Book Synopsis Digestive Physiology and Metabolism in Ruminants by : Y. Ruckebusch
Download or read book Digestive Physiology and Metabolism in Ruminants written by Y. Ruckebusch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.
Book Synopsis Microfloral and faunal interactions in natural and agro-ecosystems by : M.J. Mitchell
Download or read book Microfloral and faunal interactions in natural and agro-ecosystems written by M.J. Mitchell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: MYRON J. MITCHELL* The biota of soils constitute an integral part of both natural and agronomic ecosystems. The soil microflora and fauna in conjunction with the belowground portion of the Metaphyta or higher plants constitute the living milieu, components of which are in intimate association with each other as well as the abiotic constituents of the soil. Since these associations or interactions are important in regulat ing both the flux and availability of energy and nutrients, the central theme of the present book focuses on these interactions. The effects of microfloral and faunal inter actions with regard to overall ecosystem dynamics and specific critical processes will be examined. HISTORICAL ASPECTS The coverage of this volume is an extension of a vast body of literature which dates back to the 18th century. A brief compendium of major books and reviews published from 1960 to 1983 is given chronologically in Tables 1 and 2, respectively. Russell (1961) has reviewed work in the 1800's during which some of the basic tenets on the relationships between plant nutrition and soil properties became estab lished. In this period agricultural science was founded and the study of soil bacteriology began. The evolution of soil biology up to the early 1970's has been described by Satch211 in the volume edited by Dickinson and Pugh (1974). *Department of Environmental and Forest Biology, SUNY, College of Environmental Science and Forestry, Syracuse, NY 13210 2 ~ .

Book Synopsis Environment, Climate, Plant and Vegetation Growth by : Shah Fahad
Download or read book Environment, Climate, Plant and Vegetation Growth written by Shah Fahad and published by Springer Nature. This book was released on 2020-10-05 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date account of the current understanding of climate change and global warming related to environment, climate, plant and vegetation growth. The aim of this book is to provide a platform for scientists and academics world-wide to promote, share, and discuss various new issues and developments in the area of plant and vegetation growth related to climate change. Over the next decades, it is predicted that billions of people, particularly those in developing countries, face shortages of water and food and greater risks to health and life as a result of climate change. Concerted global action is needed to enable developing countries to adapt to the effects of climate change that are happening now and will worsen in the future. The book will also enhance the understanding on issues related to climate change, giving a clear indication of a looming global warming crisis. Addressing global climate change is a monumental battle that can only be fought by the leaders of tomorrow, but future leaders are molded through education and shaped by the leaders of today.
Book Synopsis Grassland Productivity and Ecosystem Services by : Gilles Lemaire
Download or read book Grassland Productivity and Ecosystem Services written by Gilles Lemaire and published by CABI. This book was released on 2011 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.
