Download or read book Systems Analysis in Ecology written by Kenneth E. F. Watt and published by Elsevier. This book was released on 2013-10-22 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems Analysis in Ecology surveys the problems and techniques of systems analysis in ecology. The opening and closing chapters were written by the editor, the first to explain why systems analysis is needed in ecology and what is meant by the term, and the last to point out the implications of this new approach for the future development of ecology. The book opens with a discussion of the nature of systems analysis. This is followed by separate chapters on the complexity of ecological systems and problems in their study and management; the organization and analytical procedures required by a large ecological systems study; telemetry and automatic data acquisition systems; and surveillance of the activities of small mammals. Subsequent chapters deal with the analysis of bird navigation experiments; the analysis of determination in population systems; building models of complex ecological systems; mathematical tools for the design of better salmon fishery management systems; and the evolution of ecological research programs.

Available in PDF, EPUB and Kindle. Book excerpt: Leading authorities from wide geographical regions of the globe will review the most up-to-date information in relation to temperate grasslands. Topics covered are: nutritive value of pasture; plant characteristics conducive to high animal intake and performance; modelling of both grass growth and animal production and intake in grazing systems; optimising financial returns from grazing; decision support systems; optimal animal breeds and traits for grazing systems; challenges and opportunities for animal production in the immediate future .In addition, short papers will present the most recent research on the above mentioned topics. One paper will present a comprehensive overview of animal production from pasture in Ireland This book will be of interest to grassland and ruminant production scientists, mathematical modellers working on grazing systems, extension workers, students of agriculture and animal production and progressive livestock farmers.

Download or read book Mediterranean Type Ecosystems written by F.J. Kruger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of ecological convergence underlies the biogeographers' maps of world biome-types. It also determines the degree to which ecological principles, derived from research on particular populations, communities or ecosystems, are generally valid, and hence also to what extent resource management principles are general. To quote Di Castri and Mooney (1973): "In effect, in order to assess the transfer of technology, it is essential to know to what extent information acquired from studying one particular ecosystem is applicable to another ecosystem of the same type but situated in a different location. " The five relatively small, isolated, mediterranean-climate zones of the earth, each with its distinct fauna and flora, have provided the ideal testing grounds for this theory. A heritage of precisely focused ecosystems research has resulted, beginning with the international comparative analyses conducted by Specht (l969a, b) but with antecedents in earlier studies in South Australia (Specht and Rayson 1957, Specht 1973). Cody and Mooney (1978) reviewed the information available at the time for the four zones excepting Australia and concluded that the arrays of strategy-types to be found among the different biotas were so similar that they could be explained only in terms of the convergence hypothesis; nevertheless, evident differences in community organization and dynamics, especially phenol ogy, required closer study of resource availability and resource-use patterns to better explain relations between form and function overall, and to assess the degree of convergence at higher levels of organization than the population.

Download or read book Food from dry lands written by Th. Alberda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early seventies, scientists in Israel and The Netherlands started a cooperative project on actual and potential production under semi-arid conditions. In Israel research concentrated on primary production of natural pastures and small grain crops, and on the associated secondary production of small ruminants. Most of the experimental work was carried out at the Migda Experimental Farm in the semi-desert of the northern Negev where the long term average annual rainfall is 250 mm. In The Netherlands existing facilities in Wageningen were used for measuring growth, photosynthesis and transpiration of Negev pasture plants and small grains under controlled conditions, both as individual plants and as simulated swards and crops. The joint research program was initiated by the late N.H. Tadmor and A. Dovrat from Israel and by C.T. de Wit and Th. Alberda from The Netherlands and conducted by various scientists from both countries, some of whom are among the authors of this book. The experimental results first served as a basis for the development, calibration and validation of simulation models of the growth and water use of pasture and crops. Subsequently, additional models were developed, allowing incorporation of socio-economic considerations, both at the farm and regional level, so harnessing the research results for analysis of regional development possibilities.

Download or read book Science Cultivating Practice written by H. Maat and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science Cultivating Practice is an institutional history of agricultural science in the Netherlands and its overseas territories. The focus of this study is the variety of views about a proper relationship between science and (agricultural) practice. Such views and plans materialised in the overall organisation of research and education. Moreover, the book provides case studies of genetics and plant breeding in the Netherlands, colonial rice breeding, and agricultural statistics. Ideas affected the organisation as much as the other way round. The net result was an institutional development in which the values of academic science were rated higher than the values of practice. This book is a distinctive piece of work as it treats the dynamics of science in a European as well as in a colonial context. These different ecological and social environments lead to other forms of knowledge and experimentation as well as other ways of organising science.
