Effect of soil and canopy factors on vegetation of Quercus robur woodland in the boreo-nemoral zone: A plant-trait based approach
2013
Abstract The aim of the study was to determine the effect of soil and canopy on the understory vegetation of Quercus robur stands in Latvia, located in the boreo-nemoral zone. To determine the main processes regulating formation of the plant communities, the understory vegetation of Q. robur stands was described using plant traits. Vegetation and soils were described in 24 plots representing contrasting soil types and tree species composition. Redundancy analysis was used to determine the relation between vegetation, described using plant traits (proportion of species with each trait), and soil and canopy factors. About 50% of the variation in vegetation described by plant traits was explai…
Link between microbial diversity, stability of microbial communities and soil organic matter turnover
2014
Soil microbial communities act as important agents of the biological soil functioning, particularly through their involvements in the transformations of biogeochemical cycles (C, N, P…). In agro-ecosystems, the diversity of these communities is affected by perturbations associated to agricultural practices, and the significance of these modifications in terms of preservation of biological functioning and sustainability of agricultural systems has emerged as a central issue in the environmental sciences. Whereas the role of biodiversity has been well studied for macroorganisms, in particular for plants; the biodiversity/activity relationship is still largely unknown for soil microorganisms. …
Metabolic responses of microbial community in soil amended with fresh leaves and leaf extracts from eucalyptus spp.
Field observations reveal that often large areas of soil surface beneath Eucalyptus occidentalis Endl. are completely bare or with scant vegetation. Moreover, previous studies have showed that other species of Eucalyptus, such as Eucalyptus camaldulensis Dehn, may be effective in suppressing seed germination and weed growth. Such effects have been ascribed to the large number of secondary metabolites within Eucalyptus leaves. Due to their inhibition activity against weeds, leaf extracts might be used for an integrated weed management context, in accordance with the Directive 2009/128/EC. Several studies exist about the effects of Eucalyptus leaf extracts on weeds, whereas they are lacking o…

I libri, la biblioteca, la città
2021
Molti e suggestivi sono i modi per declinare il tema dei libri e della città. Il primo è quello che legge e interpreta le corrispondenze tra alcuni libri e specifiche città, con un approccio solo apparentemente letterario poiché potrebbe orientare a considerazioni di carattere spaziale oltre che storico e sociale. Un secondo aspetto guarda ai libri e agli spazi intesi come elementi di mediazione (o di interazione) con la città: sono le biblioteche che danno presenza ai libri e che si offrono come luoghi della cultura: Rappresentano lo spazio dei libri nella città e della città. La prima questione, riguardante le simmetrie libri-città, è troppo affascinante per non essere accennata con qualc…
Necesidades de formación en pedagogía hospitalaria. Valoración de expertos en materia de competencias docentes específicas.
2020
Este artículo se encuentra disponible en la siguiente URL: https://revistaseug.ugr.es/index.php/profesorado/article/view/8130/pdf Este artículo pertenece al número que lleva por título "Los objetivos de desarrollo sostenible: aportes desde la investigación educativa comprometida". La formación específica en Pedagogía Hospitalaria es, en la actualidad, una asignatura pendiente en la formación universitaria de los futuros maestros. Desde la óptica de que cualquier maestro, a lo largo de su carrera profesional, puede encontrarse con un alumno/a que enferme, la formación en Pedagogía Hospitalaria no debe estar dirigida exclusivamente a los docentes que desarrollan su carrera profesional dentro …
Varied response of underground and aboveground plant matter: functional diversity of three different vegetational types after translocation to reclai…
2019
The indicators of functional diversity are increasingly used to assess the conservation effectiveness of the most valuable habitats. However, little is known about the response of functional traits, their diversity, and divergence in plant communities after translocation. To assess how functional diversity changes on dry heath, meadow, and fen after translocation of entire turfs of vegetation from an airport area to the Botanical Garden in Radzionkow, we used leaf–height–seed (LHS) traits (specific leaf area, height, and seed mass) and vegetative traits (bud bank size, bud bank depth, and lateral spread). We also measured community weighted means and multifunctional diversity metrics (funct…
Structure and evolution of a European Parliament via a network and correlation analysis
2016
We present a study of the network of relationships among elected members of the Finnish parliament, based on a quantitative analysis of initiative co-signatures, and its evolution over 16 years. To understand the structure of the parliament, we constructed a statistically validated network of members, based on the similarity between the patterns of initiatives they signed. We looked for communities within the network and characterized them in terms of members' attributes, such as electoral district and party. To gain insight on the nested structure of communities, we constructed a hierarchical tree of members from the correlation matrix. Afterwards, we studied parliament dynamics yearly, wi…
Special Civil Law as a Sign of Political Identity: A Constitutional Approach to the Case of the Valencian Community
2013
We seek to clarify the political terminology and meaning of what is contained in the Valencian Statute in the light of the (far more developed and diverse) doctrinal and jurisprudential contributions to arise from the demands of other autonomous communities. This is necessary after the 2006 reform of the Valencian Statute, due to the tendency towards historical law evident therein, and is also essential if progress is to be made towards the constitutional reform that will bring to a close the evolution of the Autonomous State into an ordered Federal State.
Come le tazze del vasaio. Narrazioni, verità e controcondotte
2021
Il saggio affronta il tema di una memoria storica che non ricada nello storicismo e può essere solo l’esito di una narrazione pubblica e collettiva che non confluisce nella costruzione di un monumento. La condivisione di una memoria storica non va intesa come la costruzione di un prodotto condiviso, esito di un processo che sistematizza in senso teleologico le singole voci, dando vita ad una voce singola, bensì come la pratica delle posizioni eterogenee e antagoniste che rifuggono da qualsivoglia deriva sistematizzante che risponda al meccanismo di reductio ad unum matrice della modernità eurocentrica occidentale che assimila o espelle le posizioni differenti. Una memoria, dunque, che mos…
