    No full text
    This dataset belongs to the experiment carried out in Sierra Filabres (Almería) to explore the effects of prescribed burns and pyric herbiroy on Mediterranean shrubland communities.  This dataset contains data relative to the comparison between the estimation of plant coverage using a multispectral camera on a Remotely Piloted Aircraft System (RPAS), and the plant coverage estimated using ground-truth methods (traditional way). The dataset includes the total coverage for 96 plots within two areas (two treatments) usging the RPAS and using the traditional method. For each of the 96 several fields are included: date: date of the field and RPAS measures quadrat_name: id of the quadrat. cover_type_infoca: an internal classification of the covert type (not used) plant_coverage_field: the estimated plant coverage by traditional methods.  plant_coverage_rpas: the estimated plant coverage by RPAS.  shannon: the Shannon-Wiener index (plant diversity) richness: number of total plant species per quadrat slope: the terrain slope (in percentage) treatment: the treatmen where the plots were set.  cover_type: the cover type considered in the study.  This experiment belong to the LivingLabs developed in this area to explore the role of pastoralism in the conservation of the biodiversity.  </p

    Agroecological management improves ecosystem services in almond orchards within one year

    There is an increasing body of studies that show that land use intensification and homogenisation in agriculture landscapes, aimed at increasing food provisioning, decline other ecosystem services. Agroecological management has been proposed as an alternative to conventional agricultural management because of its presumed capacity to rehabilitate degraded ecosystem services. In this study we tested whether the agroecological principles of minimum mechanical soil disturbance, maintaining understory cover and application of organic amendments can improve the provisioning of ecosystem services and whether bundles of ecosystem services emerged. We experimentally implemented no-tillage (NT), green manure (GM), compost (CM) and conventional tillage (CT) as a control in five almond orchards in south-eastern Spain and monitored nutrient cycling, carbon stock, habitat provisioning, food provisioning, pest control and pollination after one year. We found that CM and NT had a higher overall ecosystem service performance than CT, and that GM did not differ from CT. The treatments significantly improved ecosystem services such as nutrient cycling, carbon stock, habitat provisioning and food provisioning, but not pest control and pollination. CM treatment resulted in higher soil enzyme activity (glucosidase and phosphatase), soil nutrient content (total N and extractable K), leaf nutrient content (P and K concentrations), soil organic carbon (SOC) content and almond kernel weight compared to other treatments. GM treatment resulted in higher phosphatase activity, understory carbon content and more understory cover than CT. NT treatment resulted in higher glucosidase, phosphatase and urease activity, understory plant diversity and more understory cover than CT. We also found an emerging bundle between SOC and soil enzyme activity and between individual almond weight and soil nutrient levels and SOC. This study shows that ecosystem services can rehabilitate rather quickly, given the one-year time frame of the study. Further, each agroecological practice may enhance a specific set of ecosystem services

    Monitoring data on the effect of domestic livestock and rabbits on Androcymbium europaeum (Lange) K. Richt. and its xerophytiques pastures for thirteen years

    Dataset of annual monitoring of herbivory effects on the conservation status of the endangered species Androcymbium europaeum (Lange) K. Richt and its associated plant communities is presented in this manuscript. This dataset encompasses the annual monitoring of herbivory effects on the conservation status of the endangered species Androcymbium europaeum. Since 2010, the SERPAM Department (Service of Evaluation, Restoration and Protection of Mediterranean Agrosystems) at the Zaidin Experimental Station, belonging to the Spanish National Research Council (CSIC-EEZ), has conducted annual sampling to assess the impact of both domestic and wild livestock, specifically rabbits, on the pastures where A. europaeum lives. The study consisted of a randomised block design, implementing three distinct treatments to evaluate different management strategies: (1) rabbit and domestic herbivory, (2) exclusion of domestic livestock and (3) exclusion of rabbits and domestic livestock. Within each treatment, two types of monitoring were conducted. Firstly, the abundance of A. europaeum was estimated by counting individuals within 50 cm x 50 cm quadrats. Secondly, plant species diversity was assessed along 2-m long transects using the modified Point-Quadrat method. The research was conducted within the Cabo de Gata-Níjar Natural Park in southern Spain, specifically in the Amoladeras Nature Reserve in Almería.The dataset contains information spanning from 2010 to 2023, providing valuable insights into the annual monitoring of herbivory effects on the conservation status of A. europaeum, contributing to our understanding of the species' interaction with domestic and wild animal in the studied area

    Impact of late presentation of HIV infection on short-, mid- and long-term mortality and causes of death in a multicenter national cohort : 2004-2013

    To analyze the impact of late presentation (LP) on overall mortality and causes of death and describe LP trends and risk factors (2004-2013). Cox models and logistic regression were used to analyze data from a nation-wide cohort in Spain. LP is defined as being diagnosed when CD4 < 350 cells/ml or AIDS. Of 7165 new HIV diagnoses, 46.9% (CI:45.7-48.0) were LP, 240 patients died.First-year mortality was the highest (aHR = 10.3[CI:5.5-19.3]); between 1 and 4 years post-diagnosis, aHR = 1.9(1.2-3.0); an
