Evidence de l'adaptation des communautés microbiennes sédimentaires de rivière à la minéralisation du diuron: influence du ruissellement et de l'éros…
2010
International audience; Purpose Surface runoff and erosion are major drivers of pesticide transport from soils to rivers draining vineyard watersheds. A recent study showed that applications of diuron on vineyards and diuron dispersal could lead to microbial adaptation to diuron biodegradation from treated soils to the receiving hydrosystem. Given the limited knowledge on microbial adaptation to pesticide degradation in aquatic environments, we conducted a microcosm study designed to assess the impact of runoff and erosion processes on the adaptation of riverine-sediment microbial communities to diuron mineralization. Materials and methods The experimental laboratory set-up consisted in aqu…

Effects of the introduction of a biocontrol strain of Trichoderma atroviride on non target soil micro-organisms
2009
International audience; The main objective of this study was to assess the impact of the application of an antagonistic strain of Trichoderma atroviride on the native microbial soil communities. The structures of the fungal and bacterial communities were assessed by T-RFLP (terminal restriction fragment length polymorphism) method, based on T-RFLP analysis of 18S and 16S rRNA genes, respectively. Results showed that the introduction of the strain I-1237 into two soils slightly modified the microbial diversity, only for a short period of time. Nine months post-inoculation resilience took place, resulting in similar structures of the fungal and bacterial communities in the inoculated and cont…
Info-communicationnal approach of medical cannabis self-medication : analysis of figures mobilized in knowledge legitimation within a community dedic…
2022
This thesis proposes an infocommunicational approach to self-medication with medical cannabis. We question the logic of knowledge legitimization in a context where the coercive power of the French state is exercised. We seek to understand how the use of cannabis is determined in a radically constrained legislative framework, for users in a recreational or self-medication approach, but also for doctors and patients in a medical approach. To do this, we analyze the processes of knowledge legitimization that allow the development of practical know-how allowing individuals to consume cannabis in a self-medication approach within clandestine health communities of practice, supported by participa…
Energy self-consumers and renewable energy communities in Italy: New actors of the electric power systems
2021
Abstract The new European Directive RED-II on the promotion of the use of renewable energy sources has introduced the concept of the Renewable Energy Community. This new entity has the potential to change the relations among end-users and the latter and the other actors of the energy sector. In particular, the electrical sector appears the most influenced by the implementation of this paradigm. Indeed, the need for self-consumption and for exploiting the full potential of renewable energy in a Renewable Energy Community influences how the end-users exchange energy with the power grid, the rules for their connection to the grid, the implementation of Demand Response and other energy manageme…
Ethnobotanical knowledge in some rural communities of northern Sicily (Palermo, Italy)
2018
An ethnobotanical study was carried out to document the uses of wild plants among some local communities of Sicily (southern Italy). We recorded 48 taxa belonging to 45 genera included in 32 families. 30 taxa are used as medicinal plants, 22 taxa as food and 9 for handicraft use. In comparison with other ethnobotanical studies carried out in Sicily and other Italian territories, some uses of the plants reported by the local population in the study area are peculiarities. The analysis of data shows that the level of traditional knowledge on use of plants in province of Palermo is poor, highlighting a considerably advanced state of cultural erosion. The results of our investigation confirm th…
Hydrophytic vegetation aspects in the Nebrodi Mountains (Sicily).
2011
A study of the hydrophyte communities of some small ponds in the beech-wood belt of the higher Nebrodi Mts is presented. A new association of shallow stagnant water bodies, the Utriculario-Potametum natantis, is described. Its biological structure, biogeographical characteristics, syntaxonomic position, phytosociological relationships and dynamic links are discussed.
Effects of Ocean Acidification on physiology, behaviour and ecology of fish
CO2 concentration in the atmosphere is increasing at unprecedented rate since the last 800,000 years due to rising fossil fuel combustion, industrial processes and land use by humans. By absorbing part of this gas from the atmosphere, Oceans contribute to the mitigation of climatic changes, but at the cost of greater modifications of their physical and chemical characteristics. CO2 dissolved in the seawater leads to increased bicarbonate (HCO3 -) and hydrogen ions (H+) concentrations with a consequent pH drop, a phenomenon known as Ocean Acidification (OA). If global policy will not put in force mitigation measures to reduce CO2 emissions, it is projected that partial pressure of dissolved …
Building community spaces: Processes and actions In the City of Mercato Ballarò in Palermo
2022
The rediscovery of the cultural value of a project, the creation of new imagery in marginal places and the new aesthetics of temporality are some of the emerging issues in the city of crisis which are measured through processes of active involvement in community relations. There are many cities that have recognised urban markets as an integral part of local economies, with great benefits also at cultural and social levels. The hypothesis of triggering regenerative processes in the urban and social fabric in the unstable urban market context is the foundation of this research-action contribution developed through active relationships with public entities, associations and citizens. The syste…
