Ictiólogos de la Argentina: Eduardo Ladislao Holmberg.

This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina. Hugo L. López (Texto en espanol.

Monte Carlo simulation of streamflow of the Salt River, Arizona

EXTRACT (SEE PDF FOR FULL ABSTRACT): Evaluations of the impact of climate change (such as a greenhouse effect) upon water resources should represent both the expected change and the uncertainty in that expectation. Since water resources such as streamflow and reservoir levels depend on a variety of factors, each of which is subject to significant uncertainty, it is desirable to formulate methods of representing that uncertainty in the forcing factors and from this determine the uncertainty in the response variables of interest. We report here progress in the representation of the uncertainty in climate upon the uncertainty in the estimated hydrologic response.

Un tal Eduardo Ladislao…

Esta serie tiene como objetivo rescatar parte de las reflexiones, ideas, pensamientos, comentarios… de aquellos que transitaron el complejo y fascinante camino de las Ciencias Naturales. Por ello, a través de estas líneas, hago una fuerte convocatoria para que colegas de diferentes disciplinas se acerquen para colaborar con esta idea, ya sea desde este espacio o de cualquier otro. Se preguntaran ¿para qué? y ¿por qué? Yo creo que es una manera de reflejar diferentes contextos históricos y acercar nuestros referentes a las jóvenes generaciones. Esto último me parece muy importante, ya que existe una tendencia generalizada de obviar parte del pasado, lo que dificulta comprender el presente y proyectar el futuro.
