'The book is a useful contribution for enlarging the published knowledge about general plant-insect interactions, with emphasis on the interactions at more trophic levels than is usually considered. The text is logically divided into a short introduction and three specialized parts … The structure of the book is straightforward: two chapters are devoted to branching processes overview, followed by more theoretical parts about models, and ending with three chapters full of examples and real data. The book can be used by many researchers and graduate students working on population dynamics … I appreciate that the text is written with respect to students and that the language used is also friendly for non-native English speaking readers. Thus this book is a good way to start understanding speciation. The target group, however, is not only students or evolutionary ecologists; I can also recommend this book to each institutional/university library and to many population biologists.'
