Download or read book The Ecology of Cyanobacteria written by B.A. Whitton and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacteria make a major contribution to world photosynthesis and nitrogen fixation, but are also notorious for causing nuisances such as dense and often toxic `blooms' in lakes and the ocean. The Ecology of Cyanobacteria: Their Diversity in Time and Space is the first book to focus solely on ecological aspects of these organisms. Its twenty-two chapters are written by some thirty authors, who are leading experts in their particular subject. The book begins with an overview of the cyanobacteria - or blue-green algae, for those who are not specialists - then looks at their diversity in the geological record and goes on to describe their ecology in present environments where they play important roles. Why is one of the key groups of organisms in the Precambrian still one of the most important groups of phototrophs today? The importance of ecological information for rational management and exploitation of these organisms for commercial and other practical purposes is also assessed. Accounts are provided of nuisances as well as the ecology of the commercially successful Spirulina and the role of cyanobacteria in ecosystem recovery from oil pollution. Many chapters include aspects of physiology, biochemistry, geochemistry and molecular biology where these help general understanding of the subject. In addition there are three chapters dealing specifically with molecular ecology. Thirty-two pages of colour photos incorporate about seventy views and light micrographs. These features make the book valuable to a wide readership, including biologists, microbiologists, geologists, water managers and environmental consultants. The book complements the highly successful The Molecular Biology of Cyanobacteria already published by Kluwer.

This book was released on 1995-09-30 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers the various aspects of the use of pesticides, their behavior, degradation, and impacts in wetland ricefields, and presents the results of surveys conducted in the Philippines and Thailand. It includes both bibliographic reviews and selected aspects of the experimental results of a research project on pesticide impacts in wetland ricefields. The first phase of the `Pesticide Impact' project was developed in the Philippines from 1989 to 1991. It was a multidisciplinary/collaborative approach involving scientists from IRRI, NRI (England), ORSTOM (France), UPLB (Philippines) who studied the effects of pesticides on the environment and on farmers' health, and the economical aspects of their use.

This book was released on 2013-03-09 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical fertilizers have had a significant impact on food production in the recent past, and are today an indispensable part of modern agriculture. On the other hand, the oil crisis of the 1970s and the current Middle East problems are constant reminders of the vulnerability of our fossil fuel dependent agriculture. There are vast areas of the developing world where N fertilizers are neither available nor affordable and, in most of these countries, balance of payment problems have resulted in the removal of N fertilizer subsidies. The external costs of environmental degradation and human health far exceed economic concerns. Input efficiency of N fertilizer is one of the lowest and, in turn, contributes substantially to environmental pollution. Nitrate in ground and surface waters and the threat to the stability of the ozone layer from gaseous oxides of nitrogen are major health and environmental concerns. The removal of large quantities of crop produce from the land also depletes soil of its native N reserves. Another concern is the decline in crop yields under continuous use of N fertilizers. These economic, environmental and production considerations dictate that biological alternatives which can augment, and in some cases replace, N fertilizers must be exploited. Long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. The process of biological nitrogen fixation offers and economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources. In this book, we outline sustainability issues that dictate an increased use of biological nitrogen fixation and the constraints on its optimal use in agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains selected papers presented at the International Symposium on 'Economics of Eco system Management' held in Halkidiki, Greece from 26 to 30 September 1983. The meeting was designed to consider as much as possible the interaction between the economy and ecology, and in parallel to provide a forum for the presentation of the ecological and developmental initiatives of the Ministry of Youth of Greece. As chairman of the organizing committee I want to express our thanks to OECD, EEC and UNESCO for sponsoring the Symposium. From Greece the Ministries of Culture and Environment are gratefully acknowl edged. Last but not least, I want to express our sincere thanks for the continuous support to the Ministry of Youth and Sports of Greece, and especially to the Minister Mr. Kostas Laliotis because he not only adopted the idea for sponsoring events like this, but also because of his interest which became obvious with his presence and talk during the meeting. The staff of the Ecology Division, namely Drs. M. Arianoutsou and D. Vokou, Messrs. J. Pandis, Th.A. Mardiris, S. Paraskevopoulos and Miss A. Papagianni provided great help concerning the organization, as well as Mrs. A. Karamanli-Vlahopoulou, my secretary, who is always behind these events. N.S. Margaris Contents Preface by N. S.

Available in PDF, EPUB and Kindle. Book excerpt: Rice based cropping system is the major cropping system practised in India which includes the rotation of crops involving rice, pulses, oil seeds, cotton, sugar cane, green manures etc., The rice based cropping system offers lot of scope for the effective utilization of a wide range of biofertilizers such as Azolla, BGA, Azospirillum, Rhizobium Gluconacetobacter diazotrophicus and other heterotrophic N2 fixing bacteria which help to increase the yield by reducing the cost of cultivation. It thus has dual advantages of being sustainable without endangering the environment and being highly cost effective. This book ‘Biofertilizer Technology for Rice Based Cropping System’ deals with the current developments in the basic and applied aspects of biofertilizers used in the rice based cropping including the novel endophytic diazotrophs viz., Azorhizobium caulinodans, Gluconacetobacter diazotrophicus, Pink Pigmented Facultative Methylotrophs (PPFM) etc. The role of P, Zn and Si solubilizers in the nutrient dynamics of the rice ecosystem has also been covered. The strategies for production and distribution of quality inoculants for rice based cropping system has been given due importance with a focus on the molecular approaches for rapid and reliable quality control of biofertilizers. This book can be considered as a monograph on the usage of biofertilizers in rice based cropping system. It will be very useful for the scientists, researchers, students and extension workers involved in the management of crops in rice based cropping system .

This book was released on 2013-04-09 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers. Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production. This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.
