Determining the main ecological drivers of vector distribution and how predicted changes in these drivers may alter their future distributions is therefore of major importance. However, the drivers of vector populations are largely specific to each vector species and region. Here, we identify the most important human-activity-related and bioclimatic predictors affecting the current distribution and habitat suitability of the mosquito Culex pipiens and potential future changes in its distribution in Spain. We determined the niche of occurrence (NOO) of the species, which considers only those areas lying within the range of suitable environmental conditions using presence data. Although almost ubiquitous, the distribution of Cx. pipiens is mostly explained by elevation and the degree of urbanization but also, to a lesser extent, by mean temperatures during the wettest season and temperature seasonality. The combination of these predictors highlights the existence of a heterogeneous pattern of habitat suitability, with most suitable areas located in the southern and northeastern coastal areas of Spain, and unsuitable areas located at higher altitude and in colder regions. Future climatic predictions indicate a net decrease in distribution of up to 29.55%, probably due to warming and greater temperature oscillations. Despite these predicted changes in vector distribution, their effects on the incidence of infectious diseases are, however, difficult to forecast since different processes such as local adaptation to temperature, vector-pathogen interactions, and human-derived changes in landscape may play important roles in shaping the future dynamics of pathogen transmission., El estudio ha sido parcialmente financiado por los proyectos PGC2018-095704-B-100 y CGL2012-30759 del Ministerio de Economía y Competitividad, los proyectos IB16121 y IB16135 de la Junta de Extremadura y el proyecto PI18/00850 del Instituto de Salud Carlos III y la Unión Europea (ERDF/ESF, Investing in your future)., Peer reviewed

Understanding the role and impact of reticulation in phylogenetic inquiry has improved with extended use of high throughput sequencing data. Yet, due to the dynamism of genomes over evolutionary time, disentangling old hybridization events remains a serious challenge. Phalacrocarpum is one of the 27 Iberian endemic plant genera, currently considered monotypic but including three subspecies. Its uncertain phylogenetic relationships within tribe Anthemideae (Asteraceae) point to an Early Miocene divergence from its sister group, and its persistent taxonomic instability has been proposed to be due to hybridization. We aim at understanding the evolutionary history of this genus using SNPs called from a genotyping-by-sequencing (GBS) analysis, Sanger sequences —from three plastid DNA regions (psbJ-petA, petB-petD, trnH-psbA) and the nuclear ribosomal ITS regions (cloned)— as well as leaf morphometric multivariate analysis. SNP data and Sanger sequences strongly support the unforeseen existence of a cryptic species in the eastern populations of P. oppositifolium subsp. anomalum. Broad molecular and morphometric patterns of variation found in conflictive populations from the Sanabria Valley region convincingly identify a recent previously undocumented hybrid zone. By contrast, evidence is less conclusive on relationships between subspecies hoffmannseggii, oppositifolium and a second conflictive group along the border of Galicia and Portugal (Orense massifs). Although genetic clustering analysis of SNP data suggests that the former subspecies was the mother progenitor in hybridization events that gave rise to the other two groups, we found considerable uniqueness of ITS ribotypes and plastid haplotypes in them. This result, in the context of Pleistocene climatically-driven range shifts in NW Iberian Peninsula, can be due to periods of isolation, genetic bottlenecks and drift superimposed on old hybridization events. Our study confirms the idea that unraveling old hybridization events may be compromised by the suite of evolutionary processes accumulated subsequently, particularly in areas with a history of climatic instability., Peer reviewed

Los datos corresponden a un estudio experimental sobre el compromiso entre del riesgo de depredacion e inhanición en el Carbonero común (Parus major) y su efecto sobre el peso y el metabolismo basal. Encontramos que aves cautivas en aviarios al exterior, si disponen del tiempo necesario, promueven cambios en el coste energetico de mantenimiento (tasa metabolica basal) antes que el peso, que indicaria el nivel de reservas interno. Estos resultados tienen gran relevancia dado que cuestionan el enfoque tradicional los estudios de energética en vertebrados endotermos, que primava la regulación de las reservas como practicamente el unico mecanismo adaptativo de regulacion., Peer reviewed

This dataset is composed of the input files of the numerical models for simulating Amposta fault stability during different phases of the project and poromechanical pressure changes induced by shear slip. The input files of each numerical simulation are included in a folder. The names of the folders and the description of the model are: - “1_Oil_production”: simulation of oil production and 7 years of post-production to quantify the changes in the Amposta fault stability - “2_Overpressure_plus_buoyancy_cushion”: simulation of the cushion gas injection considering both the effect of pore pressure increase and buoyancy to quantify the changes in the Amposta fault stability - “3_Overpressure_cushion”: simulation of the cushion gas injection considering only the effect of pore pressure increase (without gravity) to quantify the changes in the Amposta fault stability - “4_Buoyancy_cushion”: simulation of the cushion gas injection considering only the buoyancy of the gas to quantify the changes in the Amposta fault stability - “5_Buoyancy_full_capacity”: simulation of the gas storage at its maximum capacity considering only the buoyancy of the gas to quantify the changes in the Amposta fault stability - “6_Poromechanical_pressure_changes”: simulation of the pore pressure changes induced by shear slip and its effects in the short and long term., Each folder includes a file with the name of the folder and ended as “_gen.dat” that contains the input data of the model, including material properties, initial and boundary conditions and the time intervals. There is also a file ended as “_gri.dat” that includes the information on the mesh. The “root.dat” includes the name of the model. To run simulations, just execute the Code_Bright executable “Cb_vX_Y.exe” in a folder that contains the three input files and the executable, where X and Y denote the used version of the executable., With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S), Peer reviewed

Light microscopical sections of the proximal retina of female (D, E) and male (F, G) Coraebus undatus. If the crystalline cone extensions are visible as varicosities between adjacent photoreceptor cells, then it is possible to infer the ommatidial chirality and map the chiral ommatidia accross the section., We investigated the retina and coloration of one member of this family, the flathead oak borer Coraebus undatus using microscopy, spectrometry, polarimetry, electroretinography and intracellular recordings of photoreceptor cell responses. The compound eyes are built of a highly unusual mosaic of mirror-symmetric or chiral ommatidia that are randomly rotated along the body axes. Each ommatidium has eight photoreceptors, two of them having rhabdomeres in tiers. The eyes contain six spectral classes of photoreceptors, peaking in the UV, blue, green and red. Most photoreceptors have moderate polarization sensitivity with randomly distributed angular maxima. The beetles have the necessary retinal substrate for complex color vision, required to recognize conspecifics and suitable for a targeted design of color traps. However, the jewel beetle array of freely rotated ommatidia is very different from the ordered mosaic in insects that have object-directed polarization vision. We propose that ommatidial rotation enables the cancelling out of polarization signals, thus allowing stable color vision, similar to the rhabdomeric twist in the eyes of flies and honeybees., Peer reviewed
