The Ruff is a fascinating species whose elaborate breeding behaviour has captivated ornithologists for decades. Their communal display grounds, or leks, provide an extreme example of a social system widespread in birds and other animals, in which brilliantly plumaged males seemingly compete for the attention of passing females. In this book, Johan van Rhijn explores this complex and intricate drama, both to lay bare the details of the players' private lives, and to provide a means of exploring the wider variety of wader breeding systems. Strands of evidence for all aspects of the Ruffs life, in and out of the breeding season, come together to give a thought-provoking insight into this important area of biology. Specialists and birdwatchers alike will have much to learn from this intriguing story and the insights it provides. Illustrated by Ian Willis.

The complete resource on performing sustainable renovations for both Historic and modern existing buildings This forward-looking and insightful guide explores how the sustainable renovation of existing buildings presents great opportunities for initiating extensive changes in the performance of the built environment. Great examples of existing building upgrades are examined, illustrating how to do sustainable renovations, along with current design approaches for radically improving the functionality of existing prewar, postwar, and late modern buildings. Sustainable Renovation saves its key focus for institutional and commercial buildings, but discusses the challenges they pose within a global scope that encompasses all building practices. Some of the discussions in this book include: The significance of energy and resource demands by the building sector and the urgency of reducing loads in existing buildings Management, design, and construction approaches to achieve major modernization in occupied buildings International case studies that focus on methods and benefits of successful sustainable transformations of existing building performance Repurposing buildings to preserve style and add performance remains a work in progress as designers and builders discover new methods for improving sustainable practices and standards. With incremental modernization and operations strategies available for immediate implementation, this book demonstrates the different ways of thinking necessary when considering and attempting the integration of sustainable concepts into existing buildings—and enables readers to rethink the world that's built around them.

Migration, broadly defined as directional movement to take advantage of spatially distributed resources, is a dramatic behaviour and an important component of many life histories that can contribute to the fundamental structuring of ecosystems. In recent years, our understanding of migration has advanced radically with respect to both new data and conceptual understanding. It is now almost twenty years since publication of the first edition, and an authoritative and up-to-date sequel that provides a taxonomically comprehensive overview of the latest research is therefore timely. The emphasis throughout this advanced textbook is on the definition and description of migratory behaviour, its ecological outcomes for individuals, populations, and communities, and how these outcomes lead to natural selection acting on the behaviour to cause its evolution. It takes a truly integrative approach, showing how comparisons across a diversity of organisms and biological disciplines can illuminate migratory life cycles, their evolution, and the relation of migration to other movements. Migration: The Biology of Life on the Move focuses on migration as a behavioural phenomenon with important ecological consequences for organisms as diverse as aphids, butterflies, birds and whales. It is suitable for senior undergraduate and graduate level students taking courses in behaviour, spatial ecology, 'movement ecology', and conservation. It will also be of interest and use to a broader audience of professional ecologists and behaviourists seeking an authoritative overview of this rapidly expanding field.

Norman Keeler is a young man exiled from his home by the necessities of World War 1. He then is unjustly accused of a heinous crime, shot by the police, jailed, then finally exonerated he flees, assumes an alias, and lives in the United States as a cowboy. He marries and adopts a son. He is betrayed by his wife and left with the boy to raise. He wanders throughout the depression years and takes another woman, though he cannot marry her. They have a child, a daughter, and move into a cabin on the Fraser River north of Prince George, B.C. They live by hunting, foraging, growing a garden, and what little money he can earn working odd jobs down the valley or prospecting for gold in the river. Their daughter tells the rest of the story of hardship, danger and survival as another child is born to them, a son. They are so far from roads and transportation that they must carry their supplies on their backs or on dogsleds. They fight the intense cold, deep snow, flooding rivers and wild animals as long as his strength lasts.
