From the reviews of the second edition:
There is a continual need for current introductory material in key ecological areas. ... This is an interesting text. It has a wealth of detail ... that means it is for the more 'advanced' beginner. ... However, it does provide both teachers and field study centres with a much-needed overview of stream ecology. ... Overall, a must for the field centre and a good starter text in stream ecology. (TEN News, October, 2007)
Allan and Castillo offer this superb compilation of both the latest and time-honored concepts of the ecology of fluvial systems at scales ranging from small mountain brooks to large, continental- sized river basins. Richly illustrated and with more than 1,500 reference citations, the book is divided into 14 chapters ... . Best of all, the book is written in a lively, engaging manner and with remarkable clarity, given the technical nature of the material. Summing Up: Highly recommended. Upper-division undergraduates through faculty. (P. R. Pinet, CHOICE, Vol. 45 (7), 2008)
The second edition of the book 'Stream Ecology' covers the key ecological factors and processes in a very variable ecosystem ... . I recommend 'Stream Ecology' to people with knowledge of the basics of ecology, e.g., graduates and advanced undergraduates ... . To my knowledge, there is no other book available, which gives such a good overview of the issue. One gets a very good, fluidly readable book which contains the latest key scientific knowledge of the ecology of running waters.
