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…

How can I signal my quality to emerge from the crowd? A study in the crowdsourcing context

2022

Crowdsourcing contests are characterized by an intensive level of competition because of the extensive number of solvers that voluntarily self-select to participate in such contests. This study aims at understanding how solvers can signal their quality attributes through the community functionalities, i.e. the online profile and the discussion blog of the crowdsourcing platform, to improve their chances of winning crowdsourcing contests. Drawing on signaling theory, we hypothesize that signaling their skills and capabilities by crafting profiles rich in personal and professional information and by participating actively within the discussion blog by posting and commenting, solvers can influ…

Perceptions of justice influencing community acceptance of spent nuclear fuel disposal : A case study in two Finnish nuclear communities

2019

Final disposal of spent nuclear fuel (SNF) from nuclear power plants (NPPs) is an ethical issue with implications within and across generations. We address this issue from the perspective of nuclear communities that host nuclear waste disposal sites. These are primarily the communities that face injustice due to the potential radiological risks. A resident survey (n = 454) was conducted in two Finnish nuclear communities, i.e. Eurajoki and Pyhäjoki, that are being considered as alternative sites for a second repository for SNF. The nuclear waste management (NWM) company Posiva is already building a repository in Eurajoki, the first in Finland. These communities are in different stages of th…

Senescence and longevity : from physiological mechanisms to evolutionary processes : studies in birds and mammals

2012

There is an incredible diversity of lifespan in the animal kingdom ranging from a few days for small gastrotrichs worms to several hundred of years for some bivalves or tortoises. This amazing diversity has long questioned biology researchers. The growing interest in the phenomenon of aging, mainly due to the increase in life expectancy in humans, has questioned researchers on processes that determine patterns of longevity and ageing. On the one hand, biomedical and biogerontological studies helped describe numerous cellular and physiological mechanisms related to aging. Among these mechanisms, oxidative stress has been identified as playing a major role, through life-time accumulation of d…

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…

Halfway up the trophic chain: development of parasite communities in the sparid fish Boops boops

2007

SUMMARYWe examined the patterns of composition and structure of parasite communities in the Mediterranean sparid fish Boops boops along a gradient of fish sizes, using a large sample from a single population. We tested the hypothesis that species forming the core of the bogue parasite fauna (i.e. species which have a wide geographical range and are responsible for recognizable community structure) appear early in the fish ontogeny. The sequential community development observed supported the prediction that core species appear in the fish population earlier than rare and stochastic species. There was also a strong correlation between the order of ‘arrival’ of the species and their overall pr…

Community action and planning. Contexts, drivers and outcomes

2014

With trust in top-down government faltering, community-based groups around the world are displaying an ever-greater appetite to take control of their own lives and neighbourhoods. Government, for its part, is keen to embrace the projects and the planning undertaken at this level, attempting to regularise it and use it as a means of reconnecting to citizens and localising democracy. This unique book analyses the contexts, drivers and outcomes of community action and planning in a selection of case studies in the global north: from emergent neighbourhood planning in England to the community-based housing movement in New York, and from active citizenship in the Dutch new towns to associative a…

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 …

Morphological Similarity and Ecological Overlap in Two Rotifer Species

2013

Co-occurrence of cryptic species raises theoretically relevant questions regarding their coexistence and ecological similarity. Given their great morphological similitude and close phylogenetic relationship (i.e., niche retention), these species will have similar ecological requirements and are expected to have strong competitive interactions. This raises the problem of finding the mechanisms that may explain the coexistence of cryptic species and challenges the conventional view of coexistence based on niche differentiation. The cryptic species complex of the rotifer Brachionus plicatilis is an excellent model to study these questions and to test hypotheses regarding ecological differentia…
