Book excerpt: Bromus tectorum L., known as cheatgrass or downy brome, is arguably the most damaging invasive species in North America. Bromus tectorum reduces crop yields, increases the frequency of wildfires, and displaces indigenous species in North America, especially the intermountain west. The broad scale of damage to ecosystems and reductions in crop yields caused by B. tectorum necessitate action to mitigate ecosystem destruction and food shortages, and thus the on society. As a near obligate self-fertilizing species, B. tectorum has a life cycle uniquely adapted to the intermountain western United States. To adapt to natural ecosystems and cropping systems B. tectorum relies on variation in phenology traits and herbicide resistance. However, the source, maintenance, and impact, of the variation in phenology and herbicide resistance remains uncharacterized in B. tectorum. Using B. tectorum from the germplasm resource information network, the inland Pacific Northwest and Montana, we observed repeatable variation in phenology across the global accessions, between regions in North America and between genotypes sampled within the same location. A genome wide association study identified quantitative trait loci (QTL) controlling height and phenology traits, revealing punitive candidate genes underlying the variation in phenology traits. However, a genome wide scan for genomic indicators of selection revealed multiple putative candidate genes from the ATP-binding cassette transporter, cytochrome P450, glutathione s-transferase, and glycosyltransferase gene families implicated in non-target site resistance, but only one gene implicated with phenology. Identifying non-target site resistance genes under selection and not phenology genes, implies that herbicide resistance is a greater driver of selection for B. tectorum, in the invasive range. Using stochastic forward genetic simulations we identified migration and selection as key factors to maintain the genetic and phenotypic variation present in B. tectorum. Individual-based simulations revealed that marginal environments, where annual plants have a low fecundity, outcrossing does not confer an advantage to adaptation. Developing novel management strategies for B. tectorum by should be based on both the genetic and phenotypic variation present in B. tectorum and the theoretical basis for maintenance of the variation observed.

Download or read book Cheatgrass written by James A. Young and published by University of Nevada Press. This book was released on 2009-03-28 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cheatgrass (Bromus tectorum) is an exotic species that appeared in North America in the late nineteenth century and has since become a dominant plant in the arid and semiarid rangelands between the Sierra Nevadas, Cascades, and Rocky Mountains. It is the first grass to appear after the region's long, cold winters and thus has become an important forage plant for livestock and wildlife. Cheatgrass is also a major environmental hazard in the sagebrush plant communities where it has established itself, providing highly combustible fuel for the wildfires that have ravaged so much of the Great Basin since the mid-twentieth century. Cheatgrass is the first comprehensive study of this highly invasive plant that has changed the ecology of millions of acres of western rangeland. Authors Young and Clements have researched the biology and impact of cheatgrass for four decades. Their book addresses the subject from several perspectives: the history of the invasion; the origins and biology of cheatgrass; its genetic variations, breeding systems, and patterns of distribution; its impact on grazing management; and the role it plays, both positive and negative, in the lives of high desert wildlife.
Download or read book The Cheating Game written by Terry Azzouz MA LPC LSOTP and published by AuthorHouse. This book was released on 2010-10-20 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cheating Game is a book that addresses the issue of infidelity and adultery. Many people know the signs of cheating behaviors but few know the reasons their spouses cheat on them. Some think the only reason people cheat is because of sex. This is not true. The behavior might be sexual but the motives can range from revenge to the need for emotional connection. The Cheating Game not only addresses the signs and reasons people cheat, but it also offers solutions. Some of these solutions come in the form of knowing how to please your mate and how to be pleased as a woman. Other options to stopping the cheating game are explored including open relationships. The Cheating Game is written allowing all individuals to identify with the desire to save their relationship. Honesty is stressed along with open communication. While reading The Cheating Game, you will see yourself in the various examples. This book will make you want to take positive steps towards growth as a person and as a couple. It will be a revelation that transforms your life.

Download or read book Weeds written by Evelyn I. Funda and published by U of Nebraska Press. This book was released on 2013-09-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Thomas Jefferson’s day, 90 percent of the population worked on family farms. Today, in a world dominated by agribusiness, less than 1 percent of Americans claim farm-related occupations. What was lost along the way is something that Evelyn I. Funda experienced firsthand when, in 2001, her parents sold the last parcel of the farm they had worked since they married in 1957. Against that landscape of loss, Funda explores her family’s three-generation farming experience in southern Idaho, where her Czech immigrant family spent their lives turning a patch of sagebrush into crop land. The story of Funda’s family unfolds within the larger context of our country’s rich immigrant history, western culture, and farming as a science and an art. Situated at the crossroads of American farming, Weeds: A Farm Daughter’s Lament offers a clear view of the nature, the cost, and the transformation of the American West. Part cultural history, part memoir, and part elegy, the book reminds us that in losing our attachment to the land we also lose some of our humanity and something at the very heart of our identity as a nation.

Available in PDF, EPUB and Kindle. Book excerpt: Annual weeds continue to expand throughout the West eliminating many desirable species and plant communities. Wildfires are now common on lands infested with annual weeds, causing a loss of wildlife habitat and other natural resources. Measures can be used to reduce burning and restore native plant communities, but restoration is difficult and costly.
Download or read book Ecology of Desert Systems written by Walter G. Whitford and published by Academic Press. This book was released on 2019-08-20 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. - Highlights the complexity of global desert systems in a clear, concise way - Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change - Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems
