Ants of North America
Author: Brian L. Fisher
Publisher: Univ of California Press
ISBN: 0520254228
Category : Nature
Languages : en
Pages : 211
Book Description
"In this enormously useful book, a profound need is met by a profound contribution, the first such comprehensive work in over fifty years. While brief, Ants of North America is the distillation of a vast amount of study and practice. It is a joy to browse and read, and will have an important impact on the study of ants."—Edward O. Wilson, University Research Professor Emeritus, Harvard University "Two of the most prolific ant faunists have produced a marvelous taxonomic guide to the ant genera of North America. The keys and genus descriptions are succinct and easy to read, the illustrations superb. This book is a must for entomologists, ecologists, and particularly all who study ants."—Bert Hölldobler, Foundation Professor of Life Sciences, Arizona State University "This book represents a bold advance in the study of North American ants. It provides, for the first time, an accessible and lavishly illustrated guide to all the ant genera occurring in the United States and Canada. It will greatly enhance both public interest in ants and scientific investigation of their ecology, behavior and evolution."—Philip S. Ward, Department of Entomology and Center for Population Biology, University of California at Davis

Status of Pollinators in North America
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309102898
Category : Technology & Engineering
Languages : en
Pages : 327
Book Description
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
