Molecular Plant Immunity provides an integrated look at both well-established and emerging concepts in plant disease resistance providing the most current information on this important vitally important topic within plant biology. Understanding the molecular basis of the plant immune system has implications on the development of new varieties of sustainable crops, understanding the challenges plant life will face in changing environments, as well as providing a window into immune function that could have translational appeal to human medicine. Molecular Plant Immunity opens with chapters reviewing how the first line of plant immune response is activated followed by chapters looking at the molecular mechanisms that allow fungi, bacteria, and oomycetes to circumvent those defenses. Plant resistance proteins, which provide the second line of plant immune defense, are then covered followed by chapters on the role of hormones in immunity and the mechanisms that modulate specific interaction between plants and viruses. The final chapters look at model plant-pathogen systems to review interaction between plants and fungal, bacterial, and viral pathogens. Written by a leading team of international experts, Molecular Plant Immunity will provide a needed resource to diverse research community investigated plant immunity.

Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

Weeds are variously defined as plants growing where they are not wanted, plants that interfere with human activity. Weeds affect everyone in the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding, reducing animal health, preventing water flow, as plant parasites, etc. It is estimated that those problems cause $ billions worth of crop losses annually and the global cost of controlling weeds also runs into many $ billions every year. Atlas of Weed Mapping presents an introductory overview on the occurrence of the most common weeds of the world. The book notably includes: Description of cropping practices and explanations for the global distribution of weeds Invasive plant mapping Aquatics and wetland plants with histological plant details Theoretical and practical aspects of weed mapping Aspects on the documentation of herbicide resistance Biodiversity, rare weeds and the dominance of the most common weeds Fully illustrated with more than 800 coloured figures and a number of tables, this new characterisation of anthropogenic vegetation will be interesting for readers of a great number of disciplines such as agriculture, botany, ecology, geobotany and plant community research. More than a hundred experts have contributed data to this unique compilation.

A functional discussion of the crop selection process for biomass energy The Selection Process of Biomass Materials for the Production of Bio-fuels and Co-firing provides a detailed examination and analysis for a number of energy crops and their use as a source for generating electricity and for the production of bio-fuels. Renowned renewable energy expert and consultant Dr. Najib Altawell begins with the fundamentals of bio-fuels and co-firing and moves on to the main feature, which is the methodology that assists energy scientists and engineers to arrive at the most suitable biomass materials tailored to each company’s business and economic environments and objectives. This methodology provides a framework whereby power-generating companies can insert their own values for each factor, whether business factor (BF) or scientific & technical factors (S&T) or both simultaneously. The methodology provides a list of factors related to the biomass energy business. The average values have been obtained from the survey method and laboratory tests. These values are the standard values power companies can use if they need or wish to use them. The Selection Process of Biomass Materials for the Production of Bio-fuels and Co-firing has been designed and compiled for the widest possible range of readers, researchers, businesspeople, and economists who are connected to the renewable energy field in general, and biomass energy in particular. Because of its focus on practical data and applications, the book is also accessible for general readers who may or may not have a technical or scientific background.

Meat has been a long sought after source of nutrients in human diets. Its nutrient-dense composition of protein, fats, vitamins and minerals makes it an integral part to healthy and balanced diets. As demand for meat continues to increase globally, a better understanding of efficiently producing quality meat products is becoming increasingly important. The Science of Meat Quality provides comprehensive coverage of meat quality from the biological basis of muscle development to end-product-use topics such as preparation and sensory analysis. The Science of Meat Quality explores the basis of meat quality long before it hits grocery store shelves. The book opens with a look at cellular muscle tissue development, metabolism and physiology. Subsequent chapters look at topics surrounding the development of tenderness, water-holding capacity, lipid oxidation and color in meat products. The final chapters discuss producing a good-tasting end product from preparing meat to preventing food-borne illness. Each chapter contains not only the theory behind that topic, but also detailed lab methodologies for measuring each meat quality trait. The Science of Meat Quality is an essential resource and reference for animal scientists, meat scientists, food scientists, and food industry personnel.

Plants interact with a wide variety of organisms in their natural growing environments. Key amongst these relationships is the interplay between plants and diverse fungal species that impact plants in complex symbiotic, parasitic and pathogenic ways. Biocomplexity of Plant-Fungal Interactions explores a broad spectrum of research looking at both positive and negative interactions of these relationships on plants and their ecosystems. Biocomplexity of Plant-Fungal Interactions takes a more holistic view of the plant-fungal interactions than most traditional volumes on the topic. Focusing on the truly complex biological interplay among plants and fungi, as well as other organisms—mammals, insects, bacteria, viruses, this book provides a unique perspective on this fundamentally important relationship. Chapters are written from molecular, evolutionary and ecological perspectives to provide readers with a full understanding of the diverse implications of plant-fungal interactions. Written by a global team of experts from varied scientific backgrounds, Biocomplexity of Plant-Fungal Interactions will be an essential title for readers looking for a better understanding of the diverse array of interactions between plants and fungi in natural ecosystems.

The Royal Entomological Society (RES) and Wiley-Blackwell are proud to present this landmark publication, celebrating the wonderful diversity of the insects of the British Isles, and the work of the RES (founded 1833). This book is the only modern systematic account of all 558 families of British insects, covering not just the large and familiar groups that are included in popular books, but even the smallest and least known. It is beautifully illustrated throughout in full colour with photographs by experienced wildlife photographers to show the range of diversity, both morphological and behavioural, among the 24,000 species. All of the 6,000 genera of British insects are listed and indexed, along with all the family names and higher groups. There is a summary of the classification, biology and economic importance of each family together with further references for detailed identification. All species currently subject to legal protection in the United Kingdom are also listed. The Royal Entomological Society is one of the oldest and most prestigious of its kind in the world. It is the leading organisation for professional entomologists and its main aim has always been the promotion of knowledge about insects. The RES began its famous Handbooks for the Identification of British Insects in 1949, and new works in that series continue to be published. The Royal Entomological Society Book of British Insects has been produced to demonstrate the on-going commitment of the RES to educate and encourage each generation to study these fascinating creatures. This is a key reference work for serious students of entomology and amateur entomologists, as well as for professionals who need a comprehensive source of information about the insect groups of the British Isles they may be less familiar with.

A decade ago no one except geologists had heard of tantalum or 'coltan' – an obscure mineral that is an essential ingredient in mobile phones and laptops. Then, in 2000, reports began to leak out of Congo: of mines deep in the jungle where coltan was extracted in brutal conditions watched over by warlords. The United Nations sent a team to investigate, and its exposé of the relationship between violence and the exploitation of coltan and other natural resources contributed to a re-examination of scholarship on the motivations and strategies of armed groups. The politics of coltan encompass rebel militias, transnational corporations, determined activists, Hollywood celebrities, the rise of China, and the latest iGadget. Drawing on Congolese and activist voices, Nest analyses the two issues that define coltan politics: the relationship between coltan and violence in the Congo, and contestation between activists and corporations to reshape the global tantalum supply chain. The way production and trade of coltan is organised creates opportunities for armed groups, but the Congo wars are not solely, or even primarily, about coltan or minerals generally. Nest argues the political significance of coltan lies not in its causal link to violence, but in activists' skillful use of mobile phones as a symbol of how ordinary people and transnational corporations far from Africa are implicated in Congo's coltan industry and therefore its conflict. Nest examines the challenges coltan initiatives face in an activist 'marketplace' crowded with competing justice issues, and identifies lessons from coltan initiatives for the geopolitics of global resources more generally.
