Deserts cover about one third of the earth's surface and are the largest terrestrial ecosystem in the world. They are the only biome that is actually expanding, largely due to human activities and climate change. In the United States, six unique desert ecosystems stretch across the country: the Great Basin, Mojave, Chihuahuan, Sonoran, Peninsular, and the Painted Desert.
Both a travelogue and science writing, North American Deserts: Ecology of Our Arid Lands is a celebration of these ruthlessly beautiful landscapes. Readers will be transported from the enchanting saguaro forests of Arizona and the precipitous red walls of the Grand Canyon to the monotonous, yet impressive landscapes of Nevada's Great Basin and Texas' Chihuahuan Desert. More than 190 vivid, color photographs accompany the lively writing.
Biologist Sean P. Graham has extensive field experience in the deserts of the Southwest and Mexico, and in North American Deserts, he takes readers on a journey through both sides of the border. The first half of the book focuses on global climate patterns giving rise to desert regions, and it then delves into how plants and animals survive the physical and biological characteristics of these ecosystems. The second half, which is split into cold and warm regions, features portraits of each desert that explore the unique flora and fauna. Although the work is focused on deserts in the United States, it also surveys the semiarid landscapes that extend into Canada and Mexico.
Outdoor enthusiasts, national park visitors, and self-proclaimed desert rats will enjoy this reflective yet informative account of our North American deserts.
The captivating and beautifully illustrated true story of snakes in America.
125 million years ago on the floodplains of North America, a burrowing lizard started down the long evolutionary path of shedding its limbs. The 60-plus species of snakes found in Sean P. Graham's American Snakes have this ancestral journey to thank for their ubiquity, diversity, and beauty. Although many people fear them, snakes are as much a part of America's rich natural heritage as redwoods, bald eagles, and grizzly bears. Found from the vast Okefenokee Swamp to high alpine meadows, from hardwood canopies to the burning bottom of the Grand Canyon, these ultimate vertebrates are ecologically pivotal predators and quintessential survivors.
In this revelatory and engaging meditation on American snakes, Graham, a respected herpetologist and gifted writer,
- explains the everyday lives of American snakes, from their daily routines and seasonal cycles to their love lives, hunting tactics, and defensive repertoires
- debunks harmful myths about snakes and explores their relationship with humans
- highlights the contribution of snakes to the American wilderness
- tells tales of snake people--important snake biologists with inspiring careers
Neither a typical field guide nor an exhaustive reference, American Snakes is instead a fascinating study of the suborder Serpentes. Brimming with intriguing and unusual stories--of hognose snakes that roll over and play dead, blindsnakes with tiny vestigial lungs, rainbow-hued dipsadines, and wave-surfing sea-snakes--the text is interspersed with scores of gorgeous full-color images of snakes, from the scary to the sublime. This proud celebration of a diverse American wildlife group will make every reader, no matter how skeptical, into a genuine snake lover.
