No full textNel contributo esploriamo mondi di umani insieme ad altri animali,
nel vasto e articolato testo culturale (post)minerario del Belgio e del Limburgo Olandese e nei suoi archivi (post)memoriali: un testo fatto di testi memoriali multilingui, fotografie, canzoni, di opere finzionali (anche per l’infanzia) e arti figurative. Non proponiamo un bestiario, ma una minima etnografia multispecie di realtà complesse e contraddittorie, ricche di significati: un racconto – o meglio un intreccio di racconti verbali e non
Prey of the Short-eared Owl (Asio flammeus) in a Pampas grasslands area of Argentina
No full textWe describe the prey of the Short-eared Owl in a Pampas grassland area of Argentina on the basis of pellets occasionally collected (N = 10). We found a high proportion of small mammals within samples (80% by number and 97% by biomass). Pellets also contained a very small number of insects and an avian prey. Prey spectrum of this owl species in our study site was similar to those described on other previous studies. Presence of rodents that typically inhabit native grasslands in the study area suggests that the Short-eared Owl could be exploiting less human-impacted areas as hunting habitats.Fil: Baladron Felix, Alejandro Victor.

Xerse. Cavalli/Lully
No full textDossier numérique réalisé à l'occasion de la première recréation moderne du 'Xerse' de Francesco Cavalli et Jean-Baptiste Lully (Paris 1660) à l'Opéra de Lille (octobre 2015)First performed in Venice on January 12, 1655 in the Santi Giovanni e Paolo theatre, Xerse is one of Venetian master Francesco Cavalli’s most successful works, after Egisto (1643) and Giasone (1649), and is the result of a collaboration between Cavalli and a promising young librettist, Nicolò Minato. The work was an immediate success and was reprised in the largest Italian cities (Milano, Rome, Genoa, Naples, etc.) during the second half of the century, and in a revised form in Paris in 1660, for the wedding of Louis XIV and Maria Theresa of Spain.The revival of Xerse in Paris in 1660 takes place during the celebration of Louis XIV and Maria Theresa of Spain’s marriage. Since the 1640’s, Cardinal Mazarin had been very involved in the efforts to establish Italian opera at the French court, and he had hoped to invite Francesco Cavalli to Paris to mark this event, since Cavalli was already a famous composer at this time and the author of more than 20 operas.In 2015, the Parisian version of Xerse was revived. This work, unique in the context of seventeenth-century Italian opera, is produced by the Lille Opera and its coproducers, the Centre de musique baroque de Versailles and the Caen Theatre. Guy Cassiers directed, with musical direction by Emmanuelle Haïm, leading the “Concert d’Astrée” ensemble.Créé à Venise le 12 janvier 1655 au théâtre Santi Giovanni e Paolo, Xerse compte parmi les titres à succès de Francesco Cavalli, après Egisto (1643) et Giasone (1649). Fruit de la collaboration entre le maître vénitien et un jeune librettiste prometteur, Nicolò Minato, l’œuvre remporta un succès immédiat et fut reprise dans les principales villes italiennes (Milan, Rome, Gênes, Naples, etc.) pendant la seconde moitié du siècle. Parmi les reprises, on compte également la représentation dans une version remaniée à Paris, en 1660, pour le mariage de Louis XIV avec Marie-Thérèse d’Autriche.La reprise de Xerse à Paris en 1660 s’inscrit dans le cadre des célébrations pour le mariage de Louis XIV et Marie-Thérèse d’Autriche. Le cardinal Mazarin, très impliqué depuis les années 1640 dans des tentatives d’implanter l’opéra italien à la cour de France, avait souhaité, pour marquer cet événement, inviter Francesco Cavalli à Paris, à cette date compositeur renommé et déjà auteur de plus de vingt opéras.En 2015, la version parisienne de Xerse renaît sur la scène. L’Opéra de Lille, en coproduction avec le Centre de musique baroque de Versailles et le Théâtre de Caen, recrée cette œuvre unique dans le contexte de l’opéra italien du XVIIe siècle, avec une mise en scène de Guy Cassiers et sous la direction musicale d’Emmanuelle Haïm, à la tête du Concert d’Astrée
Comparison of the diet of two bird-eating raptors, the Aplomado Falcon (Falco femoralis) and the Cinereous Harrier (Circus cinereus), in the Pampean Region of Argentina
No full textWe studied the diet and hunting activity of two bird-eating raptors, the Aplomado Falcon (Falco femoralis) and the Cinereous Harrier (Circus cinereus), in Mar Chiquita Biosphere Reserve, Argentina. Prey was identified by analyzing pellets collected during December 2005. The Cinereous Harrier showed a higher consumption of birds than the Aplomado Falcon (92,3% vs 67,9% of total prey, respectively), and a reverse tendency was observed for the biomass contribution (26% vs 88%). In addition, these raptors showed differences in hunting techniques: the Aplomado Falcon used a sit-and-wait strategy, whereas the Cinereous Harrier used an active-search strategy. Our results suggest that both factors, the use of different prey and hunting modes, could be important for trophic niche segregation between these two bird-eating raptors.Fil: Baladrón, Alejandro V..

Elio Vittorini e la Conversazione in USA
No full textElio Vittorini never went to America. Nonetheless, he fostered and signed translations; he prepared the anthology Americana; he contributed to the fortune of US writers in Italy; he maintained a correspondence with authors such as Ernest Hemingway and publishers such as James Laughlin. In June 1948 he wrote to Renato Mieli, editor-in-chief of l’Unità in Milan, explaining his refusal to go overseas for a reportage. His motivations entailed his activity as writer: “I could author a sort of Conversazione in Sicilia focused on the US: a Conversazione in USA”. His memory journey to his home soil moulds every other tale of travel, geographical contours tend to overlap, and he even turns down actual travel. Essentially, it is a literary dialogue: every different geographical place becomes a tool to rethink one’s own identity, especially on a political basis. This is an obvious trait both of his work as translator during the twenty-year fascist rule and of his claim for autonomy with respect to the Communist orthodoxy. This autonomy is even more necessary after the Politecnico events, because, as Vittorini writes in his letter to Mieli, “I should be free to ‘understand’, rather than having to ‘prove’ my ‘already achieved’ understanding”
Diet of the variable hawk (Geranoaetus polyosoma) in grasslands and periurban zones of the pampean region of Argentina
No full textSe estudió la dieta del Aguilucho Común (Geranoaetus polyosoma) durante el período no reproductivo en dos áreas contrastantes, un pastizal natural y una zona periurbana ubicadas en el sudeste de la Región Pampeana (Argentina), con el objetivo de evaluar si los hábitos tróficos de esta rapaz cambian de acuerdo al ambiente. La dieta del Aguilucho Común estuvo compuesta exclusivamente por micromamíferos en ambos sitios, aunque los ítem presa consumidos difirieron entre hábitats. El ratón de campo (Akodon azarae) fue la presa dominante en pastizales naturales, mientras que el tuco-tuco (Ctenomys talarum) fue la presa principal en zonas periurbanas. El Aguilucho Común realizó un alto consumo de roedores grandes en pastizales (83,3% menores a 30 g de peso promedio) en comparación con zonas periurbanas (61,5% mayores a 90 g de peso promedio). Los resultados evidenciarían la plasticidad de esta rapaz a cambiar su comportamiento alimentario dependiendo de las condiciones locales.We studied the diet of the Variable Hawk (Geranoaetus polyosoma) during non-breeding season in two contrasting areas, a natural grassland and a periurban zone located in the southeast of the Pampean Region (Argentina), in order to address if food habits of this raptor change according to location. The diet of the Variable Hawk was composed exclusively of small mammals in both sites, although prey items were different between habitats. Akodon azarae was the dominant prey in grasslands, whereas Ctenomys talarum was the main prey in periurban zones. The Variable Hawk showed a high consumption of small rodents in grasslands (83.3% smaller than 30 g of mean mass) in comparison to periurban zones (61.5% larger than 90 g of mean mass). Our results would be evidencing the plasticity of this raptor to change its feeding behavior depending on the local conditions.Fil: Baladron Felix, Alejandro Victor.

Reproductive behavior of White-tailed Kites (Elanus leucurus) in the Pampas of Argentina
No full textThe White-tailed Kite (Elanus leucurus) is a raptor that has been less studied in the Neotropics than in the Nearctic region, especially in relation to its reproductive behavior. In this study, we report information about the phenology and activity patterns of this raptor at the Pampas of Argentina. We found that White-tailed Kites have a prolonged breeding season, from October to May. Time-activity budgets of mating pairs indicated a pronounced division of roles in parental care between sexes. Females devoted most of their time to nest construction, incubation and chick care (80% of total time) and males to food provisioning and vigilance (70% of total time). We registered 11 cases of prey transfer from the male to the female. In four cases the transfer occurred in flight and in the remaining seven cases while individuals were perched. Our results agree with general patterns on breeding behavior of White-tailed Kites from North America, suggesting a consistent behavioral pattern throughout the species´ distribution.Fil: Baladrón, Alejandro Victor.

Social networks and ornithology studies: an innovative method for rapidly accessing data on conspicuous bird species
No full textWe developed an innovative method for finding individuals of a conspicuous species in complex urban habitats. The aim of this study was to detect as many burrowing owl nests as possible in order to develop an ecological and behavioral study. We performed an online survey through the social network, Facebook. The results of this survey allowed us to detect and locate 36 new burrowing owl nests. We conclude that developing online surveys through social networks is an innovative and cost-effective method to obtain information about bird locations, and can complement traditional methods such as field surveys.Fil: Cavalli, Matilde.

Burrowing owls eavesdrop on southern lapwing's alarm calls to enhance their antipredatory behaviour
No full textEavesdropping is a widespread behaviour among animals, providing the receiver with valuable information to assess the habitat, resources or threats. This kind of behaviour has been reported for the burrowing owl (Athene cunicularia), which in its northern range lives in close association with fossorial mammals and eavesdrops on their alarm calls as indicators of risk. In their southernmost range, burrowing owls do not associate with mammals, but they are often found sharing foraging and nesting patches with the southern lapwing (Vanellus chilensis), a noisy, territorial and aggressive plover species. We designed a field experimental study aimed at determining if burrowing owls are able to use lapwing calls as indicator of potential risk. We exposed focal owls to a sequence of sounds including lapwing alarm calls, and biological and non-biological controls, and registered their response as alert or relax behaviours. Linear mixed modeling showed that owls increased their alert behaviour in response to lapwing alarm calls but not in response to control treatments. In addition, owls’ response was consistent between habitats (rural and urban) and seasons (breeding and non-breeding). Our results suggest that eavesdropping is a generalized strategy of burrowing owls to acquire environmental information throughout its distribution range.Fil: Cavalli, Matilde.

Microscale nest-site selection by the Burrowing Owl (Athene cunicularia) in the pampas of Argentina
No full textHabitat modifications have led many bird species to occupy areas with different characteristics, including human-altered landscapes. In this study, we analyzed how land use influences the nest-site selection at the microscale level by Burrowing Owls (Athene cunicularia) breeding in vegetated sand dunes, periurban areas, and agroecosystems in the Pampas of Argentina. We compared the characteristics of the nest site (percentage of open space) and the nest patch (distance to conspecific nests, tall vegetation and perches and number of perches) within and among the three land-cover types. In addition, we evaluated the breeding performance (nesting success and productivity) of owls nesting in these land-cover types. We found that nest microsite variables did not vary between owl-occupied and owl-unoccupied sites within nest patches, but they differed among land-cover types. Although nest patches differed in their availability of perches at each land-cover type, distance from the nest to the nearest perch did not vary between them. Distances to tall vegetation and to conspecific nests were highly variable and did not differ among land-cover types. Our results indicate that Burrowing Owls that inhabit the Pampas used a variety of land-cover types for nesting and showed little selectivity of nest sites and nest patches, thus reinforcing the idea that they are habitat generalists.Fil: Martinez, Guadalupe.
