Introduzione a Anniversary Forum Cirese 101. Rileggere le "Osservazioni sul folclore" di Antonio Gramsci, Anuac, 11, 1, 2022.

Book forum su Ernesto De Martino, La fine del mondo. Contributo all'analisi delle apocalissi culturali, nuova edizione a cura di Giordana Charuty, Daniel Fabre e Marcello Massenzio, 2019 [ed. fr. La fin du monde. Essai sur les apocalypses culturelles, Éditions EHESS, 2016].

This Anniversary Forum commemorates the figure and work of Alberto Mario Cirese (1921-2011), a prominent Italian anthropologist, on the 101st anniversary of his birth. Cirese's reading of Gramsci has been highly influential. For this reason, the forum is built around the re-edition of the English translation of Cirese's essay Gramsci's Observations on folklore: Conceptions of the world, spontaneous philosophy and class instinct. The essay is followed by short critical interventions of attentive readers of Gramsci's anthropology: Kate Crehan, Riccardo Ciavolella, Giovanni Pizza. The forum ends with a contribution by Jorge A. González, who recalls his encounter and relation with Cirese, while offering new historical insights on Cirese's teaching, study and research activities in Mexico.

The aim of this paper is to highlight current opportunities and expected benefits of establishing a transboundary large marine protected area (LMPA)-specifically a no-trawl area - in one of the most exploited sectors of the Mediterranean, the Adriatic Sea. A no-trawl area is examined as a strategy to foster recovery of the local marine ecosystems and economies, and to meet international conservation targets and EU legal mandates. Based on a review of published studies documenting the positive outcomes of previous trawling bans in other regions, and of current initiatives and opportunities within the Mediterranean region, it is concluded that large-scale protection of the Adriatic with a no-trawl zone is a promising and feasible approach for reversing ecological and socioeconomic losses in this basin. In particular, ecosystem protection can be established in the Mediterranean through a proposal for a Fisheries Restricted Area (FRA) to the general Fisheries Commission for the Mediterranean (GFCM). The successful establishment and function of a FRA or LMPA will depend on its support by the governments of the surrounding countries, as well as involvement and participation of key user groups

River ecosystems are characterised by a naturally high level of hydrodynamic perturbations which create aquatic-terrestrial habitats indispensable for many species, as well as for the human beings' welfare. Environmental degradation and habitat loss caused by increasing anthropogenic pressures and global change affect freshwater aquatic ecosystems worldwide and have caused changes in water flow regimes and channels morphologies. These, in turn, decreased the natural flow capacity and reduced habitat availability, thus causing severe degradation of rivers' ecological integrity. The ecological flow (e-flow) is commonly intended as the quantity, timing, duration, frequency and quality of water flows required to sustain freshwater, estuarine and near shore ecosystems and the human livelihoods and well being. Maintaining the e-flow represents a potential tool for restoring and managing river ecosystems, to preserve the autochthonous living communities, along with environmental services and cultural/societal values. In the last decade, methods for the determination of the e-flow in European rivers moved from a simply hydrological approach towards establishing a linkage between the hydrological regime and the good ecological status (GES) of the water bodies, as identified by the European Water Framework Directive (WFD; 2000/60/EC). Each Member State is required to implement and integrate into the River Basin Management Plans (RBMP) a methodology for the determination of the e-flow, ensuring that rivers can achieve and maintain the GES. The competent river basin authorities have thus to ascertain whether national methodologies can be applied to different river typologies and basin environment characteristics. In this context, we narratively review the e-flow assessments in the heterogeneous Italian territory, in particular on a water scant region such as Sardinia, by analysing laws, guidelines and focusing on study cases conducted with micro and meso-scale hydraulic-habitat approaches. In the sight of a more ecological-based application of national e-flow policy, we suggest that meso-habitat methods provide a valuable tool to overcome several limitations of current e-flow implementation in the Italian territory. However, to face future challenges, such as climate change adaptation, we stress the need for further experimental studies to update water management plans with greater attention for nature conservation.

The carbon cycle of the Arctic Ocean is tightly regulated by land-atmosphere-cryosphere-ocean interactions. Characterizing these environmental exchanges and feedbacks is critical to facilitate projections of the carbon cycle under changing climate conditions. The environmental drivers of sinking particles including organic carbon (OC) to the deep-sea floor are investigated with four moorings including sediment traps and currentmeters at the Arctic gateway in the eastern Fram Strait, which is the area where warm anomalies are transported northwards to the Arctic. Particles fluxes were collected over one year (July 2010-July 2011) and have been analysed to obtain the content of the lithogenic fraction, calcium carbonate, OC and its stable isotopes, opal, and the grain size. Records of near bottom current speed and temperature along with satellite observations of sea ice extent and chlorophyll-a concentration have been used for evaluation of the environmental conditions.We found increased lithogenic fluxes (up to 9872mgm-2d-1) and coarsening grain size of settling particles in late winter-early spring. At the same time, intensifications of the northward flowing west Spitsbergen current (WSC) were recorded. The WSC was able to resuspend and transport northwards sediments that were deposited at the outlet of Storfjordrenna and on the upper slope west of Spitsbergen. The signal of recurrent winnowing of fine particles was also detected in the top layer of surface sediments. In addition, an increased arrival of sea ice transported ice rafted detritus (>414 detrital carbonate mineral grains larger than 1mm per m2) from the southern Spitsbergen coast along with terrestrial organic matter was observed beyond 1000m of water depth during winter months. Finally, the downward particle fluxes showed typical temporal variability of high latitudes, with high percentages of the biogenic compounds (opal, organic carbon and calcium carbonate) linked to the phytoplankton bloom in spring-summer. However, on an annual basis local planktonic production was a secondary source for the downward OC, since most of the OC was advected laterally by the WSC. Overall, these observations demonstrated the sensitivity of the downward flux of particles to environmental conditions such as hydrodynamics, sea ice rafting, and pelagic primary production. Future alteration of the patterns of natural drivers due to climate change is thus expected to cause major shifts in the downward flux of particles, including carbon, to the deep sea ecosystems. © 2015 Elsevier Ltd. ; This research has been supported by the projects HERMIONE (FP7-ENV-2008-1-226354) and GRACCIE-CONSOLIDER (CSD2007-00067), and a Catalan Government Grups de Recerca Consolidats grant (2009 SGR 1305).

14 pages, 6 figures, 1 table, supplementary material https://www.frontiersin.org/articles/10.3389/fmars.2021.626843/full#supplementary-material ; Restoration is considered an effective strategy to accelerate the recovery of biological communities at local scale. However, the effects of restoration actions in the marine ecosystems are still unpredictable. We performed a global analysis of published literature to identify the factors increasing the probability of restoration success in coastal and marine systems. Our results confirm that the majority of active restoration initiatives are still concentrated in the northern hemisphere and that most of information gathered from restoration efforts derives from a relatively small subset of species. The analysis also indicates that many studies are still experimental in nature, covering small spatial and temporal scales. Despite the limits of assessing restoration effectiveness in absence of a standardized definition of success, the context (degree of human impact, ecosystem type, habitat) of where the restoration activity is undertaken is of greater relevance to a successful outcome than how (method) the restoration is carried out. Contrary to expectations, we found that restoration is not necessarily more successful closer to protected areas (PA) and in areas of moderate human impact. This result can be motivated by the limits in assessing the success of interventions and by the tendency of selecting areas in more obvious need of restoration, where the potential of actively restoring a degraded site is more evident. Restoration sites prioritization considering human uses and conservation status present in the region is of vital importance to obtain the intended outcomes and galvanize further actions. ; Research funded by the EU project MERCES of the European Union's Horizon 2020 research (Grant agreement No. 689518, http://www.merces-project.eu). ; Research funded by the EU project MERCES of the European Union's Horizon 2020 research (Grant agreement No. 689518, http://www.merces-project.eu) ; Peer reviewed
