La Revitalización urbanística de los destinos turísticos del litoral: Una alternativa para los municipios turísticos mediterráneos valencianos.

The municipalities of the Valencian Mediterranean coast increased their urban area due to the irruption of tourism in the middle of the XX century. Despite the initial advantages, the problems that have arisen over the urban space, due to the tourism development model used, lead them towards a progressive loss of tourist attraction during their different stages of evolution. Given this circumstance, it is necessary to intervene on the urban space, not only to renew the tourist destination but also to correct the urban problems generated during the last decades in some municipalities that subordinated their decisions exclusively to the tourist needs. A viable and more sustainable option, in the medium and long term, implies changing the development model, taking as a reference the characteristics of the traditional city. However, the viability and the degree of achievement of this transformation will be based on the particularities of the existing urban space in each case. Results will be based on the city model (Public or Domestic) used as reference for its development and on the urban characteristics (Compact, Mixed or Dispersed) that are specific to it

From a Conceptual Model to a Knowledge Graph for Genomic Datasets

Data access at genomic repositories is problematic, as data is described by heterogeneous and hardly comparable metadata. We previously introduced a unified conceptual schema, collected metadata in a single repository and provided classical search methods upon them. We here propose a new paradigm to support semantic search of integrated genomic metadata, based on the Genomic Knowledge Graph, a semantic graph of genomic terms and concepts, which combines the original information provided by each source with curated terminological content from specialized ontologies. Commercial knowledge-assisted search is designed for transparently supporting keyword-based search without explaining inferences; in biology, inference understanding is instead critical. For this reason, we propose a graph-based visual search for data exploration; some expert users can navigate the semantic graph along the conceptual schema, enriched with simple forms of homonyms and term hierarchies, thus understanding the semantic reasoning behind query results

Demografía y crecimiento primario durante la regeneración de tres especies de pino a lo largo de gradientes climáticos

13 páginas, 4 figuras y 3 tablasLa regeneración es un proceso crítico en la dinámica de los bosques, que presenta una marcada heterogeneidad temporal y espacial. En este trabajo se pretende avanzar en el conocimiento de las variables bióticas y abióticas que determinan a escala local la presencia, abundancia y crecimiento primario de plántulas de tres especies de pino: Pinus sylvestris, P. nigra y P. uncinata, y determinar el efecto relativo del clima. Para ello se muestrearon 216 parcelas distribuidas a lo largo de gradientes climáticos en siete localidades montañosas. Se censaron las plántulas recién emergidas y el resto de juveniles, y se midieron los crecimientos anuales. Los resultados mostraron diferencias significativas entre especies con efectos directos e indirectos del clima sobre la demografía y el estado de los juveniles. En las tres especies se apreció que la supervivencia de los juveniles aparecía desplazada hacia altitudes mayores respecto donde se producía el óptimo de la emergencia. Las relaciones locales de competencia y facilitación ejercieron efectos importantes sobre la regeneración de las tres especies, siendo éstos modulados por el clima.Ministerio Español de Innovación y Ciencia Consolider-Montes (CSD2008_00040), Los autores agradecen a toda la gente que hizo posible el trabajo de campo: R.

Planeamiento territorial sostenible: un reto para el futuro de nuestras sociedades; criterios aplicados

In a large part of the 17 sustainable development objectives set as goals for humanity by the UN, sustainability can be glimpsed. As a result of the dominant socio-productive model, the only way to head towards more sustainable territories that allow achieving and maintaining the well-being of the world's population is to bear in mind the need to properly plan territorial development. This work reflects on this need and takes a step forward in the definition of the main criteria to achieve territorial sustainability at regional and local scales

Is salinity the main ecologic factor that shapes the distribution of two endemic Mediterranean plant species of the genus Gypsophila?

The final publication is available at Springer via http://dx.doi.org/10.1007/s11104-014-2218-2Aims Responses to salt stress of two Gypsophila species that share territory, but with different ecological optima and distribution ranges, were analysed. G. struthium is a regionally dominant Iberian endemic gypsophyte, whereas G. tomentosa is a narrow endemic reported as halophyte. Theworking hypothesis is that salt tolerance shapes the presence of these species in their specific habitats. Methods Taking a multidisciplinary approach, we assessed the soil characteristics and vegetation structure at the sampling site, seed germination and seedling development, growth and flowering, synthesis of proline and cation accumulation under artificial conditions of increasing salt stress and effect of PEG on germination and seedling development. Results Soil salinity was low at the all sampling points where the two species grow, but moisture was higher in the area of G. tomentosa. Differences were found in the species salt and drought tolerance. The different parameters tested did not show a clear pattern indicating the main role of salt tolerance in plant distribution. Conclusions G. tomentosa cannot be considered a true halophyte as previously reported because it is unable to complete its life cycle under salinity. The presence of G. tomentosa in habitats bordering salt marshes is a strategy to avoid plant competition and extreme water stressSoriano, P.; Moruno Manchón, JF.; Boscaiu Neagu, MT.; Vicente Meana, Ó.; Hurtado, A.; Llinares Palacios, JV.; Estrelles, E.

Plant Production Protocols from Seeds of Threatened <i>Atropa baetica</i> and Widespread <i>A. belladonna</i>, Both Rich in Alkaloids

Members of the genus Atropa contain various tropane alkaloids, including atropine ((±)-hyoscyamine) and scopolamine, which possess medicinal properties. Preserving the diverse genetic background of wild populations via optimal plant production from seeds could be essential for avoiding the loss of potential uses. We analyzed the germination ecology of two Atropa species comprising the threatened A. baetica and widespread A. belladonna to determine the: (1) influence of temperature, light, and seed age on germination patterns; (2) effects of cold stratification and gibberellic acid (GA3); (3) phenology of seedling emergence in outdoor conditions; (4) phenology of dormancy break and loss of viability in buried seeds; and (5) ability to form persistent soil seed banks. Freshly matured seeds exhibited conditional physiological dormancy, with germination at high temperatures (32/18 °C) but not at low and cold ones (5, 15/4, 20/7 °C). The germination ability increased with time of dry storage and with GA3, thereby suggesting nondeep physiological dormancy. Under outdoor conditions, no seedlings emerged during the first post-sown autumn, but emergence peaks occurred in late winter–early spring. Both species could form small persistent soil seed banks with short durations (3–5 years). A plant production protocol from seeds was established for both taxa

Presencia de especies del género "Cistus" L. ("Cistaceae") en el anco de semillas del suelo en el pastizal de la raña del Parque Nacional de Cabañeros

Se analizó la presencia de especies del género Cistus en el banco de semillas del suelo en el pastizal que ocupa la raña central del Parque Nacional de Cabañeros ; estas especies son integrantes típicas de la vegetación que antaño se asentaba en la zona. El estudio se llevó a cabo en dos etapas: en la primera se evaluó el banco de semillas completo entre los 0-100 m desde el límite del pastizal con el monte hacia el interior de dicha formación, y en la segunda se evaluó exclusivamente el banco de semillas de cistáceas leñosas, entre los 100 y 300 m de distancia al borde. Se detectó la presencia de un banco persistente de larga duración de Cistus ladanifer y C. salvifolius (738 semillas / metro cuadrado a 0-10 cm de profundidad) altamente viable y aletargado, cuya distribución en la raña fue al azar. Se discuten las consecuencias que la existencia de dicha reserva de semillas podría tener en el manejo del pastizal

Efectos del clima y factores locales sobre la regeneración de cinco especies arbóreas en gradientes altitudinales mediterráneos

El estudio de especies a lo largo de gradientes altitudinales permite explorar las respuestas potenciales de una misma población a escenarios climáticos diferentes. En este trabajo se ha analizado la regeneración de especies arbóreas en gradientes altitudinales con el objetivo de analizar su patrón altitudinal y determinar qué factores locales y climáticos están definiendo este proceso. Se estudiaron cinco de las especies dominantes de los bosques de la Península Ibérica, tres con una distribución boreal con poblaciones en el límite sur de su distribución (Pinus sylvestris, Pinus uncinata y Fagus sylvatica), y otras dos de distribución típicamente mediterránea (Quercus ilex y Pinus nigra). Para ello tomamos datos de densidad y crecimiento primario anual de juveniles y de diversas variables bióticas y abióticas en 306 parcelas agrupadas en 9 localidades. Los crecimientos de los juveniles más jóvenes (< 5 años) presentaron una tendencia común a disminuir al aumentar la altitud, patrón que desapareció con los juveniles de mayor edad. Además se detectó un patrón asimétrico en las tres especies de pino, apareciendo mayores abundancias de juveniles en la mitad superior de su rango altitudinal. En cuanto a los factores que determinan la presencia y abundancia de regeneración hubo gran disparidad entre las especies. Sin embargo, de manera generalizada, se observó un claro efecto directo del clima sobre la demografía y estado de los juveniles de las cinco especies, e importantes interacciones entre éstos y la vegetación herbácea y arbustiva (competencia/facilitación), interacciones a su vez moduladas por el climaPeer Reviewe
