Diagnosis of sibling species of Drosophila involved in the colonization of North America by D. subobscura
1997
To determine the effects of the recent colonization of the west coast of North America by the Palaearctic species Drosophila subobscura on the dynamics of the Drosophila populations, the sibling species D. athabasca and D. azteca must be classified unambiguously. We have characterized these two species using three molecular techniques: allozymes, mtDNA and RAPDs. All three techniques allow the classification of any individual as belonging to either species. The study of five localities in northern California and southern Oregon show that the area of overlap is larger than previously described.
Molecular phylogeny of the harvestmen genus Sabacon (Arachnida: Opiliones: Dyspnoi) reveals multiple Eocene–Oligocene intercontinental dispersal even…
2012
Abstract We investigated the phylogeny and biogeographic history of the Holarctic harvestmen genus Sabacon , which shows an intercontinental disjunct distribution and is presumed to be a relatively old taxon. Molecular phylogenetic relationships of Sabacon were estimated using multiple gene regions and Bayesian inference for a comprehensive Sabacon sample. Molecular clock analyses, using relaxed clock models implemented in BEAST, are applied to date divergence events. Biogeographic scenarios utilizing S-DIVA and Lagrange C++ are reconstructed over sets of Bayesian trees, allowing for the incorporation of phylogenetic uncertainty and quantification of alternative reconstructions over time.

La expansión geográfica de la renta del tabaco
2007
El monopolio real del tabaco fue decretado sólo para la Corona de Castilla en 1636. Debido a su reconocida eficacia, los gobernantes españoles intentaron implantarlo allá donde fuese políticamente posible. Después de la guerra de Sucesión, fue establecido en la Corona de Aragón, ya que estos territorios perdieron entonces su régimen foral de autonomía. Como las provincias vascas y Navarra consiguieron conservar su régimen foral, el Gobierno español no pudo someter allí el régimen general del estanco tabaquero y tuvo que contentarse con negociar soluciones que no perjudicasen al estanco general. Finalmente, en el contexto de las reformas borbónicas en América, la Renta del Tabaco fue gradual…

Welfare State Development, Individual Deprivations and Income Inequality: A cross-country analysis in Latin America and the Caribbean
2019
Several scholars have confirmed the role that the welfare state (WS) plays in reducing poverty, promoting equality and ensuring the common wellbeing. One of the limitations of the scholarship has been the conceptualization and operationalization of the WS and poverty as one-dimensional variables. The purpose of this paper is to examine the relationship between welfare state development –as a one-dimensional and multidimensional variable-, single-dimensions deprivations and income inequality in Latin America and the Caribbean, before and after controlling for demographic and cyclical factors. The WS is operationalized taking into account its multidimensional nature. Three individual deprivat…
La música preexistente en la comedia americana de los años ochenta: "Trading Places" (1983)
2009
En este trabajo se analiza el uso de la música de concierto preexistente en una de las comedias estadounidenses más interesantes de los años ochenta: "Trading Places", dirigida en 1983 por John Landis y titulada en España con el poco afortunado título de "Entre pillos anda el juego". La denominación original "Trading Places" es la que se utiliza en este trabajo puesto que define de forma más precisa la trama de la película y sirve para comprender el origen de la mayoría de la música preexistente. Landis colaboró de forma muy directa con el prestigioso compositor de bandas sonoras Elmer Bernstein, que preparó una partitura basada en música preexistente. Bernstein presenta en el filme tres ti…
Wordarrows: El poder representativo del lenguaje en la obra de no ficción de N. Scott Momaday
2012
This article focuses on two non-fiction works by Native American author N. Scott Momaday: his 1969 historical memoir The Way to Rainy Mountain and his essay collection The Man Made of Words. It specifically tackles performative conceptions of language in the Kiowa storytelling tradition, where words are experienced as speech acts that have the power to intervene in surrounding realities. Taking into account 20th century ethno-cultural and linguistic policies in the United States, the article also reflects on the role indigenous languages may play in contemporary Native American Literature, which has most often been written in English.

High-resolution records of growth temperature and life history of two Nacella limpet species, Tierra del Fuego, Argentina
2020
Stable isotope ratios in patelloid limpets of the genus Patella have been established as proxies for coastal environmental change at sub-monthly resolution along the eastern North Atlantic and Mediterranean Sea. Nacella deaurata (Gmelin, 1791) and N. magellanica (Gmelin, 1791) are common intertidal species of patelloid limpets inhabiting the coast of Tierra del Fuego, Argentina/Chile and are commonly found in Holocene archaeological deposits. Here, we examine oxygen and carbon isotope ratios (δ18Oshell and δ13Cshell, respectively) of modern specimens of N. deaurata and N. magellanica to test the hypotheses that: 1) they form their shells in isotopic equilibrium with ambient water; and 2) pr…
