The medieval botanical lexicon in some falconry works in romance languages
2018
Durant l’edat mitjana, els tractats de falconeria es dedicaven, entre altres assumptes, a descriure els símptomes i malalties que patien les aus, i oferien com a cures pal·liatives diferents remeis terapèutics a partir de les plantes medicinals. Aquest treball presenta un inventari de termes botànics que registrem en una obra del segle xv, el Llibre de Caça, a més dels vocables corresponents que hem trobat en quatre obres de falconeria medieval de tantes altres llengües romàniques: portuguès, castellà, francès i italià. De cada terme exposem quines propietats curatives tenien, el nom científic de la planta de què procedeix, l’etimologia del mot, juntament amb l’ètim estàndard actual. Finalm…

Dal martire al cacciatore. Traduzioni intersemiotiche dell’eroismo antimafia
2022
Questo contributo muove da un'analisi comparativa tra la biografia di Alfonso Sabella "Cacciatore di mafiosi" (Mondadori, 2008) e le prime due stagioni della fiction Rai "Il Cacciatore" (2018-2020), tratte dal libro. L'obbiettivo è problematizzare questo processo di traduzione intersemiotica alla luce dell'evoluzione dei modelli d'eroismo dei personaggi. Nel saggio, ricolleghiamo questa evoluzione a una riflessione più generale sulla natura transmediale della memoria collettiva, sempre più legata allo spettacolo del passato costruito dai media, che ibridano tra loro generi diversi. Per situare le tendenze contemporanee della memoria dell'eroismo antimafia all'interno di una genealogia pià a…
Ecological specialization to fluctuating resources prevents long-distance migratory raptors from becoming sedentary on islands
2013
[Background]: The adaptive transition between behavioral strategies, such as the shift from migratoriness to sedentariness, remains an outstanding question in evolutionary ecology. Density-dependent variation in the age of first breeding has been proposed as a feasible mechanism through which long-lived migratory birds with deferred sexual maturity should become sedentary to persist on islands. Although this pattern seems to hold for most raptors and herons, a few exceptions have been identified. One of these exceptions is the Eleonora's falcon, a long-distance migratory bird, which shows one of the most peculiar adaptations in the timing of reproduction and food requirements among raptors.…
Spatial segregation of home ranges between neighbouring colonies in a diurnal raptor
2018
AbstractEnhancement of information transfer has been proposed as a key driver of the evolution of coloniality. Transfer of information on location of food resources implies that individuals from the same colony share foraging areas and that each colony can be associated to a specific foraging area. In colonial breeding vertebrates, colony-specific foraging areas are often spatially segregated, mitigating intercolony intraspecific competition. By means of simultaneous GPS tracking of lesser kestrels (Falco naumanni) from neighbouring colonies, we showed a clear segregation of space use between individuals from different colonies. Foraging birds from different neighbouring colonies had home r…
Scavengers on the move: behavioural changes in foraging search patterns during the annual cycle
2013
Background: Optimal foraging theory predicts that animals will tend to maximize foraging success by optimizing search strategies. However, how organisms detect sparsely distributed food resources remains an open question. When targets are sparse and unpredictably distributed, a Lévy strategy should maximize foraging success. By contrast, when resources are abundant and regularly distributed, simple Brownian random movement should be sufficient. Although very different groups of organisms exhibit Lévy motion, the shift from a Lévy to a Brownian search strategy has been suggested to depend on internal and external factors such as sex, prey density, or environmental context. However, animal re…
Baucina-Monte Falcone 2014, indagini nella necropoli.
2016
The aim of this report is to present the results of archaeological samples, executed in order to contrast illegal researches on a necropolis at Baucina, in the northwestern part of Sicily, where Punic, Greek and indigenous traditions coexisted, in a relationship which is the focus of our ongoing investigation. We collected an archeological dataset, whose interpretation is detecting an articulated situation where the interaction between three different ethnic groups gave as result the variety of rituals. The future excavations of the site could increase the perception of this interaction, for a period in which Greeks and Punics designed their spheres of influence of the territories within th…

L’immagine dei Normanni di Sicilia nella letteratura latina del XII secolo
2016
La dominazione normanna della Sicilia e dell'Italia meridionale, fra XI e XII secolo, è stata letta e interpretata in vario modo dagli scrittori contemporanei, sia quelli di parte bizantina, sia quelli occidentali. In questo saggio, dopo una breve premessa concernente i principali fatti storici e le relative fonti bizantine, ci si concentra sulla disamina di alcuni fra i principali scrittori e poeti che, tra la fine dell'XI e tutto il XII secolo, si sono occupati della dominazione normanna di Sicilia, cercando di individuare e di illustrare, caso per caso, la visione che essi ebbero dei Normanni conquistatori. Si discorre qui, nell'ordine, di Amato da Montecassino, Goffredo Malaterra, Gugli…
Social phenotype extended to communities: expanded multilevel social selection analysis reveals fitness consequences of interspecific interactions.
2014
In social species, fitness consequences are associated with both individual and social phenotypes. Social selection analysis has quantified the contribution of conspecific social traits to individual fitness. There has been no attempt, however, to apply a social selection approach to quantify the fitness implications of heterospecific social phenotypes. Here, we propose a novel social selection based approach integrating the role of all social interactions at the community level. We extended multilevel selection analysis by including a term accounting for the group phenotype of heterospecifics. We analyzed nest activity as a model social trait common to two species, the lesser kestrel (Falc…
