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

Natura 2000 is a coherent ecological network of special areas, designated under the Habitat and Birds EEC Directives, to assist in the maintenance of biodiversity in the European territory. It is now widely recognised that one of the most effective ways to maintain biodiversity is to preserve habitats in a favourable conservation status as required of Member States by the Habitat Directive. As a consequence, approaches are needed to define when habitats are of favourable conservation status and to assess the maintenance or the restoration of this condition. This could be partly achieved through the selection of appropriate indicators of favourable conservation status. Once such indicators have been identified and tested, they could be used for monitoring the impact of managing Natura 2000 sites, and could assist in achieving policy goals. Although many indicators have been proposed, particularly for forested habitats, few have been adequately field tested. Little research has been undertaken to identify indicators that are cost-effective, a key characteristic given that resources for habitat assessment and monitoring are often limited. Therefore, this research aims both to identify appropriate indicators to maintain favourable conservation status, and to evaluate their relative cost-effectiveness for two selected Natura 2000 sites: the Cansiglio Forest (North Italy) and the New Forest (South England). The following will highlight the results of the preliminary research.Natura 2000 is a coherent ecological network of special areas, designated under the Habitat and Birds EEC Directives, to assist in the maintenance of biodiversity in the European territory.

Towards cost-effective indicators to maintain Natura 2000 sites in favourable conservation status. Preliminary results from Cansiglio and New Forest

Spatial and temporal patterns of forest loss and fragmentation in Mexico and Chile.

Plant Disease Control through the use of Variety Mixtures

This paper represents an attempt to gather more precise information about the initial responses of seedlings of a dipterocarp species grown in deep shade to a dramatic increase in insolation. This was done by measuring the leaf temperature and stomatal conductance of seedlings grown in the shade characteristic at ground level in tropical rain forest, following the simulated formation of a large canopy gap over the seedlings

The initial responses of some tropical rain forest tree seedlings to a large gap environment.

Mutant instability in Septoria nodorum was investigated to determine its likely cause by comparing reversion rates of spontaneous and mutagen (NTG)-induced mutants Nitrogennon-utilizing mutants were selected for this by screening for resistance to chlorate All the NTG-induced mutants reverted to wild type, while only half the spontaneous mutants in the same genes reverted Possible explanations and the significance of the phenomenon to this pathogen are discussed
