This book was released on 2003 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 25 of Flora North America is one of two volumes on grasses to be published in this series. Together they will provide a comprehensive, authoritative, illustrated account of this important group of plants. Most of the species treated are either native to North America north of Mexico or are introduced species that are now established in the region, but there are many that do not fit into these categories. Among the additional species are several that the USDA has identified as major weed threats; and others that are known only as cultivated plants, some being cultivated for their ornamental value, others as sources for human food or animal forage. For instance, volume 25 includes such ecologically important species as Big and Little Bluestem, economically important species of Sorghum and Corn, ornamental species such as Job's Tears and Hakonechloa, and noxious weeds such as Itchgrass. The volume includes identification keys, descriptions, line drawings, and ecological characteristics for each of the species; distribution maps for the native and established species; and a list of the synonyms currently in use for the accepted names. The treatments, each of which has been extensively reviewed, are based on a combination of original observations and critical review of the literature.

Available in PDF, EPUB and Kindle. Book excerpt: Nutrients from farms in the Mississippi River Basin are the leading cause of the Gulf of Mexico‘s 'Dead Zone,' a 5,000 to 7,000 square mile region where declining oxygen levels are threatening the survival of marine life. From the Corn Belt to the Gulf explores how new agricultural policy can help alleviate this problem, and at the same time improve water quality overall, enhance biodiversity, improve the quality of life for the people who live and work in Corn Belt communities, and relieve downstream flooding. The themes of the book are the far-reaching environmental impacts of Corn Belt agriculture, including associated economic and social effects at multiple spatial scales - and the potential for future agricultural policy to address those impacts through changes in agricultural landscapes and practices. We know that the environmental 'footprint' of Corn Belt agriculture extends beyond farmland and adjacent lakes and streams to groundwater, rivers, cities downstream, into the Gulf of Mexico, and, ultimately, to global oceanic and atmospheric systems. And we acknowledge that agricultural policies, including commodity support payments, have economic impacts at the national and international levels. Pressing negotiations with America‘s trade partners, along with increasing societal attention to both the costs and environmental effects of current agricultural policy, are creating momentum for policy change. From the Corn Belt to the Gulf presents innovative, integrated assessments of the agriculture and ecological systems in the Mississippi River Basin along with studies of local Iowa agricultural watersheds. Contributors from multiple academic and professional disciplines discuss how agricultural policies have contributed to current environmental conditions, and, in what the authors term 'alternative futures' for agricultural landscapes, envision how new policy can help achieve more beneficial patterns.

Available in PDF, EPUB and Kindle. Book excerpt: Anyone who works with the vascular plants of Iowa—researchers, conservationists, teachers, agricultural specialists, horticulturists, gardeners, and so on—and those who are simply interested in knowing more about the state's plants have long felt a need for a comprehensive flora of Iowa. This meticulously researched volume is a giant first step toward such a flora. This book consists of an extended essay on the natural history of the vascular plants of Iowa, a discussion of their origins, a description of the state's natural regions, and a painstakingly annotated checklist of Iowa vascular plants. The data, which apply to over 150 years, took more than 15 years to collect. All known vascular plants that grow and persist in Iowa without cultivation are included in the checklist. These are native plants, primarily, but a large number of introduced species have become established throughout the state. Also included are Iowa's major crop plants and some of its common garden plants. The lengthy checklist provides an accurate and up-to-date listing of species names and common names, synonyms, distribution, habitat, abundance, and origin; county names are given for very rare species, and the most complete information has been provided for all rare plants and troublesome species. The wealth of information is this well-organized, practical volume—which describes more than two thousand species from Adiantum pedatum, the northern maidenhair fern of moist woods and rocky slopes, to Zannichellia palustris, the horned pondweed of shallow marshes and coldwater streams—makes it possible to identify Iowa plants correctly. All midwesterners will want to own a copy of The Vascular Plants of Iowa.
