Moreover, groundbreaking research on genes, and especially key families of genes such as the Homeobox genes which controlthe development of body plans, has led to radical changes in the classification of animals. In this Very Short Introduction, Peter Holland presents a cutting-edge tour of the animal kingdom, providing an authoritative summary of the modern view of animal life, its origins, and the new classificationresulting from DNA studies. Beginning with the definition of animals (not obvious in biological terms), Holland takes the reader through the revolutionary new high-level groupings of animals (phyla) based on evolutionary relationships and ancestry. Ranging from corals and sponges to nematodes, seasquirts, and vertebrates, and illuminating many key topics in zoology, this fascinating, brief overview will be of great value to all students of the life sciences as well as providing a concise summary for the interested lay reader.

    Chapters on the structure and ecology of tree bark, descriptions of bark appearance, an easy-to-use identification key, and supplemental information on non-bark characteristics—all enhanced by over 450 photographs, illustrations, and maps—will show you how to distinguish the textures, shapes, and colors of bark to recognize various tree species, and also understand why these traits evolved. Whether you’re a professional naturalist or a parent leading a family hike, Bark: A Field Guide to Trees of the Northeast is your essential guide to the region’s 67 native and naturalized tree species.

    Her fascinating and wide-ranging work provides clear explanations of the science surrounding keystone predators and considers how this notion can help provide practical solutions for restoring ecosystem health and functioning.Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs.At their most fundamental level, trophic cascades are powerful stories about ecosystem processes of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf’s Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.

    Veteran science writer Jon Luoma uncovers the inner workings of an ancient forest, from the microscopic bugs in the soil to the giant trees.

    She had no intention of staying long; she simply wanted to see if the rumors were true. That initial trip changed Smolker’s life; it commenced a fifteen-year scientific obsession that has culminated in this fascinating scientific adventure story–the first-ever intimate account of dolphin life in the wild.To Touch A Wild Dolphin is a seminal work that radically alters our fundamental understanding of these enigmatic creatures. Learning to identify scores of dolphins by their dorsal fin, Smolker and her team of scientists were able to conduct close and consistent studies that revealed the dolphin to be even more intelligent than we’d previously suspected. And while they were every bit as playful as we’ve known them to be, they also proved to have a dark and alarmingly violent side. But more than just a document on dolphins, this book is a touchingly personal look at the life of a scientist, at the rigors and sacrifices but also the wonders and joys of unending days in the field. Written with prose poetic and pristine, this book is nothing short of a landmark.

    Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.

    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.

    To Lee Goff and his fellow forensic entomologists, each body recovered at a crime scene is an ecosystem, a unique microenvironment colonized in succession by a diverse array of flies, beetles, mites, spiders, and other arthropods: some using the body to provision their young, some feeding directly on the tissues and by-products of decay, and still others preying on the scavengers.Using actual cases on which he has consulted, Goff shows how knowledge of these insects and their habits allows forensic entomologists to furnish investigators with crucial evidence about crimes. Even when a body has been reduced to a skeleton, insect evidence can often provide the only available estimate of the postmortem interval, or time elapsed since death, as well as clues to whether the body has been moved from the original crime scene, and whether drugs have contributed to the death.An experienced forensic investigator who regularly advises law enforcement agencies in the United States and abroad, Goff is uniquely qualified to tell the fascinating if unsettling story of the development and practice of forensic entomology.

    A young man is murdered for his prized pet fish. An Asian tycoon buys a single specimen for $150,000. Meanwhile, a pet detective chases smugglers through the streets of New York. Delving into an outlandish world of obsession, paranoia, and criminality, The Dragon Behind the Glass tells the story of a fish like none other. Treasured as a status symbol believed to bring good luck, the Asian arowana, or “dragon fish,” is a dramatic example of a modern paradox: the mass-produced endangered species. While hundreds of thousands are bred in captivity, the wild fish has become a near-mythical creature. From the South Bronx to Borneo and beyond, journalist Emily Voigt follows the trail of the arowana to learn its fate in nature. With a captivating blend of personal reporting, history, and science, Voigt traces our fascination with aquarium fish back to the era of exploration when intrepid naturalists stood on the cutting edge of modern science, discovering new species around the globe. In an age when freshwater fish now comprise one of the most rapidly vanishing groups of animals, she unearths a surprising truth behind the arowana’s rise to fame—one that calls into question how we protect the world’s rarest species. An elegant examination of the human conquest of nature, The Dragon Behind the Glass revels in the sheer wonder of life’s diversity and lays bare our deepest desire—to hold on to what is wild.

    Have you ever wondered if your dog might be a bit depressed? How about heartbroken or homesick? Animal Madness takes these questions seriously, exploring the topic of mental health and recovery in the animal kingdom and turning up lessons that Publishers Weekly calls “Illuminating…Braitman’s delightful balance of humor and poignancy brings each case of life….[Animal Madness’s] continuous dose of hope should prove medicinal for humans and animals alike.” Susan Orlean calls Animal Madness “a marvelous, smart, eloquent book—as much about human emotion as it is about animals and their inner lives.” It is “a gem…that can teach us much about the wildness of our own minds” (Psychology Today).

    Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression. Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity. Here, they present a revelatory understanding of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears--only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, all our primeval fears awaken again. The risk of an automobile accident on the way to bear country far outstrips the risk of a close-range encounter with a bear, but it's the bear that worries us as we hurtle down the pavement at a hundred kilometres an hour.In this timely and sensitive book, Kevin Van Tighem calls on decades of experience, knowledge and understanding in order to enlighten readers about our relationship with and attitude toward bears. Along the way we are confronted with the realities confronting these great animals as a result of our ever-expanding human population and their ever-shrinking natural habitat. Through historical research, field observation, practical advice, personal anecdotes and an array of stunning photos, Van Tighem has written a comprehensive book that is meant to demystify bears in order to promote a deeper understanding of these powerful yet vulnerable creatures.

    Highly intelligent and adaptable, they hunt and play together in close-knit packs, sometimes roaming over hundreds of square miles in search of food. Once teetering on the brink of extinction across much of the United States and Europe, wolves have made a tremendous comeback in recent years, thanks to legal protection, changing human attitudes, and efforts to reintroduce them to suitable habitats in North America.As wolf populations have rebounded, scientific studies of them have also flourished. But there hasn't been a systematic, comprehensive overview of wolf biology since 1970. In Wolves, many of the world's leading wolf experts provide state-of-the-art coverage of just about everything you could want to know about these fascinating creatures. Individual chapters cover wolf social ecology, behavior, communication, feeding habits and hunting techniques, population dynamics, physiology and pathology, molecular genetics, evolution and taxonomy, interactions with nonhuman animals such as bears and coyotes, reintroduction, interactions with humans, and conservation and recovery efforts. The book discusses both gray and red wolves in detail and includes information about wolves around the world, from the United States and Canada to Italy, Romania, Saudi Arabia, Israel, India, and Mongolia. Wolves is also extensively illustrated with black and white photos, line drawings, maps, and fifty color plates.Unrivalled in scope and comprehensiveness, Wolves will become the definitive resource on these extraordinary animals for scientists and amateurs alike. “An excellent compilation of current knowledge, with contributions from all the main players in wolf research. . . . It is designed for a wide readership, and certainly the language and style will appeal to both scientists and lucophiles alike. . . . This is an excellent summary of current knowledge and will remain the standard reference work for a long time to come.”—Stephen Harris, New Scientist “This is the place to find almost any fact you want about wolves.”—Stephen Mills, BBC Wildlife Magazine
