Winner of the 2016 BES Marsh Christian Trust Book Award, British Ecological Association "[A]ll ecologists will benefit from reading [Mutualistic Networks], giving this audience a better understanding of the network perspective on mutualism."--Choice "Making a case for why we should care about mutualisms and their complex networks, this book offers a new perspective on the study and synthesis of this growing area for ecologists and evolutionary biologists. It will serve as the standard reference for any future work on mutualistic interactions in biological communities."--Biotechnology, Agronomy, Society and Environment "Mutualistic Networks is a book that presents a highly dynamic field in its entire breadth and historic development. [A]nyone interested in a passionate layout of a multifaceted and ecologically exciting research area will want to read it."--Carsten F. Dormann, Basic and Applied Ecology "[T]his excellent and unique book provides novel insights into ecological and coevolutionary dynamics of interacting species."--Wesley Dattilo, Journal of Complex Networks "Bascompte and Jordano ... logically and thoroughly guide the reader through the theories and tools used to understand, and the importance of understanding, the complexity of mutualistic networks."--Luke S. O'Loughlin, Austral Ecology
