Determination of Water-Soluble Trace Elements in the PM10 and PM2.5 of Palermo Town (Italy)
2022
This study contributes to the current knowledge on the solubility of trace elements in the atmospheric particulate matter of the urban area of Palermo. Daily sample filters of PM10 and PM2.5 were collected in monitoring stations within and outside the urban area, characterized by variable traffic density. The bulk of compositions in PM10 and PM2.5 were determined by ICP-MS. The water-soluble trace elements (WSTE) and major ion components of particulate matter were determined by ICP-MS and ion chromatography, respectively. A significant difference in the metals content was observed between the samples taken in urban areas and those from suburban areas. The calculated enrichment factor highli…
First finding in Sicily of Bidens subalternans (Asteraceae)
2017
It is reported the presence in Sicily of a new alien species destined to a progressive further spread in the Island. It is Bidens subalternans DC., an annual asteracea of American origin, already known in other Italian regions (Friuli Venezia Giulia, Lombardia, Marche, Lazio and Campania) and in other European countries (Belgium, Corse, Croatia, Cyprus, France, Germany, Great Britain, Montenegro, Republic of Serbia, Slovenia, Spain, Switzerland). The new locality, in Sicily, occurs along the roadside Monreale – Pioppo, south of the city of Palermo. In this station, B. subalternans is found together with B. pilosa subsp. minor and other indigenous and exotic nitrophilous taxa. The population…
ARE MARINE PROTECTED AREAS (MPAs) EFFECTIVE IN PROTECTING FROM INVASIVE SPECIES? THE CASE STUDY OF CAULERPA CYLINDRACEA SONDER (CAULERPALES, CHLOROPH…
2019
The main purpose of Marine Protected Areas (MPAs) is biodiversity conservation. The effects that invasive species have on MPAs, and vice versa, are still not completely known, even though their assessment is crucial for MPA management and conservation purposes. In this respect, monitoring plans are essential and the involvement of citizen scientists may be fundamental. Our experience of Caulerpa cylindracea Sonder 1845 monitoring within the Egadi Islands MPA highlighted that the alga is widespread within the MPA, mainly at Favignana Island, also threatening valuable habitats such as vermetid reef and coralligenous formations. Moreover, Favignana is the island of the Aegadian archipelago mos…

Hieracium racemosum subsp. lucanum (Asteraceae), a new hawkweed from southern Italy
2019
A new endemic taxon of Hieracium belonging to the H. racemosum aggregate is described from Basilicata (southern Italy) and named H. racemosum subsp. lucanum. Information on its morphology, distribution, ecology and taxonomic relationship is provided.

Strategie di gestione delle popolazioni di Calendula maritima Guss. (Asteraceae)
2011
Dopo avere brevemente esaminato la situazione in cui si trovano le popolazioni naturali di C. maritima, specie rara ed endemica della provincia di Trapani (Sicilia), si discute delle più opportune strategie di gestione al fine di assicurarne la conservazione. Vengono infine identificate le principali minacce e proposte le conseguenti necessarie azioni di tutela.
An updated overview of invasive Caulerpa taxa in Sicily and circum- Sicilian Islands, strategic zones within the NW Mediterranean Sea
2017
The spread dynamics of invasive Caulerpa taxa (i.e. Caulerpa cylindracea, C. taxifolia var. taxi- folia and C. taxifolia var. distichophylla) in Sicily and circum-Sicilian Islands, based on relevant publications, grey literature, unpublished data and in situ observations during the last 23 years, is presented here and discussed. Their known distribution is mapped. New records are also reported. Transport-stowaway is considered the most plausible vector of introduction of invasive Caulerpa in the area. The three invasive taxa showed different spread dynamics. Caulerpa cylindracea and C. taxifolia var. distichophylla, behaved as highly successful and fast-spreading taxa, i.e. as true invasive…
The role of Characeae in the communities of the vegetation class Potametea
2018
The stonewort vegetation is commonly classified into the phytosociological class Charetea fragilis F. Fukarek ex Krausch 1964; however, the Characeae are not exclusively found in vegetation stands ascribed to this class but also in other habitat types. In our preliminary investigations, we draw the attention to the relationship between the classes Charetea fragilis and Potametea pectinati Klika in Klika & Novák 1941 in some Sicilian biotopes. In some cases, the Charetea vegetation is ecologically and spatially distinct, although close, from that referable to the Potametea. In some other cases, one or more species of Characeae are structurally intrinsic to the vegetation of Potametea: on…
