Biology and Ecology of Fishes Immerse yourself in the world of fish ecology with the newest edition of this essential introduction The study of fish ecology has traditionally proceeded along two tracks: the first is more basic, concerned with the anatomy, physiology and theoretical ecology of fish, and the second is more practical, concerning itself with fish populations, management, and habitats. Many fish researchers have come to view this distinction as artificial, and to develop a new study of fish that combines both tracks in a single holistic approach. It has never been more critical for introductory textbooks to represent this combined study in order to prepare the next generation of fish biologists and fishery scientists. Biology and Ecology of Fishes meets this need with a textbook that incorporates both biology and population management. Beginning with a general introduction to aquatic life and ecosystems, this book covers anatomical, environmental, and ethological topics to give a thoroughly rounded view of its subject, promising to serve as the fundamental introduction to multidisciplinary fish studies. Readers of the third edition of Biology and Ecology of Fishes will also find: Detailed coverage of subjects including growth and bioenergetics, feeding and predation, mortality and recruitment and more Increased attention to stressors of fish populations and communities New and revised chapters that introduce quantitative methods and present emerging issues facing fish populations and communities Biology and Ecology of Fishes is a useful overview for advanced undergraduate and graduate students studying fish ecology or fishery biology, as well as a reference for researchers and professionals in fish ecology, fish population management, and related fields.

Maize has been described as a primary catalyst to complex sociocultural development in the Americas. State of the art research on maize chronology, molecular biology, and stable carbon isotope research on ancient human diets have provided additional lines of evidence on the changing role of maize through time and space and its spread throughout the Americas. The multidisciplinary evidence from the social and biological sciences presented in this volume have generated a much more complex picture of the economic, political, and religious significance of maize. The volume also includes ethnographic research on the uses and roles of maize in indigenous cultures and a linguistic section that includes chapters on indigenous folk taxonomies and the role and meaning of maize to the development of civilization. Histories of Maize is the most comprehensive reference source on the botanical, genetic, archaeological, and anthropological aspects of ancient maize published to date. This book will appeal to a varied audience, and have no titles competiting with it because of its breadth and scope. The volume offers a single source of high quality summary information unavailable elsewhere.

Since the advent of agriculture approximately 12,000 years ago, human activity has created a unique set of ecosystems. However, the recent development of world markets, rapid technological advances, and other changes to farming practices have led to hugely increased pressures on farm habitats and organisms. Global human populations are rising and diets are becoming ever more complicated, leading to unrelenting requirements for increased levels of food production. Natural biotopes are becoming increasingly fragmented as agricultural activities expand around them. "Agroecosystems" now occur from the tropics to subarctic environments and comprise systems as varied as annual crops, perennial grasslands, orchards, and agroforestry systems. They presently cover almost 40% of the terrestrial land surface and significantly shape landscapes at a global scale. This key addition to the OUP Biology of Habitats Series provides a novel perspective on agroecosystems, summarising our current understanding of the basic and applied aspects of these important and complex habitats, whilst focusing on environmental concerns in the context of global change. The Biology of Agroecosystemsis is for both senior undergraduate and graduate students taking courses in agroecology, farmland ecology, conservation, and agriculture as well as the many professional ecologists, conservation biologists, and land managers requiring a concise overview of agroecology.

This book meets the needs of teachers and students of agriculture and rural development project and programme planning, planners employed by governments in developing countries and by external financing agencies. Project planners must understand the aspirations of rural families and their local leaders, the national development and sector planning goals and policies of their governments and the development goals and policy priorities perceived by external financing agencies in relation to their countries. These areas are not always consistent and trade-offs may be required. However it is recognised that poor project planning is a major constraint to the sustainable realization of project and programme objectives and sector goals. Illustrated with case studies and logical framework matrices, this book presents well-established and relatively new practices followed in the context of agriculture and rural development project and programme planning. Although based on experiences gained in Africa, the issues described are relevant to planning problems encountered in other developing regions of the world. It addresses the main factors which affect the success of planning such as a government's ability to guarantee macro-economic stability and sound sector development policies; the shift from 'top-down', bureaucratic to 'bottom-up', participatory planning approaches and the roles played by external financing agencies. It explains key technical, financial, economic, environmental, socio-cultural, equity, gender and institutional-strengthening issues concerning planning in rural areas and reviews the planning tools and approaches available. The procurement of goods and services, the disbursement of funds and monitoring and evaluation requirements are examined in detail.

This book is an interdisciplinary primer on critical thinking and effective action for the future of our global agrifood system, based on an understanding of the system's biological and sociocultural roots. Key components of the book are a thorough analysis of the assumptions underlying different perspectives on problems related to food and agriculture around the world and a discussion of alternative solutions. David Cleveland argues that combining selected aspects of small-scale traditional agriculture with modern scientific agriculture can help balance our biological need for food with its environmental impact--and continue to fulfill cultural, social, and psychological needs related to food. Balancing on a Planet is based on Cleveland's research and engaging teaching about food and agriculture for more than three decades. It is a tool to help students, faculty, researchers, and interested readers understand debates about the current crisis and alternatives for the future.

“Zhun Xu’s careful analysis debunks the conventional wisdom about the supposed failure of agricultural collectives in China. Xu’s reassessment of the path of agrarian change in China since 1949, which relies on interviews with peasants as well as statistical analysis, provides a fascinating window into the successes and the problems of collective farming in China.�—David M. Kotz, Professor of Economics, University of Massachusetts Amherst; author, The Rise and Fall of Neoliberal Capitalism In the early 1980s, China undertook a massive reform that dismantled its socialist rural collectives and divided the land among millions of small peasant families. Known as the decollectivization campaign, it is one of the most significant reforms in China's transition to a market economy. From the beginning, the official Chinese accounts, and many academic writings, uncritically portray this campaign as a huge success, both for the peasants and the economy as a whole. This mainstream history argues that the rural communes, suffering from inefficiency, greatly improved agricultural productivity under the decollectivization reform. It also describes how the peasants, due to their dissatisfaction with the rural regime, spontaneously organized and collectively dismantled the collective system. A closer examination suggests a much different and more nuanced story. By combining historical archives, field work, and critical statistical examinations, From Commune to Capitalism argues that the decollectivization campaign was neither a bottom-up, spontaneous peasant movement, nor necessarily efficiency-improving. On the contrary, the reform was mainly a top-down, coercive campaign, and most of the efficiency gains came from simply increasing the usage of inputs, such as land and labor, rather than institutional changes. The book also asks an important question: Why did most of the peasants peacefully accept this reform? Zhun Xu answers that the problems of the communes contributed to the passiveness of the peasantry; that decollectivization, by depoliticizing the peasantry and freeing massive rural labor to compete with the urban workers, served as both the political and economic basis for consequent Chinese neoliberal reforms and a massive increase in all forms of economic, political, and social inequality. Decollectivization was, indeed, a huge success, although far from the sort suggested by mainstream accounts.

Throughout the tropical world, especially in South and Southeast Asia, tropical America, Africa and Oceania, there exists a range of forest garden farming systems. These are small, low-input, but productive and sustainable family units of highly diversified trees, palms, bushes and vines, with few conventional field crops or livestock. Providing a survey of these systems around the world and an in-depth analysis of the farms around Kandy, Sri Lanka, this book offers an economic and ecological description and evaluation of this ancient agroforestry system and its relationship to a wide range of global agro-development and environmental problems. Guided by a table that lists some 30 socio-economic and social criteria by which all farming systems can and should be evaluated, the book presents persuasive evidence supported by comprehensive references. It also examines historical and archaeological findings in order to assess the role these tropical forests played in the general adoption of agricultural farming.

Today the use of the term countryside reflects a dual historical shift due to the decreasing importance of agriculture - both in terms of employment and production - in European economies and the shift toward the environment. An increasing part of rural populations is being drawn into non-agricultural sectors such as tourism, construction, manufacturing, and the conventional and innovative services, thereby granting a more diversified and contemporary role to the countryside. The environmental shift has questioned many of the very fundamental premises governing the relationship between social practices and nature. Agenda 2000 and the ongoing debate concerning the CAP reforms are connected to a large extent with these new realities. This engaging book focuses on the prospects for the development of the Southern European countryside during a transitional period of a major policy paradigm shift. Bringing together case studies from Portugal, Spain, France, Italy and Greece, the book discusses the key issues mentioned above, as well as the restricting factors and prospects of the adjustments required.

This book aims at providing students, experts and practitioners with a detailed overview of agricultural and food security issues in China, analyzed through the lenses of a multidisciplinary approach that enables to fully grasp the current socio-political challenges and lock-ins of agricultural transformation towards more sustainable practices. Confronted to a running decrease and degradation of its resources and rapidly evolving food habits, China became a net importer of food in 2004, and its agricultural balance has since become heavier every day. Beyond providing a comprehensive overview of these stakes, this book also presents consistent and original first hand research material, collected by the author during months of fieldwork in China, in the countryside and from various economic and political circles. Conclusions drawn from this often difficult to access) fieldwork shed light on the whole galaxy of public and private stakeholders taking part in agricultural modernization in China, on their interests and on the patterns of power that underlie the development and implementation of agricultural policies.

An eye-opening guide to how America feeds itself and an essential companion book to the new documentary.

America’s food system is broken, harming family farmers, workers, the environment, and our health. But it doesn’t have to be this way. Here, brilliant innovators, scientists, journalists and activists explain how we can create a hopeful new future for food, if we have the courage to seize the moment.

In 2008, the award-winning documentary Food, Inc. shook up our perceptions of what we ate. Now, the movie’s timely sequel and this new companion book will address the remarkable developments in the world of food—from lab-grown meat to the burgeoning food sovereignty movement—that have unfolded since then.

This book is the perfect roadmap to understanding not only our current dysfunctional food system, but also what each of us can do to help reform it.

The book is an interdisciplinary synthesis of research and practice carried out over decades by leaders of the agroecology and regenerative organic agriculture movement. It provides detailed analysis of the multiple crises we face due to chemical and industrial agriculture, including land degradation, water depletion, biodiversity erosion, climate change, agrarian crises, and health crises. The book lays out biodiversity based organic farming and agroecology as the road map for the future of agriculture and sustainable food systems, both locally and globally. With detailed scientific evidence, Agroecology & Regenerative Agriculture shows how ecological agriculture based on working with nature rather than abasing ecological laws can regenerate the planet, the rural economy, and our health.

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.

Successful management of agricultural landscapes depends on the recognition of the relationships between the processes and the structures that maintain the system. The rapidly growing science of Landscape Ecology quantifies the ways these ecosystems interact and establishes a link between the activities in one region and repercussions in another. Although science continuously yields new environmentally friendly agricultural technology, the sustainable development of a system will ultimately depend on a farmer's ability to understand and utilize these advances. The results presented in this book highlight the options for controlling threats and present guidelines for the implementation of environmentally friendly landscape management.

Written by eminent scientists in landscape ecology research, Landscape Ecology in Agroecosystems Management provides a systematic evaluation of the basic ecological functions of the agricultural landscape. It presents a new approach to managing heat balance parameters and evaluates the effectiveness of models for assessing land use changes in rural areas. It also discusses the methods of evaluating matter cycling in agricultural landscapes with emphasis on the process leading to the diffuse pollution problems in ground and surface waters. It reports studies that show how semi-natural habitats maintained in the agricultural landscape constitute important refuge for many plants and animals and thereby enhances biological diversity in farmlands. Finally, it provides guidelines for management of agricultural landscapes for sustainable development of the countryside.

The integration of agriculture and the natural ecosystem in the landscape has recently become a "hot" topic. The review of the achievements in landscape ecology presented in this book clearly demonstrates that landscape ecology is just passing through the threshold between the recognition of various basic processes to being able to manage these processes to achieve desired goals. This transformation will result not only from the development of knowledge, but also by the change in nature protection paradigms. Whether you are researching, designing, or managing agroecosystems, Landscape Ecology in Agroecosystems Management is a "must have" book.
