole (Solea senegalensis and S. solea). These flatfish species are increasingly important in Europe both from the ecological and production point of view. This book is divided into two sections: A. general fisheries, aquaculture and engineering overviews; B. physiological, developmental, rhythmic, welfare and genetic aspects which will be of immense interest for the aquaculture industry. Experts, from both academia and research institutes, provide their expertise on sole biology.

This book begins with a brief account of the extraordinary sequence of events that led to emergence of grasslands as major vegetation formations that now occupy some of the driest and hottest and the highest and coldest on earth as well as vast steppes and prairies in more temperate climes. It is the story of grasses successfully competing with forests and woodlands, aided and abetted by grazing herbivores and by humans and their use of fire as a tool. It is a story of adaptation to changing climates and the changing biophysical environments. A major focus of the book is the Palaearctic biogeographic realm that extends over some 45 million km(2) and thus more than 1/3 of the terrestrial ice-free surface on Earth. It comprises extensive grasslands of different types and origin, which can be subdivided into (1) natural grasslands with (1a) steppes (climatogenic in dry climates), (1b) arctic-alpine grasslands (climatogenic in cold climates) and (1c) azonal and extrazonal grasslands (pedogenic and topogenic) as well as (2) secondary grasslands created and sustained by human activities, such as livestock grazing, mowing or burning. Grasslands of the Palaearctic do not only form a major basis for the agriculture of the region and thus its food supply, but are also crucial for other ecosystem services and host a supra proportional part of the realm's plant and animal diversity. To reflect that suitability of grasslands for biodiversity strongly depends on their state, we apply the term High Nature Value grassland to those natural grasslands that are not degraded (in good state) and those secondary grasslands that are not intensified (semi-natural). The situation in a variety of countries where grasslands are evolving under the influence of global climate change is also considered. Case studies are presented on Southern Africa, Eastern Africa, India, China, South America, North America and Australia. The concluding chapter examines a set of themes arising from the chapters that make up the bulk of this book. The following provide a focus: recent history of grassland biomes - brief recap of current thinking and recent trends with special reference to dry grasslands in the Palearctic regions; the current status of grasslands and germplasm resources (biodiversity) - an overview; management systems that ensure sustainability; how to recover degraded grasslands; socio-economic issues and considerations in grassland management; the impacts of environmental problems in grasslands such as future climate change and intensification and the problems/prospects facing pastoralists and other grassland-based livestock producers.

Insects have evolved very unique and interesting tactics using chemical signals to survive. Chemical ecology illustrates the working of the biological network by means of chemical analyses. Recent advances in analytical technology have opened the way to a better understanding of the more complicated and abyssal interactions of insects with other organisms including plants and microbes. This book covers recent research on insects and chemical communications and presents the current status about challenges faced by chemical ecologists for the management of pests in agriculture and human health.

Mathematical Models of Plant-Herbivore Interactions addresses mathematical models in the study of practical questions in ecology, particularly factors that affect herbivory, including plant defense, herbivore natural enemies, and adaptive herbivory, as well as the effects of these on plant community dynamics. The result of extensive research on the use of mathematical modeling to investigate the effects of plant defenses on plant-herbivore dynamics, this book describes a toxin-determined functional response model (TDFRM) that helps explains field observations of these interactions. This book is intended for graduate students and researchers interested in mathematical biology and ecology.

In many places in the world, forests dominate landscapes and provide various products. Future climate change could profoundly alter the productivity of forest ecosystems and species composition. Until now, climate impact research has primarily focused on the likely impacts of rise in temperature, increased atmospheric CO2 concentration, and varying precipitation on unmanaged forests. The issue that now needs to be addressed is how to sustainably manage climate change for timber production and biomass. Though climate change is a global issue, impacts on forests depend on local environmental conditions and management methods, so this book will look at the issue under varying local contexts.

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.
