Jens put this link online in another forum. The book is online in Spanish but the pictures are worthy a look even if you don't read Spanish:-

There is a printed version (in Spanish) that can be obtained from Florencia Senoret at the contact email given on the first pages of the download.

Great book and amazing habitat pictures. It's worth checking this! Also, for anyone who in interested in reading it, you might want to try usint the "Adobe Reader Translator Plugin", just search for it on the web and install it, translation shouldn't be perfect but you can still understand most of the texts.
