From the reviews: "The book is a collection of 25 papers submitted by attendees of the 2nd International Tagging and Tracking Symposium held in Spain in late 2007. ... Overall, this is a book for researchers and resource managers to find out what is being achieved with commercial tags. It is also a great way to catch up on what is new in a field which has seen a lot of activity in the last decade."--- (Mark Johnson, Aquatic Mammals, Vol. 37 (2), 2011)
