Invasion biology -- both the book & the field -- is an interesting mixture of biology, ecology, and conservation management. mark Davis is one of the key people in the field, albeit that sometimes his ideas are controversial. A great introduction to the field with enough depth to lead you into more specifics. Really a good and important book.
When the author sticks to the science this is a really good review of invasive species, neobiotia, or whatever one wants to call it. He has an academic's interest in defining words: non native, versus alien versus non indigenous etc which is interesting although I am not sure how it moves the science forward. I wish he had spent the same amount of effort covering the literature, although given how much of it there is that is probably unfair to ask. He sets high standards when discussing the work of others but when he gets to his own opinions he feels free to ramble and opine. The book needed a good editor. If I had been one, I would not have indulged the author's ex cathedra proclivities in Part III or at least would have reduced them to a single chapter. Finally he is definitely part of the establishment , based on his recent unrefereed opinion piece in Nature with all his senior coauthors, so the young Turk approach is a big precious.
The author of this book is extremely incompetent, can't get a clear word out, and has to reference 3 different studies before he makes a complete thought. It feels like i'm reading a gifted 8th graders research paper. What garbage, he should be ashamed to have this book associated with his name.
