Title A name given to the resource Una breve historia del conocimiento y uso de la biodiversidaden la frontera sur de México Creator An entity primarily responsible for making the resource Juan Jacobo Schmitter-Soto, Ramón Mariaca-Méndez, María Lorena Soto-Pinto Description An account of the resource Se ofrece una historia del estudio científico sobre el conocimiento y el uso de la biodiversidad y su conservación, con énfasis en el sur de México, donde se maximizan a la vez la diversidad natural y la marginación social. Abandonada a sí misma por siglos, la región sur de México se ha visto envuelta en las últimas décadas en un proceso depredatorio impresionante. El surgimiento de instituciones científicas en la región desde hace casi medio siglo ha ayudado a conocer el potencial físico, biótico y humano existente y a establecer estrategias para su manejo, ante problemas tales como la globalización y el cambio climático. Aunque la historia de la conservación biológica como tal es mucho más reciente que la del desarrollo rural, existe entre ambas disciplinas una interdependencia crucial. La biodiversidad, su conocimiento, uso y conservación, debe no solo ser compatible con la justicia social, sino contribuir a ésta.

Title A name given to the resource Una cuestión de escala: sociedad, ambiente, tiempo y territorio A question of scale: society, environment, time and territory Creator An entity primarily responsible for making the resource Carlos E. Reboratti Description An account of the resource A medida que los limites disciplinares se van haciendo cada vez más borrosos y se produce un acercamiento entre campos del saber antes tan alejados como la historia y la ecología (paradójicamente paralelo a una fuerte especialización dentro de cada una de ellas), se hacen evidentes las tensiones que se generan cuando se intenta compatibilizar las 'miradas' de cada una de ellas sobre su objeto de estudio. Estas miradas podemos resumirlas alrededor del tema de las escalas, las aproximaciones técnico-conceptuales que cada disciplina utiliza para reducir su objeto de estudio a una dimensión manejable. Esta diferencia se puede encontrar bajo dos dimensiones no excluyentes: el tiempo y el espacio. Las escalas utilizadas para analizar cada una de estas dimensiones son variables y hasta ahora habían sido objeto de controversia en el seno de las humanidades. Pero si introducimos en la discusión la variable que en forma genérica podemos llamar 'ambiental', la tensión se hace muy difícil de solucionar, ya que vamos a tener que tratar de compatibilizar por un lado disciplinas, como la geología, cuya unidad de trabajo es 1 millón de años o la geomorfología, que trabaja con decenas de miles de años, con la historia, cuyo sujeto de análisis no tiene mas de 12.000 años de haber aprendido a cultivar la tierra. Por no hablar de disciplinas del presente, como la geografía, o la sociología, cuyo rango temporario raramente va mas atrás de una generación de personas. De toda esta controversia surgen algunas preguntas básicas, tales como: existe una escala espacial que compatibilice las disciplinas que coinciden en el ambiente? Que significa macro, micro y meso en cada disciplina? Es posible relacionar los ciclos temporales que determina cada disciplina? Como se construye conceptualmente un campo interdisciplinario como la historia ambiental o la geografía histórica?As disciplinary limits become blurred and knowledge fields so distant as history and ecology come closer (paradoxically together with a strong specialization within each of them), the tensions generated when we try to harmonize each field's approach on its object of study are more and more clear. We might summarize those approaches around the subject of scales, techno-cultural approximations used by each discipline in order to reduce its object to a workable dimension. We might find those differences under two non-excluding dimensions: time and space. The scales used to analyze each of them are variable and so far have been object of controversy within the humanities. However, introducing the variable which we may call generically 'environmental', the tension becomes very difficult to solve, since we will have to harmonize, on the one hand, the disciplines, such as geology, whose work unit is that of 1 million years, or geomorphology, which works with tens of thousands of years, with history, working with 12.000 years of land cultivation. Not to mention current disciplines, as geography, sociology, whose time span rarely goes beyond one generation. Two basic questions arise from all that controversy: is there a special scale which harmonizes the disciplines that coincide on the environment? What are the meanings of macro, micro and middle for that discipline? Is it possible to relate the time cycles which determine each discipline? How is a conceptual interdisciplinary field built, such as environmental history or historical geography?

The Christian believer’s mission is the recognition of his/her intimate relationship with the ecosystem that goes beyond the not alive human, but must be understood as the context of his founding experience with God. The destruction of the environment is a sin in the eyes of God, who entrusted the man with its dominion, which must be assumed in terms of care, protection and defense, including the promotion of human dignity in every living being, as it is the glory of God.

Title A name given to the resource Una evaluación de los índices bibliométricos I e Is de Molina-Montenegro & Gianoli aplicada a investigadores en ciencias ecológicas en Chile An assessment of the bibliometric indices I and Is of Molina-Montenegro & Gianoli applied to researchers in ecological sciences in Chile Creator An entity primarily responsible for making the resource MARIO GEORGE-NASCIMENTO Description An account of the resource El interés por medir la producción científica ha originado un creciente número de índices. En este comentario examino críticamente los índices I e Is propuestos por Molina-Montenegro & Gianoli (2010; en este número), y los criterios empleados por estos autores para incorporar o excluir a científicos de su base de datos de investigadores chilenos en ecología. Además analizo la relación estadística entre los índices de producción científica I, Is y h de Hirsch, y las variables que los componen. Para ello empleo análisis de correlación y de regresión lineal. Los resultados muestran que luego de la corrección por el número de coautores y de autocitas que incorpora el índice I, este está principalmente asociado al log10 del número de alocitas, y mantiene una alta correlación con el índice h. Esto sugiere que el número de coautores y de autocitas no son predictores importantes de las diferencias entre ambos índices. En cambio, el índice Is es el único que disminuye con la edad científica, lo que se considera un efecto indeseable, y resultante de corregir mediante la división del valor del índice I por la edad científica. Al examinar los residuos de la regresión entre el log10 del número de alocitas y la edad científica se distingue nítidamente a quiénes habría que promover, contratar o premiar, lo que constituye una manera más simple y directa de evaluar comparativamente la producción de un investigador.The interest in measuring the scientific output has led to an increasing number of indices being proposed. In this commentary I critically examine the indices I and Is proposed by Molina-Montenegro & Gianoli (2010; in this issue), and the criteria employed by these authors to incorporate or exclude scientists from their database of Chilean researchers in ecology. I also assess the statistical relationship between the indices of scientific output I, Is and Hirsch's h, and the primary variables that compose them. To do that I use correlation and linear regression analyses. Results show that the I index is highly associated to the number of co-authors, and keeps a high positive and significant correlation with the h index, after adjusting by log10 of the number of alocitations and the number of self-citations. This suggests that the number of co-authors and self-citations are not important predictors of the differences between h and I. In contrast, the Is index decreases with scientific age, which would be an undesirable outcome, and a result of dividing the I index by the scientific age. I suggest that inspecting residuals of the regression between the log10 of the number of alocitations and the scientific age is a simple and straightforward way to assess whether a scientist should be promoted, hired or awarded.
