Big Questions in Ecology and Evolution
This book provides an introduction to a range of fundamental questions that have taxed evolutionary biologists and ecologists for decades. All of the questions posed have at least a partial solution, all have seen exciting breakthroughs in recent years, yet many of the explanations have been hotly debated.
Avoiding Attack
This book discusses the evolution of the mechanisms by which prey avoid attack by their potential predators and questions how such defences are maintained through natural selection. Topics covered include camouflage, warning signals and mimicry.
Animal Camouflage
In the last decade, research on the previously dormant field of camouflage has advanced rapidly, with numerous studies challenging traditional concepts, investigating previously untested theories and incorporating a greater appreciation of the visual and cognitive systems of the observer. Using studies of both real animals and artificial systems, this book synthesises the current state of play in camouflage research and understanding. It introduces the different types of camouflage and how they work, including background matching, disruptive coloration and obliterative shading. It also demonstrates the methodologies used to study them and discusses how camouflage relates to other subjects, particularly with regard to what it can tell us about visual perception. The mixture of primary research and reviews shows students and researchers where the field currently stands and where exciting and important problems remain to be solved, illustrating how the study of camouflage is likely to progress in the future.
Avoiding Attack
Avoiding Attack discusses the diversity of mechanisms by which prey avoid predator attacks and explores how such defensive mechanisms have evolved through natural selection. It considers how potential prey avoid detection, how they make themselves unprofitable to attack, how they communicate this status, and how other species have exploited these signals. Using carefully selected examples of camouflage, mimicry, and warning signals drawn from a wide range of species and ecosystems, the authors summarise the latest research into these fascinating adaptations, developing mathematical models where appropriate and making recommendations for future study. This second edition has been extensively ...
Insect Behavior
Insects display a staggering diversity of behaviors. Studying these systems provides insights into a wide range of ecological, evolutionary, and behavioral questions including the genetics of behavior, phenotypic plasticity, chemical communication, and the evolution of life-history traits. This accessible text offers a new approach that provides the reader with the necessary theoretical and conceptual foundations, at different hierarchical levels, to understand insect behavior. The book is divided into three main sections: mechanisms, ecological and evolutionary consequences, and applied issues. The final section places the preceding chapters within a framework of current threats to human survival - climate change, disease, and food security - before providing suggestions and insights as to how we can utilize an understanding of insect behavior to control and/or ameliorate them. Each chapter provides a concise, authoritative review of the conceptual, theoretical, and methodological foundations of each topic.

Witchcraft Accusations and Persecutions as a Mechanism for the Marginalisation of Women
This books draws on feminist commentary from the disciplines of anthropology, history, law, politics and sociology in order to deal with the phenomenon of modern-day witchcraft. It focuses on the re-emergence of witchcraft beliefs in contemporary society, suggesting that witchcraft accusations and persecution are being used as a marginalisation mechanism of women. The re-emergence of witchcraft beliefs in contemporary society and the prevalence of the violence associated with such beliefs has received little attention within academic literature, yet witchcraft-related violence against women is, progressively, becoming one of the most pervasive forms of violence facing women today. This book addresses this gap in the literature, discussing the return of witchcraft beliefs to contemporary society, whilst assessing the effectiveness of international human rights law in protecting women from witchcraft accusations and persecution.
In Pursuit of Spring
Spring was late in 1913 and Edward Thomas decided to go and search for winter's grave and the tell-tale signs of season's turn - he set out to cycle westwards from London to the Quantocks. Edward Thomas 1878-1917 turned from writing prose to poetry in 1914. His work as a poet has been widely celebrated and admired - Ted Hughes described Thomas as "the father of us all". The Pursuit of Spring, originally published in 1914, bridges the divide between Thomas the journalist/critic and Thomas the highly regarded poet.
Evaluation and Development
Partnership is of growing importance in development work. Partnerships among state, private business, and civil society organizations are increasingly used to deliver the goods and services required for balanced growth and poverty reduction. Aid activities have shifted from a project focus to a more strategic and holistic focus on programs, sectors, and policies. With this new orientation, partnerships are often essential to deal with the added complexity and the larger number of agencies, groups, and stakeholders involved.The Partnership Dimension takes on the issues in a series of chapters divided into two general parts: Part 1, "Foundations of Partnership and Their Evaluation," covers the...
