Crozier – författare

This book is about the genetics and behaviour of individuals within colonies of social insects - bees, wasps, ants, and termites. Colonial living is characterized by division of labour and finely coordinated organization, by reproductive function being limited to certain individuals, by cooperative brood care, and by the presence of non-reproductive workers. Within a colony, however, many events are the result of conflicts between individuals seeking to maximize their own interests. Ever since Darwin, this interplay of cooperation and conflict has raised many important questions in evolutionary biology, especially about how cooperative behaviour is maintained in the absence of direct reproduction by workers. How is the heritable component of this behaviour passed on? Crozier and Pamilo's contribution is to analyse the genetic basis of the patterns of reproduction and resource allocation found in social insect colonies. This is done more comprehensively and with greater depth and insight than in any previous study, and is a significant step forward in the fields of population genetics and social evolution.

With the increasing need to take an holistic view of landslide hazard and risk, this book overviews the concept of risk research and addresses the sociological and psychological issues resulting from landslides. Its integrated approach offers understanding and ability for concerned organisations, landowners, land managers, insurance companies and researchers to develop risk management solutions. Global case studies illustrate a variety of integrated approaches, and a concluding section provides specifications and contexts for the next generation of process models.

Essentials of Social Anxiety is a shorter, revised paperback edition of The International Handbook of Social Anxiety, focusing on developmental and clinical perspectives. It is organized into two parts: The Development of Social Anxiety; and Clinical Perspectives and Interventions. Like the International Handbook, it covers research, assessment and treatment, giving clinical practitioners comprehensive coverage of the area and a single concise desk reference.

This Handbook offers comprehensive coverage of current knowledge and recent advances with major sections on the origin and development of shyness and social anxiety, on social and personality factors, and on clinical perspectives and interventions. The editors have drawn together some of the worlds leading international experts from diverse disciplines offering a critical focus on knowledge that is research-based, central to the understanding of social anxiety, and of essential interest to a wide range of students, researchers and professionals. ? A state-of-the-art account of knowledge in this field ? Contributions by leading academics, researchers, and clinicians ? Comprehensive coverage of the field representing different theoretical and clinical approaches ? Focused on key research and critical concepts

Plant secondary metabolites have been a fertile area of chemical investigation for many years, driving the development of both analytical chemistry and of new synthetic reactions and methodologies. The subject is multi-disciplinary with chemists, biochemists and plant scientists all contributing to our current understanding. In recent years there has been an upsurge in interest from other disciplines, related to the realisation that secondary metabolites are dietary components that may have a considerable impact on human health, and to the development of gene technology that permits modulation of the contents of desirable and undesirable components. Plant Secondary Metabolites: Occurrence, Structure and Role in the Human Diet addresses this wider interest by covering the main groups of natural products from a chemical and biosynthetic perspective with illustrations of how genetic engineering can be applied to manipulate levels of secondary metabolites of economic value as well as those of potential importance in diet and health. These descriptive chapters are augmented by chapters showing where these products are found in the diet, how they are metabolised and reviewing the evidence for their beneficial bioactivity.
