Luminescence Dating of Fluvial Deposits in the Rock Shelter of Cueva Antón, Spain
2015
Abstract The fluvial sediments at Cueva Antón, a Middle Palaeolithic rock shelter located in the valley of the River Mula (Southeast Spain), produced abundant lithic assemblages of Mousterian affinities. Radiocarbon dates are available for the upper part of the archaeological succession, while for the middle to lower parts chronometric data have been missing. Here we present luminescence dating results for these parts of the succession. Quartz OSL on small aliquots and single grain measurements yield ages ranging from 69 ± 7 ka to 82 ± 8 ka with a weighted mean of 72 ± 4 ka for sub-complexes AS2 to AS5. Equivalent dose estimates from large aliquots were highest and inconsistent with those f…
Unveiling distribution patterns of freshwater phytoplankton by a next generation sequencing based approach.
2012
The recognition and discrimination of phytoplankton species is one of the foundations of freshwater biodiversity research and environmental monitoring. This step is frequently a bottleneck in the analytical chain from sampling to data analysis and subsequent environmental status evaluation. Here we present phytoplankton diversity data from 49 lakes including three seasonal surveys assessed by next generation sequencing (NGS) of 16S ribosomal RNA chloroplast and cyanobacterial gene amplicons and also compare part of these datasets with identification based on morphology. Direct comparison of NGS to microscopic data from three time-series showed that NGS was able to capture the seasonality in…
Follow-up trends of parasite community alteration in a marine fish after the Prestige oil-spill: shifting baselines?
2008
This study evaluates the follow-up trends in the composition and structure of the parasite communities in the marine sparid Boops boops after the Prestige oil-spill. A total of 400 fish comprising 11 seasonal samples was analyzed from three impacted localities on the Atlantic coast of Spain. A large number of parasite species was recovered only after the spill thus suggesting a substantial alteration of the marine food webs. Post-spill communities exhibited higher richness and abundance due to the significant changes in the abundance of the common species, the latter indicating accelerated parasite transmission rates. Multivariate analyses at two nested scales detected a directional trend i…
Functional implications of the staminal lever mechanism in Salvia cyclostegia (Lamiaceae)
2011
Flower morphology and inflorescence architecture affect pollinator foraging behaviour and thereby influence the process of pollination and the reproductive success of plants. This study explored possible ecological functions of the lever-like stamens and the floral design in Salvia cyclostegia.Flower construction was experimentally manipulated by removing either the lower lever arms or the upper fertile thecae of the two stamens from a flower. The two types of manipulated individuals were intermixed with the control ones and randomly distributed in the population.Removing the sterile lower lever arms significantly reduced handling time per flower of the main pollinator, Bombus personatus. I…
Carbon stock increases up to old growth forest along a secondary succession in Mediterranean island ecosystems.
2019
The occurrence of old-growth forests is quite limited in Mediterranean islands, which have been subject to particularly pronounced human impacts. Little is known about the carbon stocks of such peculiar ecosystems compared with different stages of secondary succession. We investigated the carbon variation in aboveground woody biomass, in litter and soil, and the nitrogen variation in litter and soil, in a 100 years long secondary succession in Mediterranean ecosystems. A vineyard, three stages of plant succession (high maquis, maquis-forest, and forest-maquis), and an old growth forest were compared. Soil samples at two soil depths (0-15 and 15-30 cm), and two litter types, relatively undec…
Impact of woody encroachment on soil organic carbon and nitrogen in abandoned agricultural lands along a rainfall gradient in Italy
2011
Land use changes represent one of the most important components of global environmental change andhave a strong influence on carbon cycling. As a consequence of changes in economy during the last century, areas of marginal agriculture have been abandoned leading to secondary successions. The encroachment of woody plants into grasslands, pastures and croplands is generally thought to increase the carbon stored in these ecosystems even though there are evidences for a decrease in soil carbon stocks after land use change. In this paper, we investigate the effects of woody plant invasion on soil carbon and nitrogen stocks along a precipitation gradient (200–2,500 mm) using original data from pa…
Reati fiscali e successione nel tempo di leggi tributarie
2013
La modifica della norma tributaria, anche di derivazione comunitaria o internazionale, che incida sugli elementi essenziali della fattispecie incriminatrice, comporta l'applicazione della disposizione più favorevole tra quella in vigore al momento della consumazione del delitto e quella successiva all'entrata in vigore.
The Relevance of Knowledge Types and Learning Pathways in Wine Family Business Succession
2013
Abstract Aspects of family business succession process are many times neglected during the life of the founder or the generation that must be getting ready for the hand-off. The paper is allowing even to a rude observer to understand the importance, the concepts, the typology and the implications of following a specific learning pathway and choosing a particular category of successor (insider or outsider), starting from situations where inside-family succession is preferable. The objective is twofold: (1) to highlight knowledge types that are easier to be transferred to internal successors, and (2) to identify context factors that facilitate family internal succession. We will demonstrate t…
Success Factors in Funding Acquisition for Research Projects through Competitive Calls: A study of R&D Public Centres
2017
Durante los últimos años, la capacidad de generación de recursos financieros derivados de la obtención de fondos competitivos ha sido una preocupación creciente para las organizaciones públicas de investigación y desarrollo (I+D), al garantizar su supervivencia y el futuro de los actuales sistemas de bienestar público implementados en la mayoría de los países europeos (Bazeley, 1998; Lee y Om, 1996; Muñoz, 2007; Santamaría, Brage-Gil, y Modrego, 2010). La literatura actual describe ampliamente las características y el impacto de los principales programas de financiación competitiva internacional (Galsworthy y McKee, 2013; Grimpe, 2012; Laudel, 2005, 2006), la magnitud de la eficacia de los …
El testament del marqués de Villatorcas i la disputa del compte de Cervelló per l'herència paterna : una altra conseqüència de l'exili austracista.
2007
Felipo Orts, Amparo - Amparo.Felipo@uv.es En el context de les conseqüències de l'exili austriacista vinculat a la Guerra de Successió, aquest article estudia els desencontres familiars que va haver de salvar don Juan Basilio de Castellví, exiliat a Viena, per a veure reconeguts els seus drets a la part de l'herència familiar que assegurava correspondreli, derivats, al seu torn, del conflicte personal que per a son pare, el marqués de Villatorcas, va haver de suposar la necessitat de disposar les seues últimes voluntats -en forma de poder públic- abans de la firma de la Pau de Viena de 1725.
