Book Description
All bodily activity is the result of the interplay of vastly complex physiological processes, and all of these processes depend on temperature. For insects, the struggle to keep body temperature within a suitable range for activity and competition is often a matter of life and death. A few studies of temperature regulation in butterflies can be found dating back to the late 1800s, but only recently have scientists begun to study the phenomenon in other insects. In The Thermal Warriors Bernd Heinrich explains how, when, and in general what insects regulate their body temperature and what it means to them. As he shows us, the ingenuity of the survival strategies insects have evolved in the irreducible crucible of temperature is astonishing: from shivering and basking, the construction of turrets (certain tiger beetles), and cooling with liquid feces to stilting (some desert ants and beetles), "panting" in grasshoppers and "sweating cicada," and counter- and alternating-currents of blood flow for heat retention and heat loss. In The Thermal Warriors Heinrich distills his great reference work, The Hot-Blooded Insects, to its essence: the most significant and fascinating stories that illustrate general principles, all conveyed in the always engaging prose we have come to expect from this author.

Book Description
This book is a comprehensive guide to the natural history of the North Slope, the only arctic tundra in the United States. The first section provides detailed information on climate, geology, landforms, and ecology. The second provides a guide to the identification and natural history of the common animals and plants and a primer on the human prehistory of the region from the Pleistocene through the mid-twentieth century. The appendix provides the framework for a tour of the natural history features along the Dalton Highway, a road connecting the crest of the Brooks Range with Prudhoe Bay and the Arctic Ocean, and includes mile markers where travelers may safely pull off to view geologic formations, plants, birds, mammals, and fish. Featuring hundreds of illustrations that support the clear, authoritative text, Land of Extremes reveals the arctic tundra as an ecosystem teeming with life.

Book Description
From flying squirrels to grizzly bears, and from torpid turtles to insects with antifreeze, the animal kingdom relies on some staggering evolutionary innovations to survive winter. Unlike their human counterparts, who must alter the environment to accommodate physical limitations, animals are adaptable to an amazing range of conditions. Examining everything from food sources in the extremely barren winter land-scape 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 winter's harsh, cruel exigencies.

Book Description
Glimpses of Creatures in Their Physical Worlds offers an eye-opening look into how the characteristics of the physical world drive the designs of animals and plants. These characteristics impose limits but also create remarkable and subtle opportunities for the functional biology of organisms. In particular, Steven Vogel examines the size and scale, and trade-offs among different physical processes. He pays attention to how the forms and activities of animals and plants reflect the materials available to nature, and he explores the unique constraints and possibilities provided by fluid flow, structural design, and environmental forces. Each chapter of the book investigates a facet of the physical world, including the drag on small projectiles; the importance of diffusion and convection; the size-dependence of acceleration; the storage, conduction, and dissipation of heat; the relationship among pressure, flow, and choice in biological pumps; and how elongate structures tune their relative twistiness and bendiness. Vogel considers design-determining factors all too commonly ignored, and builds a bridge between the world described by physics books and the reality experienced by all creatures. Glimpses of Creatures in Their Physical Worlds contains a wealth of accessible information related to functional biology, and requires little more than a basic background in secondary-school science and mathematics. Drawing examples from creatures of land, air, and water, the book demonstrates the many uses of biological diversity and how physical forces impact biological organisms.

Book Description
Expanded Third Edition with Marine Martial Art Update. In a top-secret U.S. military experiment, Richard Heckler was invited to teach Eastern awareness disciplines ranging from Aikido to meditation to a group of 25 Green Berets. This account chronicles his experiences in the training program and his attempts to revive traditional warriorship in a technological society. His book provides insight into the nature of war, the meaning of masculinity, and the need for moral values in the military. This new edition includes Heckler's response to 9/11, his connections to the Pentagon and U.S. soldiers in Afghanistan, and his reflections on the movie Black Hawk Down, which depicts the deaths of two of his trainees. The new Marine Corps martial art...is focused as much on the soul as it is on soldiering... --The Wall Street Journal
