The Geographic Mosaic of Coevolution by Ethan J. Temeles is a comprehensive review of the theory of coevolution, emphasizing the role of geographic variation in shaping evolutionary interactions. The book explores how coevolutionary processes occur at different scales and how geographic factors influence the dynamics of coevolutionary interactions. Thompson's theory, known as the Geographic Mosaic of Coevolution (GMTC), posits that coevolution is not uniform but varies across different regions and populations. The theory suggests that natural selection differs among populations due to varying interactions between species, and that reciprocal selection occurs only in certain local communities, creating a mosaic of coevolutionary hotspots and coldspots. The book also discusses the implications of these interactions for the evolution of traits and the dynamics of sexual reproduction. Thompson's theory is supported by evidence from various ecological interactions, including those between plants and pollinators, and between predators and prey. The book also addresses the challenges of studying coevolution, including the difficulty of identifying reciprocal selection and the need for large-scale studies to capture the full scope of coevolutionary processes. The book is praised for its comprehensive coverage of coevolutionary interactions and its contribution to the understanding of evolutionary dynamics. It is recommended for graduate-level seminars and is considered an important addition to institutional libraries. The book also includes a discussion of applied coevolutionary biology, highlighting the impact of human activities on coevolutionary dynamics. Overall, the book provides a detailed and insightful exploration of coevolutionary processes and their significance in the broader context of evolutionary biology.The Geographic Mosaic of Coevolution by Ethan J.
