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.

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 Systems Analysis in Forest Resources written by Greg J. Arthaud and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems analysis in forestry has continued to advance in sophistication and diversity of application over the last few decades. The papers in this volume were presented at the eighth symposium in the foremost conference series worldwide in this subject area. Techniques presented include optimization and simulation modelling, decision support systems, alternative planning techniques, and spatial analysis. Over 30 papers and extended abstracts are grouped into the topical areas of (1) fire and fuels; (2) networks and transportation; (3) forest and landscape planning; (4) ecological modeling, biodiversity, and wildlife; and (5) forest resource applications. This collection will be of interest to forest planners and researchers who work in quantitative methods in forestry.
Download or read book Systems Analysis and Simulation in Ecology written by Bernard C. Patten and published by Elsevier. This book was released on 2013-09-11 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems Analysis and Simulation in Ecology, Volume III, and its companion, Volume IV, grew out of a symposium, Modeling and Analysis of Ecosystems, held at the University of Georgia, 1-3 March 1973. The purposes of the meeting were to (i) review the status of ecosystem modeling, simulation, and analysis; (ii) provide a forum for interaction between U.S. International Biological Program (IBP) Biome modeling programs and selected non-IBP investigations involving systems approaches to ecosystem analysis; and (iii) identify and promote dialogue on key issues in macrosystem modeling. The volume is organized into two parts. Part I treats ecosystem modeling in the U.S. IBP. The introductory chapter is followed by five chapters describing grassland, deciduous forest, desert, tundra, and coniferous forest biome modeling. The concluding chapter is one of critique and evaluation. Part II is devoted mainly to freshwater ecosystems, grading into the estuarine system in the last chapter. The five chapters of this section encompass a simple thermal ecosystem, small woodland streams, a reservoir, one of the Great Lakes, a lake reclaimed from eutrophication, and a major estuary under stress of human impact.
