Impacts of ambient temperature and clutch size on incubation behaviour onset in a female-only incubator songbird
2021
Ambient temperature is assumed to be the major cue used by passerines to synchronize their laying and hatching dates to the expected peak of prey availability. While laying eggs, females are still able to fine-tune their hatching date following increasing or decreasing patterns of ambient temperature, mostly via changes in incubation onse t. The onset of incubation behaviour in relation to the laying sequence could have later conse- quences for the duration of the incubation period and the extent of hatching asynchrony. Clutch size is also known to affect incubation patterns and might therefore condition potential responses to changing temperatures. In this study we assessed the association…
Observed heterospecific clutch size can affect offspring investment decisions.
2011
Optimal investment in offspring is important in maximizing lifetime reproductive success. Yet, very little is known how animals gather and integrate information about environmental factors to fine tune investment. Observing the decisions and success of other individuals, particularly when those individuals initiate breeding earlier, may provide a way for animals to quickly arrive at better breeding investment decisions. Here we show, with a field experiment using artificial nests appearing similar to resident tit nests with completed clutches, that a migratory bird can use the observed high and low clutch size of a resident competing bird species to increase and decrease clutch size and egg…
Multiple aspects of plasticity in clutch size vary among populations of a globally-distributed songbird.
2013
Plasticity in life-history characteristics can influence many ecological and evolutionary phenomena, including how invading organisms cope with novel conditions in new locations or how environmental change affects organisms in native locations. Variation in reaction norm attributes is a critical element to understanding plasticity in life history, yet we know relatively little about the ways in which reaction norms vary within and among populations. We amassed data on clutch size from marked females in eight populations of house sparrows (Passer domesticus) from North America and Europe. We exploited repeated measures of clutch size to assess both the extent of within-individual phenotypic …
In light of the ends. Copyright hysteresis and private copy exception after the British Academy of Songwriters, Composers and Authors (BASCA) and oth…
2015
In British Academy of Songwriters, Composers and Authors (BASCA) and others v Secretary of State for Business, Innovation and Skills, the High Court of Justice in matter of private copy exception provides the twofold prime opportunity to shed light on the state of the art of copyright in the UK and to flesh out the idea of 'legal hysteresis’. I support the reintroduction of the private copy exception, possibly in a less narrow fashion, and I explain the reasons why I am confident that my expectations will be fulfilled.

La Divette in Partenope: La prima esibizione napoletana di Yvette Guilbert
2020
Nel saggio viene discussa la prima esibizione napoletana di Yvette Guilbert, avvenuta nel 1897. Vengono messi a confronto e commentati testi di Guilbert e brani da giornali napoletani del tempo
Spunti di racconto in alcuni «Carmina Cantabrigiensia»
2015
The «Cambridge Songs» («Carmina Cantabrigiensia») are a collection of short Latin poems which we find in the lone manuscript Gg. 35 (Ca), housed in the Cambridge University Library. The manuscript itself was produced at the monastery of St. Augustine in Canterbury, in the middle of the XIth century, just before the Norman invasion of England. The best part of the poems of the «Cambridge Songs» probably derives from Germany and belongs to a period between IXth and XIth centuries. The 84 poems of the collection display a diversity of form, content and function. We can extricate praise poetry for kings and bishops, erotic verses, nature poems, and other sort of writing less easily classified. …
Lionardo Vigo, un pioniere dell'etnografia siciliana
2015
Il testo esamina la genesi della prima raccolta di canti popolari siciliani apparsa a stampa nel XIX secolo (prima edizione 1857, edizione riveduta e ampliata 1874). Le vicende biografiche dell’autore – Lionardo Vigo – si intrecciano con la storia politica e culturale della Sicilia, tra lotte risorgimentali e fase postunitaria. La sua Raccolta amplissima di canti popolari siciliani riflette il mutare delle ragioni politiche e i contrasti metodologici che nella seconda metà dell’Ottocento sorgono tra posizioni romantiche e nuovi orientamenti positivisti, destando intense reazioni tra gli studiosi contemporanei e alimentando un ampio dibattito nell’ambito della storiografia demoantropologica …
Forest management is associated with physiological stress in an old–growth forest passerine
2003
We investigated how physiological stress in an area-sensitive old-growth forest passerine, the Eurasian treecreeper (Certhia familiaris), is associated with forest fragmentation and forest structure. We found evidence that the concentrations of plasma corticosterone in chicks were higher under poor food supply in dense, young forests than in sparse, old forests. In addition, nestlings in large forest patches had lower corticosterone levels and a better body condition than in small forest patches. In general, corticosterone levels were negatively related to body condition and survival. We also found a decrease in corticosterone levels within the breeding season, which may have been a result …
Una sonora improvvisata. Dalla disputa sui canti di carcere di Pitrè e Lombroso all’oralità contemporanea
2022
In questo articolo illustreremo alcuni esempi di canti di carcere riportati da Giuseppe Pitrè e Cesare Lombroso che diedero spunto a una polemica scientifica tra i due studiosi. L’analisi delle varianti che stanno alla base della disputa scientifica dei due fondatori della Demopsicologia e dell’Antropologia criminale, momento fondamentale della storia degli studi antropologici italiani dell’Ottocento, ci permetterà di comprendere come la trasmissione orale della cultura sia ancora oggi permeata dalle stesse modalità performativa che affondano le loro radici nei racconti dei miti.
