Wood ants play an ecologically dominant and conspicuous role in temperate boreal forests, making a keystone contribution to woodland ecosystem functions and processes. Wood ant taxonomy and global distributions set the scene for this text's exploration of wood ants as social insects, examining their flexible social structures, genetics, population ecology, and behaviour, from nest-mate recognition to task allocation. Wood ants' interactions with their environment and with other organisms are essential to their success: competition, predation and mutualism are described and analysed. Bringing together the expertise of ecological researchers and conservation practitioners, this book provides practical and theoretical advice about sampling and monitoring these insects, and outlines the requirements for effective conservation. This is an indispensable resource for wood ant researchers, entomologists, conservationists and ecological consultants, as well as anyone interested in social insects, keystone species and the management and conservation of forest ecosystems.

2004 marks the 100th anniversary of the first description of the autoimmune disease paroxysmal cold hemoglobinuria, a rare hemolytic disorder, by Julius Donath and Karl Landsteiner. After a century of research, the list of autoimmune diseases has become impressive. With a prevalence of approximately 5% of the world-wide population, these chronic, debilitating conditions affect almost every major organ of the body and, for reasons that remain unclear, are much more prevalent in woman than in men. Despite our rapidly expanding knowledge of the cellular and molecular pathways that govern a normal immune response, deciphering the precise etiology of autoimmune diseases remains an important challenge. Over the last few years, our understanding of the pathogenesis of autoimmune diseases has improved rapidly, leading to the emergence of elegant immunointervention strategies. Molecular Autoimmunity illustrates how cutting-edge research is continuing to advance our understanding of autoimmune disease mechanisms and identifies novel therapeutic targets that provide a hope for effective future treatments. This volume contains a selected number of exciting advances in unraveling autoimmune reactions, and the resulting new armory of experimental immunotherapies that may lead to new ways of controlling autoimmune reactions.

Few other fields in human biology have experienced such a tremendous progress as celiac disease has during the past few years. The contributors to 'Frontiers in Celiac Disease' are world-renowned opinion leaders who made these advances possible. Their expertise has been assembled here to provide a comprehensive overview of the current knowledge of the epidemiology, pathogenesis, clinical presentations, diagnosis and treatment of celiac disease. In addition, the stage is set for innovative strategies for preventive interventions and treatment alternatives to a gluten-free diet. A valuable reference for basic and translational scientists, this book also serves as a practical resource to healthcare professionals, including general practitioners, subspecialists, dieticians, nutritionists, and nurses and nurse practitioners. Students from different disciplines will find this book a helpful guide to expand and deepen their knowledge of celiac disease.

Conceptual models are a vital tool for understanding the processes that maintain the global ocean circulation, both in nature and in complex numerical ocean models. In this chapter we provide a broad overview of our conceptual understanding of the wind-driven circulation, the thermohaline circulation, and their transient behavior. While our conceptual understanding of the time-mean wind-driven circulation is now fairly mature, basic questions remain regarding the thermohaline circulation, for example, surrounding its overall strength and stability. Similarly, basic questions remain regarding the transient adjustment and internal variability of the ocean circulation.

The use of forensic entomology has become established as a global science. Recent efforts in the field bridge multiple disciplines including, but not limited to, microbiology, chemistry, genetics, and systematics as well as ecology and evolution. The first book of its kind, Forensic Entomology: International Dimensions and Frontiers provides an inc

The common bean (Phaseolus vulgaris L. ) is the most important pulse crop in the world. It is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. It complements cereals and other carbohydrate-rich foods in providing near-perfect nutrition to people of all ages. Moreover, a regular intake ofbeans helps lower cholesterol and cancer risks. Despite the fact that per capita consumption of common bean in some developed countries (e. g. , the U. S. A. ) has been increasing over the last several years, in general, the average global per capita consumption is declining because production is unable to keep up with the population growth. Moreover, increasing demand for pesticide-free food products, concern for natural resources conservation, and the need to reduce production costs offer daunting challenges to the twenty-first century policy makers, bean growers, and researchers alike. High yielding, high quality bean cultivars that require less water, fertilizers, pesticides, and manual labor combined with integrated management of abiotic and biotic stresses will have to be developed. Eminent bean researchers were invited to contemplate these issues, prepare a state-of-the-art account on most relevant topics, and offer their insight into research directions into the twenty-first century. Four excellent books have been published covering various aspects ofthe common bean since 1980. These books are: I) Bean Production Problems nd in the Tropics (l SI ed. 1980, 2 ed. 1989), H. F. Schwartz & M. A.

Forensic Entomology deals with the use of insects and other arthropods in medico legal investigations. We are sure that many people know this or a similar definition, maybe even already read a scientific or popular book dealing with this topic. So, do we really need another book on Forensic Entomology? The answer is 13, 29, 31, 38, and 61. These are not some golden bingo numbers, but an excerpt of the increasing amount of annual publications in the current decade dealing with Forensic Entomology. Comparing them with 89 articles which were published d- ing the 1990s it illustrates the growing interest in this very special intersection of Forensic Science and Entomology and clearly underlines the statement: Yes, we need this book because Forensic Entomology is on the move with so many new things happening every year. One of the most attractive features of Forensic Entomology is that it is multid- ciplinary. There is almost no branch in natural science which cannot find its field of activity here. The chapters included in this book highlight this variety of researches and would like to give the impetus for future work, improving the dev- opment of Forensic Entomology, which is clearly needed by the scientific com- nity. On its way to the courtrooms of the world this discipline needs a sound and serious scientific background to receive the acceptance it deserves.

The first section reviews trends of bean production and constraints in Latin America and Africa. The second section covers fungal diseases. The third section, bacterial diseases. The fourth section, viral and mycoplasma diseases. The fifth section, insect pests. The last section, other bean production constraints, that is, nutritional disorders, nematodes, seed pathology, and additional problems.

An epitope is a structural region of an antigen that is recognized by an antibody and is therefore central to the immune response. Epitope Mapping describes the various methods for their location and characterization. This process is an essential part of developing non-pathogenic vaccines.
