Download or read book Grassland Dynamics written by Alan K. Knapp and published by Oxford University Press on Demand. This book was released on 1998 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first volume in the Long-Term Ecological Research (LTER) Network Series. Established in 1980, the LTER program is exploring a wide variety of biomes characteristic of the United States and developing a baseline for ecosystem dynamics over long time periods and broad spatial scales. The volumes in this series will include both comprehensive reviews of research from particular sites and topical overviews which use data from many sites to examine important questions in ecology. This volume, which focuses on the Konza Prairie in northeastern Kansas, is a synthesis of over 15 years of research in pristine tallgrass prairie. It gives a comprehensive site description and summarizes the key long-term studies that form the basis for the Konza Prairie Long-Term Ecological Research Program. It then presents a synthesis of the many research areas involved and develops a foundation for future ecological studies in tallgrass prairie. With over 150 figures and tables, chapters that encompass microbial through landscape scales, and an emphasis on lessons learned from long-term studies, this volume provides a unique and comprehensive perspective on the structural and functional ecology of the grassland ecosystem that once covered most of central North America.

Download or read book Grassland Invertebrate Interactions Plant Productivity Resilience and Community Dynamics written by Ivan Hiltpold and published by Frontiers Media SA. This book was released on 2017-10-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural and anthropogenic grasslands such as prairies, meadows, rangelands, and pastures cover more than 40% of the planet’s surface and provide a wealth of ecological services. Grasslands alone store one third of the global carbon stocks and grass roots, through their specific architectures, ensure water cycling and prevent the erosion of fertile topsoil. In addition, grasslands are of vital importance for human food production as vast areas of rangelands and pastures provide feed for livestock. Pastoral legumes mobilize atmospheric nitrogen and improve fertility of arable soils. Not least, grasslands are an essential genetic resource. The three major crop species that feed half of the global population have been bred from wild grasses. Ancestors of our contemporary turf cultivars, common components of urban landscapes and recreation spaces, originated from wild grasslands. Although natural and managed grasslands represent pivotal ecosystems, many aspects of how they function are poorly understood. To date, most attention has focused on grassland primary producers (i.e. forage plants) and mammalian grazers but invertebrates are likely to play an equally, if not more important role in grassland ecosystem functioning. In Australian pastures, for example, the biomass of root-feeding scarab beetles can often exceed that of sheep and plant damage caused by invertebrates is sometimes equivalent to an average dairy cow’s grass consumption. Indeed, grasslands are one of the most densely populated ecosystems with invertebrates being probably the most important engineers that shape both plant communities and the grassland as a whole. In a rapidly changing world with increasing anthropogenic pressure on grasslands, this Research Topic focuses on: 1. How grassland habitats shape invertebrate biodiversity 2. Impacts of climate change on grassland-invertebrate interactions 3. Plant and invertebrate pest monitoring and management 4. Plant-mediated multitrophic interactions and biological control in grasslands 5. Land use and grassland invertebrates 6. Plant resistance to invertebrate pests Given the increasing demand for food and land for human habitation, unprecedented threats to grasslands are anticipated. Resilient to some extent, these key ecosystems need to be better comprehended to guarantee their sustainable management and ecosystem services.

Download or read book Grassland written by Walter F. Wedin and published by ASA-CSSA-SSSA. This book was released on 2009 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grassland: Quietness and Strength for a New American Agriculture takes on the task of increasing our awareness of the vital role grass and grassland plants have in ensuring a sustainable future for America. Geared toward agriculturists, students, the public, and policymakers, Grassland aims to inspire and provide the reader the foundation needed to move into the future. Three main sections * track the history of grassland farming, highlighting the voices of grassland advocates * examine the current roles that grassland plays throughout the United States * look at the benefits grass-based agriculture can provide when grass is treated as an essential resource As Wendell Berry so eloquently argues in the foreword to Grassland, True farmers have minds that are complex and responsible...They understand and honor their debts to nature. They understand and honor their obligations to neighbors and consumers...In the time that is coming, we are going to need many more such farmers than we have, and we will need them much sooner than we can expect to get them.We will get them only to the extent that young people come along who are willing to fit their farming to the nature of their farms and their home landscapes, and who recognize the paramount importance of grass and grazing animals to good farming everywhere. This book will help that happen.

Download or read book Grassland a global resource written by D.A. McGilloway and published by BRILL. This book was released on 2023-08-28 with total page 429 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."

This book was released on 2012-12-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the occasion of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder Crops (NVWV) agreed to organize an International Symposium on a topic related to intensive grass and fodder production systems. The theme selected was "Animal manure on grassland and fodder crops: Fertilizer or waste?" This Symposium was organized under the auspices of the European Grassland Federation and held at the International Agricultural Centre in Wageningen from 31 August to 3 September 1987. The problems connected with the disposal of animal waste have received much attention in recent years, especially in regions with intensive animal of animal manure per hectare agricul husbandry. Whereas the production tural land increased strongly, the need for it decreased because of the introduction of cheap inorganic fertilizers which are easier to handle and have a more reliable effect on crop growth. As a consequence, many farmers dispose of animal manure as cheaply as possible, whilst avoiding damage to grassland and crops and paying little attention to effective use of the plants nutrients contained in the manure. Present practices of manure handling and application often lead to environmental problems. The rise in awareness of these problems renewed interest in possibilities to improve the utilization of nutrients from animal manure in crop production. Research on this topic has been stimulated in many countries during the last decade and the aim of this Symposium was to review and assess present-day knowledge.
