Billions have been spent on land conservation but too little attention had been paid to how cost-effective these investments have been. With budgets increasingly constrained, conservationists must learn to fully harness their funds to protect critical resources. Messer and Allen are pioneers in making conservation selection more successful, cost-effective, scientific, and transparent. This book introduces powerful mathematical tools available for project selection, using real-life examples and a practical step-by-step approach. Readers can readily apply these methods to their own work, accomplishing more with less by combining the individual benefits of structured decision-making, mathematical programming, and an understanding of market forces and human behavior. The authors highlight tools from conservation science, mathematics, land use planning and behavioral economics, showing how they can be combined to help protect key environmental resources. This is an invaluable volume for all students, professionals and stakeholders associated with conservation programs.

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 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 an explosion of new research literature, making this new edition timely.
