(3) 4-6 The answers to why bee populations have dwindled are complicated, and Hirsch explains the processes scientists are using to identify causes of bee population decline. She also shares enough broader ecology to show why we should make it our beeswax to care about bees, with frequent sidebars, diagrams, and photos of bees and their habitats to sweeten the deal.

Each volume provides a basic definition of human-induced climate change, then considers the impact of rising temperatures and an increase in carbon dioxide on plant and animal life, weather, and humans, with only minor overlap of content across the books. Though the cases presented are dire, solutions and mitigation of negative impacts are considered. The high-quality images and layouts organize the material well. Reading list, timeline, websites. Glos., ind. Review covers these Searchlight Books: Climate Change titles: Climate Change and Air Quality, Climate Change and Extreme Storms, Climate Change and Energy Technology, Climate Change and Rising Sea Levels, Climate Change and Rising Temperatures, and Climate Change and Life on Earth.

(3) 4-6 Some methods of studying monarch butterfly migrations--such as tagging and measuring resting colonies--show that populations are decreasing, and Hirsch investigates why? A readable narrative, illustrated with excellent photos and infographics, discusses the environmental culprits (deforestation, herbicides, climate change) and how scientists are helping. Kids, too, can help conserve monarch populations with the appended "citizen scientist" suggestions. Reading list. Bib., ind.

(3) YA Advances in genetics allow scientists to consider the possibility of reviving extinct species. Hirsch delves deep into related topics, including evolution, mass extinction, reproduction, and genetic technologies. Case studies of animals such as woolly mammoths and passenger pigeons highlight the feasibility, as well as ethical considerations, of de-extinction. Detailed diagrams and illustrations step readers through the advanced material. Reading list, websites. Bib., glos., ind.

(3) YA The human body is covered, inside and out, with tiny microbes that are part of the body's ecosystem. Some cause disease, but most are important to human health. Hirsch clearly describes what scientists know about microbes, how the discoveries have been made, what is still unknown, and how antibiotic use affects the microbiome. Photos and informational sidebars are included. Bib., glos., ind.

(4) K-3 Comparing Animal Traits series. Each presentation covers appearance, habitat, skills, and traits for its subject while also comparing and contrasting the focal animal with other birds by text, photos, and charts. Some comparisons are natural, some surprisingly revealing; however, others--such as ruby-throated hummingbirds and Adélie penguins--feel random, without relevant comparative features. There are four other spring 2016 books in this series. Reading list, websites. Bib., glos., ind. Review covers these Comparing Animal Traits titles: Ruby-Throated Hummingbirds, Snowy Owls, Ostriches, and Toco Toucans.
