"Life History Evolution" by Derek A. Roff is a comprehensive review of life history theory, integrating it with empirical findings from genetics and ecology. The book addresses the interface between these disciplines, highlighting their contributions to understanding life history evolution. Roff provides a framework for analysis, covering quantitative and population genetics, and defines fitness in various environmental contexts. He examines trade-offs, potential pitfalls in studying them, and methods to avoid these. The book discusses evolution in constant, stochastic, and predictable environments, with the latter focusing on adaptive responses to environmental variation. The final chapter outlines 20 topics for future research. While some may find the book theory-heavy or too genetics-focused, Roff effectively makes the theory accessible, covering essential issues and providing references for detailed information. The theory is linked to numerous empirical studies, though a separate book on empirical literature could complement this. Roff's discussion on fitness measures in density-dependent populations in stochastic environments is thorough and clear, with all key references included. The book also covers less familiar areas clearly and simply. A minor criticism is the long chapters, which make navigation difficult. Including section headings on the contents page would improve this. The book primarily uses the intrinsic rate of increase (r) and the Lotka equation, but a matrix formulation would be more useful for density-dependent populations and stochastic environments. Overall, the book is excellent, offering a single source of key theory and a route into the literature with a bibliography of over 1600 items. It should contribute significantly to advancing the field of life history evolution."Life History Evolution" by Derek A.
