Generación de un banco de áreas de reflectividad pseudoinvariante para la Península Ibérica mediante imágenes MODIS

La reflectividad derivada de imágenes satelitales sigue generalmente el ciclo fenológico de las cubiertas presentes en el territorio. A pesar de ello, es posible encontrar zonas donde la reflectividad es prácticamente invariante. Estas áreas definidas como pseudoinvariantes (API) permiten comparar y calibrar imágenes provenientes de distintos sensores y procesar series temporales con una elevada coherencia. Se presenta un nuevo método automático (especialmente útil en entornos Big Data) para seleccionar API a partir del producto diario MOD09GA derivado de imágenes Terra-MODIS, utilizando una serie temporal de 14 años y las bandas del espectro solar (visible, infrarrojo cercano y de onda corta) con una resolución espacial de 500 m. Dicha metodología consta de dos etapas de filtrado, una primera que evalúa la calidad de las imágenes de la serie mediante técnicas geoestadísticas, seleccionando las mejores, y una segunda que define umbrales específicos para cada banda espectral, en función de la dispersión que presentan los datos en la selección previa de imágenes. La aplicación de este método sobre ámbitos de características topográficas y estructura de paisaje diferenciados en la Península Ibérica ha permitido la obtención de más de 12 000 API en una superficie asimilable a 9 escenas Landsat (WRS-2). Los resultados muestran que la metodología aplicada contempla la adecuada distribución tanto interanual como intraanual de las imágenes, dando lugar a API que abarcan una amplia variedad de cubiertas con reflectividades diversas, ubicadas principalmente en zonas boscosas o seminaturales (77%),zonas agrícolas (21 %), así como en otros tipos de cubiertas no vegetales

Two different epidemiological scenarios of border disease in the populations of Pyrenean chamois (Rupicapra p. pyrenaica) after the first disease outbreaks

Since 2001 several outbreaks of a new disease associated with Border disease virus (BDV) infection have caused important declines in Pyrenean chamois (Rupicapra pyrenaica) populations in the Pyrenees. The goal of this study was to analyze the post-outbreak BDV epidemiology in the first two areas affected by disease with the aim to establish if the infection has become endemic. We also investigated if BDV infected wild and domestic ruminants sharing habitat with chamois. Unexpectedly, we found different epidemiological scenarios in each population. Since the disease outbreaks, some chamois populations recuperated quickly, while others did not recover as expected. In chamois from the first areas, prevalence was high (73.47%) and constant throughout the whole study period and did not differ between chamois born before and after the BDV outbreak; in all, BDV was detected by RT-PCR in six chamois. In the other areas, prevalence was lower (52.79%) and decreased during the study period; as well, prevalence was significantly lower in chamois born after the disease outbreak. No BDV were detected in this population. A comparative virus neutralisation test performed with four BDV strains and one Bovine viral diarrhoea virus (BVDV) strain showed that all the chamois had BDV-specific antibodies. Pestivirus antibodies were detected in all the rest of analyzed species, with low prevalence values in wild ruminants and moderate values in domestic ruminants. No viruses were detected in these species. These results confirm the hypothesis that outbreaks of BDV infection only affect the Pyrenean chamois, although other wild ruminants can occasionally be infected. In conclusion, two different scenarios have appeared since the first border disease outbreaks in Pyrenean chamois: on the one hand frequent BDV circulation with possible negative impact on population dynamics in some areas and on the other, lack of virus circulation and quick recovery of the chamois population.The PhD studies of LFS are funded by a University Teaching Grant (FPU: Formación de Profesorado Universitario) from the Spanish Ministry of Education (Ministerio de Educación) and ES by the Beatriu de Pinós programme (BP-DGR 2011) of the Catalan Science and Technology System.

Alternativas para la clarificación del jarabe de glucosa obtenido por hidrólisis enzimática del almidón

El presente artículo estudia algunas rutas para la separación y purificación del jarabe de glucosa obtenido por la hidrólisis enzimática del almidón de papa. El proceso de clarificación se realiza en tres etapas. La primera de ellas, la remoción de sólidos, se lleva a cabo con la aplicación de técnicas convencionales de separación de sólido-líquido como la sedimentación, centrifugación y filtración, estudiando, además el efecto de utilizar agentes floculantes y coagulantes, previo a las operaciones ya mencionadas. La segunda etapa, la purificación, se hace con la adición de agentes decolorantes y posterior ultrafiltración del jarabe. Finalmente, la concentración, se efectúa por evaporación al vacío. Los resultados mostraron cómo las técnicas de separación, centrifugación y sedimentación alcanzaron porcentajes del 78% y 98%, respectivamente; en la etapa de purificación se encontró, que los agentes absorbentes como el carbón activado y las tierras diatomáceas son efectivos en la remoción de color. Con lo anterior se logró plantear finalmente la alternativa de separación más adecuada que permitió la obtención de un jarabe con características y propiedades similares al producto comercial. Se presenta además el módulo tecnológico más apropiado para llevar a cabo la operación.The present paper studies some routes for separating and purifying glucose syrup obtained by enzymatic hydrolysis of potato starch. The clarifying process is done in three stages. The first one (solids remotion) is done by applying conventional solid-liquid separation techniiques such as sedimentation, centrifugation and filtration, as well as studying the effect of using flocculant and coagulant agents, prior to the already mentioned operations. Purification is done by adding decolouring agents, followed by ultrafiltration of the syrup. The last step (concentration) is done by vacuum evaporation. The results showed that separation, centrifuging and sedimation reached 50% yield whilst filtration and ultrafiltration achieved 78% and 98% respectively. It was found that adsorbent agents such as activated carbon and diatomaceous earth were effective in removing colour during the purification stage. The most suitable alternative for separation can be suggested from the foregoing, allowing a syrup to be obtained having similar characteristics and propierties to the commercial product. The most appropriate technological module for carrying out the operation is also represented

The role of recent (1985-2014) patterns of land abandonment and environmental factors in the establishment and growth of secondary forests in the Iberian Peninsula

Farmland abandonment has been a widespread land-use change in the Iberian Peninsula since the second half of the 20th century, leading to the establishment of secondary forests across the region. In this study, we aimed to address changes in the recent (1985-2014) emergence patterns of these forests and examine how environmental factors affected their growth by considering differences in leaf-habit types. We used a combination of Landsat-derived land-cover maps and above-ground biomass (AGB) maps from the European Space Agency to assess the secondary forest establishment and growth, respectively, in the study region. We also obtained a set of topographic, climatic and landscape variables from diverse GIS layers and used them for determining changes over time in the environmental drivers of forest establishment and AGB using general linear models. The results highlight that secondary forest cover was still increasing in the Iberian Peninsula at a rate above the European average. Yet, they also indicate a directional change in the emergence of secondary forests towards lower and less steep regions with higher water availability (mean rainfall and SPEI) and less forest cover but are subjected to greater drought events. In addition, these environmental factors differentially affect the growth of forests with different leaf-habit types: i.e., needleleaf secondary forests being less favoured by high temperature and precipitation, and broad-leaf deciduous forests being most negatively affected by drought. Finally, these spatial patterns of forest emergence and the contrasting responses of forest leaf-habits to environmental factors explained the major development of broadleaf evergreen compared to broadleaf deciduous forests and, especially, needleleaf secondary forests. These results will improve the knowledge of forest dynamics that have occurred in the Iberian Peninsula in recent decades and provide an essential tool for understanding the potential effects of climate warming on secondary forest growth

Ten years of local water resource management : Integrating satellite remote sensing and geographical information systems

On 2002, a novel initiative was undertaken by the local water administration of Catalonia (the Agència Catalana de l'Aigua) and the Universitat Autònoma de Barcelona, leading to a ten-year project where a high number of medium resolution satellite images (MODIS and Landsat) were integrated to the daily water management to improve decision making effectiveness. This paper describes the methodology followed in the successful application of remote sensing, as well as the main problems that had to be overcome during its execution. It also presents the products that have been calculated. These are integrated into the Agency's corporate GIS and immediately available via the intranet for the staff, and a selection is available on the Internet
