    Thematic cartography use to be the starting point in several works. It is necessary to be careful with the errors that data source may have to achieve a good outcome. Using a simple methodology we can identify thematic errors in the CORINE Land Cover cartography from the years 2000 and 2006 through the database intersection. That map intersection will give us a group of stable and changing polygons and a cross tabulation matrix with which the surface gain or loss can be interpreted. By means of studies through sampling stable and changing polygons and their verification with orthophotos we can find several thematic errors in the cartography used. Besides, the use of confusion matrices determines the level of global accuracy and categories most prone to error.La cartografía temática suele ser el punto de partida en muchos trabajos. Es necesario tener cuidado con los errores que pueda presentar la fuente de datos para conseguir un buen resultado. Utilizando una sencilla metodología se pueden determinar errores temáticos en las cartografías CORINE Land Cover de los años 2000 y 2006 a través de la intersección de ambas bases de datos. Dicha intersección de mapas nos dará una serie de polígonos estables y de cambio y una matriz de cruce con la que interpretar el balance de superficie ganada o perdida. Mediante el estudio a través de muestreos de los diferentes tipos de cambio y su verificación con ortofotos se puede llegar a encontrar diversos errores de asignación temática en las cartografías empleadas. Además, el uso de las matrices de confusión permite establecer el nivel de exactitud global y de las categorías más propensas a errores.

    Climate warming triggers the emergence of native viruses in Iberian amphibians

    Get PDF
    The number of epizootics in amphibian populations caused by viruses of the genus Ranavirus is increasing worldwide. Yet, causes for pathogen emergence are poorly understood. Here, we confirmed that the Common midwife toad virus (CMTV) and Frog virus 3 (FV3) are responsible for mass mortalities in Iberia since the late 1980s. Our results illustrate the Iberian Peninsula as a diversity hotspot for the highly virulent CMTV. Although this pattern of diversity in Europe is consistent with spread by natural dispersal, the exact origin of the emergence of CMTV remains uncertain. Nevertheless, our data allow hypothesizing that the Iberian Peninsula might harbor the ancestral population of CMTVs that could have spread into the rest of Europe. In addition, we found that climate warming could be triggering the CMTV outbreaks, supporting its endemic status in the Iberian Peninsula.info:eu-repo/semantics/acceptedVersio

    INTRODUCTION We analyze the activities carried out by primary care (PC) physicians and nurses with respect to smoking cessation and evaluate their self-reported training, knowledge, and behavior. METHODS A cross-sectional study was conducted including 1514 PC physicians and nurses from June 2016 to March 2017, in Spain. The main variable was Good Practice (GP) in attention to smokers. To identify associated factors, a multilevel logistic regression model was used adjusted for sex, age, type of center, contract, years of employment, tobacco consumption, and self-reported training/knowledge. RESULTS Of the 792 physicians and 722 nurses, 48.6% referred to GP in smoking cessation management. The finding related to: being a non-smoker (OR=1.8; 95% CI: 1.2-2.5) or ex-smoker (OR= 1.4; 95% CI: 1.02-2.1), having a good level of knowledge (OR=1.8; 95% CI: 1.3-2.4) and training (OR=2.4; 95% CI: 1.8-3.2), and, to a lesser extent, being female (OR=1.3; 95% CI: 1.03-1.7), and work experience >10 years (OR=1.4; 95% CI: 1.03-1.9). The main GP barriers were: lack of time (45.5%), organizational problems (48.4%), and 35.4% lack of training. CONCLUSIONS The GP of PC physicians and nurses regarding smoking cessation management is related to being non-smokers or ex-smokers, and having sufficient training and knowledge. Lack of time and organizational problems were considered to be the main barriers. The promotion of training activities in the Spanish National Health Service with the support of scientific societies is required

    Land-use changes and biodiversity conservation in agricultural landscapes. A case study

    Get PDF
    A wide range of global biodiversity is concentrated in rural landscapes. Indeed, many wild species and natural habitats are directly or indirectly associated with agricultural systems. In turn, some genomes of wild species can contribute, on one hand, to agricultural productivity and quality and, on the other, to ongoing biological control of crop-specific pests. Thus, management of these landscapes should consider applying agricultural practices adapted to biodiversity conservation, which will also result in enhanced production levels. One way to infer the state of conservation of biodiversity in rural landscapes is through knowledge of their spatial structure, i.e., the configuration and composition of different land uses and remnant natural vegetation. This knowledge can serve to evaluate the behavior of the ecological processes associated with the above mentioned structure and to assess the integrity of the landscape and its potential biodiversity. The current spatial pattern of the landscape is the result of changes in land uses and management practices therein throughout time, essentially as a result of socioeconomic changes. Study of these changes enables us to propose future scenarios based upon the design and implementation of management policies that consider the history of the aforementioned changes Moreover, it is interesting to note the growing interest of agricultural policies, at different levels (for example, the Common Agriculture Policy at European level), in ecological compensation measures for agricultural areas (specific subsidies) involving conservation and improvement of biodiversity. The receiving of certain subsidies depends on the correct application of feasible agro-environmental models. In this sense, spatial analysis of the landscape and changes therein can be useful for more effective conservation of biodiversity while maintaining an optimum level of productivity, which can be seen in the diverse models applied in different regions. The present study, conducted in Andalusia in southern Spain,consisted of analysing the structure of a rural landscape of olive groves, as well as the dynamics of change in land uses and land cover over a period of 50 years. The study results show a trend towards intensification of olive cultivation (mainly irrigation and increased energy inputs), a greater area occupied by these crops and maintenance of the area covered by natural vegetation and even an increase therein. As a result of these processes, the landscape has maintained an acceptable level of connectivity,diversity of land uses and spatial heterogeneity.This situation enabled us to infer a good situation for biodiversity conservation and for the potential restoration of the rural landscape studied. Our results highlight the need for an agro-environmental model at landscape-scale for the conservation of biodiversity and maintenance of a reasonable level of profitable productivity. We therefore recommend the abandonment of less productive farmland and a spatial landscape configuration based upon the ‘land sparing’ alternative. This alternative involves the persistence of remnants of useful native vegetation such as:natural or semi-natural habitats (essential for species specialised in agricultural systems); discontinuous corridors (stepping stones) and the potential restoration of native vegetation.This study was supported by the research project of the National Plan (R + D + i) of the Government of Spain (CSO2009-08154 2010/2013, PI Sanz-Cañada, J): Territorial Externalities in local agro-food systems: rural development, landscapes and public goods in olive oil designations of origin (EXTERSIAL).Peer reviewe
