Modeling the potential distribution of the invasive golden mussel Limnoperna fortunei in the Upper Paraguay River system using limnological variables

The invasive golden mussel, Limnoperna fortunei (Dunker, 1857), was introduced into the La Plata River estuary and quickly expanded upstream to the North, into the Paraguay and Paraná rivers. An ecological niche modeling approach, based on limnological variables, was used to predict the expansion of the golden mussel in the Paraguay River and its tributaries. We used three approaches to predict the geographic distribution: 1) the spatial distribution of calcium concentration and the saturation index for calcium carbonate (calcite); 2) the Genetic Algorithm for Rule-Set Production (GARP) model; and the 3) Maximum Entropy Method (Maxent) model. Other limnological variables such as temperature, dissolved oxygen, pH, and Total Suspended Solids (TSS) were used in the latter two cases. Important tributaries of the Paraguay River such as the Cuiabá and Miranda/Aquidauana rivers exhibit high risk of invasion, while lower risk was observed in the chemically dilute waters of the middle basin where shell calcification may be limited by low calcium concentrations and carbonate mineral undersaturation

(a cura di Monica Palmerini) Del tradurre il 'Don Quijote'. Prospettive sulla traduzione nel IV centenario della morte di Miguel de Cervantes, Roma, Aracne editrice, Dialogoi-Ispanistica, vol. 23

Il volume nasce nell’ambito delle celebrazioni per il IV centenario della morte di Miguel de Cervantes, proponendo come argomento di riflessione la traduzione nel e del Don Chisciotte. Da una parte, la traduzione è il veicolo fondamentale che ha reso possibile l’incredibile viaggio del capolavoro di Cervantes tra epoche storiche, culture e lingue diverse, trasformandolo in patrimonio dell’umanità. Dall’altra, il tradurre funge da meccanismo centrale nella genesi stessa del Quijote e costituisce una dimensione privilegiata di interpretazione dell’opera. Dalla combinazione di queste due prospettive prende forma un omaggio alla figura e all’opera di Cervantes che ne sottolinea, attraverso lo sguardo sul tradurre, la profonda attualità. L’opera si costruisce nell’intreccio di contributi di esperti, spagnoli e italiani, di varie discipline (letteratura spagnola, filologia romanza, lingue e cultura classiche, linguistica, comunicazione, teoria e pratica della traduzione) e attraverso il dialogo tra italiano e spagnolo, che si alternano come lingua dei vari articoli
