'… I find this book very helpful as a textbook on invasion ecology and ecology not only for the students of ecology, but also for the teachers or people from NGOs. … Although this book is written for beginners in ecology, it is not boring even for the advanced readers. By using plenty of examples such as case studies and recent references, the authors make the book suitable for a wider audience. The use of language that makes it easy to read for the non-native English speaking students is another reason why I recommend this book.' Folia Geobotanica
