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 ofspecies 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 rewritten, particularly in the application of modern genetic research techniques which have transformed our recent understanding of adaptations in evolutionary genomics and phylogenetics. The book also employs a more integrated and systematic approach, ensuring that each chapter has a broader focus on the evolutionary and ecological consequences of anti-predator adaptation. The field has grown and developed considerably over the last decade with anexplosion of new research literature, making this new edition timely.

In this thoroughly revised and updated second edition, William Allen and Carlos Vargas-Silva bring together a diverse range of experts to explore the latest research methods in migration studies, taking stock of major changes that have been salient for migration research—as well as the social sciences more broadly—in the last decade. Spanning a variety of different methodologies, this second edition of the Handbook of Research Methods in Migration provides practical guidance on designing, completing, and communicating migration research, considering diverse audiences including migrants themselves.Chapter authors reflect on and engage with trends of migration research, with seventeen new chapters covering developments in data sources, techniques, and practical issues impacting migration researchers. They assess quantitative methods, including surveys, conjoint analysis and satellite data, as well as qualitative methods such as archival research, language patterns and the use of social media. Ultimately, they consider the use of these methods in specific case studies, before focusing on how to address practical and ethical issues that can arise during the process of migration research.Expertly developing the ideas discussed in the first edition, this Handbook is a crucial resource for students and scholars of development studies, human geography and social science research methods. It also appeals to researchers working on migration in all its forms, as well as ethnicity, discrimination and demographic change.
