    The map of biodiversity : from local to global scales

    Species richness is not homogeneous in space and it normally presents differences when comparing among different sites. These differences often respond to gradients in one or several factors which create biodiversity patterns in space and are scale-dependent. At a local scale, diversity patterns depend on the habitat size (species-area relationship), the productivity, the environmental harshness, the frequency and intensity of disturbance, or the regional species pool. Regional diversity may be influenced by environmental heterogeneity (increasing dissimilarity), although it could act also at smaller or larger spatial scales, and the connectivity among habitats. Finally, at a global scale, diversity patterns are found with the latitude, the altitude or the depth, although these factors are surrogates for one or several environmental variables (productivity, area, isolation, or harshness)

    The zooplankton of eight restored peridunal ponds located in L' Albufera Natural Park (Valencia, Spain) was sampled fort­nightly from November 2006 to July 2007 to study the effect of hydroperiod, restoration and other environmental variables in the zooplankton community structure. Ponds with different hydroperiods were selected: two permanent ponds, two temporary ponds with a long hydroperiod (> 6 months ayear) and four temporary ponds with short hydroperiod « 6 months). The time since they were restored was also different: two ofthem were only modified; some were restored in the 1990s, and others were regenerated in recent years (2004-05). The results showed great heterogeneity in the zooplankton community, most probably due to the strong differences in some limnological variables (mainly conductivity and depth). The dominant group, in terms of density, were the copepods in four ponds, mainly because the high densities of nauplii and copepodites; the rotifers in three; and cladocerans only in one pond. However, the rotifers presented the highest cumulative richness in all the systems. Species richness in the permanent ponds was higher than in the temporary ones. The main environmental variables affecting the community composition were depth, highly related to permanence of water, restoration time and conductivityEl zooplancton de ocho charcas peridunares del Parque Natural de L'Albufera (Valencia, España) se siguió quincenalmente desde Noviembre 2006 a Julio 2007 para conocer el efecto del hidroperiodo, de la restauración y de otras variables am­bientales en la estructura de la comunidad zooplanctónica. Se estudiaron dos charcas permanentes; dos temporales con hidroperiodo largo (> 6 meses al año); y cuatro con hidroperiodo corto (< 6 meses). También diferían en el año en que fueron restauradas: dos de ellas existían previamente y fueron parcialmente modificadas, algunas fueron restauradas en los 90's, y otras fueron regeneradas más recientemente (2004-05). Los resultados muestran una gran heterogeneidad en la comunidad de zooplancton debido probablemente a las grandes diferencias en las variables limnológicas, principalmente la profundidad y conductividad. El grupo dominante (en densidad)fueron los copépodos en cuatro de los sistemas, debido a la alta densidad de los nauplios y copepoditos, los rotíferos en tres charcas, y los cladóceros solo en una. Pero en todas las charcas, los rotíferos presentaron la mayor riqueza acumulada. Las principales variables ambientales en la composición de la comunidad fueron la profundidad, muy relacionada con la permanencia del agua, la restauración y la conductividad, ya que en las charcas permanentes la riqueza específica fue mayor que en las temporales

    La disfagia es un trastorno de la deglución que presenta una gran prevalencia entre los mayores de 65 años. Afecta significativamente a la salud de los pacientes ya que produce graves complicaciones, sin embargo, está poco reconocida y valorada por el personal sanitario. Para evitar estas complicaciones, es muy importante la realización de un diagnostico precoz y un abordaje adecuado del tratamiento por parte del personal de enfermería.<br /

    Climate Preferences for Tourism: Perceptions Regarding Ideal and Unfavourable Conditions for Hiking in Spain

    Get PDF
    Physical activity is an increasingly frequent part of our leisure time. Within this context, hiking is a popular form of tourism which has a positive impact on the quality of life. In spite of the importance of climate conditions for this recreational activity, relatively little research has been done on hiking from the perspective of climate and tourism. With this in mind in this paper we make the first detailed extensive assessment of climate preferences for the practice of hiking tourism in Spain. To this end a review of the theoretical/methodological body of literature on tourism climatology was conducted together with a survey aimed at evaluating the stated climate preferences of hiking tourists. The results are offered within the framework of international research on climate preferences for a range of tourism activities. The comparative analysis of these results with regard to those obtained in previous research highlights various similarities but also certain factors specific to hiking in Spain. Overall, the climate preferences of hiking tourists are similar to those of other segments of the tourism market in terms of the aesthetic and physical aspects of the climate, although they also have certain specific preferences as regards thermal aspects, especially regarding the optimal daily thermal conditions for hiking. The results obtained are useful for assessing the suitability of the climate for the practice of hiking tourism in Spain and for promoting proper management and planning of this leisure activity in tourist destinations, including the development of climate calendars detailing the most suitable times of the year for hiking at these destinations. These issues will be addressed in future research studies.This research has been conducted within the framework of the R+D+i project with reference number CSO2017-88935-R (funded as part of the Spanish National R&D&I Plan of the Spanish Ministerio de Economía y Competitividad) and with the support of the research groups 2017 SGR 25 (Grup de Recerca Consolidat Territori, Turisme, Canvi Climàtic) and SEJ170 (Paisaje, Planificación Territorial y Desarrollo Local)

    Objective: To determine the degree of psychological distress and fear of COVID-19 experienced by undergraduate student nurses who were about to begin their clinical placements. Method: A cross-sectional study was carried out with 100 second- and third-year undergraduate student nurses of the University of Zaragoza (Spain). Measures included the Fear of COVID-19 Scale and the Depression Anxiety Stress Scales. Results: Regularly, student nurses did not think of themselves as vulnerable to COVID-19. However, a significant association was observed between the student nurses’ level of psychological distress and cohabiting with relatives or people who were considered vulnerable to the infection (p = 0.035). The Depression Anxiety Stress Scale results revealed a low level of psychological distress in general; the Fear of COVID-19 Scale indicated moderate fear (2.94). Conclusion: Student nurses who lived with their relatives experienced higher levels of stress due to the perceived risk of transmission, but were less fearful of loss of work and income. Anxiety in our sample was associated principally with not knowing their upcoming placement location

    Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality
