Evidence of a highly complex phylogeographic structure on a specialist river bird species, the dipper (Cinclus cinclus)
2008
This study details the phylogeographic pattern of the white-throated dipper (Cinclus cinclus), a Palearctic, temperate, passerine bird that is exclusively associated with flowing water. Our results reveal a complex phylogeographic structure with at least five distinct lineages for the Western Palearctic region. As for many species of the Western Palearctic fauna and flora, this genetic structure is probably linked to the isolation of populations in different southern refuges during glacial periods. Furthermore, the isolation of populations in Scandinavia and/or Eastern regions, but also in Morocco and probably in Corsica, was accentuated by ecological and biogeographic barriers during Quate…

Does optimism mediate the relationship between Big Five and perceived stress? A study with Spanish adolescents
2021
Los resultados de investigación han mostrado la existencia de relaciones entre los Cinco Grandes factores de personalidad, Optimismo y Estrés Percibido. El objetivo del estudio es explorar, mediante modelos de ecuaciones estructurales, el posible papel mediador que se ha sugerido podría desempeñar Optimismo en esta relación. También, se explora a través de un análisis multi-grupo la invarianza por sexo de los resultados. Un total de 611 adolescentes españoles completaron de forma anónima los cuestionarios BFQ, LOT-R y PSS. Optimismo se asoció positivamente asociado con los rasgos de personalidad y negativamente con Estrés Percibido. El Estrés se relacionó negativamente con Estabilidad Emoc…
Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements
2019
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…
Arcadio Blasco: : Cinco esculturas urbanas (1986-1991)
2013
Con las primeras elecciones municipales democráticas en España después del franquismo, los nuevos ayuntamientos establecieron programas para reconstruir las ciudades españolas. Un aspecto de estos proyectos fue la creación de espacios públicos donde la gente pudiera encontrarse en un ambiente agradable. Estas áreas se cerraron al tránsito y se amueblaron con árboles, bancos y un nuevo tipo de esculturas artísticas. En la zona de Alicante, el ceramista Arcadio Blasco, ya conocido en Madrid y en Roma, creó cinco monumentos urbanos de gran escala. Después de veinte años, el destino de cada escultura ha sido diferente: alguna permanece en buenas condiciones, pero otras han sido tratadas de tal …
Microwave-Assisted Organocatalytic Enantioselective Intramolecular aza-Michael Reaction with α,β-Unsaturated Ketones
2011
An organocatalytic enantioselective intramolecular aza-Michael reaction of carbamates bearing conjugated ketones as Michael acceptors is described. By using 9-amino-9-deoxy-epi-hydroquinine as the catalyst and pentafluoropropionic acid as a co-catalyst, a series of piperidines, pyrrolidines, and the corresponding benzo-fused derivatives (indolines, isoindolines, tetrahydroquinolines, and tetrahydroisoquinolines) can be obtained in excellent yields and enantioselectivities. In addition, the use of microwave irradiation at 60 °C improves the efficiency of the process giving rise to the final products with comparable yields and enantiomeric excesses. Some mechanistic insights are also consider…
Cuerpos y mutaciones en el cine de ciencia-ficción durante los años cincuenta
1994
El cine de ciencia-ficción de los años cincuenta nos ofrece un testimonio ejemplar por su candidez de hasta dónde el patrón humano rige sin apenas deslices toda suerte de metamorfosis. La misma situación del género es en extremo curiosa: lejos de la imaginería gótica y romántica que alimentó las producciones Universal, también se distancia de las afecciones víricas, las prótesis teratológicas y la robótica de cuño informático que asaltan el cuerpo haciéndolo estallar en el moderno cine de terror.
Cinceles en la Edad del Bronce italiana: aspectos tecnológicos y tipológicos
2010
Bronze chisels are tools used “à percussion posée”; this means they need a minimum length and some functional parts (tang, body, blade); they could have a handle of perishable material and they were used with a hammer to work wood, bronze and other materials. Chisels can be classified following their functional parts; the first element is the shape (rod or socketed chisel); the second one is body section; the third one is tang section. Chronology and distribution of every type were identified to obtain a general view of this class of tools during the Italian Bronze Age.
Antibacterial activity of the enniatins A, A1, B, B1 produced by fusarium tricinctum in liquid culture, and cytotoxicity effects on Caco-2 cells

High-performance liquid chromatographic enantiomer separation and determination of absolute configurations of phosphinic acid analogues of dipeptides…
2003
The enantiomers of N-benzyloxycarbonyl-phosphinic pseudodipeptides and their N-benzyloxycarbonyl-α-aminophosphinic acid precursors as well as various other structural analogues were separated on a set of cinchona alkaloid-derived chiral anion-exchangers by HPLC in the reversed-phase mode. Semi-preparative scale chromatography provided single enantiomers in 100 mg quantities. The configurations of the enantiomers were assigned indirectly by enantioselective chromatography on the basis of the elution order and was confirmed by enantiomeric reference compounds.
