Survey of mammals in the Strict Nature Reserve of Bosco Nordio (Chioggia, province of Venezia, NE Italy)
No full textMammals were surveyed in the Strict Nature Reserve of Bosco Nordio, from March to No-vember 2015. The survey was performed using infrared camera traps and dogs trained to search signs and tracks of wild animals. Overall, during the survey, were detected 12 species: West European hedgehog, Erinaceus europaeus, European mole, Talpa europaea, Udine shrew, Sorex arunchi, European hare, Lepus europaeus, long-tailed field mouse, Apodemus sylvaticus, striped field mouse, Apodemus agrarius, brown rat, Rattus norvegicus, red fox, Vulpes vulpes, beech marten, Martes foina, least weasel, Mustela nivalis, European badger, Meles meles, e fallow deer, Dama dama. The research allowed to update the checklist of the species present in the protected area, and to spot the striped field mouse in a new site of the Venetian Po plane. Moreover, the survey permitted us to achieve a better knowledge of the distribution of badgers, fallow deers and foxes, through the development of specific concentration maps (Kernel Density Estimation). By overlapping the concentration maps and the Habitats map of the SCI/SPA IT3250032 it has been possible to determine the habitats of greater occurrence of badger, fox and fallow deer, and calculate their relative percentage with respect to the total surface occupied in the whole protected area. The information obtained through this study is important for future management planning consistent with the necessities of protection and conservation of the resident species
Application of a methodology foe the exhaustive census of badger, Meles meles, setts, in the strict nature reserve of Bosco Nordio (Chioggia, province of Venice, NE Italy) (Carnivora: Mustelidae)
No full textAim of this work is the elaboration of an efficient procedure for the detection and the census of European badger Meles meles setts in the Strict Nature Reserve of Bosco Nordio. Badger burrows are easily detectable for the stockpile of material and the presence of footprints and latrines, but an exhaustive census can be a difficult task, depending on land and vegetation conditions. Every lack of coverage of land patches can lead to misleading evaluations and wrong conclusions. To cover the whole area of the Reserve and minimizing the possibilities of error, we used a free smartphone application (Endomondo Sport Tracker), developed for sport activity, which allows you to view the itinerary as a line on a satellite image of the territory. The research protocol consisted in searching and spotting digging signs (piled up materials, galleries), signs of presence (latrines, footprints) or signs of passage. Using the application made the research more efficient and quicker, allowing to diverge from the survey path (to follow an animal track) and coming back with confidence, without missing any survey area. Every gallery or other signs of badger presence were marked with GPS coordinates, and the characteristics of the point were registered in a specific data sheet, then a camera trap was set up to control the passages. Nowadays different free GPS tracking applications for smartphones are available. Their use can help to rapidly and efficiently carry out total counts, without more expensive and technologically advanced equipment
Dal pennello alla parola, dalla spada all’azioneIl soldato Massimo d’Azeglio
No full textElles ne sont ni rares ni secondaires les batailles qu’a livrées le “soldat” Massimo d’Azeglio au cours de son existence aventureuse et riche de multiples expériences. De la peinture à l’écriture et de la politique à la guerre, cet aristocrate piémontais s’est imposé comme une personnalité essentielle de la pensée et de l’action propres au Risorgimento. Il a acquis sa stature intellectuelle et historique en empoignant tour à tour ou simultanément son pinceau, sa plume et son épée, ses trois armes préférées. Poussé, dans sa jeunesse, par la volonté de lutter pour s’affranchir d’une éducation rigide, d’un milieu social et familial étouffant, il a ensuite été amené, par la maturité et de profondes motivations patriotiques, à peindre, écrire et combattre pour l’indépendance de l’Italie et pour l’unité des Italiens.Non sono poche né trascurabili le battaglie combattute dal “soldato” Massimo d’Azeglio nel corso della sua vita avventurosa e ricca di tante esperienze. Dalla pittura alla scrittura e dalla politica alla guerra, l’aristocratico piemontese si è affermato come una personalità essenziale del pensiero e dell’azione risorgimentali. Ha conquistato la sua dimensione intellettuale e storica impugnando successivamente o contemporaneamente il pennello, la penna e la spada, le sue tre armi predilette. Spinto in gioventù dalla volontà di lottare per la propria emancipazione da un’educazione rigida e da un’atmosfera socio-famigliare soffocante, la maturità e profonde motivazioni patriottiche lo hanno poi indotto a dipingere, a scrivere e a combattere insieme per l’indipendenza dell’Italia e per l’unità degli italiani

No full textSPADA: A Sparse Approximate Data Structure Representation for Data Plane Per-flow Monitoring
No full textAccurate per-flow monitoring is critical for precise network diagnosis, performance analysis, and network operation and management in general. However, the limited amount of memory available on modern programmable devices and the large number of active flows force practitioners to monitor only the most relevant flows with approximate data structures, limiting their view of network traffic. We argue that, due to the skewed nature of network traffic, such data structures are, in practice, heavily underutilized, i.e. sparse, thus wasting a significant amount of memory.
This paper proposes a Sparse Approximate Data Structure (SPADA) representation that leverages sparsity to reduce the memory footprint of per-flow monitoring systems in the data plane while preserving their original accuracy. SPADA representation can be integrated into a generic per-flow monitoring system and is suitable for several measurement use cases. We prototype SPADA in P4 for a commercial FPGA target and test our approach with a custom simulator that we make publicly available, on four real network traces over three different monitoring tasks. Our results show that SPADA achieves 2× to 11× memory footprint reduction with respect to the state-of-the-art while maintaining the same accuracy, or even improving it
