Ocean acidification affects fish spawning but not paternity at CO2 seeps
2016
Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ between sites with ambient versus elevated CO2 concentrations. Dominant males did, however, experience significantly lower rates of pair spawning at elevated CO2 levels. Despite the higher r…
Epitalamios e himeneos. Iconografía y literatura nupcial en las cortes del Barroco.
2010
En este estudio se aborda, bajo una visión general, los textos y las imágenes presentes en algunos epitalamios e himeneos: composiciones poéticas de los siglos XVII y XVIII, realizadas en las cortes europeas con motivo de los matrimonios concertados entre sus miembros. Sus imágenes emblemáticas y simbólicas, son de gran interés para la historia del arte, pues se inspiran en las composiciones de los libros de emblemas del periodo y desarrollan temas habituales en la literatura matrimonial. No obstante, lo más significativo son los mensajes políticos que difunden, fundamentalmente los beneficios políticos de las uniones dinásticas. This study deals, from a general point of view, with the text…
Alcohol boosts pheromone production in male flies and makes them sexier
2020
The attraction of Drosophila melanogaster towards byproducts of alcoholic fermentation, especially ethanol, has been extensively studied 1–4. However, the adaptive value of this behavior has not been elucidated. Previous studies have suggested anthropomorphic interpretations of D. melanogaster behavior towards alcohols 5,6. Here, we instead assert that there exists a simple yet vital biological rationale for alcohol contact and consumption by these insects. We show that exposure to alcohols, especially methanol, results in an immediate amplification of fatty acid ester pheromone levels, which in turn elevates the probability that a male will successfully compete for a female during courtshi…
Nuevos datos sobre la sociedad y el derecho celtibéricos: la regulación de la cabaña ganadera
2012
Basándose en varios documentos medievales, mediante los cuales los reyes de la Corona de Aragón restablecieron un tribunal especial consuetudinario (tribunal del ligallo) para devolver a sus dueños el ganado mostrenco, el Autor determina el origen de este tribunal como antiquísima institución celtibérica y reconstruye su funcionamiento y papel en las sociedades célticas de la Península Ibérica. Esta corte de justicia, propia de todas las agrupaciones celtibéricas de siete miembros (oppida), se reunía dos veces por año, coincidiendo sus sesiones con las dos grandes festividades de Beltene (1 de mayo) y de Samain (1 de noviembre), y tenía como misión resolver todos los conflictos pecuarios su…
Mínguez, Víctor; Rodríguez Moya, Inmaculada. Napoleón y el espejo de la Antigüedad. Arqueología de las imágenes del poder
2015
En Napoleón y el espejo de la Antigüedad, el Dr. Víctor Mínguez y la Dra. Inmaculada Rodríguez culminan una intensa labor investigadora iniciada con el proyecto I+D “Arqueología de las imágenes del poder. El arte imperial romano como modelo iconográfico en las Cortes Europeas desde el Renacimiento a Napoleón” (P1.1B2012-02), integrado en el Plan de Investigación de la Universitat Jaume I y dirigido por el Dr. Víctor Mínguez. Encabezado por la presentación del prestigioso doctor Philippe Bordes, uno de los máximos especialistas en historia del arte de la Revolución francesa y de la época del Imperio, este ambicioso proyecto elabora un exhaustivo recorrido a través del estudio de los modelos …
Regulation of cuticular hydrocarbon profile maturation by Drosophila tanning hormone, bursicon, and its interaction with desaturase activity
2016
International audience; Shortly after emergence the exoskeleton (cuticle) of adult insects is rapidly expanded, hardened (sclerotized), and pigmented (melanized). In parallel with this process, the oenocytes, which are large polyploid cells located below the abdominal epidermis, secrete onto the cuticle a cocktail of cuticular hydrocarbons (CHs) and waxes. These improve the waterproofing of the cuticle, and also provide important chemosensory and pheromonal cues linked with gender, age, and species differentiation. The hardening and pigmentation of the new cuticle are controlled by the neurohormone, bursicon, and its receptor, encoded by the DLGR2 receptor, rickets (rk); by contrast, little…
Sexual selection for genetic quality: disentangling the roles of male and female behaviour
2009
According to the good genes model of sexual selection, females choose males of good heritable genetic quality to obtain offspring with high fitness. However, better mating success of high-quality males can also be brought about by direct interference competition between males, or simply through elevated activity of high-quality males. We examined the roles of different processes leading to sexual selection for genetic quality in Drosophila montana. We manipulated genetic quality of male flies by inducing mutations with ionizing radiation. We then recorded the effects of inherited heterozygous mutations on several aspects of mating behaviour of males and females in two experiments. We found …
Gertrude Bonnin on Sexual Morality
2021
This paper examines attitudes to sexual morality held by the Yankton Dakota author and activist Gertrude Bonnin (1876–1938), better known by her penname Zitkála-Šá (Red Bird in Lakota). Bonnin’s concerns encompass several themes: the victimization of Indian women, disintegration of Native courtship rituals, sexual threats posed by peyote use, and the predatory nature of Euro-American men. This critique as a whole — in which a ‘white invasion,’ in her words, leads to a corruption of Native sexuality — sometimes produces inconsistencies, particularly regarding Bonnin’s statements on the alleged sexual perils of peyote. Her investigations into the Oklahoma guardianship scandals of the 1920s, h…
The Barratry of the Shipmaster in Early Modern Law: The Approach of Italian and English Law Courts
2019
Summary For a long time, the concept of barratry (at least in its maritime meaning) was one and the same on both sides of the Channel. The barratry of the shipmaster was part of the mercantile usages, and it identified the intentionally blameworthy conduct of the master. When law courts began to decide on insurance litigation they were confronted with a notion quite alien to them. Broadly speaking, the shipmaster’s barratry could well be considered a fraud of sort. But in order to decide on its occurrence in a specific case, law courts had to analyse it in legal terms, and so according to the specific legal categories of their own system. The point ceases to be trivially obvious if we think…
International Courts and the Crime of Genocide
2013
En este trabajo realizo un análisis jurídico de los elementos constitutivos (tanto subjetivos como objetivos) del crimen de genocidio, tal y como han sido interpretados y aplicados por la jurisprudencia internacional. En concreto, se estudia la jurisprudencia de la Corte Internacional de Justicia, del Tribunal Internacional Penal para la antigua Yugoslavia y del Tribunal Internacional Penal para Ruanda sobre el crimen de genocidio.
