Download or read book Abiotic Stresses in Agroecology A Challenge for Whole Plant Physiology written by Mauro Centritto and published by Frontiers Media SA. This book was released on 2017-07-04 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry. Besides increasing carbon dioxide concentration and rising global temperature, increasingly frequent and severe climatic events (e.g. extended droughts, heat waves, flooding) are expected in the coming decades. Additionally, pollution (e.g. heavy metals, gaseous pollutants such as ozone or sulfur dioxide) is an important factor in many regions, decreasing plant productivity and product quality. This Research topic focuses on stress responses at the level of whole plants, addressing biomass-related processes (development of the root system, root respiration/fermentation, leaf expansion, stomatal regulation, photosynthetic capacity, leaf senescence, yield) and interactions between organs (transport via xylem and phloem, long-distance signaling and secondary metabolites). Comparisons between species and between varieties of the same species are helpful to evaluate the potential for species selection and genetic improvement. This research topic is focused on the following abiotic stresses and interactions between them: - Increased carbon dioxide concentration in ambient air is an important parameter influenced by global change and affects photosynthesis, stomatal regulation, plant growth and finally yield. - Elevated temperature: both the steady rise in average temperature and extreme events of shorter duration (heat waves) must be considered in the context of alterations in carbon balance through increased photorespiration, decreased Rubisco activation and carboxylation efficiency, damage to photosynthetic apparatus, as well as loss of water via transpiration and stomatal sensitivity. - Low temperatures (late frosts, prolonged cold phases, freezing temperature) can decrease overwintering survival rates, productivity of crop plants and species composition in meadows. - Water availability: More frequent, severe and extended drought periods have been predicted by climate change models. The timing and duration of a drought period is crucial to determining plant responses, particularly if the drought event coincides with an increase in temperature. Drought causes stomatal closure, decreasing the cooling potential of transpiration and potentially leading to thermal stress as leaf temperature rises. Waterlogging may become also more relevant during the next decades and is especially important for seedlings and young plants. It is not the presence of water itself that causes the stress, but the exclusion of oxygen from the soil which causes a decrease in respiration and an increase in fermentation rates followed by a period of potential oxidative stress as water recedes. - Salinity: high salt concentration in soil influences soil water potential, the water status of the plant and hence affects productivity. Salt tolerance will become an important trait driven by increased competition for land and the need to exploit marginal lands.Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry.

Download or read book Cattle in Ancient and Modern Ireland written by Fergus Kelly and published by Cambridge Scholars Publishing. This book was released on 2016-04-26 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cattle have been the mainstay of Irish farming since the Neolithic began in Ireland almost 6000 years ago. Cattle, and especially cows, have been important in the life experiences of most Irish people, directly and/or through legends such as the Táin Bó Cuailnge (The Cattle-raid of Cooley). In this book, diverse aspects of cattle in Ireland, from the circumstances of their first introduction to recent and ongoing developments in the management of grasslands – still the main food-source for cattle in Ireland – are explored in thirteen essays written by experts. New information is presented, and several aspects relating to cattle husbandry and the interactions of cattle and people that have hitherto received little or no attention are discussed.

Download or read book Forage in Ruminant Nutrition written by Dennis Minson and published by Elsevier. This book was released on 2012-12-02 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forage in Ruminant Nutrition is the 12th text in a series of books about animal feeing and nutrition. The series is intended to keep readers updated on the developments occurring in these fields. As it is apparent that ruminant animals are important throughout the world because of the meat and milk they produce, knowledge about the feeds available to ruminants must also be considered for increased production and efficiency. This text provides information that readers will find considerably invaluable about forage feeds, such as grass, legumes, hay, and straw. The book is composed of 16 chapters that feature the following concepts of ruminant forage feeding: • composition of ruminant products and the nutrients required for maintenance and reproduction; • energy and nutrient available in forage: calcium, phosphorus, magnesium, sodium, copper, iodine, zinc, manganese, selenium, and cobalt; • intake of forage by housed ruminants; • grazing; • forage digestibility; • protein in ruminant nutrition; • protein and other nutrient deficiencies. This volume will be an invaluable reference for students and professionals in agricultural chemistry and grassland and animal husbandry researches.
