Many kids are familiar with zoos, but there's much more to these attractions than an opportunity to see animals up close. Newman shines a light on the important work zoo scientists do to aid conservation and contribute important research, both at zoo labs and in the wild. This engagingly written book focuses on three scientists and their work protecting and researching orangutans, black-footed ferrets, and black rhinoceroses, respectively. Each scientist describes his or her background, research in the wild, challenges to conservation efforts, and how zoo labs help them do their work. Photos of the scientists in the field, as well as their animal research subjects, enlivens the already fascinating material. Newman clearly describes the conditions that led to each species becoming endangered and encourages readers to think carefully about their own actions in light of threats to wildlife. Though the book appears slim, the content is fairly dense, so this will likely appeal more to middle-grade readers. Hand this to kids who can't get enough of the Scientists in the Field series.

Readers see the human side of animal science.Newman brings scientific research to life with her lively introduction to three scientists active today, two women and one man, all white and from the United States. The National Zoo's Meredith Bastian's "wild perspective" was an important factor in her hiring, first by the Philadelphia Zoo and then by her current employer. Her experiences in Borneo led to conservation efforts that include educating zoo visitors about using palm oil products from companies that do not harm orangutan environments. She has also advocated for the installation of "overhead trails," resembling ziplines, that allow "orangutans to travel much like wild ones do." In writing about the Lincoln Park Zoo's Rachel Santymire's work in South Africa, Newman describes how "male black rhinos scrape their feces into long trenches" to mark their territory, while "females scrape to look for a mate—kind of like posting a profile on a dating website." The Cheyenne Mountain Zoo's Jeff Baughman doesn't just breed black-footed ferrets; he reintroduces these small mammals back into the wild, helping to build up a population that numbered only 18 in 1984. With engaging photos, useful charts and maps, and practical conservation tips, this volume provides lots of encouragement for budding young scientists. Three experts, three species, three zoos: these elements add up to a fascinating story of how specialists make a real difference in conservation today.

Gr 3-5In this incredibly informative book, readers learn about three zoo scientists who are working to save three species (orangutans, black-footed ferrets, and wild black rhinos) using a variety of methods, from conservation education to breeding programs. Newman also includes ideas on how students can contribute to conservation efforts, such as reducing palm oil usage. Various zoos and organizations that focus on conservation are also mentioned; for example, biobanks, where scientists freeze the sperm and eggs of various species in order to protect it from a catastrophic loss. The photographs show the animals as well as the scientists and effectively enhance the information presented. Several charts, including one comparing apes and monkeys, add a deeper level of understanding. Maps of the original and current habitats of the creatures are helpful in visualizing how the earth has changed over the years. VERDICT A great book for research or for students interested in conservation.V. Lynn Christiansen, Wiley International Studies Magnet Elementary School, Raleigh, NC
