From New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, she has befriended octopuses with strikingly different personalities—gentle Athena, assertive Octavia, curious Kali, and joyful Karma. Each creature shows her cleverness in myriad ways: escaping enclosures like an orangutan; jetting water to bounce balls; and endlessly tricking companions with multiple “sleights of hand” to get food.Scientists have only recently accepted the intelligence of dogs, birds, and chimpanzees but now are watching octopuses solve problems and are trying to decipher the meaning of the animal’s color-changing techniques. With her “joyful passion for these intelligent and fascinating creatures” (Library Journal Editors’ Spring Pick), Montgomery chronicles the growing appreciation of this mollusk as she tells a unique love story. By turns funny, entertaining, touching, and profound, The Soul of an Octopus reveals what octopuses can teach us about the meeting of two very different minds.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

    In biology labs across the world, fruit flies are turning up answers to some of the basic questions of life. It's business as usual for the fly, which for generations has been defining biology's major landmarks. From genetics to development, behavior to aging, and evolution to the origin of species, the fruit fly has been a key player in some of the twentieth century's greatest biological discoveries.Techniques to pinpoint genes that play a role in human disease depend on genetic mapmaking principles first established with the fly. It was experiments on fruit flies that opened our eyes to the dangers of radiation to human health. In fact, everything from gene therapy to cloning to the Human Genome Project is built on the foundation of fruit fly research. Despite its many achievements, the fruit fly remains an unsung hero in the history of science. At last, here is a book that gives the fly its long overdue credit.In a highly original, witty, and irreverent style, Martin Brookes takes us through successive stages in the life cycle of the fly, each illustrating an important concept in biology. Some, such as the fundamentals of heredity, are well established; others, such as sexual warfare, learning, and memory, are still in their infancy. But whether flies are getting high on crack cocaine, enjoying the pleasures and pains of a boozy night out, being trained by punishment and reward, or struggling with insomnia, this book provides a glimpse of how one short life has informed almost every aspect of human existence. The result is a broad introduction to biology with insights into the practical realities of science.Often dismissed as irrelevant outside academic circles, the fruit fly, through this distinctive biography, will come to be recognized for what it really is: an icon of twentieth-century science and a window on our own biological world.

    The introduction contains illustrations of the main leaves, buds, and firs you are likely to find, and these provide the starting point for identification by leading you to a 'key' species.Within each tree family there is a list of key species and a guide to the most important features to look for when identifying a particular tree from that family. Then individual species are clearly described and a detailed illustration is given on the same page.Covering all the tree species found outside the major arboretums, from the olive tree to the eucalyptus, this is one of the most important tree guides to have appeared in the last 20 years. The illustrations are annotated with essential identification features, and the text highlights the most important things to look for to aid fast and accurate identification. There is also coverage of all the species native to Southern Europe.

    Cat lovers will be enthralled with his insights into the feline world, from the secret of catnip to the true meaning of a purr. Exploring the mysteries of animal communication, Caras explains cat vocabulary (nine consonants, five vowels) and the incredible phenomenon of psi-trailing, a cat's ability to find its way home after being transported several miles away. Filled with charming stories about the felines in his own life, the author helps us see wild and domestic cats for the remarkable creatures they are. The New York Times Book Review called this work, "As thorough and sensitive a tour of the cat's world as a human being can contrive".

    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.

    The roots of a tree indicate the sun’s direction; the Big Dipper tells the time; a passing butterfly hints at the weather; a sand dune reveals prevailing wind; the scent of cinnamon suggests altitude; a budding flower points south. To help you understand nature as he does, Gooley shares more than 850 tips for forecasting, tracking, and more, gathered from decades spent walking the landscape around his home and around the world. Whether you’re walking in the country or city, along a coastline, or by night, this is the ultimate resource on what the land, sun, moon, stars, plants, animals, and clouds can reveal—if you only know how to look!

    The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

    Despite months of research, thousands of dollars poured into their gear, and countless hours dedicated to grinding away on the StairMaster, most hikers fall short of their goal.Why? They neglected to prepare for the most challenging element of a five month backpacking trip.While the PCT presents extraordinary physical challenges, it is the psychological and emotional struggles that drive people off the trail. Conquering these mental obstacles is the key to success. This groundbreaking book focuses on the most important and overlooked piece of equipment of all- the gear between one’s ears.Filled with first-hand, touching yet humorous vignettes and down-to-earth advice that both instructs and inspires, Pacific Crest Trials gives readers the mental road map they’ll need to hike from Mexico to Canada.Following up on his wildly popular guide to thru-hiking the Appalachian Trail in Appalachian Trials, Zach Davis has teamed up with 2015 PCT thru-hiker Carly Moree to bring readers the ultimate psychological and emotional guide to prepare for the Pacific Crest Trail.In Pacific Crest Trials readers will learn: Goal setting techniques that will assure hikers reach Canada The common early stage pitfalls and how to avoid them How to beat “the Death of the Honeymoon” The importance and meaning of “hiking your own hike” How to adapt amongst drastically different terrains, weather patterns, gear and logistical needs Five strategies for unwavering mental endurance How to save money on gear purchases Tips for enjoying rather than enduring each of the five million steps along the journey Advice for staving off post-trail depression from one of the country's most respected trail angels Nutritional guidance for avoiding post-trail weight gain Additionally, readers will receive an in-depth guide to choosing the right gear for their PCT thru-hike from Triple Crowner, Liz "Snorkel" Thomas.

Furthermore, Thomas offers several specific product recommendations, giving readers a helpful head start on their shopping list.Note: This is an adaptation of Appalachian Trials. Although this book is written with the Pacific Crest Trail thru-hiker in mind, the principles are largely similar.

    But our canine companions are in many ways our captives. No matter how cushy their captivity, we decide what and when they eat; where they sleep, poop, and play; when they can walk and when they must sit or stay. As the demand for dog trainers and veterinary behaviorists attests, dogs are not naturally adapted to living with and among modern humans. They give up a lot of freedom and instinctual pleasure, as well as their innate strategies for coping with stress and anxiety, in exchange for the comfort and care they get from humans. Bekoff and Pierce show that it is possible to let dogs be dogs without wreaking havoc on our own lives. They begin by illuminating the true nature of dogs and helping us "walk in their paws." They reveal what smell, taste, touch, sight, and hearing mean to dogs and then guide readers through everyday ways of enhancing a dog's freedom and minimizing deprivations in safe, mutually happy ways. The rewards, they show, are great -- for dog and human alike.
