Unlike their human counterparts, who must alter their environment to accommodate our physical limitations, animals are adaptable to an amazing range of conditions--i.e., radical changes in a creature's physiology take place to match the demands of the environment. Winter provides an especially remarkable situation, because of how drastically it affects the most elemental component of all life: water.Examining everything from food sources in the extremely barren winter landscape to the chemical composition that allows certain creatures to survive, Heinrich's Winter World awakens the largely undiscovered mysteries by which nature sustains herself through the harsh, cruel exigencies of winters

    Color photographs and line drawings help you identify and learn about the fascinating plants of the Pacific Northwest coast.

    It features a durable vinyl biding, color plates visually arranged by shape and color, and thumb-tab silhouettes for quick and easy identification of butterflies in the field. The species account for each butterfly provides measurements, descriptions of each stage of the life cycle, and information on coloring or distinguishing markings, flight period, habitat, and range.

    From Hindu mythology to Aztec sacrifices, butterflies have served as a metaphor for resurrection and transformation. Even during World War II, children in a Polish death camp scratched hundreds of butterflies onto the walls of their barracks. But as Russell points out in this rich and lyrical meditation, butterflies are above all objects of obsession. From the beastly horned caterpillar, whose blood helps it count time, to the peacock butterfly, with wings that hiss like a snake, Russell traces the butterflies through their life cycles, exploring the creatures' own obsessions with eating, mating, and migrating. In this way, she reveals the logic behind our endless fascination with butterflies as well as the driving passion of such legendary collectors as the tragic Eleanor Glanville, whose children declared her mad because of her compulsive butterfly collecting, and the brilliant Henry Walter Bates, whose collections from the Amazon in 1858 helped develop his theory of mimicry in nature. Russell also takes us inside some of the world's most prestigious natural history museums, where scientists painstakingly catalogue and categorize new species of Lepidoptera, hoping to shed light on insect genetics and evolution. A luminous journey through an exotic world of obsession and strange beauty, this is a book to be treasured by anyone who's ever watched a butterfly mid-flight and thought, as Russell has, "I've entered another dimension."

    But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity.There is an unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. In many parts of the world, habitat destruction has been so extensive that local wildlife is in crisis and may be headed toward extinction.Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and the new paperback edition—with an expanded resource section and updated photos—will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.
