New Inquiry Figures focus students on the experimental process, and new Research Method Figures illustrate important techniques in biology. Each chapter ends with a Scientific Inquiry Question that asks students to apply scientific investigation skills to the content of the chapter.

    These fascinating, enigmatic creatures are a key lynchpin in the working of our planet. Without them the landscape, as well as every aisle in our supermarkets would look radically different. And we're not just talking about honey bees. There are more than 20,000 species of bee worldwide and only a handful make honey. Some live in colonies and others are solitary. We can all help protect them - and they desperately need protecting - but you can't save what you don't love. And you can't love what you don't know. The Good Bee is a celebration of this most vital and mysterious of nature's wizards. Here you'll discover the complexities of bee behaviour - as well as the bits that still baffle us - the part they play in the natural world, their relationship with us throughout history, how they are coming under threat and what we can all do about it.Beautifully produced, with hand-made illustrations throughout, it is a story for our times and a book to treasure.

    The book uses the theme of evolution to develop a broad-scale view of animal diversity--students focus not only the organisms themselves, but also the processes that produce evolutionary diversity. The book is unique in its comprehensive survey of zoological diversity and its emphasis on evolutionary, systematic and ecological principles, all in one package.

    He was a guy who rarely cycled or had an adventure, a guy who was scared of the fairground rides as a child. But one day he changed; he became a guy with a quest. Armed with a bicycle, a toy bear and some optimism he flew to the north of Alaska and for the next two years rode it to the southern tip of South America in Argentina. This is his tale.

    From menacing moonshiners and armed bandits to charging elephants and man-eating tigers, Merlin Tuttle has stopped at nothing to find and protect bats on every continent they inhabit. Enamored of bats ever since discovering a colony in a cave as a boy, Tuttle saw how effective photography could be in persuading people not to fear bats, and he has spent his career traveling the world to document them.Few people realize how sophisticated and intelligent bats are. Tuttle shares research showing that frog-eating bats can identify frogs by their calls, that vampire bats have a social order similar to that of primates, and that bats have remarkable memories. Bats also provide enormous benefits by eating crop pests, pollinating plants, and carrying seeds needed for reforestation. They save farmers billions of dollars annually and are essential to a healthy planet.Sharing highlights from a lifetime of adventure and discovery, Tuttle takes us to the frontiers of bat research and conservation and forever changes the way we see these poorly understood yet fascinating creatures.

    What he found in Brazil's thorny caatinga woodlands would one day transform our understanding about evolution, survival, and -- in the case of the long-tailed blue parrot now known as "Spix's Macaw" -- extinction. In this fascinating natural history, esteemed environmentalist Tony Juniper brings the caatinga bird beautifully to life. Not long after Spix's discovery, his parrot -- whose beauty, dexterity, and clear-eyed passion made it a favorite among scientists and bounty hunters alike -- had become more valuable than heroin, and worth thousands of dollars on the black market. By 1990, only one lone male was known to be living in the wild. Spix's Macaw tells the tale of Juniper's race to save the species, from joining an international rescue operation in the caatinga to calling on private collectors to mate their illegal birds to waiting in vain for a hybrid nest of eggs to hatch. His story brings new meaning to Emily Dickinson's poem "Hope Is the Thing with Feathers." A heart-stopping homage to the long, lonely flight of the last Spix's Macaw, this is a compassionate addition to the annals of nature literature and an environmental parable for our time.

    Mastering the fat hormone leptin is the single most important factor in preventing obesity, diabetes, and heart disease. The Leptin Diet contains five simple lifestyle guidelines to get the hormone leptin into balance for permanent weight loss, increased energy, and optimum health. What is Leptin? Fat cells produce the powerful hormone leptin, a primary force instructing metabolism, weight loss, and hormone balance. Leptin communicates directly to your brain, telling the brain how much fat is in storage. It controls appetite, energy, and metabolic rate. Leptin problems are the primary reason for food cravings, overeating, faulty metabolism, the obsession with food, and heart disease. Read The Leptin Diet and notice the difference!

    He has journeyed to the remote corners of the earth in search of wild things, weathering treacherous terrain, plane crashes, and hostile governments. Life in the Valley of Death recounts his most ambitious and dangerous adventure yet: the creation of the world's largest tiger preserve.The tale is set in the lush Hukaung Valley of Myanmar, formerly known as Burma. An escape route for refugees fleeing the Japanese army during World War II, this rugged stretch of land claimed the lives of thousands of children, women, and soldiers. Today it is home to one of the largest tiger populations outside of India—a population threatened by rampant poaching and the recent encroachment of gold prospectors.To save the remaining tigers, Rabinowitz must navigate not only an unforgiving landscape, but the tangled web of politics in Myanmar. Faced with a military dictatorship, an insurgent army, tribes once infamous for taking the heads of their enemies, and villagers living on less than one U.S. dollar per day, the scientist and adventurer most comfortable with animals is thrust into a diplomatic minefield. As he works to balance the interests of disparate factions and endangered wildlife, his own life is threatened by an incurable disease.The resulting story is one of destruction and loss, but also renewal. In forests reviled as the valley of death, Rabinowitz finds new life for himself, for communities haunted by poverty and violence, and for the tigers he vowed to protect.

    Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower.- A dichotomous key to all the species described in the book is designed to narrow the choices to a few possible species. Identification can then be confirmed by reading the descriptions of the species and comparing a specimen with the drawings and photographs.- A fold-out grass identification table provides diagnostic information for weedy grasses in an easy-to-use tabular key.- Specimens with unusual vegetative characteristics, such as thorns, square stems, whorled leaves, or milky sap, can be rapidly identified using the shortcut identification table.The first comprehensive weed identification manual available for the Northeast, this book will facilitate appropriate weed management strategy in any horticultural or agronomic cropping system and will also serve home gardeners and landscape managers, as well as pest management specialists and allergists.

    For their trail horses, they adopted wild mustangs from the US Bureau of Land Management that were perfectly adapted to the rocky terrain and harsh conditions of desert and mountain travel. A meticulously planned but sometimes unpredictable route brought them face to face with snowpack, downpours, and wildfire; unrelenting heat, raging rivers, and sheer cliffs; jumping cactus, rattlesnakes, and charging bull moose; sickness, injury, and death. But they also experienced a special camaraderie with each other and with the mustangs. Through it all, they had a constant traveling companion—a cameraman, shooting for the documentary film Unbranded. The trip’s inspiration and architect, Ben Masters, is joined here by the three other riders, Ben Thamer, Thomas Glover, and Jonny Fitzsimons; two memorable teachers and horse trainers; and the film’s producers and intrepid cameramen in the telling of this improbable story of adventure and self-discovery.

    Two days later, she got her first glimpse of the famous, terrifying jaws up close and she was instantly hooked; her fascination soon yielded to obsession-and an invitation to return for a full season. But as Casey readied herself for the eight-week stint, she had no way of preparing for what she would find among the dangerous, forgotten islands that have banished every campaign for civilization in the past two hundred years.
