Grade 3-6 Collard begins each clear and engaging title by introducing one or two scientists working in the field. As he explains their research, he incorporates general information about the topic. Deep Sea focuses on Edith Widder's experiments with bioluminescence and provides basic facts about marine creatures with that characteristic. In the Wild explores the work of wildlife researchers employed by Zoo Atlanta to help save endangered primates. Each well-designed volume has numerous color photographs and suggestions for further information, but most of the Web sites listed are for adults. Collard's Lizard Island (2000) and Monteverde (1997, both Watts), for older readers, include sections on the same scientists featured in Coral Reefs and Rain Forest Canopy.
