BOMBYLIIDAE (Diptera) FROM LAMPEDUSA ISLAND
2011
The authors report new records of Bombyliidae (Diptera) for Lampedusa Island discovered during field investigations carried out for a broader research project in the island. Data are updated to July 2010. Four species of Bombyliidae new for Lampedusa have been found, one of which has not been recorded for Sicilan dipterofauna. The present data bring to 60 the species of Diptera reported for Lampedusa Island.
SYRPHIDAE (DIPTERA) FROM LAMPEDUSA ISLAND
2010
Diptera of Lampedusa are poorly known, and the only published data are those of VENTURI (1960) and PISCIOTTA et al. (2008). In the present paper the authors report new records of Syrphidae (Diptera) for Lampedusa island discovered during field investigations carried out for a broader research project in the island. Data are updated to November 2009. Eleven species of Syrphidae new for Lampedusa have been found of which one is new for the Sicilian fauna.
Il supporto della SISV alla realizzazione di un manuale nazionale per il monitoraggio degli habitat della Direttiva 92/43/EEC in Italia
2016
A partire dall’entrata in vigore della Direttiva 92/43/EEC, la sorveglianza dello stato di conservazione degli habitat elencati nell’Allegato I ed il relativo monitoraggio periodico a intervalli di sei anni sono diventati un obbligo per tutti i paesi membri dell’UE, in base a quanto previsto negli Articoli 11 e 17. Nel 2011 è stato pubblicato un documento che fornisce le linee guida di riferimento europee per il monitoraggio di habitat e specie (Evans & Arvela 2011). Su questa base metodologica, la Società Italiana di Scienza della Vegetazione (SISV), avvalendosi di un ampio gruppo di soci esperti, ha avviato un dibattito interno su principi, criteri, parametri e strumenti per il monitoragg…
Validation of a mechanistic model for predicting fruit scab infection on different loquat cultivars
2017
[EN] Scab, caused by Fusicladium eriobotryae, is the main disease affecting loquat (Eriobotrya japonica) in the Mediterranean basin. A mechanistic epidemiological model developed in Spain to predict infection of loquat fruit by conidia was assessed in the main loquat cultivated area of Italy (Sicily). A 3-year study (2014-2016) was carried out in an experimental orchard on three loquat cultivars: Algerie, Peluche and San Filipparo. For each cultivar, output of the model was compared with observed scab development on fruits. The scab epidemics observed were different in different years and cultivars, representing a suitable data set for model validation. The model correctly predicted loquat …
Ecology and distribution of hypogeous fungi from Sicily (southern Italy).
2006
The distribution and ecology of 39 hypogeous and semi-hypogeous fungi is reported. Ten taxa, including the rare Fischerula macrospora, are new records for Sicily, while the presence of some species, previously reported by Oreste Mattirolo, is confirmed.
Land unit definition for potential distribution of endangered species
2010
In Europe several mapping techniques exist to lay out plant distribution. Most of them, however, are focused on actual and not on potential species distribution range. Spatial predictions become more important for rare and endangered taxa because their conservation is related to existing as well as potential biotopes. The large part of detailed distribution models applies advanced statistics on a large data-set of environmental variables. Data-input availability limits the choice of the prediction model for species distribution and application of results in a detailed scale. Distribution pattern accuracy determinates its applicability in environmental management (for tracing edges, defining…
Phytoplankton in extreme environments: importance and consequences of habitat permanency
2020
AbstractThere is hardly any sunshine exposed surface on this Earth, be it water or terrain, which would not support some biota. Still, many habitats offer harsh conditions requiring specialized physiological adaptations to survive. These environments are referred to as extremes; often inhabited by extremophilic organisms. In this review, characteristic species and assemblage properties of phytoplankton inhabiting extreme environments (especially lakes and pools where planktic life is potentially possible and independently of their origin) in terms of alkalinity, acidity, DOC, salinity, temperature, light and mixing regime will be outlined. Lakes characterized by more than a single extreme a…
The ethnobotany, phytochemistry, and biological properties of Nigella damascena – A review
2022
This review is a systematic scientific work on medicinal and traditional use, on the chemical composition of specialized metabolites, volatile and non-volatile, on aspects related to toxicology and phytotherapy of Nigella damascena L. The genus Nigella (Ranunculaceae) is distributed throughout the Mediterranean basin, extending to northern India, and has been divided into three sections. Nigella damanscena L. is traditionally used as an ingredient in food, for example, as flavouring agents in bread and cheese, but is also known in folk medicine, used to regulate menstruation; for catarrhal affections and amenorrhea; as a diuretic and sternutatory; as an analgesic, anti-oedematous, and antip…

Karyological data of four geophytes native to Tunisia
2021
Chromosome numbers were studied in four geophytes collected in Tunisia. Allium pallens was collected from Zembra island, N of Tunisia, while Drimia purpurascens, Oncostema peruvianum and Pancratium foetidum from continental Tunisia. The chromosome numbers found for Allium pallens, Drimia purpurascens, and Oncostema peruvianum coincides with the previous reports obtained from other Mediterranean populations. The chromosome number 2n = 22, found on material from Toujane is the first reported for Pancratium foetidum.
