Is Citizen Science a valid tool for monitoring alien species in Marine Protected Areas?
2020
We report on our experience of NIS monitoring within the Egadi Islands MPA and at Pianosa Island National Park of Tuscan Archipelago through Citizen Science projects The Projects Caea cdacea Egadi Islands and Aliens in the Sea allowed to gather useful information on the distribution and colonisation strategies of NIS and cryptogenic species within the Egadi Islands MPA The project Percorsi nel bluBlue Paths allowed to register the first record of two cryptogenic species, Aa dacea Rang, and Pec gbbe H Milne Edwards, , at Pianosa Island As in MPAs the protection does not hinder the introduction and spreading of NIS, we expect they are likely to continue to arrive and expand in the absence of …
A review on the animal xenodiversity in Sicilian inland waters (Italy)
2015
This paper reviews the available knowledge about faunal xenodiversity in Sicilian inland waters (Italy). The aim is to provide an updated checklist and bibliography of those non-indigenous species (NIS) which occur in the island, and to identify possible threats to its native biological diversity. Data were collected through an extensive literature search which encompassed also local journals, books, congress abstracts, and other grey literature. All the collected data were critically revised and, when possible, verified by consulting available collections or through dedicated sampling surveys. Only those data contained in reports indicating precise occurrence localities, which were confirm…
How do non-indigenous species affect native species and habitats?
Biological invasions are a key driver of global change, affecting biodiversity and natural ecosystem functioning. Non-indigenous species (NIS) with significant established and expanding populations have the potential to become invasive, with serious environmental, socio-economic, and/or human health consequences. Mediterranean Islands (including Marine Protected Areas “MPAs”), important hotspots of biodiversity, are particularly vulnerable to NIS invasions. Understanding the effects of NIS species on biodiversity, as well as their current distribution and expansion trends, is therefore critical for creating effective conservation strategies. Here, we present three different case studies fro…
Searching for the competitive ability of the alien seagrass Halophila stipulacea with the autochthonous species Cymodocea nodosa
2023
The tropical seagrass Halophila stipulacea (Forsskål) Ascherson, 1867 entered in the Mediterranean Sea through the Suez Canal more than 100 years ago. In coastal-marine ecosystems the spatial niche of H. stipulacea is often overlapped with that of native Mediterranean Sea seagrasses and therefore it might out-compete them. Aiming to better understand its invasiveness potential, we monitored a Southern Mediterranean shallow coastal-marine water habitat from August 2010 to August 2011, where H. stipulacea co-occurred with the native seagrass Cymodocea nodosa (Ucria) Ascherson, 1870. Besides, the year-round dynamics of H. stipulacea was also monitored in four periods. To test the hypothesis th…

Coinage and Indigenous Populations in Central Sicily
2015
The study of the coins found in the indigenous settlements of Caltanissetta province and the analysis of the related contexts of provenance, have highlighted that in these centers, still in the 4th century BC, the coin was considered a worthless piece of metal and that other bronze objects were used as medium of exchange. It is remarkable the discovery in this territory of three “mixed” hoards, including not only coins, but also of bronze scraps and small fragmentary objects. These elements seem to show a late achievement, among those communities, of an economy based on the exclusive use of coins, that was a peculiar expression of the Greek culture
Monete e spazi sacri: rinvenimenti monetali dai santuari dell’entroterra siciliano
2016
This paper analyzes the coins finds from the sacred area of the indigenous settlements of the Sicilian hinterland. In particular, these coins have been found in sites called Balate, Polizzello, Raffe, Sabucina and Vassallaggi. As, in most cases, the coins are accompanied by the data of excavation, it is possible to make hypotheses about the function carried out the coins within the sacred spaces. It is well known that the coin finds in sacred areas can not be interpreted only as votive offerings, as are also suitable for other readings that only the examination of the context can decode.
Depositi di valore e offerte ponderali per gli dei dalle aree sacre indigene della Sicilia
2021
The study analyzes five hoards from some indigenous centers of Sicily, paying particular attention above all to the methods of deposition and the context of discovery in order to advance reflections on their function and destination. Since these are complexes found in the vicinity or within sacred places, it is however possible to further circumscribe the interpretative possibilities. The scrap metal, in fact, as a form of accumulation of wealth, can act as a votive offering, probably cut to precise weight standards, or as a reserve of value of the sanctuary or even have the function of material used by foundries close to sacred places. Only the analysis of the context of discovery and the …
