As shown by the recent crisis, tax evasion poses a significant problem for countries such as Greece, Spain and Italy. While these societies certainly possess weaker fiscal institutions as compared to other EU members, might broader cultural differences between northern and southern Europe also help to explain citizens’ (un)willingness to pay their taxes? To address this question, we conduct laboratory experiments in the UK and Italy, two countries which straddle this North-South divide. Our design...
The complement system is an innate immunity effector mechanism; its action is antagonized by a wide array of pathogens and complement evasion determines the virulence of several infections. We investigated the evolutionary history of the complement system and of bacterial-encoded complement-interacting proteins. Complement components targeted by several pathogens evolved under strong selective pressure in primates, with selection acting on residues at the contact interface with microbial/viral proteins. Positively selected sites in CFH and C4BPA account...
Data from: Migratory connectivity and effects of winter temperatures on migratory behaviour of the European robin Erithacus rubecula: a continent-wide analysisRoberto Ambrosini, José Cuervo, Chris Du Feu, Wolfgang Fiedler, Musitelli Federica, Diego Rubolini, Beatrice Sicurella, Fernando Spina, Nicola Saino, Anders Møller & Federica Musitelli
1. Many partially migratory species show phenotypically divergent populations in terms of migratory behaviour, with climate hypothesized to be a major driver of such variability through its differential effects on sedentary and migratory individuals. 2. Based on long-term (1947–2011) bird ringing data, we analysed phenotypic differentiation of migratory behaviour among populations of the European robin Erithacus rubecula across Europe. 3. We showed that clusters of populations sharing breeding and wintering ranges varied from partial (British...
Data from: Sex-dependent carry-over effects on timing of reproduction and fecundity of a migratory birdNicola Saino, Roberto Ambrosini, Manuela Caprioli, Andrea Romano, Maria Romano, Diego Rubolini, Chiara Scandolara & Felix Liechti
Life of many organisms flows as a sequence of annual cycles. Timing of cyclical events is shaped by natural selection also via the domino effects that any life history stage has on the stages that follow. Such ‘carry-over effects’ have major consequences for evolutionary, ecological and demographic processes, but the causes that generate their individual-level variation, including the effect of sex, are poorly understood. We used light-level geolocators to study carry-over effects on the year-round...
Data from: Antipsychotic dose mediates the association between polypharmacy and corrected QT intervalCorrado Barbui, Irene Bighelli, Giuseppe Carrà, Mariasole Castellazzi, Claudio Lucii, Giovanni Martinotti, Michela Nosè, Giovanni Ostuzzi & Giovanni Targher
Antipsychotic (AP) drugs have the potential to cause prolongation of the QT interval corrected for heart rate (QTc). As this risk is dose-dependent, it may be associated with the number of AP drugs concurrently prescribed, which is known to be associated with increased cumulative equivalent AP dosage. This study analysed whether AP dose mediates the relationship between polypharmacy and QTc interval. We used data from a cross-sectional survey that investigated the prevalence of QTc lengthening...
Sex allocation theory predicts that parents are selected to bias their progeny sex ratio (SR) towards the sex that will benefit the most from parental quality. Because parental quality may differentially affect survival of sons and daughters, a pivotal test of the adaptive value of SR adjustment is whether parents overproduce offspring of the sex that accrue larger fitness advantages from high parental quality. However, this crucial test of the long-term fitness consequences of sex...
