Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Download or read book Microbial Control of Weeds written by D.O. TeBeest and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is appropriate at this time to reflect on two decades of research in biological control of weeds with fungal plant pathogens. Some remarkable events have occurred in the last 20 years that represent a flurry of activity far beyond what could reasonably have been predicted. In 1969 a special topics review article by C. L. Wilson was published in Annual Reviews of Phytopathology that examined the literature and the potential for biological control of weeds with plant pathogens. In that same year, experiments were conducted in Arkansas that determined whether a fungal plant pathogen could reduce the infestation of a single weed species in rice fields. In Florida a project was under way to determine the potential use of a soil-borne plant pathogen as a means for controlling a single weed species in citrus groves. Work in Australia was published that described experiments that sought to determine whether a pathogen could safely and deliberately be imported and released into a country to control a weed of agricultural importance. All three projects were successful in the sense that Puccinia chondrillina was released into Australia to control rush skeleton weed and was released later into the United States as well, and that Colletotrichum gloeosporioides f.sp. aeschynomene and Phytophthora palmivora were later both marketed for the specific purpose of controlling specific weed species.

Download or read book Animal Agriculture written by Fuller W. Bazer and published by Academic Press. This book was released on 2019-10-25 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management Addresses the urgent issue of sustainability in modern animal agriculture Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
Download or read book Grassland written by D. A. McGilloway and published by Brill Wageningen Academic. This book was released on 2005 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The concept of grasslands as a global resource is not new. Indeed many recognised authorities have been canvassing for a global approach to understanding, managing and exploiting this resource for many years. This is the first book that gathers together leading experts from around the world to outline our current understanding of this complex ecosystem, the ways in which it can be enhanced and utilised and where the research challenges are for the future. The following themes unite the book: - Efficient production from grassland; - Grassland and the environment; - Delivering the benefits from grassland. The reader is given an in depth understanding of the biology of the system and how grasslands are crucial for soil stabilisation and water quality. Secondly, much attention is given to how grasslands offer the possibility of increasing food supply and income generation, which is a hugely important but often ignored facet in today's climate of extensification and biodiversity. Current advances in the grassland sciences have a proven potential to promote the economic development and environmental stability of regions, nations and peoples, particularly in some of the most resource-limited areas of the world. Approaches for achieving the most effective development and adoption of new technology are reviewed."
