WASSALL, Erika

In a series covering species that act as "canaries in a coalmine" for particular habitats, these books discuss how threats such as pollution, use of pesticides, and habitat loss have decreased these insects' populations, and why monitoring them is important. Photos, maps, and graphs break up the accessible texts; researchers may find the Common Core–focused sections with reading-comprehension questions, prompts, and links distracting. Reading list. Glos., ind. Review covers these Bioindicator Species titles: Dragonflies Matter. Monarch Butterflies Matter, and Bees Matter.
