Status, distribution and conservation of Kentish plover Charadrius alexandrinus (Aves, Charadriiformes) in Sicily

2021

The Kentish Plover Charadrius alexandrinus is a sen sitive species whose national breeding population has been undergo ing a sharp decrease, up to 50%, in 2010 compared to the previous decade. Due to the lack of updated data and fragmented knowledge about its current status and distribution in Sicily, a specific and accu rate monitoring of this species was carried out during the years 2018 and 2019. About 230 km of coastline and 64 UTM squares 10x10 km were investigated during the breeding seasons, and a total of 205-287 pairs have been estimated for the whole region, distributed in 41 UTM squares (including the island of Favignana). Pairs are mainly concen trated in the complex of “Saline …

Timing and patterns of the ENSO signal in Africa over the last 30 years: insights from normalized difference vegetation index data.

2014

Abstract A more complete picture of the timing and patterns of the ENSO signal during the seasonal cycle for the whole of Africa over the three last decades is provided using the normalized difference vegetation index (NDVI). Indeed, NDVI has a higher spatial resolution and is more frequently updated than in situ climate databases, and highlights the impact of ENSO on vegetation dynamics as a combined result of ENSO on rainfall, solar radiation, and temperature. The month-by-month NDVI–Niño-3.4 correlation patterns evolve as follows. From July to September, negative correlations are observed over the Sahel, the Gulf of Guinea coast, and regions from the northern Democratic Republic of Congo…

First records of complete annual cycles in water rails Rallus aquaticus show evidence of itinerant breeding and a complex migration system

2020

Abstract In water rails Rallus aquaticus, northern and eastern populations are migratory while southern and western populations are sedentary. Few details are known about the annual cycle of this elusive species. We studied movements and breeding in water rails from southernmost Norway where the species occurs year-round. Colour-ringed wintering birds occurred only occasionally at the study site in summer, and vice versa. Geolocator tracks revealed that wintering birds (n = 10) migrated eastwards in spring to breed on both sides of the Baltic Sea, whereas a single breeding bird from the study site wintered in north Italy. Ambient light records of geolocator birds further indicated that all …

The diet of Saker Falcon Falco cherrug overwintering in the Mediterranean (Sicily)

2014

The winter diet of Saker Falcon Falco cherrug in the Mediterranean basin is unknown. Thanks to satellite tracking of two individuals from Hungary to Sicily, during winters 2012-13 and 2013-14 we identified the roost and collected 40 pellets. Pellet analysis allowed identification of 124 prey belonging to 29 taxa. Saker Falcons during winter shift their alimentation to insects and birds, with respect to mammals in the breeding season, plundering from small beetles to rabbits. Insects, especially Orthoptera and Coleoptera, were the most frequent prey in both years, totalling the 66.9% of remains. Among vertebrates the Saker Falcons preyed upon birds (21.77%), mammals (5.65%) and reptiles (4.8…

Quantifying Irrigated Winter Wheat LAI in Argentina Using Multiple Sentinel-1 Incidence Angles

2022

Synthetic aperture radar (SAR) data provides an appealing opportunity for all-weather day or night Earth surface monitoring. The European constellation Sentinel-1 (S1) consisting of S1-A and S1-B satellites offers a suitable revisit time and spatial resolution for the observation of croplands from space. The C-band radar backscatter is sensitive to vegetation structure changes and phenology as well as soil moisture and roughness. It also varies depending on the local incidence angle (LIA) of the SAR acquisition’s geometry. The LIA backscatter dependency could therefore be exploited to improve the retrieval of the crop biophysical variables. The availability of S1 radar time-series data at d…

Citizen science project to monitor wildlife: a first census of wintering Booted Eagle Hieraaetus pennatus in Sicily

2022

Citizen science can represent an effective tool for large- scale data collection and can be used to improve scientific knowledge and define species distribution ranges before proper planning of related conservation strategies. A regional census of wintering Booted Eagle Hieraaetus pennatus in Sicily, never achieved before, was organized by GAM (Gruppo Aquila Minore - Booted Eagle Group) on 12 Janu- ary 2020, involving 90 people from several organizations. A total of 112 wintering individuals have been recorded for the whole region, col- lecting related data about their colour morph, habitat preference and altitude. A regional estimate of 180-220 wintering individuals was cal- culated, also …

Campus Asia “Cinema Paradise” 2021. “Above the clouds”: Un progetto temporaneo per la Valle di Bolognetta

2021

In the frame of the international winter school organized by Campus Asia, the Valley of Bolognetta has been chosen by the LabCity Architecture group as the official site for an architectural competition. On the 30th anniversary of the Academy Award to Maestro Giuseppe Tornatore, Campus Asia promoted “Cinema Paradise” as main theme to design an architectural project that is envisioned as strictly connected to the people and to the environment. The project “Above the cloud”, presented by LabCity Architecture Team from the University of Palermo, joins nature and architecture through the design of a performative event.

Da «Nina» a «Belisa»: contagi veneziani (1788-1794)

2008

Giovanni Paisiello's "Nina o sia La pazza per amore" was one of the greates operatic successes of the late Eighteenth Century. The article studies its circulation in the Venetian area, as well as the reactions it produced as documented in theorical writings and newspapers. Moreover, the model of mixed dramaturgy exemplified by "Nina", characterized by the alternation of spoken dialogues and musical numbers, influenced some Italian authors. "Belisa ossia La fedeltà riconosciuta" by Alessandro Pepoli and the German composer Peter von Winter is one of the most interesting results of this experimentation, and can be considered as a sort of new "Nina" for the Venetian stage.

Analysis of early strains of the norovirus pandemic variant GII.4 Sydney 2012 identifies mutations in adaptive sites of the capsid protein.

2014

AbstractGlobal surveillance for norovirus identified in 2012 the emergence of a novel pandemic GII.4 variant, termed Sydney 2012. In Italy, the novel pandemic variant was identified as early as November 2011 but became predominant only in the winter season 2012–2013. Upon sequencing and comparison with strains of global origin, the early Sydney 2012 strains were found to differ from those spreading in 2012–2013 in the capsid (ORF2) putative epitopes B, C and D, segregating into a distinct phylogenetic clade. At least three residues (333, 340 and 393, in epitopes B, C and D, respectively) of the VP1 varied among Sydney 2012 strains of different clades. These findings suggest that the spread …
