New Mediterranean records of Trabutina mannipara (Hemprich & Ehrenberg 1829) (Hemiptera: Coccomorpha: Pseudococcidae)
2018
The occurrence of Trabutina mannipara (Hemprich & Ehrenberg, 1829) (Hemiptera: Coccomorpha) is reported for the first time at Linosa (Pelagian Islands, Sicily Channel, Italy) and Libya. T. mannipara was approved by USA authorities for release as biocontrol agents against invasive saltcedars. The potential impact of this species, that in the Mediterranean area showed to be occasionally invasive, is discussed.
Agronomic Evaluation and Chemical Characterization of Sicilian Salvia sclarea L. Accessions
2020
Clary sage (Salvia sclarea L.), known for its aromatic and medicinal properties, belongs to the Lamiaceae family. Although the species grows wild throughout Sicily, knowledge of its production and qualitative properties is limited. The aim of this study was to evaluate the agronomic behavior of the species over two years of testing and to characterize the chemical properties of its wild counterparts in order to identify the most promising accessions for cropping or for use in breeding programs. Tests were carried out during 2008, 2009, and 2010. During the first year, the plot was established. Subsequently, the main parameters for bio-agronomic evaluation were taken in 2009 and 2010. Regard…
Assessing the spatiotemporal persistence of fish distributions: a case study on two red mullet species (Mullus surmuletus and M. barbatus) in the wes…
2020
Understanding the spatiotemporal persistence of fish distributions is key to defining fish hotspots and effective fisheries-restricted areas (FRAs). Hierarchical Bayesian spatiotemporal models provide an excellent framework to understand these distributions, as they can accommodate different spatiotemporal behaviour in the data, primarily due to their flexibility. The aim of this research was to characterize the fundamental behavioural patterns of fish as persistent, opportunistic or progressive by comparing different spatiotemporal model structures in order to provide better information for marine spatial planning. To illustrate this method, the spatiotemporal distributions of 2 sympatric …

Properties of New Strawberry Lines Compared with Well-Known Cultivars in Winter Planting System Conditions
2017
In Southern Italy and Sicily, strawberry cultivation is dominated by international cultivars such as ‘Candonga Sabrosa’, ‘Florida Fortuna’, ‘Sabrina’ and ‘Sant Andreas’. The primary objective of our study was to compare the field performance of two experimental lines and four established cultivars in a Sicilian representative strawberry production area. The second objective was to compare the fruits physic-chemical nutraceutical characteristics of these genotypes in response to different postharvest fruit storage temperatures. A supporting genetic analysis, via SSR markers, was also performed in order to establish genotype correlations. Our study confirmed the high result of ‘Florida Fortun…
Species–area relationship and small-island effect of vascular plant diversity in a young volcanic archipelago
2021
International audience; Aims: Aeolian islands form an active volcanic archipelago. By using updated vascular plant checklists for islands and islets, we tested four hypotheses: (i) Island speciesarea relationship (ISAR) of alien species has lower c-and higher z-values than native species, (ii) islands with active volcanoes have lower species richness than expected for native and alien species, (iii) ISAR of native species shows lower c-and higher z-values than ISARs of Mediterranean land bridge archipelagos and (iv) species richness of smaller islets is independent of area.Location: Aeolian Archipelago, Mediterranean Basin.Taxon: Vascular plants, identified and named according to the Flora …
Boat anchoring on Posidonia oceanica beds in a marine protected area (Italy, western Mediterranean): effect of anchor types in different anchoring st…
2004
Seagrasses worldwide are noted for suffering from mechanical damage caused by boat anchoring. This is particularly so in sites highly frequented by boaters (marine protected areas or coastal urbanised areas). In the last decades, different strategies have been put into practice to reduce such impacts on seagrasses (i.e. by anchoring bans or by deploying boat moorings), More recently, in consideration that few marine protected area (MPA) management bodies or local administrations have the resources to enforce their anchorage regulations, the self-regulatory approach based on education and information of boaters has been preferred in several cases. At present, however, very little is known on…
Bayesian spatio-temporal approach to identifying fish nurseries by validating persistence areas
2015
Spatial and temporal closures of fish nursery areas to fishing have recently been recognized as useful tools for efficient fisheries management, as they preserve the reproductive potential of populations and increase the recruitment of target species. In order to identify and locate potential nursery areas for spatio-temporal closures, a solid understanding of species− environment relationships is needed, as well as spatial identification of fish nurseries through the application of robust analyses. One way to achieve knowledge of fish nurseries is to analyse the persistence of recruitment hotspots. In this study, we propose the comparison of different spatiotemporal model structures to ass…

Distribution, ecological role and symbioses of selected shrubby species in the Mediterranean Basin: a review
2020
Among the Mediterranean ecosystems, shrublands are a characteristic type of vegetation, widespread in different habitats. Owing to different factors such as the physiological, morphological, reproductive, phenological and regenerative properties, as well as the inter-intraspecific interactions, each shrubby species represents an important element within the plant community and plays a specific ecological role. In this review, attention was focused on the ecological functions and type of plant-microsymbiont interactions in respect of selected shrubby species within the Mediterranean Basin: Amelanchier ovalis, Astragalus nebrodensis, Crataegus laciniata, Lycium intricatum, Prunus spinosa and …
