ReviewedA group of gray wolves silently stalks prey. Once the pack picks one of the older animals in a herd, the apex predators take it down with the speed and strength that no single animal would have been able to manage. All around them, plant life grows lush, healthy bison roam the land, and an eagle picks apart leftovers from the pack’s last kill. Wolves are vital to their ecosystems, controlling the size of prey populations so all life can flourish. Uncover the truth about this important keystone species, explore how wolves shape entire ecosystems, and learn what’s at risk if these powerful predators disappear. Approachable text and engaging images bring this timely topic to life.
Each animal (plus one plant) is introduced primarily in terms of its crucial ecological role as a keystone species. In Sea Otters, for example, readers learn about the environmental importance of kelp forests, then discover the otters’ unique ability to hunt the sea urchins that feed on kelp. The second half of each book looks at threats to the keystone species, potential dangers if they can’t fill their roles, and efforts by humans to protect them. Clearly written text covers various ways that these species fit into their ecosystems. Prairie dogs, for instance, keep soil healthy, aiding grazers, birds, and insects, and also serve as the single food source for black-footed ferrets (Prairie Dogs). Large photographs depict the environments and the ways that animals interact with it. A final spread offers tips for readers to help preserve the species. VERDICT Clear, well-organized introductions to keystone species and their habitats.
