SUMMARY According to a recent catalogue and other new contributions, the vascular flora of Sicily consists of more than 3,250 specific and intraspecific taxa. Among them endemic taxa, including those very local and threatened, amount to 16%. Noteworthy are both adventitious and naturaliz…

[On the presence of Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae) in the Nature Reserve of Isola delle Femmine (Palermo, Sicily, Italy)] The presence of a living population of Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae), endemic species of the coastal strip of the Palermo Mountains (Sicily), from Isola delle Femmine or Isola di Fuori (Isola delle Femmine Nature Reserve) is confirmed
THE GARGANO TERRE ROSSE INSULAR FAUNAS: AN OVERVIEW
2010
After forty years from its discovery, the history of the field surveys and of the researches on the fossiliferous deposits on Gargano is briefly reported. The Gargano fauna belongs to the Abruzzo-Apulian Palaeobioprovince (including also Scontrone and Palena, Abruzzo). The fossil assemblage comprehends all the classes of terrestrial vertebrates: Reptilia, Amphibia, Aves and Mammalia. The faunal composition is unbalanced and presents the features of a typical insular endemic fauna. The bulk of the assemblage is composed of small mammals and birds. Based on literature, we report the most characteristic features, phylogenetic relationships, and evolutionary remarks on a list of mammals, focusi…
Mammals of Italy: An annotated checklist
2019
Checklists represent a basic tool for conservation and management of regional faunas. However, our knowledge on species composition in a territory changes over time due to species movements across borders, extinctions, introductions, as well as to new taxonomic evidence. We aimed to provide the most updated data on native and non-native species of mammals occurring, or that used to occur until recently, on the Italian political territory and seas. The checklist only includes species whose taxonomic status was explicitly agreed in the most recent peer-reviewed literature and based on the most updated taxonomic approaches. For each species, we provided the following information: scientific an…
The Mediterranean dwarf shubs: origin and adaptive radiation
2006
Basing on literature data, a synthesis on the morphologic, anatomic and physiologic adaptations of the Mediterranean dwarf shrubs is outlined. Three different functional types can be recognized: saltbushes, thermo-xerophilous fire-resistant dwarf shrubs and orophilous cushion-shrubs. The thermo-xerophilous fire-resistant dwarf shrubs mainly derive from the Mesogean flora and differentiated after the beginning of the Oligocene, and especially from the Pliocene, in the coastal regions around the Tethys Sea, as the result of a local adaptive radiation triggered by the shifting from subhumid to semiarid climatic conditions at the boundary between the tropical and the temperate zone. For the oth…
New records of amphipod crustaceans along the Israeli Mediterranean coast, including a rare Mediterranean endemic species, Maera schieckei Karaman & …
2020
A survey has been carried out at four Israeli rocky sites to evaluate the diversity of the amphipod fauna on various hard substrates, still scarcely monitored, as potential pabulum for amphipod crustacean species. A survey of shallow rocky reefs along the Mediterranean coast of Israel recovered 28 species and integrated the Amphipoda checklist for the country ofIsrael with 12 newly-recorded species. Such renewed national list includes Maera schieckei Karaman & Ruffo, 1971, a rare species endemic to the Mediterranean Sea, recorded here for the first time from the southern Levant Basin. The species, described from specimens collected in the Tyrrhenian Sea in 1970, has been only record…
Microevolution in the sicilian shrew crocidura sicula (mammalia, soricidae) tested by rapd-pcr fingerprinting
1997
Genetic variation in samples of the endemic Crocidura sicula living in Sicily and in two surrounding small islands, Marettimo and Ustica, was analysed by Random Amplified Polymorphic DNA fingerprinting (RAPD) and compared to morphometrics and external phenotypes. Molecular variation in the random sample of 99 DNA fragments of the Ustica shrews, showing.a melanic fur and a size-shape variation in skull morphometrics, is of comparable size to that of the of northwestern and northeastern samples Sicily (Tufanio and Madonie). In the Marettimo shrews, bicoloured (grey and white) animals like those coming from Sicily and presenting a significant reduction in body-size and skull morphometrics, mol…

2014
Orobanche cohenii a new species belonging to Orobanche sect. Trionychon is described and illustrated from Mt. Hermon, Israel. Its relationships with the other species of Orobanche sect. Trionychon occurring in this area are examined.

Preliminary insights into the molecular barcoding data of Turraea socotrana (Meliaceae) from Socotra (Yemen)
2020
The relationship of two geographically and ecologically separated populations of Turraea socotrana Styles and F. White (Meliaceae), a vulnerable and scattered shrub from the island of Socotra (Yemen), was explored using preliminary molecular data. The nuclear ribosomal ITS region was used to screen the level of genetic divergence of T. socotrana from ecologically distant localities in comparison to a few other species of Turraea and closely related genera. The individuals from the inland (Diksam) differed from the western coastal ones (Ma’alah) by vegetative characters and by the rbcL gene. This may be due to the fact that the population from Ma’alah grows on lithosoil slopes directly expos…
