Identify and understand the plants that are changing the North American landscape forever.
From the New York Times-bestselling author, Roland Smith, comes a fascinating, fact-filled resource that explores how humans have introduced—on purpose and by accident—plants and animals to parts of the world where they were previously unknown. . .sometimes with disastrous results. Did you know that brown rats were brought to the United States in the eighteenth century on a ship from England? Or that thousands of exotic pets were released into the Florida Everglades after a hurricane in 1992, leading to today’s booming Burmese python population? All over the country, non-native species from around the world have been introduced to our lands, irrevocably changing the natural balances of their new habitats. This is the story of some of those newcomers, but also of human error and nature gone wild. By looking at thirty different intrusive plants and animals, They Are Here! explores invasive species, their impact on our environment, and the steps we can take to support local ecosystems under threat.
This extensively color-illustrated atlas serves as a comprehensive guide not only to persons actively involved in food quality control but also to students and trainees, as well as to nontechnical food in-dustry personnel who wish to enhance their product knowledge. Each chapter is devoted to a commodity group (e.g., fresh meats) with two non-commodity chapters concerned with precepts of food quality control and foreign bodies and infestations. Those foods similar in nature and which could be placed in more than one chapter are cross-referenced. Extensively Illustrated Illustrations were selected based on those quality defects most commonly encountered at retail or final inspection level, to...
Identifies two hundred of the most common invasive plants, including bog plants, herbaceous perennials, and shrubs, and offers guidance on selecting the safest and most responsible eradication options.
Invasive Plants of the Upper Midwest is an informative, colorful, comprehensive guide to invasive species that are currently endangering native habitats in the region. It will be an essential resource for land managers, nature lovers, property owners, farmers, landscapers, educators, botanists, foresters, and gardeners. Invasive plants are a growing threat to ecosystems everywhere. Often originating in distant climes, they spread to woodlands, wetlands, prairies, roadsides, and backyards that lack the biological controls which kept these plant populations in check in their homelands. Invasive Plants of the Upper Midwest includes more than 250 color photos that will help anyone identify probl...
Na s. tyt.: "This book is dedicated to Judith D. Zuk, president emeritus of Brooklyn Botanic Garden, whose leadership made the Garden's pioneering books on invasive plants possible".
Approximately 70% of the world's population lives in coastal areas, and the majority of these people depend on coastal aquifers for freshwater. The fragility of these aquifers and their sensitivity to human activity demand informed, competent management to guarantee their survival. Significant knowledge and new technologies related to the subject h
The study of human diet brings together reseachers from diverse backgrounds ranging from modern human nutrition and biochemistry to the geochemistry of fossilized bones and teeth. The contributions to this volume grow out of the Fourth Advanced Seminar on Paleodiet and provide a forum for scholars with common interests to discuss the latest advances and interpretations and chart future directions for paleodietry research.
Hunt tests are noncompetitive testing programs where each retriever entered is judged against a written standard and passes or fails the test on his own merits. Compared with competitive events, the atmosphere at hunt tests is refreshing. Writing for hunt testers at every level, Spencer fills in the things they forgot to tell you. Whether you are beginner, a skilled handler needing an occasional refresher, a judge or a workerthis book is for you!
Invasive species are everywhere, from forests and prairies to mountaintops and river mouths. Their rampant nature and sheer numbers appear to overtake fragile native species and forever change the ecosystems that they depend on. Concerns that invasive species represent significant threats to global biodiversity and ecological integrity permeate conversations from schoolrooms to board rooms, and concerned citizens grapple with how to rapidly and efficiently manage their populations. These worries have culminated in an ongoing “war on invasive species,” where the arsenal is stocked with bulldozers, chainsaws, and herbicides put to the task of their immediate eradication. In Hawaii, mangrov...
