Plant Pathogenesis and Disease Control (Hardcover): Hachiro Oku Plant Pathogenesis and Disease Control (Hardcover)
Hachiro Oku
R5,765 Discovery Miles 57 650 Ships in 10 - 15 working days

Environmental pollution resulting from widespread pesticide application has become a serious worldwide problem. Plant Pathogenesis and Disease Control is an important new reference that addresses this problem by exploring the biochemical and molecular mechanisms of plant pathogenesis and emphasizing the use of "pest control agents" rather than "pesticides" for plant disease control. Topics examined include pathogenicity, the resistance of plants against pathogens, the offensive and defensive struggle between hosts and parasites, methods for using natural defense mechanisms to develop environmentally sound disease control agents, and the use of modern biotechnology for plant disease control. The book will be an essential reference for phytopathologists, plant biochemists, pesticide chemists, mycologists, plant cell technologists, and agricultural researchers.

Breeding Insect Resistant Crops for Sustainable Agriculture (Hardcover, 1st ed. 2017): Ramesh Arora, Surinder Sandhu Breeding Insect Resistant Crops for Sustainable Agriculture (Hardcover, 1st ed. 2017)

This book reviews and synthesizes the recent advances in exploiting host plant resistance to insects, highlighting the role of molecular techniques in breeding insect resistant crops. It also provides an overview of the fascinating field of insect-plant relationships, which is fundamental to the study of host-plant resistance to insects. Further, it discusses the conventional and molecular techniques utilized/useful in breeding for resistance to insect-pests including back-cross breeding, modified population improvement methods for insect resistance, marker-assisted backcrossing to expedite the breeding process, identification and validation of new insect-resistance genes and their potential for utilization, genomics, metabolomics, transgenesis and RNAi. Lastly, it analyzes the successes, limitations and prospects for the development of insect-resistant cultivars of rice, maize, sorghum and millet, cotton, rapeseed, legumes and fruit crops, and highlights strategies for management of insect biotypes that limit the success and durability of insect-resistant cultivators in the field. Arthropod pests act as major constraints in the agro-ecosystem. It has been estimated that arthropod pests may be destroying around one-fifth of the global agricultural production/potential production every year. Further, the losses are considerably higher in the developing tropics of Asia and Africa, which are already battling severe food shortage. Integrated pest management (IPM) has emerged as the dominant paradigm for minimizing damage by the insects and non-insect pests over the last 50 years. Pest resistant cultivars represent one of the most environmentally benign, economically viable and ecologically sustainable options for utilization in IPM programs. Hundreds of insect-resistant cultivars of rice, wheat, maize, sorghum, cotton, sugarcane and other crops have been developed worldwide and are extensively grown for increasing and/or stabilizing crop productivity. The annual economic value of arthropod resistance genes developed in global agriculture has been estimated to be greater than US$ 2 billion Despite the impressive achievements and even greater potential in minimizing pest- related losses, only a handful of books have been published on the topic of host-plant resistance to insects. This book fills this wide gap in the literature on breeding insect- resistant crops. It is aimed at plant breeders, entomologists, plant biotechnologists and IPM experts, as well as those working on sustainable agriculture and food security.

R4,349 Discovery Miles 43 490 Ships in 10 - 15 working days

Plants are frequently exposed to unfavorable and adverse environmental conditions known as abiotic stressors. These factors can include salinity, drought, heat, cold, flooding, heavy metals, and UV radiation which pose serious threats to the sustainability of crop yields. Since abiotic stresses are major constraints for crop production, finding the approaches to enhance stress tolerance is crucial to increase crop production and increase food security. This book discusses approaches to enhance abiotic stress tolerance in crop plants on a global scale. Plants scientists and breeders will learn how to further mitigate plant responses and develop new crop varieties for the changing climate.

The Aquatic Frontier - Oysters and Aquaculture in the Progressive Era (Paperback): Samuel P. Hanes The Aquatic Frontier - Oysters and Aquaculture in the Progressive Era (Paperback)
Samuel P. Hanes
R691 Discovery Miles 6 910 Ships in 7 - 11 working days

Although few remember their former significance, oysters were one of the largest U.S. fisheries at their peak in the late nineteenth century. As the fishery industrialized on-and offshore, oyster farms and canning factories spread along the Eastern Seaboard, with overharvesting becoming increasingly common. During the Progressive Era, state governments founded new agencies to cope with this problem and control this expanding economy. Regulators faced a choice: keep elaborate conservation systems based on common property rights or develop new ones with private, hatchery-stocked aquaculture farms. The tradition-preserving solution won, laying the groundwork for modern oyster management. The Aquatic Frontier explores the forms this debate took between 1870 and 1920 in law enforcement, legislative advising, natural science, and oyster cartography. Samuel P. Hanes argues that the effort to centralize and privatize the industry failed due to a lack of understanding of the complex social-ecological systems in place - a common dilemma for environmental managers in this time period and for fisheries management confronting dangers from dwindling populations today.

Stephen Spotte, Mote Marine Laboratory, Sarasota, Florida, USA Tarpons arose from an ancient lineage, and just two species exist today, confined to the tropics and subtropics: Megalops atlanticus in the western and eastern Atlantic and Megalops cyprinoides distributed widely across the Indo-West Pacific. The Atlantic tarpon is considered king of the saltwater sport fishes and supports a multi-billion dollar recreational fishery in the U.S. alone. The Pacific tarpon, which is much smaller, is less valued by anglers. Both have limited commercial value but offer considerable potential for future aquaculture because of their hardiness, rapid growth, and ease of adaptation to captivity. This book is the latest and most thorough text on the biology, ecology, and fisheries (sport and commercial) of tarpons. The chapters comprise clear, intricate discourses on such subjects as early development and metamorphosis, population genetics, anatomical and physiological features and adaptations, migrations, reproductive biology, and culminate with a concise overview of the world's tarpon fisheries. A comprehensive appendix includes Spotte's original translations of important papers published previously by others in Spanish and Portuguese and unavailable until now to English readers. Tarpons: Biology, Ecology, Fisheries will be of considerable interest and use to fishery and research biologists, marine conservationists, aquaculturists, and informed anglers

R2,270 Discovery Miles 22 700 Ships in 10 - 15 working days

Agriculture as a social-ecological system embraces many disciplines. This book breaks through the silos of individual disciplines to bring ecologists and economists together to consider agriculture through the lens of resilience. It explores the economic, environmental and social uncertainties that influence the behaviour of agricultural producers and their subsequent farming approach, highlighting the importance of adaptability, innovation and capital reserves in enabling agriculture to persist under climate change and market volatility. The resilience concept and its relation to complexity theory is explained and the characteristics that foster resilience in agricultural systems, including the role of biodiversity and ecosystem services, are explored. The book discusses modelling tools, metrics and approaches for assessing agricultural resilience, highlighting areas where interdisciplinary thinking can enhance the development of resilience. It is suitable for those researching sustainable agriculture or those engaged in agricultural policy decisions and analysis, as well as students of ecology, agriculture and socioeconomics.

R1,813 Discovery Miles 18 130 Ships in 10 - 15 working days

In this work, several modelling approaches are explored to represent spatial pattern dynamics of aquatic populations in aquatic ecosystems by the combination of models, knowledge and data in different scales.

It is shown that including spatially distributed inputs retrieved from Remote Sensing images, a conventional physically-based Harmful Algal Bloom model can be enhanced. Also, Cellular Automata based models using high resolution photographs prove to be good in representing aquatic plant growth. Multi-Agent Systems can capture well the spatial patterns exhibited in GIS density maps. A synthesis modelling framework was developed to include biological/ecological growth and diffusive processes, and local effects in conventional modelling framework. The results of the complementary modelling paradigms investigated in this research can be of help in achieving a sustainable environmental management strategy.

2018 Nebraska Book Award 2018 Outstanding Academic Title, selected by Choice Homesteading the Plains offers a bold new look at the history of homesteading, overturning what for decades has been the orthodox scholarly view. The authors begin by noting the striking disparity between the public's perception of homesteading as a cherished part of our national narrative and most scholars' harshly negative and dismissive treatment. Homesteading the Plains reexamines old data and draws from newly available digitized records to reassess the current interpretation's four principal tenets: homesteading was a minor factor in farm formation, with most Western farmers purchasing their land; most homesteaders failed to prove up their claims; the homesteading process was rife with corruption and fraud; and homesteading caused Indian land dispossession. Using data instead of anecdotes and focusing mainly on the nineteenth century, Homesteading the Plains demonstrates that the first three tenets are wrong and the fourth only partially true. In short, the public's perception of homesteading is perhaps more accurate than the one scholars have constructed. Homesteading the Plains provides the basis for an understanding of homesteading that is startlingly different from current scholarly orthodoxy. Purchase the audio edition.

The main objective of this book is to integrate environmental knowledge observed in local agriculture, based on the understanding of soils science and ecology, and to propose possible technical solutions and a more integrated approach to tropical agriculture. The chapters describe and analyze the ecological and technical countermeasures available for mitigating environmental degradation due to the increasing agricultural activities by humans, based on our scientific understanding of traditional agriculture in the tropics. This is an effective approach, as such ecological and technical tools previously involved in traditional activities are expected to be easily incorporated into present agricultural systems. The book starts with a rather classical pedological issue and analyzed traditional agricultural practices with different resource management strategies in terms of their modification of natural biological processes. It focuses on the present situation of tropical agriculture; that is, resource utilization in modern agriculture after application of technical innovation (increased application of chemical fertilizers as well as agricultural chemicals). Here, possible technical approaches to resource management that reasonably support agricultural production whilst mitigating environmental degradation are discussed. The negative impacts of agricultural development on our environment are rapidly growing, yet we are increasingly dependent on the agricultural sector for food and energy. The situation is similar in the tropics, where subsistence agriculture with low input management has long comprised most agricultural systems. Comparison of ecological and/or agronomical studies between different continents are still rare; therefore, this analysis may help clarify what is an essential problem when considering technical transportation beyond continents and/or between temperate and tropical regions.
