During the Spring of 2011, we studied the bird community in an area of Val Borbera, in the province of Alessandria (NW Italy). In the study area, situated at an altitude between 655 and 1700 m a.s.l., we conducted 110 points count ten minutes each in four microhabitats (agricultural areas, shrubs, forests, and prairies). In total, we surveyed 72 species, of which 51 were passerine and 21 non passerine. The most abundant species were Sylvia atricapilla, Phylloscopus collybita, Apus apus, and Turdus merula. In the agricultural areas, we detected a total of 50 species (Sylvia atricapilla, Parus major, Turdus merula were the most abundant). In the shrubs, we detected 30 species (Sylvia atricapilla, Parus major, Fringilla coelebs, Phylloscopus collybita, Turdus merula, Erithacus rubecula were the most abundant). In the forest areas, we found 45 species (Sylvia atricapilla, Parus major, Fringilla coelebs, Phylloscopus collybita, Turdus merula, Erithacus rubecula were the most abundant), and in the prairies, we detected 48 species (Alauda arvensis, Anthus campestris, Sylvia atricapilla, Turdus merula, Anthus trivialis, Sylvia communis were the most abundant). Compared to the other macro habitats, the agricultural areas have a significantly high abundance and richness in species, which highlights the importance of the agricultural mosaics in the Piedmont and mountain areas. The data which has been collected so far confirms the important role of this area, given the presence of some species which are rare at a regional scale. [ABSTRACT FROM AUTHOR]

- Abstract
In Italy, the launch of the online portal www.ornitho.it in 2009 has played a key role in advancing our knowledge about the abundance, geographical distribution and phenology of birds, and has greatly improved everyday ornithological issues. Indeed, the extensive participation by many observers has provided an opportunity to obtain new insight into the phenology of many species of migratory birds, such as Tringa sp. In this paper, I have analysed the data gathered between 2010 and 2014 on the genus Tringa in Lombardy, amounting to a total of 5,590 validated records for spring and autumn migrations. The analysis revealed that the rice-farming area of S-W Lombardy - which covers more than 90,000 hectares located mainly in the province of Pavia - represents an invaluable habitat during the spring migration by supporting the bulk of migrating waders. Other man-made habitats, such as restored sand and gravel pits and water-collection tanks, are of similar importance for the diversity of the wader community, but, together with the few natural wetlands, support much lower numbers of individuals. The wood sandpiper is the most abundant species, with groups reaching 600 individuals, followed by the spotted redshank and the greenshank. The green sandpiper is the most common and widespread species, with a low number of individuals reaching the highest altitudes (above 2,600 m a.s.l. in the province of Sondrio) during the autumn migration. The common redshank is relatively rare, generally distributed around 200 m a.s.l. in the provinces of Pavia and Milan, while the marsh sandpiper is definitely rare, with only 68 records in the five-year period analysed.

5. Market structures.
- Abstract
In recent years, the debate on the nature and outcome of the late medieval ‘crisis’ has taken a new lease on life. According to the more recent interpretation, the demographic and political ‘crises’ acted as a catalyst for structural changes that pushed the late medieval economy onto a higher path of growth, rather than ushering in a long phase of contraction, as has long been argued by historians of a ‘neo-Malthusian’ persuasion. This revisionist case rests on two propositions. In the first place, the consequences of the demographic slump following the Black Death are seen in a more optimistic light. On the supply side, the demographic crisis reduced population pressure on basic agricultural resources and made it possible to make more efficient use of land and labour; on the demand side, the sharp tightening of labour markets caused a redistribution of income from landlords and employers to the peasantry and urban wage earners, who spent much of their increased disposable income on cheap manufactures and on foodstuffs with higher added value. This claim has a long intellectual pedigree and has gained a broad acceptance among scholars. The second proposition is that the rise in the late middle ages of more centralised states, and the consolidation of parcellised sovereignty that it entailed, reduced the institutional costs of trade in commodities and information both by lowering feudal and urban tariffs, and by aiding the development of more efficient and integrated trading networks.

6. Fiscality, politics and dominion in Florentine Tuscany at the end of the middle ages.
- Abstract
Between the later middle ages and the early modern period Florentine citizens managed money, pen and ink for princes and sovereigns in all of Europe. But this clear fame in finance has not stopped modern historians from passing severe judgment on these same men when it came to the fiscal administration of their own state. The most recent historiography has emphasised the inability of the Florentines to separate reasons of state from personal, family and factional interests. Its hypotheses are rooted in an alleged Florentine abandonment during the fifteenth century of the mainstream of simplification and rationalisation of the fiscal system. After the return of Cosimo il Vecchio to Florence in 1434, it is asserted, major fiscal confusion and less rigour in the administration of state finances were consonant with the rising political fortunes of the Medici family. This recent understanding was arrived at in the study of Florentine domestic politics, through reconstructing the vital ties between the public debt, short-term credit, and the political connections of the governing families of Florence. The interpretation has also been extended ‘outward’, as it were, to involve the history of the Tuscan regional state. Medicean hegemony, it is said, interrupted relevant processes that had started during the decisive period of territorial expansion, namely the administrative integration of the Florentine dominion, the erosion of the power of the local intermediaries between the central fisc and its taxpayers, and the reinforcement of direct taxes on subjects.

Around a yearly cycle (August 2011 - July 2012), we studied the assemblages of waders (Aves Charadriiformes) occurring in a Mediterranean remnant wetland, obtaining a set of diversity metrics. Mean total abundance shows a complementary pattern when compared to species richness and diversity: the highest values of mean total abundance were observed in December-January, due to high dominance of only one very abundant and gregarious species (the lapwing Vanellus vanellus). On the contrary, in this period, species richness and diversity showed the lowest values. These last metrics were highest in values during the April-September period when a large number of species of conservation concern utilize muddy areas as trophic and stop-over sites, due to the seasonal water stress. The highest values in species turnover index were observed between December-January and February-March when passage migrants (high richness, low abundance) substitute the wintering species (low richness, high abundance). Our data highlight that, in Mediterranean remnant wetlands, strategies should be addressed to increase the muddy suitable areas in the April-September period in order to maximize species richness and diversity. In fact, in these months these habitats host pre- and post-breeding migrant waders of conservation concern. [ABSTRACT FROM AUTHOR]

Around the 2007 yearly cycle, we carried out a transect in a Mediterranean sandy beach (central Italy), a structurally oversimplified ecosystem, elaborating the data in six bimonthly periods and in three longitudinal habitat types. We observed 25 bird species. Assemblages appear heterogeneous at taxonomic-, phenological- and ecological- level. Also normalizing (Margalef index), in winter the beach hosted the richest assemblage, in summer-autumn the lowest. The inner dunal area appears the richest habitat type. Here, the presence of vegetation presumably permits the occurrence of a large availability of different trophic resources for different species. Beaches represent patchy ecosystems with a different availability of resources in space and time that host heterogeneous bird assemblages, different in their ecology and phenology around a yearly cycle.

Presentazione del prototipo del Repository FABB costruito all'interno del progetto Fame e abbondanza nella narrazione popolare in Piemonte (FABB) realizzato fra il 2014-2016. Si tratta di un repository open access, nasce dall'idea di dare visibilità alla rappresentazione che un territorio (il Piemonte) dà di se stesso attraverso il racconto della sua relazione con il cibo. In Piemonte è forte la visione che lega produzione agricola sostenibile, cibi di qualità e saper vivere, ed è anche una regione dove sono stati registrati fenomeni persuasivi come il movimento di Slow Food e operazioni commerciali di successo che hanno ulteriormente connotato l'immagine del Piemonte.

The predominant influence of physico-chemical conditions on community structure in terms of abundance, species richness and diversity of macroinvertebrate assemblages in headwater streams is well documented in literature, but its implications on body size distribution has been not yet considered. Organism size is one of the key determinants of community structure, and how biomass is partitioned among the biota may determine the efficiency of relevant ecological processes. Understanding how the distribution of biomass is linked to abiotic conditions we could predict the effects of environmental changes on aquatic ecosystem processes, particularly in the case of a community with a relative poor composition and with simplified food web structure, like it is present in alpine freshwater systems. For these reasons, we compared the taxonomic structure and individual size distribution of macroinvertebrate assemblages of three Alpine streams presented similar geomorphology, water chemistry, and food chain structure, but different water thermal regimes, mainly influenced by different types of water source. Therefore, temperature was the only significant independent factor that influenced each scenario, and the relation of this variable to biological responses could be measured directly. Our results show that hydromorfological parameters, physico-chemical characteristics and biotic factors explain much of the variability of macroinvertebrate taxonomical structural attributes, but they do not influence body size where the low temperatures have been detected as the main limiting factor. Temperature acts as a key-driver controlling taxonomical structure and invertebrate body size distribution. In agreement with previous findings, higher values of abundance and species richness correspond to warmer temperatures, as well as shifts of biomass distribution towards smaller size classes. Observed patterns underline the relevance of possible implications of global warming on the robustness and functioning (e.g. increase of productivity, functional shift in the food-webs) of high-altitude and high-latitude sensitive ecosystems, such as Alpine headwater streams.

- Abstract
Affluent countries experience serious signs of poverty which in Europe affects more than 78 million persons. The paradox of scarcity in abundance assumes a specific meaning in the case of food insecurity and of food component of poverty, which, based on OCSE and Eurostat data are significantly widespread in every European country. An innovative solution to this paradox becomes from the food banks started 30 years ago in US and then diffused in all European countries. A specific focus is paid to the italian system of food banks coordinated by Food Bank Foundation.

Anziché godere, nella condivisione, delle opere sue, l’uomo s’è andato abituando a godere dei prodotti e poi dai prodotti ha spostato l’attenzione sul guadagno e ha preteso di accumulare sempre di più sino al punto da far prevalere le cose sulle sulla persone e così il godimento è diventato dapprima piacere edonistico e poi sofferenza del limite ed angoscia della perdita. Si dà tanto valore alle cose che contrappuntano i giorni e le ore da smarrire il senso di una provenienza e la speranza di un incontro, e, fatalmente, il troppo amore per le cose fa perdere senso e valore alla vita. L’ideale del possesso e dell’accumulazione, l’idea regolativa della accelerazione, l’incidenza dell’efficientismo tecnologico e dello scientismo, i contributi della filosofia vitalistica, nelle sue diverse espressioni concorrono tutti ad accreditare “un senso generale del diritto alla felicità terrena” , come già nel 1935 ebbe ad osservare J. Huizinga.“Gli uomini avanzano pretese sulla vita” e così, però, diventano sempre meno capaci di accettare la caducità di ogni momento di benessere terreno e diventano persino incapaci di mantenere vivo il senso del valore della vita. In questo contesto valoriale si fa problematico anche l’intervento educativo il quale, per esprimersi in efficacia, richiederebbe una condizione condivisa di significati e di rinvii valoriali, e invece i valori che la cultura partecipa sospingono verso un orizzonte curvato in una sorta di “ossessione per la vita”, come qualcuno ha detto. C’è tuttavia qualche elemento che può essere utilizzato in positivo per tentare di innescare processi che alla lunga possano risultare risolutivi. Il saggio ne indica almeno due. Il primo riguarda aspetti di contenuto e di intenzionalità, ed orienta il discorso verso i fini; il secondo attiene per molti versi al metodo, ma riconduce pur’esso a considerazioni di tipo valoriale.
