   Before 1935, there were no cane toads in Australia. Today, they are a huge presence in the country. In fact, scientists estimate that there are 83 toads for every person there! The big amphibians—which can weigh close to three pounds—show up on highways, in watering holes meant for cattle, and in people's yards in town. Because they ooze a powerful poison when attacked, they kill many wild animals as well as pets each year. In Australia's Cane Overrun, students will learn all about these troublesome creatures. The fascinating account describes why and how the toads were first brought to Australia, how they spread far and wide, and what scientists and everyday people are doing to try to control their population today. Large color photos, maps, and fact boxes enrich the dramatic details. Written in narrative format, this series is sure to keep young readers engaged.

   On the tropical island of Guam, there's a serious problem. It's long and brown and is slithering everywhere--including inside people's houses! The brown tree snake first arrived in Guam in the 1940s after hitching a ride on a ship sailing from the South Pacific. It found a new island home that was warm, had lots of food, and was free of predators. The snake multiplied quickly--and now millions roam Guam, devouring every small animal in their path and causing major environmental problems. In Guam's Brown Tree Snakes: Hanging Out, students will learn all about these animal invaders. The fascinating account describes how brown tree snakes first arrived in Guam, how they spread throughout the island, how they are affecting native wildlife and people, and what scientists are doing to control their population and stop them from spreading to other places. Large color photos, maps, and fact boxes enrich the dramatic details. Written in narrative format, this series is sure to keep young readers engaged.
