The Hamburg/ESO R-process Enhanced Star survey (HERES)
2004
We report on a dedicated effort to identify and study metal-poor stars strongly enhanced in r-process elements ([r/Fe] > 1 dex; hereafter r-II stars), the Hamburg/ESO R-process Enhanced Star survey (HERES). Moderate-resolution (~2A) follow-up spectroscopy has been obtained for metal-poor giant candidates selected from the Hamburg/ESO objective-prism survey (HES) as well as the HK survey to identify sharp-lined stars with [Fe/H] < -2.5dex. For several hundred confirmed metal-poor giants brighter than B~16.5mag (most of them from the HES), ``snapshot'' spectra (R~20,000; S/N~30 per pixel) are being obtained with VLT/UVES, with the main aim of finding the 2-3% r-II stars expected to be a…

Mitochondrial sequence analysis of Salamandra taxa suggests old splits of major lineages and postglacial recolonizations of Central Europe from disti…
2000
Representatives of the genus Salamandra occur in Europe, Northern Africa and the Near East. Many local variants are known but species and subspecies status of these is still a matter of dispute. We have analysed samples from locations covering the whole expansion range of Salamandra by sequence analysis of mitochondrial D-loop regions. In addition, we have calibrated the rate of divergence of the D-loop on the basis of geologically dated splits of the closely related genus Euproctus. Phylogenetic analysis of the sequences suggests that six major monophyletic groups exist (S. salamandra, S. algira, S. infraimmaculata, S. corsica, S. atra and S. lanzai) which have split between 5 and 13 milli…
Nuovi dati sull’espansione dell’occhione Burhinus oedicnemus in Sicilia. Una riflessione sulla citizen science
2023
New data on the expansion of the Eurasian Thick-knee Burhinus oedicnemus in Sicily. A consideration of citizen science.In this work, we collected records of Eurasian Thick-knee observa-tions in Sicily by using scientific literature, citizen science programs, and social networks as data sources. The aims of this work is creat-ing a complete and up-to-date dataset, which also includes the authors’ targeted research in the field. As compared with records previously reported in literature, the data collected here, which cover the last fif-teen years, show a clear expansion trend for the Eurasian Thick-kneein Sicily. About one third of these new records come from Facebook groups dedicated to bio…
AGGIORNAMENTO SULLA DISTRIBUZIONE DEL SUCCIACAPRE Caprimulgidae) IN SICILIA CAPRIMULGUS EUROPAEUS (Aves
2021
Caprimulgus europaeus In recent years Update on the distribution of breeding Nightjar in Sicily. there have been numerous observations of Nightjar in areas where it had never previously been observed. In some cases the reason may be a deeper exploration, but in other cases the possible explanation is the expansion of the species. However, it is quite interesting the change in the habitat by this species. The present paper provides an update of its status based on data collected in the fifteen years following the publication of the last Sicilian Atlas of breeding birds.
ESPANSIONE DELLA RONDINE MONTANA PTYONOPROGNE RUPESTRIS (SCOPOLI) IN SICILIA (Aves Hirundinidae)
2021
Expansion of the Eurasian Crag Martin Ptyonoprogne rupestris (Scopoli) in Sicily (Aves Hirun dinidae). Data collected during the last fifteen years on the distribution of the Eurasian Crag Martin in Sicily and the comparison with those recorded in literature show an expansion trend for this species. While in the newly colonized areas the nesting sites have been observed mainly on natural habitats, where its occurrence was previously recorded the species shows and adaptation to exploit also anthropogenic habitats, such as buildings or other infrastructures.
