PRESENZA DI SPECIE CRIPTICHE BRACHIDONTES VARIABILIS-PHARAONIS (BIVALVIA: MYTILIDAE) RIVELATA DALL’ANALISI DEL 28S-rDNA

DNA-Barcoding to solve the tricky case of co-occuring Sabellaria (ANNELIDA) species in the Mediterranean Sea
2015
Intraspecific morphological variation of key taxonomic features is probably responsible for frequent misidentification of Sabellaria (Lamarck, 1818) species. This is the case of Sabellaria alcocki Gravier, 1906 whose Mediterranean records probably refer to juveniles of S. spinulosa (Leuckart, 1849). We hereby provide molecular tools (DNA barcoding) to improve correct delimitation of the Mediterranean species of this genus.
Zamenis lineatus (Camerano, 1891) (Saettone occhirossi), Z. longissimus (Laurenti, 1768) (Saettone comune).

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…

Presence and biodistribution of perfluorooctanoic acid (PFOA) in Paracentrotus lividus highlight its potential application for environmental biomonit…

AbstractThe first determination of presence and biodistribution of PFOA in ninety specimens of sea urchin Paracentrotus lividus from two differently contaminated sites along Palermo’s coastline (Sicily) is reported. Analyses were performed on the sea urchins’ coelomic fluids, coelomocytes, gonads or mixed organs, as well as on seawater and Posidonia oceanica leaves samples from the collection sites. PFOA concentration ranged between 1 and 13 ng/L in seawater and between 0 and 794 ng/g in P. oceanica. The analyses carried out on individuals of P. lividus from the least polluted site (A) showed PFOA median values equal to 0 in all the matrices (coelomic fluid, coelomocytes and gonads). Conver…

Ecomorphological variation within and among the two marine species of genus Salaria: Salaria basilisca and Salaria pavo (Perciformes: Blenniidae)
2022
In order to highlight the variation of the form due to the presence of different ecological factors, we investigated in this paper the morphological variation between and within the two marine species Salaria basilisca and S. pavo. This study was based on two approaches, the Truss network and the geometric morphometric and involved specimens of both species divided into marine and lagoon samples. The two approaches yielded complementary results showing clear morphological discrimination of the two species Thus, S. basilisca is distinguished by a higher depth and length as well as a higher head with a compressed snout compared to S. pavo which has a shortened body, a lower head and a slightl…

Morphological variation of the newly confirmed population of the javelin sand boa, Eryx jaculus (Linnaeus, 1758) (Serpentes, erycidae) in Sicily, Ita…
2019
The presence of the Javelin sand boa in Sicily has recently been confirmed. Here the morphological characters and sexual dimorphism of the Sicilian population of Eryx jaculus are presented. Seven meristic and six metric characters in 96 specimens from Sicily were examined. The results show that tail length, snout-vent length, the distance between nostrils and the number of ventral and subcaudal scales are different between sexes. The characters found in the Sicilian population of the Javelin sand boa resemble those of the African population (ssp. jaculus) rather than the Eurasian population (ssp. turcicus), but biomolecular studies are necessary to understand its taxonomic identity.
