The Theory of Island Biogeography

THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

Climate change 2014 - Synthesis Report

This first report of the Millennium Ecosystem Assessment describes the conceptual framework that is being used in the MA. It is not a formal assessment of the literature, but rather a scientifically informed presentation of the choices made by the assessment team in structuring the analysis and framing the issues. The conceptual framework elaborated in this report describes the approach and assumptions that will underlie the analysis conducted in the Millennium Ecosystem Assessment. The framework was developed through interactions among the experts involved in the MA as well as stakeholders who will use its findings. It represents one means of examining the linkages between ecosystems and human well-being that is both scientifically credible and relevant to decision-makers. This framework for analysis and decision-making should be of use to a wide array of individuals and institutions in government, the private sector, and civil society that seek to incorporate considerations of ecosystem services in their assessments, plans, and actions.

Ecosystems and human well-being: a framework for assessment

Molecular genetic markers and other enabling technologies are now sufficiently developed for exploitation in breeding programmes. They allow the possibility of accelerating, and improving the efficiency, of breeding for abiotic and biotic stress tolerances. Barley is a good model species in which to demonstrate this. Barley is a diploid species in which genetic analysis is relatively easy, its short life cycle and inbred nature has also provided for good physiological research. The results of genetic and physiology studies can now be exploited more efficiently in breeding using the tools of contemporary biotechnologies. A programme of work has been initiated aimed at developing more stable yields in barley (Hordeum vulgare) for droughted, low input agricultural conditions of Mediterranean rim countries. Various molecular breeding approaches are to be compared which vary in gene donors, recipients and methods. Two of the approaches exploit wild barley (H. spontaneum) as a source of genetic variation for abiotic stress tolerance, the third uses an adapted landrace. Results from controlled environment experimentation will be compared with field performance in naturally stressed environments of N. Africa. The work will provide a testing ground for the application of ideas and technologies developed from research.

Avoidance and tolerance of foliar disease in barley: opportunities for improvement.

A map for valuing ecosystem services in the 480 km2 Frome catchment, to investigate scenarios of change in land use, was internet crowd-sourced. Scouts mapped deer habitats in 15% of the 30 km2 Arne Parish, while 143 residents volunteered data on deer sightings in the 5-year community survey.
