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.

Diferentes iniciativas de restauracion pretenden mitigar la vasta deforestacion y degradacion forestal
existentes en el mundo. La “restauracion pasiva”, en la cual los campos agricolas abandonados son
sujeto de la sucesion secundaria, es con frecuencia lenta debido a limitaciones bioticas y abioticas. La
“restauracion activa”, basada sobre todo en la plantacion de arboles, puede ser cara si se restauran territorios
amplios. Sugerimos la utilizacion de “islotes forestales” como una alternativa para la restauracion
de paisajes agricolas extensos, particularmente en ambientes de productividad baja. Este enfoque implica
la plantacion de numerosos y densos nucleos de vegetacion lenosa nativa que incrementan la biodiversidad
y proporcionan una variedad de servicios ambientales. Si los campos de alrededor son abandonados,
los islotes actuan como fuentes de propagulos de especies forestales, acelerandose el desarrollo
de los matorrales y bosques. Por el contrario, si los campos de alrededor son utilizados para cultivos y
pastos, los islotes pueden incrementar el valor de conservacion del paisaje y ofrecer un potencial de generacion
de rentabilidad economica. En este trabajo revisamos los principales enfoques para la restauracion
forestal y evaluamos las fortalezas y debilidades del modelo de los islotes forestales en mares agricolas.

Creación de islotes forestales para reconciliar restauración ecológica, conservación y uso agrícola

summary Despite the adoption of Arabidopsis thaliana as a model plant system and the plethora of molecular information being obtained from its use, it is disappointing that the scientific community has not devised a cell signalling model integrating and visualizing these data. Lack of common systems of nomenclature and the sheer size and complexity of the task inhibit any individual from bringing together the knowledge into a unified structure. There are clearly many aspects of cell biology that are similar, even between plants and animals, that could facilitate development of a generic model. A gene-coding or nucleotide classification system which is 'user-friendly' would be beneficial to building such a model and enable rapid identification of orthologues of genes from different organisms. Whilst some international projects seek to address the problem of assigning unique numbers to genes, none suggest a nucleotide classification system that provides biological information that is transparent within the code. This paper discusses these issues and identifies the need for a more formal, semi-automated approach to modelling signal transduction utilizing the strengths of the proposed classification approach. By way of illustration, an example of a possible nucleotide function code is suggested, to demonstrate more clearly the benefits of such a system. Further discussion of this topic will be encouraged on websites ( and ).
