Forest resilience to global warming is strongly modulated by local-scale topographic, microclimatic and biotic conditions

Resilience of endangered rear edge populations of cold-adapted forests in the Mediterranean basin is increasingly altered by extreme heatwave and drought pressures. It remains unknown, however, whether microclimatic variation in these isolated forests could ultimately result in large intra-population variability in the demographic responses, allowing the coexistence of contrasting declining and resilient trends across small topographic gradients. Multiple key drivers promoting spatial variability in the resilience of rear edge forests remain largely unassessed, including amplified and buffered thermal exposure induced by heatwaves along topographic gradients, and increased herbivory pressure on tree saplings in defaunated areas lacking efficient apex predators. Here we analysed whether indicators of forest resilience to global warming are strongly modulated by local-scale topographic, microclimatic and biotic conditions. We studied a protected rear edge forest of sessile oak Quercus petraea, applying a suite of 20 indicators of resilience of tree secondary growth, including multidecadal and short-term indices. We also analysed sapling recruitment success, recruit/adult ratios and sapling thermal exposure across topographic gradients. We found large within population variation in secondary growth resilience, in recruitment success and in thermal exposure of tree saplings to heatwaves, and this variability was spatially structured along small-scale topographical gradients. Multidecadal resilience indices and curves provide useful descriptors of forest vulnerability to climate warming, complementing assessments based in the analysis of short-term resilience indicators. Species-specific associations of trees with microclimatic variability are reported. Biotic factors are key in determining long-term resilience in climatically stressed rear edge forests, with strong limitation of sapling recruitment by increased roe deer and wild boar herbivory. Our results also support non-stationary effects of climate determining forest growth responses and resilience, showing increased negative effects of warming and drought over the last decades in declining stands. Synthesis. Our findings do not support scenarios predicting spatially homogeneous distributional shifts and limited resilience in rear edge populations, and are more supportive of scenarios including spatially heterogeneous responses, characterised with contrasting intra-population trends of forest resilience. We conclude that forest resilience responses to climate warming are strongly modulated by local-scale microclimatic, topographic and biotic factors. Accurate predictions of forest responses to changes in climate would therefore largely benefit from the integration of local-scale abiotic and biotic factors

Impacts of use and abuse of nature in Catalona with proposal for sustainable management

This paper provides an overview of the last 40 years of use, and in many cases abuse, of the natural resources in Catalonia, a country that is representative of European countries in general, and especially those in the Mediterranean region. It analyses the use of natural resources made by mining, agriculture, livestock, logging, fishing, nature tourism, and energy production and consumption. This use results in an ecological footprint, i.e., the productive land and sea surface required to generate the consumed resources and absorb the resulting waste, which is about seven times the amount available, a very high number but very similar to other European countries. This overexploitation of natural resources has a huge impact on land and its different forms of cover, air, and water. For the last 25 years, forests and urban areas have each gained almost 3% more of the territory at the expense of agricultural land; those municipalities bordering the sea have increased their number of inhabitants and activity, and although they only occupy 6.7% of the total surface area, they account for 43.3% of the population; air quality has stabilized since the turn of the century, and there has been some improvement in the state of aquatic ecosystems, but still only 36% are in good condition, while the remainder have suffered morphological changes and different forms of nonpoint source pollution; meanwhile the biodiversity of flora and fauna remains still under threat. Environmental policies do not go far enough so there is a need for revision of the legislation related to environmental impact and the protection of natural areas, flora, and fauna. The promotion of environmental research must be accompanied by environmental education to foster a society which is more knowledgeable, has more control and influence over the decisions that deeply affect it. Indeed, nature conservation goes hand in hand with other social and economic challenges that require a more sustainable vision. Today's problems with nature derive from the current economic model, which is environmentally unsustainable in that it does not take into account environmental impacts. Lastly, we propose a series of reasonable and feasible priority measures and actions related to each use made of the country's natural resources, to the impacts they have had, and to their management, in the hope that these can contribute to improving the conservation and management of the environment and biodiversity and move towards sustainability

Els treballs de fi de grau a la Universitat de Barcelona

Podeu consultar la versió castellana al camp recurs relacionat.La implantació dels títols de grau ha suposat un repte per a les universitats, que han hagut d'adaptar els seus projectes formatius a les directrius de l’Espai Europeu d’Educació Superior. Un dels aspectes importants d’aquest procés ha estat l'obligació d’incorporar els treballs de fi de grau (TFG) a l’estructura curricular dels plans d’estudis. Aquesta tasca ha estat complexa i, a més, s’ha vist dificultada per la poca tradició que la majoria de facultats i escoles universitàries tenien en el disseny, l'organització i l'avaluació d’aquest tipus de treball. Uns quants cursos després d’haver-se posat en marxa els TFG, l’Institut de Ciències de l’Educació (ICE) de la Universitat de Barcelona va voler oferir als diferents centres de la UB una plataforma de reflexió i debat on poguessin compartir experiències, plantejar dubtes, analitzar models de bones pràctiques i recollir idees per millorar els seus projectes. A tal efecte, des de la Secció d’Universitat de l’ICE, es va organitzar la jornada «Els treballs de fi de grau a la UB». Aquest quadern recull les comunicacions presentades, sintetitza el debat que van generar i presenta les conclusions a què es va arribar

Els TFG de la Facultat de Biologia 10 anys després de Boloya. Adequant l'avaluació a la situació actual: La diversitat de TFG requereix diversitat de rúbriques

Codi del projecte: 2019PID-UB/035La experiència adquirida després de 10 anys de la implantació del model de Pràcticums i Treball Fi de Grau (TFG) a la Facultat de Biologia ha permès identificar diferents tipologies de projectes. L’actuació realitzada en aquest projecte contempla la incorporació en els TFGs d’un nou apartat que inclou la reflexió crítica dels estudiants sobre la contribució del seu projecte als Objectius del Desenvolupament Sostenible (ODS). Aquesta acció permet visualitzar els ODS i impulsar-los seguint les directrius de l’Agenda 2030 de la UB. Així, s’han generat dos productes que ja estat implementats i operatius des del curs 21-22. El primer producte consisteix en unes noves rúbriques que han adequat els ítems i continguts a la diversitat de tipologies de TFG que es realitzen a la Facultat de Biologia, incloent l’avaluació adaptada a la metodologies Aps. Aquestes rubriques també incorporen una nova dimensió avaluable sobre la contribució de cada treball de fi de grau als ODS a partir de la reflexió crítica realitzada per l’estudiantat en el seu TFG. El segon producte és la elaboració i difusió d’una guia de suport per a estudiants i tutors per a la incorporació dels ODS als treballs fi de grau. Aquesta guia ha estat incorporada al full de ruta de sostenibilitat de la UB per la seva distribució als diferents centres de la UB per tal d’incorporar aquesta activitat reflexiva a tots els treballs de fi de grau de la UB.Programa RIMD

Knowledge, attitudes, behavioral and organizational factors of health professions students for a competent smoking cessation practice: An instrument adaptation and psychometric validation study in Spanish and English samples

Background: To improve smoking cessation, training of health professions students is essential. However, no specific instrument is available to assess factors that may affect students' learning about smoking cessation practice. Aim: To adapt and validate the Knowledge, Attitudes, Behaviors and Organization questionnaire in the population of undergraduate health professions students. Design: Methodological research. Methods: The researchers conducted this study with 511 Spanish and 186 English health professions students from four different universities. We used a four-step approach: 1) adaptation of the items to the target population and validation of the content by a panel of experts; 2) a pilot study to test face validity; 3) linguistic adaptation of the Spanish version to English; and 4) the psychometric assessment based on construct validity, criterion validity and internal consistency. Results: Exploratory factor analysis revealed four subscales for the Spanish version, namely ‘Individual knowledge and skills’, ‘Individual attitudes and beliefs’, ‘Organizational support’ and ‘Organizational resources’, which accounted for 85.1% of the variance. Confirmatory factor analysis in the holdout Spanish and English samples revealed adequate goodness-of-fit values, supporting the factor structure. Hypotheses testing demonstrated significant differences by capacitation in smoking cessation interventions and degree courses, providing further evidence regarding construct validity. All the subscales correlated positively with the criterion variables (5 A’s smoking cessation model), except for the ‘Organizational resources’ subscale, which was not significantly correlated with the 5 A's. The overall Cronbach’s alpha was.83 for the Spanish version and.88 for the English one. Conclusions: Our results provide empirical support for the use of the Knowledge, Attitudes, Behaviors and Organization questionnaire for Students as a reliable and valid instrument to assess knowledge, attitudes, behaviors and organization perceptions in health professions students, which is essential for competent smoking cessation practice. Interestingly, ‘Organizational resources’ subscale presented the lowest correlations among factors and did not correlate with any component of the 5 A's, suggesting the need of enhancing students' responsibility and involvement during their internships, as well as the interest of some organizations

Los trabajos de fin de grado en la Universidad de Barcelona

Podeu consultar la versió catalana al camp recurs relacionat.[spa] La implantación de los títulos de grado ha supuesto un reto para las universidades, que han tenido que adaptar sus proyectos formativos a las directrices del Espacio Europeo de Educación Superior.

Esta tarea ha sido compleja y, además, se ha visto dificultada por la poca tradición que la mayoría de facultades y escuelas universitarias tenían en el diseño, organización y evaluación de esta clase de trabajo. Después de varios cursos de haberse puesto en marcha los TFG, el Instituto de Ciencias de la Educación (ICE) de la Universidad de Barcelona quiso ofrecer a los diferentes centros de la UB una plataforma de reflexión y debate donde pudieran compartir experiencias, plantear dudas, analizar modelos de buenas prácticas y recoger ideas para mejorar sus proyectos. A tal efecto, desde la Sección de Universidad del ICE se organizó la jornada «Los trabajos de fin de grado en la UB». Este cuaderno recoge las comunicaciones presentadas, sintetiza el debate que generaron y presenta las conclusiones a que se llegó.[eng] The phase-in of undergraduate degrees conforming to the guidelines of the European Higher Education Area has been a challenge for universities as far as their training projects are concerned. An important aspect of this process was the need to incorporate the Bachelor’s Degree Final Project (TFG) to the structure of their curricula. This task has been complex and been hampered also by the lack of tradition that most faculties and university colleges had in the design, organization and evaluation of these types of project. Several years after launching the TFG, the Institute of Education Sciences (ICE) of the University of Barcelona (UB) organized the «The Bachelor’s Degree Final Project» conference to offer different centres of the UB a space for reflection and debate to be able to share experiences, ask questions, analyse models of good practices and gather ideas for improving their projects. The present booklet includes papers, summarizes the debate that many and varied contributions generated and outlines the final conclusions reached at this conference

Early life risk factors and their cumulative effects as predictors of overweight in Spanish children

Objectives: To explore early life risk factors of overweight/obesity at age 6 years and their cumulative effects on overweight/obesity at ages 2, 4 and 6 years. Methods: Altogether 1031 Spanish children were evaluated at birth and during a 6-year follow-up. Early life risk factors included: parental overweight/obesity, parental origin/ethnicity, maternal smoking during pregnancy, gestational weight gain, gestational age, birth weight, caesarean section, breastfeeding practices and rapid infant weight gain collected via hospital records. Cumulative effects were assessed by adding up those early risk factors that significantly increased the risk of overweight/obesity. We conducted binary logistic regression models. Results: Rapid infant weight gain (OR 2.29, 99% CI 1.54–3.42), maternal overweight/obesity (OR 1.93, 99% CI 1.27–2.92), paternal overweight/obesity (OR 2.17, 99% CI 1.44–3.28), Latin American/Roma origin (OR 3.20, 99% CI 1.60–6.39) and smoking during pregnancy (OR 1.61, 99% CI 1.01–2.59) remained significant after adjusting for confounders. A higher number of early life risk factors accumulated was associated with overweight/obesity at age 6 years but not at age 2 and 4 years. Conclusions: Rapid infant weight gain, parental overweight/obesity, maternal smoking and origin/ethnicity predict childhood overweight/obesity and present cumulative effects. Monitoring children with rapid weight gain and supporting a healthy parental weight are important for childhood obesity prevention

Effectiveness of an mHealth intervention combining a smartphone app and smart band on body composition in an overweight and obese population: Randomized controlled trial (EVIDENT 3 study)

Background: Mobile health (mHealth) is currently among the supporting elements that may contribute to an improvement in health markers by helping people adopt healthier lifestyles. mHealth interventions have been widely reported to achieve greater weight loss than other approaches, but their effect on body composition remains unclear. Objective: This study aimed to assess the short-term (3 months) effectiveness of a mobile app and a smart band for losing weight and changing body composition in sedentary Spanish adults who are overweight or obese. Methods: A randomized controlled, multicenter clinical trial was conducted involving the participation of 440 subjects from primary care centers, with 231 subjects in the intervention group (IG; counselling with smartphone app and smart band) and 209 in the control group (CG; counselling only). Both groups were counselled about healthy diet and physical activity. For the 3-month intervention period, the IG was trained to use a smartphone app that involved self-monitoring and tailored feedback, as well as a smart band that recorded daily physical activity (Mi Band 2, Xiaomi). Body composition was measured using the InBody 230 bioimpedance device (InBody Co., Ltd), and physical activity was measured using the International Physical Activity Questionnaire. Results: The mHealth intervention produced a greater loss of body weight (–1.97 kg, 95% CI –2.39 to –1.54) relative to standard counselling at 3 months (–1.13 kg, 95% CI –1.56 to –0.69). Comparing groups, the IG achieved a weight loss of 0.84 kg more than the CG at 3 months. The IG showed a decrease in body fat mass (BFM; –1.84 kg, 95% CI –2.48 to –1.20), percentage of body fat (PBF; –1.22%, 95% CI –1.82% to 0.62%), and BMI (–0.77 kg/m2, 95% CI –0.96 to 0.57). No significant changes were observed in any of these parameters in men; among women, there was a significant decrease in BMI in the IG compared with the CG. When subjects were grouped according to baseline BMI, the overweight group experienced a change in BFM of –1.18 kg (95% CI –2.30 to –0.06) and BMI of –0.47 kg/m2 (95% CI –0.80 to –0.13), whereas the obese group only experienced a change in BMI of –0.53 kg/m2 (95% CI –0.86 to –0.19). When the data were analyzed according to physical activity, the moderate-vigorous physical activity group showed significant changes in BFM of –1.03 kg (95% CI –1.74 to –0.33), PBF of –0.76% (95% CI –1.32% to –0.20%), and BMI of –0.5 kg/m2 (95% CI –0.83 to –0.19). Conclusions: The results from this multicenter, randomized controlled clinical trial study show that compared with standard counselling alone, adding a self-reported app and a smart band obtained beneficial results in terms of weight loss and a reduction in BFM and PBF in female subjects with a BMI less than 30 kg/m2 and a moderate-vigorous physical activity level. Nevertheless, further studies are needed to ensure that this profile benefits more than others from this intervention and to investigate modifications of this intervention to achieve a global effect

Se estableció la necesidad de desarrollar un Programa de Atención al Ictus (PAIA). Material y métodos Damos a conocer la dinámica de planificación, implantación, evaluación y mejora que se ha desarrollado entre los años 2009-2014 y sus resultados a 5 años. Resultados Se ha mejorado en la estructura, en los procesos y en los resultados, con mejoría en los indicadores clave de la asistencia (audit 2008-2010-2012) y otros: tasa ictus 2013: 2, 07 (2008: 2, 36); 78% ictus atendidos en áreas/unidades en 2014 (30%, 2008); tasa fibrinólisis 8, 3% en 2014 (4, 4%, 2010); fibrinólisis hospitales secundarios (30% total); fibrinólisis con teleictus 9%; descenso de la mortalidad por ictus, 38%; años de vida prematura perdidos 67, 7 (2013)/144 (2008); capacitación de enfermería, desarrollo de la neurosonología, trabajo en red, con protocolos y buenas prácticas compartidos entre sectores sanitarios, etc. Conclusiones La gestión por procesos y equipos multidisciplinares desplegados en una distribución territorial integral, con protocolos y referencias establecidas y una dinámica de evaluación y mejora continua, ha demostrado ser una herramienta potente para garantizar la calidad y la equidad. El PAIA, por su dinámica de mejora sostenida y la implicación de los clínicos, es un buen ejemplo de gestión clínica y trabajo en red. Introduction: In 2008, stroke mortality, morbidity, and disability rates in Aragon were higher than the average in Spain. These data underscored the need to develop a stroke care programme (PAIA). Material and methods: We present the dynamics of planning, implementation, evaluation, and improvement developed between 2009 and 2014 as well as the results of the PAIA after that 5-year period. Results: Structure, processes, and outcomes have improved with reference to the key indicators of healthcare (audit: 2008, 2010, 2012) among others: stroke rate in 2013 was 2.07 (2.36 in 2008); 78% of strokes were managed in stroke units in 2014 (30% in 2008); rate of fibrinolysis was 8.3% in 2014 (4.4% in 2010); fibrinolysis was administered in secondary hospitals (30% of the total); fibrinolysis was administered by Telestroke in 9%; stroke mortality decreased (38%); 67.7 years of potential life lost (YPLL) in 2013 (144 in 2008); nurse training; development of neurosonology; networking; sharing protocols and best practices between health sectors, etc. Conclusions: Integrated process management and multidisciplinary teams distributed and deployed over an entire territory with established protocols, references, evaluations, and continuous development, have been proven powerful tools to ensure both quality and equality. The PAIA is a good example of clinical governance and networking due to its dynamic and sustained improvement and cooperation between clinicians
