This book focuses on the forgotten people displaced by, or living on the edge of protected wildlife areas. It moves beyond the grand ‘enchanting promise’ of conservation and development across frontiers, and unfounded notions of transfrontier conservation areas as integrated social-ecological systems. Peoples' dependency on natural resources varies enormously along the conservation frontier, as does their reliance on resources on the other side of the conservation boundary. Hence, the studies in this book move from the dream of ecotourism-fuelled development supporting nature conservation and people, towards the local realities facing marginalized people, living adjacent to protected areas in environments often poorly suited to agriculture.
In order to understand their research organisms, primatologists — at least those focussing on the ecology and natural behaviour of primates — need to understand the ecological context in which primates live. Furthermore, a comparative perspective, both between different primate radiations and between primates and non-primate animals, can help to better understand the specific adaptations of primates. However, in a scientific world with an ever increasing amount of information, obtaining concise and accurate updates that provide the broader picture becomes increasingly demanding. Therefore, books like the one that is reviewed here are highly welcome.
The authors of this book are renowned tropical ecologists, and the first author has also worked in the field of primate ecology (e.g. Corlett & Lucas 1990; Lucas & Corlett 1992). This book is the second edition, but it is not only updated but also augmented in scope. It is divided into nine chapters, one of which is focusing on primates (chapter 3: “Primate communities: a key to understanding biogeography and ecology”). The first chapter deals with a general introduction and highlights the similarities and differences among tropical rainforests. Chapter 2 describes the “Building blocks of the rain forest”, i.e. the distribution and taxonomic and structural diversity of tropical plant communities. While chapter 4 focuses on carnivores and plant-eaters (other than primates), chapters 5–7 are dedicated to the comparison of bird, bat and gliding animal, and insect communities in the different tropical regions. The final two chapters deal with rainforests on tropical islands, and with the future of tropical rain forests. Each chapter ends with conclusions and suggestions for further research directions.
This book is not (and certainly was never intended as) an exhaustive treatment of all aspects of tropical ecology and biogeography. But its comparative approach, the strong emphasis given to biotic interactions (e.g. seed dispersal, herbivory) and the exemplary treatment of ecological phenomena with examples from organisms that are best suited for highlighting the respective phenomenon make it a highly instructive reading. The book is generally well edited (despite a few disturbing spelling errors, e.g. Tarsium instead of Tarsius, p. 78). The writing style is very accessible, and the quality of figures (many of which are in colours) is excellent. Twenty pages with references (many of them quite recent) provide fodder for more detailed reading.
I enjoyed reading this book and recommend it to every primatologist who wants to look beyond the primatological horizon and update his/her knowledge in comparative tropical ecology and biogeography.

Appendices
A new novel highlights a landmark conservation success story Thirteen Gold Monkeys, by noted conservationist Benjamin B. Beck, is a story of hope, love, and unspeakable death in a disappearing Brazilian rainforest. A team of dogged conservationists tries to save a beautiful monkey species, the golden lion tamarin, from certain extinction by reinforcing their numbers with tamarins born in zoos. Will these immigrants learn to find enough to eat, find secure places to sleep, avoid predators, and survive attacks by wild tamarins? Will they find mates and make babies? The technique, known as reintroduction, is new, and the conservationists struggle to find the best method. Can they train the tamarins in zoos to meet the challenges of the wild? Once the monkeys are released in the forest, should the people give them food, shoo away predators, rescue them if they get lost, and treat them if they are injured? Or should they be hands-off, letting the monkeys fend for themselves and become wild as quickly as possible? Beck describes the reintroduction of the first 13 tamarins, capturing their fierce determination to survive, their loves and conflicts, their nurturant families, adorable babies, hidden language, sometimes comical attempts to solve the problems of adapting, and the agonizing deaths of those who don't make it. He describes the power and beauty of the rainforest, and the loves, loyalties, conflicts, and sometimes comical bumbling by their human caretakers. Challenging their better-known bosses, two women, a zookeeper and a Brazilian field assistant, discover the right way to reintroduce the monkeys. But a well-known Rio citizen almost destroys the program in a callous act of vanity. The story is vivid and authentic; Beck was there and has studied animal thinking and monkey and ape conservation for more than 40 years.
Thirteen Gold Monkeys is available from Amazon (including a Kindle edition), Barnes and Noble (including a Nook edition), and www.outskirtpress.com/bookstore. It should be orderable from any bookseller. There will soon be an iTunes version for iPhone/iPad. Fifty percent of any profits from the sale of the book will be donated to the Devra G.
