Objects in harmonic motion have the ability to transfer some of their energy over large distances. Light Nature: This chapter covers the nature of light, polarization, and color.

    Today there are three cats for every dog on the planet, and yet cats remain more mysterious, even to their most adoring owners. Unlike dogs, cats evolved as solitary hunters, and, while many have learned to live alongside humans and even feel affection for us, they still don’t quite get us” the way dogs do, and perhaps they never will. But cats have rich emotional lives that we need to respect and understand if they are to thrive in our company.In Cat Sense, renowned anthrozoologist John Bradshaw takes us further into the mind of the domestic cat than ever before, using cutting-edge scientific research to dispel the myths and explain the true nature of our feline friends. Tracing the cat’s evolution from lone predator to domesticated companion, Bradshaw shows that although cats and humans have been living together for at least eight thousand years, cats remain independent, predatory, and wary of contact with their own kind, qualities that often clash with our modern lifestyles. Cats still have three out of four paws firmly planted in the wild, and within only a few generations can easily revert back to the independent way of life that was the exclusive preserve of their predecessors some 10,000 years ago. Cats are astonishingly flexible, and given the right environment they can adapt to a life of domesticity with their owners—but to continue do so, they will increasingly need our help. If we’re to live in harmony with our cats, Bradshaw explains, we first need to understand their inherited quirks: understanding their body language, keeping their environments—however small—sufficiently interesting, and becoming more proactive in managing both their natural hunting instincts and their relationships with other cats.A must-read for any cat lover, Cat Sense offers humane, penetrating insights about the domestic cat that challenge our most basic assumptions and promise to dramatically improve our pets’ lives—and ours.

    From the world’s most painful hornet, to the flies that transmit deadly diseases, to millipedes that stop traffic, to the “bookworms” that devour libraries, to the Japanese beetles munching on your roses, Wicked Bugs delves into the extraordinary powers of many-legged creatures. With wit, style, and exacting research, Stewart has uncovered the most terrifying and titillating stories of bugs gone wild. It’s an A to Z of insect enemies, interspersed with sections that explore bugs with kinky sex lives (“She’s Just Not That Into You”), creatures lurking in the cupboard (“Fear No Weevil”), insects eating your tomatoes (“Gardener’s Dirty Dozen”), and phobias that feed our (sometimes) irrational responses to bugs (“Have No Fear”). Intricate and strangely beautiful etchings and drawings by Briony Morrow-Cribbs capture diabolical bugs of all shapes and sizes in this mixture of history, science, murder, and intrigue that begins—but doesn’t end—in your own backyard.

    Lying in the eastern Pacific Ocean, straddling the equator off the west coast of South America, the Galágos is the most pristine archipelago to be found anywhere in the tropics. It is so remote, so untouched, that the act of wading ashore can make you feel like you are the first to do so. Yet the Galágos is far more than a wild paradise on earth-it is one of the most important sites in the history of science. Home to over 4,000 species native to its shores, around 40 percent of them endemic, the islands have often been called a "laboratory of evolution." The finches collected on the Galágos inspired Darwin's revolutionary theory of natural selection. In The Galágos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its course from deserted wilderness to biological testing ground and global ecotourism hot spot. Describing the island chain's fiery geological origins as well as our species' long history of interaction with the islands, he draws vivid portraits of the life forms found in the Galágos, capturing its awe-inspiring landscapes, understated flora, and stunning wildlife. Nicholls also reveals the immense challenges facing the islands, which must continually balance conservation and ever encroaching development. Beautifully weaving together natural history, evolutionary theory, and his own experience on the islands, Nicholls shows that the story of the Galágos is not merely an isolated concern, but reflects the future of our species' relationship with nature-and the fate of our planet.

    . . . This is an exciting book. Although Schaller feels that this is 'not an adventure book,' few readers will be able to agree."—Irven DeVore, Science

    Most of us appreciate that at some level. But what does it mean for us to have more in common with a horse and an elephant than we do with a parrot, snake or frog?After a misdirected football left new father Liam Drew clutching a uniquely mammalian part of his anatomy, he decided to find out more. Considering himself as a mammal first and a human second, Liam delves into ancient biological history to understand what it means to be mammalian.In his humorous and engaging style, Liam explores the different characteristics that distinguish mammals from other types of animals. He charts the evolution of milk, warm blood and burgeoning brains, and examines the emergence of sophisticated teeth, exquisite ears, and elaborate reproductive biology, plus a host of other mammalian innovations. Entwined are tales of zoological peculiarities and reflections on how being a mammal has shaped the author's life.I, Mammal is a history of mammals and their ancestors and of how science came to grasp mammalian evolution. And in celebrating our mammalian-ness, Liam Drew binds us a little more tightly to the five and a half thousand other species of mammal on this planet and reveals the deep roots of many traits humans hold dear.

    The bonobo, least known of the great apes, is a female-centered, egalitarian species that has been dubbed the "make-love-not-war" primate by specialists. In bonobo society, females form alliances to intimidate males, sexual behavior (in virtually every partner combination) replaces aggression and serves many social functions, and unrelated groups mingle instead of fighting. The species's most striking achievement is not tool use or warfare but sensitivity to others.In the first book to combine and compare data from captivity and the field, Frans de Waal, a world-renowned primatologist, and Frans Lanting, an internationally acclaimed wildlife photographer, present the most up-to-date perspective available on the bonobo. Focusing on social organization, de Waal compares the bonobo with its better-known relative, the chimpanzee. The bonobo's relatively nonviolent behavior and the tendency for females to dominate males confront the evolutionary models derived from observing the chimpanzee's male power politics, cooperative hunting, and intergroup warfare. Further, the bonobo's frequent, imaginative sexual contacts, along with its low reproduction rate, belie any notion that the sole natural purpose of sex is procreation. Humans share over 98 percent of their genetic material with the bonobo and the chimpanzee. Is it possible that the peaceable bonobo has retained traits of our common ancestor that we find hard to recognize in ourselves?Eight superb full-color photo essays offer a rare view of the bonobo in its native habitat in the rain forests of Zaire as well as in zoos and research facilities. Additional photographs and highlighted interviews with leading bonobo experts complement the text. This book points the way to viable alternatives to male-based models of human evolution and will add considerably to debates on the origin of our species. Anyone interested in primates, gender issues, evolutionary psychology, and exceptional wildlife photography will find a fascinating companion in Bonobo: The Forgotten Ape.

Never has a scientist been so truthful in capturing in words the flavor of his work.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    Her twenty- five-year career conducting experiments that involve rats has led her to a surprising conclusion: Through their adaptive strategies and good habits, these unassuming little animals can teach us some essential lessons about how we, as humans, can lead successful lives. From emotional resilience and a strong work ethic to effective parenting and staying healthy, the lab rat is an unlikely but powerful role model for us all. This is a surprising and engaging guided tour into the sophisticated mental, emotional, and behavioral worlds of these frequently maligned and often misunderstood little creatures.
