Invasion Ecology

Julie L. Lockwood is a Professor at Rutgers University. Her research interests include conservation biology, population biology, and biological invasions.Martha F. Hoopes is an Associate Professor at Mount Holyoke College. She has worked primarily with plants and insects on questions of spatial community dynamics and invasions.Michael P. Marchetti is the Fletcher Jones Professor of Ecology at St. Mary’s College of California.He is an aquatic ecologist who primarily studies community and landscape aspects of freshwater invaders in the western U.S.

“Summing Up: Highly recommended.  Lower-division undergraduates through graduate students, researchers/faculty, land managers, policy makers, and interested general readers.”  (Choice, 1 February 2014)“Young scientists starting out in this field who read this book will not only gain an appreciation of our current state of knowledge, but, perhaps more importantly, will also learn where our knowledge is limited and what research questions are prime for tackling.”  (Biological Conservation, 1 January 2014)“This is certainly by far still the best introduction to this important topic around, and those that bought the first edition should snap this one up also for the increased topicality. The work is also available in various electronic formats, which should further encourage its take-up by the current student generation.”  (Biodivers Conserv, 1 September 2013)“Overall, I can fully recommend this book. As the 1st edition, this 2nd edition will be valuable for students, researchers, managers, and anybody else interested in bio- logical invasions. It reads very well and is technically well done; I spotted only few typos. The companion website (www.wiley.com/go/invasionecology) with down- loadable versions of the book’s figures and tables is also very useful.”  (Basic and Applied Ecology, 1 October 2013)
