Naturalists London and Van Zyle follow a year in the life of a willow ptarmigan in this colorful picture book, providing young readers an introduction to the animal inhabitants of the far northern wilderness of Alaska and the Arctic. Full-color illustrations.

Text and illustrations showcase the willow ptarmigan, the state bird of Alaska.

From Paws IV, Alaska's favorite line of children's books, comes this delightful tale about the willow ptarmigan, Alaska's state bird. Illustrator Shannon Cartwright once again brings to the page and into kids' hearts a delightful tale about Alaska wildlife. In this new Paws IV book, a young girl plays hide-and-seek with a friendly ptarmigan on the Alaska Range. Season by season, the ptarmigan changes its plumage to blend with its surroundings, leaving the little girl wondering each time where it has disappeared to. Written in rhyming verse and filled with fascinating information about the ptarmigan, this charming book is ideal for reading aloud to young children.

High atop cascading waterfalls and deep within the lush green depths of the valleys, Swiss photographer Ruedi Homberger has for more than twenty years captured in photographs the majestic beauty of eastern Alaska's Wrangell Mountain range. In addition to summiting some of the Wrangells' loftiest peaks, Homberger has in recent years incorporated a technically challenging new approach into his work. Flying above the mountains in a small plane, Homberger literally goes to new heights to reveal a series of stunning aerial views. The first book-length collection of photographs focusing exclusively on the Wrangell-Saint Elias National Park and Preserve, My Wrangell Mountains offers readers a rare opportunity to "stand among the giants." Included in this magnificent oversized volume are nearly three hundred full-color photographs and an accompanying selection of sketches by award-winning illustrator Jon Van Zyle.

Winner of the 2010 Lane Anderson Award Drawing on breakthrough research in evolution, genetics, and on their extensive work in the field and lab, wildlife biologists John and Mary Theberge explain for non-scientists the real facts of life. Birds that suddenly grow gall bladders, when their species has none. Moose with antlers so big they encumber their movement through the forest. Butterflies that risk extinction by overwintering en masse. These are just a few stories the Theberges tell in their examination of what the mechanisms of evolution are and how they work. With examples from the very latest discoveries in genetics and ones they have made in their own field work, The Ptarmigan's Dilemma is a ground-breaking explanation of evolution for non-scientists. By marrying the separate sciences of ecology and genetics, the Theberges paint a picture far richer than either discipline can alone of how, for almost 4 billion years, life on Earth has evolved into the rich diversity that's under threat today. Along the way, they explain just what "the survival of the fittest" really means, how dramatic evolutionary changes can take place in just one generation, and how our too-little knowledge of or interest in how life on Earth organizes and supports itself is rapidly making us a danger to ourselves.
