Los grupos de interés de las Fundaciones de Bizkaia: Margen Izquierda

El presente trabajo expone el marco en el que se desarrolla la relación entre las fundaciones de la margen izquierda vizcaína y los distintos stakeholders que la rodean. Se analizan algunos aspectos que deben ser tratados para la comprensión de los objetivos finales, realizando un estudio cada vez más especifico, desde las entidades no lucrativas hacia las fundaciones y sus grupos de interés. Se expone además diversos aspectos legales sobre las fundaciones, así como aspectos sobre información social y económica adecuados para este tipo de entidades. Finalmente, se estudian casos reales de fundaciones de ezkerraldea para posteriormente analizar dicha información con el fin de obtener conclusiones que arrojen luz a los objetivos expuestos.

Novel Papillomaviruses in Free-Ranging Iberian Bats: No Virus-Host Co-evolution, No Strict Host Specificity, and Hints for Recombination

Papillomaviruses (PVs) are widespread pathogens. However, the extent of PV infections in bats remains largely unknown. This work represents the first comprehensive study of PVs in Iberian bats. We identified four novel PVs in the mucosa of free-ranging Eptesicus serotinus (EserPV1, EserPV2, and EserPV3) and Rhinolophus ferrumequinum (RferPV1) individuals and analyzed their phylogenetic relationships within the viral family. We further assessed their prevalence in different populations of E. serotinus and its close relative E. isabellinus. Although it is frequent to read that PVs co-evolve with their host, that PVs are highly species-specific, and that PVs do not usually recombine, our results suggest otherwise. First, strict virus-host co-evolution is rejected by the existence of five, distantly related bat PV lineages and by the lack of congruence between bats and bat PVs phylogenies. Second, the ability of EserPV2 and EserPV3 to infect two different bat species (E. serotinus and E. isabellinus) argues against strict host specificity. Finally, the description of a second noncoding region in the RferPV1 genome reinforces the view of an increased susceptibility to recombination in the E2-L2 genomic region. These findings prompt the question of whether the prevailing paradigms regarding PVs evolution should be reconsidered.

Grupos topológicos

The main goal of this work is to give the reader a basic introduction into the subject of topological groups, bringing together the areas of topology and group theory.

Zonas de Brillouin de los grupos de capa

La base de datos de las zonas de Brillouin de los grupos de capa del Bilbao Crystallographic Server incluye tablas de vectores de onda y figuras que forman la base para la clasificación de las representaciones de los grupos de capa. Las propiedades de simetría de los vectores de onda se determinan por los llamados grupos del espacio recíproco y esta clasificación se compara con la que recoge el libro “Character Tables and Compatibility Relations of The Eighty Layer Groups and Seventeen Plane Groups” de Litvin & Wike.

Can environmental constraints determine random patterns of plant species co-occurrence?

Plant community ecologists use the null model approach to infer assembly processes from observed patterns of species co-occurrence. In about a third of published studies, the null hypothesis of random assembly cannot be rejected. When this occurs, plant ecologists interpret that the observed random pattern is not environmentally constrained - but probably generated by stochastic processes. The null model approach (using the C-score and the discrepancy index) was used to test for random assembly under two simulation algorithms. Logistic regression, distance-based redundancy analysis, and constrained ordination were used to test for environmental determinism (species segregation along environmental gradients or turnover and species aggregation). This article introduces an environmentally determined community of alpine hydrophytes that presents itself as randomly assembled. The pathway through which the random pattern arises in this community is suggested to be as follows: Two simultaneous environmental processes, one leading to species aggregation and the other leading to species segregation, concurrently generate the observed pattern, which results to be neither aggregated nor segregated - but random. A simulation study supports this suggestion. Although apparently simple, the null model approach seems to assume that a single ecological factor prevails or that if several factors decisively influence the community, then they all exert their influence in the same direction, generating either aggregation or segregation. As these assumptions are unlikely to hold in most cases and assembly processes cannot be inferred from random patterns, we would like to propose plant ecologists to investigate specifically the ecological processes responsible for observed random patterns, instead of trying to infer processes from patterns
