    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.

    With meticulous illustrations and detailed descriptions of plants and animals found in every corner of the continent, this newly updated and revised edition is the perfect companion in the field and a storehouse of information for the armchair naturalist or student.

    Rapoport, MD, author of The Boy Who Couldn’t Stop Washing) of treating animals with all-too-human problems in this “fascinating read for anyone who wants to know how the animal mind works” (Stanley Coren, author of The Intelligence of Dogs).Internationally renowned veterinarian Dr. Nicholas Dodman breaks new ground with the practice of One Medicine, the profound recognition that humans’ and other animals’ minds and emotions work in similar ways. Racehorses with Tourette’s Syndrome, spinning dogs with epilepsy, cats with Obsessive Compulsive Disorder, feather-plucking parrots with anxiety, and a diffident Bull Terrier with autism—these astonishing cases were all helped by One Medicine. Traditional treatments did not cure the behaviors because they treated the symptoms as disorders of the body, rather than problems of the mind. “This book itself is powerful medicine,” writes Sy Montgomery, author of The Soul of an Octopus. “Compelling…Dodman injects empathy into a world where sympathy previously reigned,” praised Publishers Weekly. “With much charm and compassion” (Susan Richards, author of Chosen by a Horse), Pets on the Couch raises our understanding of our pets’ complex interior lives and mental abilities, leading to a greater appreciation of them and the bonds we share.

    Fish and Wildlife Service. In August 1992, she accepted an assignment that forever changed--and endangered--her life. She posed as a big-game hunter in Alaska in order to infiltrate an international ring of poachers out to kill the biggest and best of that state's wildlife.A Hunt for Justice recounts her dramatic story--a story she was not legally permitted to write about until her retirement in 2004.

    Did you know that the peacock mantis shrimp has the most powerful punch on Earth? That vampire spiders are attracted to your smelly socks?

From the mother-eating black-lace weaver spiders to Texas horned lizards that can shoot jets of poisonous blood from their eyes, this book from fearless science blogger Becky Crew will introduce you to a menagerie of the world’s weirdest animals.

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    The more than 1,200 color photographs and two dozen line drawings include numerous exceptionally striking images. The giant silk moths, tiger moths, and many other species covered include forest pests, common garden guests, economically important species, and of course, the Mescal Worm and Mexican Jumping Bean caterpillars. Full-page species accounts cover almost 400 species, with up to six images per species including an image of the adult plus succinct text with information on distribution, seasonal activity, foodplants, and life history. These accounts are generously complemented with additional images of earlier instars, closely related species, noteworthy behaviors, and other intriguing aspects of caterpillar biology.Many caterpillars are illustrated here for the first time. Dozens of new foodplant records are presented and erroneous records are corrected. The book provides considerable information on the distribution, biology, and taxonomy of caterpillars beyond that available in other popular works on Eastern butterflies and moths. The introductory chapter covers caterpillar structure, life cycles, rearing, natural enemies, photography, and conservation. The section titled Caterpillar Projects will be of special interest to educators.Given the dearth of accessible guides on the identification and natural history of caterpillars, Caterpillars of Eastern North America is a must for entomologists and museum curators, forest managers, conservation biologists and others who seek a compact, easy-to-use guide to the caterpillars of this vast region.

    If animals could talk, we would ask them to recall their own ancestries, in particular the secrets as to how they avoided almost inevitable annihilation in the face of daily assaults by predators, climactic cataclysms, deadly infections and innate diseases.In Tears of the Cheetah, medical geneticist and conservationist Stephen J. O'Brien narrates fast-moving science adventure stories that explore the mysteries of survival among the earth's most endangered and beloved wildlife. Here we uncover the secret histories of exotic species such as Indonesian orangutans, humpback whales, and the imperiled cheetah-the world's fastest animal which nonetheless cannot escape its own genetic weaknesses.Among these genetic detective stories we also discover how the Serengeti lions have lived with FIV (the feline version of HIV), where giant pandas really come from, how bold genetic action pulled the Florida panther from the edge of extinction, how the survivors of the medieval Black Death passed on a genetic gift to their descendents, and how mapping the genome of the domestic cat solved a murder case in Canada.With each riveting account of animal resilience and adaptation, a remarkable parallel in human medicine is drawn, adding yet another rationale for species conservation-mining their genomes for cures to our own fatal diseases. Tears of the Cheetah offers a fascinating glimpse of the insight gained when geneticists venutre into the wild.

    The experience changed his life. While spending thousands of hours with the cubs, Kilham discovered unknown facets of bear behavior that have radically revised our understanding of animal behavior. Now widely recognized for his contributions to wildlife science, Kilham reveals that bears are altruistic and cooperate with unrelated, even unknown individuals, while our closer relatives, the supposedly more highly evolved chimps, cooperate only within troops of recognizable members. Beyond the natural history, he introduces individual bears who become enthralling and memorable characters.

    Tom Brown was taught the ancient skills of survival by a Native American he called Grandfather. His most advanced lessons were those of the scouts, members of a secret society who were highly attuned to nature. The scouts refined tracking to a disciplined science and art form. With these physical skills came enhanced perception and true enlightment. "Tracking was their doorway to the universe," Tom Brown writes, "where they could know all things through the tracks..."Now Tom Brown, Jr. shares generations of wisdom through one of the most rewarding pursuits to be found in nature. Tracking lets us unlock the secrets of each animal we follow, and in turn, to become more aware of our own place in nature and the world. It is a journey of discovery that engages the senses, awakens the spirit, and enlightens the soul.

    This guide shows how to recognize hawks the way we recognize friends at a distance: by body shape, movements, and locale.

    She introduces you to an African gray parrot named Alex, a bonobo named Kanzi, and a border collie named Betsy. Each of these animals tells us something interesting about the way they perceive and manipulate their world. The article also looks at what scientists are learning about the intelligence of dolphins and crows, beyond mere communication.   In “Almost Human,” Mary Roach takes us to the savannahs of Senegal to meet a group of 34 chimpanzees, whose behavior and social structures have given scientists some important clues about the nature of their communication and intelligence.   In “The Genius of Swarms,” Peter Miller looks at the collective behavior of ants, bees, and other insects for what they can tell us about social organization and how sometimes intelligence lies outside of the individual brain. This article served as the basis for his book, The Smart Swarm: How Understanding Flocks, Schools, and Colonies Can Make Us Better at Communicating, Decision Making, and Getting Things Done.
