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.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    He is as passionate about swamps, bogs, and vernal ponds and the creatures who live in them as most of us are about our families and closest friends. He knows frogs and snakes, muskrats and minks, dragonflies, water lilies, cattails, sedges--everything that swims, flies, trudges, slithers, or sinks its roots in wet places. In this "intimate and wise book" (Sue Hubbell), Carroll takes us on a lively, unforgettable yearlong journey, illustrated with his own elegant drawings, through the wetlands and reveals why they are so important to his life and ours -- and to all life on Earth.

    A concise atlas of anatomy, it contains more than 200 specially prepared accurate and clear drawings that include material never illustrated before. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird lovers in general, it discusses why birds look and act the way they do.Designed to supplement a basic ornithology textbook, the Manual of Ornithology covers systematics and evolution, topography, feathers and flight, the skeleton and musculature, and the digestive, circulatory, respiratory, excretory, reproductive, sensory, and nervous systems of birds, as well as field techniques for watching and studying birds. Each chapter concludes with a list of key references for the topic covered, with a comprehensive bibliography at the end of the volume. The book will be a guide and reference for every level of bird study—a basic tool for investigation for anyone curious about the fascinating world of birds.

    From the most desolate desert to the depths of the jungle, from blistering heat and freezing cold to perpetual darkness and deadly UV, discover how a whole host of creatures have adapted to life in the most extreme conditions. And how they compete with one another to become the largest, the fastest, the most poisonous, or most devious - all in a bid to survive.Planet Earth II includes the first in-depth look at the urban environment, and the surprising range of behaviours occurring right under our noses, as well as some previously untouched island worlds. Filmed with remarkable 5k and infra-red technology, these are the challenges, the confrontations, and the triumphs of some of the most extraordinary creatures in the natural world, told from their perspective.This is our planet, as you have never seen it before.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.

    By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season. Wood thrush, Kentucky warbler, the Eastern kingbird--migratory songbirds are disappearing at a frightening rate.
