Book excerpt: Excerpt from Cattle Gains and Plant Responses From Spring Grazing on Crested Wheatgrass in Northern New Mexico The only available research results that relate to grazing crested wheatgrass ln New Mexico are from fall grazing trials on Glorieta Mesa, near Pecos (reynolds and Springfield 2 Three years of grazing trials showed that daily gains of yearling cattle averaged 1. 1 pounds under the heaviest grazmg compared with pounds under moderate grazing for a month long fall season. Wide fluctuations 111 production from year to year were found at the Glorieta Mesa site. Conclusions based on these trials were to remove not more than 45 to 55 percent of the current year's growth during the early fall. Higher degrees of utilization at this time resulted in loss of plant vigor and decline in herbage production. Crested wheatgrass proved to be poorly adapted on this site, however, since nearly all plants inside protected plots as well as in the pastures died within a few years be cause of a combination of drought and gopher damage. Investigations in other regions have furnished information of value in interpreting results of the New Mexico experiments. One of the more comprehensive experiments on spring grazing of crested wheat grass was at Benmore, Utah (frischknecht et al. Results of the first 4 years of study showed that adult cattle gained and pounds a day under light (50 percent herbage removal), medium (65 percent), and heavy grazing (80 percent), respectively. Intensity of grazing likewise influenced daily calf gains, which were significantly less under heavy grazing. Heavy grazmg produced slightly more gain per acre than medium grazmg during the first 2 years, but this was reversed 1n the next 2 ye e.ars Stocking rates for 4 years averaged 3. 1 acres per cow-month for the light intensity, acres for the medium, and 1. 8 acres for the heavy. Light grazing allowed considerable old growth to accumulate on grass bunches, but utilization was more uni form and old growth did not accumulate under the medium and heavy grazing. Density of crested wheatgrass. Increased 54 percent on the average, and no difference due to grazing treatment was detected. Fewer young wheatgrass plants, however, became established under heavy grazing. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Invasive Species in Forests and Rangelands of the United States written by Therese M. Poland and published by Springer Nature. This book was released on 2021-02-01 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

Download or read book Geoecology of the Marias River Canyon Montana USA written by James G. Schmitt and published by Geological Society of America. This book was released on 2017-03-16 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Marias River canyon in north-central Montana served during late Holocene time as a locus of human activity in an ecologically and geologically dynamic landscape. This volume presents the results of interdisciplinary research, synergistically combining geologic, ecologic, and archaeologic approaches focused on examining the ways that Late Precontact peoples depended upon the animal (bison) and plant resources of a changing landscape subject to erosion and sediment transport as dominant surficial processes. Connections between erosion and deposition, plant community distribution, large mammal niches, and native peoples' place in the Marias River canyon geoecosystem, as well as the role of tributary-junction alluvial fans as repositories of archaeological materials and vertebrate faunal remains are emphasized.

Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Available in PDF, EPUB and Kindle. Book excerpt: Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Available in PDF, EPUB and Kindle. Book excerpt: "The Flora of Missouri project, directed by Garden Curator, Dr. George Yatskievych, is an ongoing effort to update and compile information on the state's flora. It began in 1987 as a joint effort of the Missouri Botanical Garden and the Missouri Department of Conservation. One of its main goals is a three-volume revision of former Missouri Botanical Garden curator Julian A. Steyermark's 'Flora of Missouri', first published in 1963. Missouri's ever changing plant diversity, the shifting distributions of its plant species, and the many new records of plants in the state have necessitated an expansion of Steyermark's original publication into three volumes."--
