Proposal of a typology of Spanish mountain lakes and ponds using the composition of functional groups of macrophytes

Before establishing the ecological status of lakes, the Water Framework Directive requires their classification in types. Typically, the development of a typology has been based on abiotic variables. However, for the typology to have validity, the classification of lakes should be corroborated with the biological communities in the bodies of water. In this study, to develop a biologically relevant typology, the natural variability of the macrophyte communities in mountain lakes and ponds was evaluated. The use of functional groups of macrophytes as an alternative to the taxonomic approach was also evaluated. Thirty-one reference mountain lakes and ponds, located in the northwest quadrant of the Iberian Peninsula, were included in the study. The functional groups of macrophytes were based on the inorganic source of carbon used in photosynthesis. The typology developed from the functional groups was more conclusive than the classification derived from the taxonomic data. The primary determinants of the variability in the composition of the functional groups of macrophytes among the different types of lakes were the changes in the pH and in the orthophosphate concentration related to the decomposition of macrophytes. The submerged macrophytes dominated in the lakes with low concentrations of orthophosphate and the highest levels of alkalinity. In the lakes with lower pH values, the floating-leaved macrophytes were the dominant plants when the phosphorus concentration was higher, whereas at intermediate concentrations of phosphorus, the bryophytes and isoetids were more abundant; these two lake types were differentiated because of the dominance of the bryophytes in those lakes with higher acidity

El packaging como estrategia de fidelización en el sector hotelero

[EN] In this project, we talk about a strategy of promotion and loyalty to which less attention has been paid over time due to the appearance of new technologies but which still exists and is effective despite being more traditional. This strategy includes the use of packaging and marketing to establish a loyalty relationship with the customer. We focus on this strategy used in luxury hotels, using as an example a series of products designed for the Hotel Arts in Barcelona.[CAT/VA] En este projecte es parla d'una estratègia de promoció i fidelització a què amb el temps s'ha anat prestant menys atenció degut a l'aparició de les noves tecnologies però que encara existix i és efectiva a pesar de ser més tradicional. Esta estratègia comprén l'ús del packaging i el màrqueting a l'hora d'establir una relació de fidelitat amb el client. Ens centrem en esta estratègia utilitzada en els hotels de luxe, usant com a exemple una sèrie de productes dissenyats per a l'Hotel Arts de Barcelona.Núñez Fernández, CA. (2017).

Reproduction, longevity and life table parameters of Monosteira unicostata (Hemiptera: Tingidae) at constant temperatures

Information on the effect of temperature on biological parameters of phytophagous insects is one of the tools in IPM programs, as it allows prediction of risk situations in the field. This work reports the effect of temperature on reproductive parameters and longevity of one of the most important current pests of almond orchards in the Mediterranean basin, the poplar lace bug, Monosteira unicostata (Mulsant & Rey) (Hemiptera: Tingidae). The temperatures tested were 22, 25, 28, 31, 34 and 37ºC, always at 60 ± 10% relative humidity and under a L16:D8 photoperiod. Extreme temperatures had an adverse effect on preoviposition period, total fecundity and daily fecundity while increasing values of oviposition period and adults longevity were registered for decreasing temperatures. Male longevity was higher than female longevity, and mortality pattern differed between sexes for all temperatures but 37ºC. The nonlinear Lactin model described accurately the effect of temperature on the intrinsic rate of natural increase of M. unicostata populations and predicted the optimum temperature for population increase at 34.1ºC, at which the population doubling time is 3.6 days. Produced values of lower and upper thresholds for M. unicostata populations were 14.8 and 38.8ºC, respectively. This characterizes the poplar lace bug as a very important pest in the Mediterranean basin, with an increasing potential risk in a global warming scenario

Comparative Analysis of Muscle Transcriptome between Pig Genotypes Identifies Genes and Regulatory Mechanisms Associated to Growth, Fatness and Metabolism.

Iberian ham production includes both purebred (IB) and Duroc-crossbred (IBxDU) Iberian pigs, which show important differences in meat quality and production traits, such as muscle growth and fatness. This experiment was conducted to investigate gene expression differences, transcriptional regulation and genetic polymorphisms that could be associated with the observed phenotypic differences between IB and IBxDU pigs. Nine IB and 10 IBxDU pigs were slaughtered at birth. Morphometric measures and blood samples were obtained and samples from Biceps femoris muscle were employed for compositional and transcriptome analysis by RNA-Seq technology. Phenotypic differences were evident at this early age, including greater body size and weight in IBxDU and greater Biceps femoris intramuscular fat and plasma cholesterol content in IB newborns. We detected 149 differentially expressed genes between IB and IBxDU neonates (p < 0.01 and Fold-Change > 1. 5). Several were related to adipose and muscle tissues development (DLK1, FGF21 or UBC). The functional interpretation of the transcriptomic differences revealed enrichment of functions and pathways related to lipid metabolism in IB and to cellular and muscle growth in IBxDU pigs. Protein catabolism, cholesterol biosynthesis and immune system were functions enriched in both genotypes. We identified transcription factors potentially affecting the observed gene expression differences. Some of them have known functions on adipogenesis (CEBPA, EGRs), lipid metabolism (PPARGC1B) and myogenesis (FOXOs, MEF2D, MYOD1), which suggest a key role in the meat quality differences existing between IB and IBxDU hams. We also identified several polymorphisms showing differential segregation between IB and IBxDU pigs. Among them, non-synonymous variants were detected in several transcription factors as PPARGC1B and TRIM63 genes, which could be associated to altered gene function. Taken together, these results provide information about candidate genes, metabolic pathways and genetic polymorphisms potentially involved in phenotypic differences between IB and IBxDU pigs associated to meat quality and production traits

Delirium en el posoperatorio de una prótesis de rodilla. Diagnóstico del delirium

A 78 year-old male with Parkinson’s disease, who had a scheduled knee prosthesis intervention, presented an acute confusional pattern in the postoperative period associated with morphic and antiparkinsonian medication, with an unexpected fatal outcome. The identification of patients at risk and the precipitating causes of delirium, as well as the introduction of preventive measures are essential to improve mortality and associated complications.Varón de 78 años con enfermedad de Parkinson, intervenido de forma programada de prótesis de rodilla, presenta cuadro confusional agudo en el posoperatorio asociado a mórficos y antiparkinsonianos, con desenlace fatal no esperado. La identificación de los pacientes de riesgo y de las causas precipitantes del delirium, así como la instauración de medidas preventivas, son imprescindibles para mejorar la mortalidad y las complicaciones asociadas

Influence of pH on the adsorption-desorption of doxycycline, enrofloxacin, and sulfamethoxypyridazine in soils with variable surface charge

Financiado para publicación en acceso aberto: Universidade de Vigo/CISUGIn this research, the adsorption/desorption of the antibiotics doxycycline (DC), enrofloxacin (ENR), and sulfamethoxypyradazine (SMP) was studied in 6 agricultural soils with predominance of variable charge, both before and after removing organic matter by calcination. DC adsorption was high at acidic pH, and decreased at pH values above 8. Removal of organic matter with calcination caused just a slight decrease in adsorption, and even in some soils adsorption was similar to that in non-calcined samples. The adsorption coefficients (Kd) were higher for the DC− species compared to DC+, DC0 and DC2−. Regarding DC desorption, the values were very low throughout the pH range covered in the study (2–12), both in the calcined samples and in those not subjected to calcination. ENR showed a similar behavior to DC regarding the effect of pH, since ENR adsorption also decreased at basic pH, but the effect of removing organic matter was different, as it caused a clear decrease in ENR adsorption. The species with the highest Kd was in this case ENR0, although ENR+ is also quantitatively important as regards Kd value in calcined samples. For this antibiotic, no differences in desorption were observed between calcined and non-calcined samples. Finally, SMP adsorption also decreased as pH increased, and, in addition, similarly to what happened with ENR, in general, there was a strong decrease in SMP adsorption when organic matter was removed. The species with the highest Kd in this case was SMP+ in non-calcined samples, but SMP0 and SMP− become more relevant in calcined samples. The percentages of SMP desorption were higher than those for the other two antibiotics, and an increase occurs at intermediate pH values, being higher for calcined samples. These results can be considered relevant in terms of increasing the knowledge as regards the possible evolution and fate of the three antibiotics studied. Specifically, for different pH conditions and with different organic matter contents, when they reach soils and other environmental compartments after being discharged as contaminants. This could have important repercussions on public health and the overall environmentMinisterio de Economía y Competitividad | Ref. CGL2015-67333-C2-1-RMinisterio de Economía y Competitividad | Ref.

Distinción mente y realidad: una tarea de toma de perspectiva conceptual en una población especial

Los niños deben distinguir entre su propio conocimiento o interpretación subjetiva de un hecho y la realidad objetiva. Este estudio, situado en el marco de referencia definido como "toma de perspectiva conceptual", analiza la habilidad de los niños deficientes psíquicos para diferenciar entre la experiencia sensorial "ver" y el estado mental "conocer" derivado de esa experiencia sensorial, debiendo inferir el estado mental de conocimiento de otra persona. Los resultados sugieren que la percepción de la misma información visual puede ser interpretada de diferentes maneras y se dan patrones de respuesta específicos en esta población especial. Por otra parte, esta capacidad es adquirida más tardiamente por estos sujetos que por la población normal y aparece como una variable independiente de la edad mental
