People sweat to stay cool. The water comes out of our skin. As it dries, it takes the heat from our body with it. This helps us to stay cool. If the water is not drying fast enough, we can sit in front of a fan. This takes the water off our bodies faster. If that is not enough, we can add more water to our skin. We do this by running through a sprinkler or going swimming. Now that is a lot of water on your body. And all of that water is taking away some of the heat. That is how we stay cool. But many animals do not sweat. They also do not have sprinklers they can run through! They have to find other ways to stay cool. Here is how they do it. Ages 7 to 12 and up.

Describes how animals adapt to survive, discussing camouflage, mimicry, poisons, defense, adaptations to weather, feeding, and mating.

A fun and factual exploration of how animals stay cool in hot weather

Why do zebras have stripes? Popular explanations range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack.

In this witty, accessible, and beautifully illustrated guide, Eleanor Spicer Rice, Alex Wild, and Rob Dunn metamorphose creepy-crawly revulsion into myrmecological wonder. Dr. Eleanor?s Book of Common Ants provides an eye-opening entomological overview of the natural history of species most noted by project participants. Exploring species from the spreading red imported fire ant to the pavement ant, and featuring Wild?s stunning photography, this guide will be a tremendous resource for teachers, students, and scientists alike. But more than this, it will transform the way we perceive the environment around us by deepening our understanding of its littlest inhabitants, inspiring everyone to find their inner naturalist, get outside, and crawl across the dirt?magnifying glass in hand.

The alarm calls of birds make them difficult for predators to locate, while the howl of wolves and the croak of bullfrogs are designed to carry across long distances. From an engineer's perspective, how do such specialized adaptations among living things really work? And how does physics constrain evolution, channeling it in particular directions? Writing with wit and a richly informed sense of wonder, Denny and McFadzean offer an expert look at animals as works of engineering, each exquisitely adapted to a specific manner of survival, whether that means spinning webs or flying across continents or hunting in the dark-or writing books. This particular book, containing more than a hundred illustrations, conveys clearly, for engineers and nonengineers alike, the physical principles underlying animal structure and behavior. Pigeons, for instance-when understood as marvels of engineering-are flying remote sensors: they have wideband acoustical receivers, hi-res optics, magnetic sensing, and celestial navigation. Albatrosses expend little energy while traveling across vast southern oceans, by exploiting a technique known to glider pilots as dynamic soaring. Among insects, one species of fly can locate the source of a sound precisely, even though the fly itself is much smaller than the wavelength of the sound it hears. And that big-brained, upright Great Ape? Evolution has equipped us to figure out an important fact about the natural world: that there is more to life than engineering, but no life at all without it.

In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.

More than ever, Americans care about the quality and safety of the food they eat. They're bringing back an American tradition: raising their own backyard chickens for eggs and companionship. And they care about the quality of life of their chickens. Fresh Eggs Daily is an authoritative, accessible guide to coops, nesting boxes, runs, breeding, feed, and natural health care with time-tested remedies. The author promotes the benefits of keeping chickens happy and well-occupied, and in optimal health, free of chemicals and antibiotics. She emphasizes the therapeutic value of herbs and natural supplements to maintaining a healthy environment for your chickens. Includes many "recipes" and 8 easy DIY projects for the coop and run. Full color photos throughout. The USDA's new study of urban chicken raising sees a 400% increase in backyard chickens over the next 5 years, driven by younger adults.
