As the Earth’s temperature rises, pikas must keep movinghigher and higher up the mountains to find a cooler climate in which to live. Everything is connected in the naturalworld. As the pikas livable habitat decreases, the lives of hawks, falcons, pine martins, foxes and the many othercreatures that prey upon pikas are affected.If you are looking for an easily understandable introduction to the consequences of climate change, this is the book foryou. Glorious photographs and a well-organized text reveal the key role pikas play in the alpine ecosystem. Helpfuldiagrams demonstrate the food web that includes this tiny mammal and other plants and animals, also threatened by thechanging climate. A glossary, map and list of actions kids can take to help decrease climate change are also included.Free, downloadable activities can be found on the publisher's website.

Did you know that beaver ponds provide habitat for hundreds if not thousands of life forms?Using their extremely strong teeth, beavers chop down trees to build a dam. The dam creates a pond that is habitat for everything from algae to giant moose. After creating the pond, the beavers build a lodge. The lodge is sometimes used by other animals besides beavers. Muskrats may live inside the lodge either with or without the beavers, or geese may build their nest atop the lodge. The dam itself is used as a bridge to cross the water by deer, ducks or any other number of creatures. The pond is home to numerous life forms. Lily pads grow in the pond and frogs sit on lily pads to catch flies.Learn about the pivotal role beavers play in making all of this life possible. Gorgeous photos and inviting text make AT HOME WITH THE BEAVER: THE STORY OF A KEYSTONE SPECIES a must have for young naturalists hoping to learn more about the interconnectedness of life.Other Books in the Series: AT HOME WITH THE GOPHER TORTOISE: THE STORY OF A KEYSTONE SPECIES, AT HOME WITH THE PRAIRIE DOG: THE STORY OF A KEYSTONE SPECIES
