Lasting Impression

The longue durée of human activity on the island of Pantelleria represents an important locus of ancient cultural interaction in the Strait of Sicily. This narrow channel in the central Mediterranean has played a major and continuous role in human relations between Italy, Sicily and North Africa since the Neolithic period. Use or control of the Pantelleria has been pivotal for a number of cultures over time, each leaving a lasting impression on the landscape and the people of the island (Figure 1). The volcanic geology of Pantelleria has determined the shape of its landscape and is responsible for the creation of the collapsed-caldera basin and lake that form the study area of this project. The Brock University Archaeological Project at Pantelleria (BUAPP) is working in the Lago di Venere area, examining past human activity on the north-eastern lake shore. A previous project in the Lago di Venere area (1998–2002) interpreted the site as a Punic and Roman sanctuary (Audino & Cerasetti 2004; Cerasetti 2006). Our project complements this and other archaeological investigations of the island's classical past, including the ongoing excavations on the Acropolis, near the main harbour, which have revealed the remains of the island's Punic and Roman centre (Schäfer et al. 2015).

AbstractThe revision of the Paliurus spina-christi dominated vegetation of Europe is presented here. The study area includes the north-eastern part of Iberian Peninsula and Provence to the west, and spreads through the Apennine Peninsula to the Balkan Peninsula and up to Eastern Mediterranean areas. The phytosociological releves of Paliurus spina-christi dominated vegetation found in the literature for these European territories were gathered together in a phytosociological table. Floristic analysis, cluster analysis, and indirect gradient analysis were performed to determine the similarities and differences between the different Paliurus spina-christi dominated communities and their correlations with the main bioclimatic indices described in the literature. The various analyses highlight the existence of nine different associations (one of which is described here for the first time) that are attributed to different syntaxonomic levels.In the conclusion, a syntaxonomical scheme is proposed that classifies the European vegetation of shrublands in the class Rhamno-Prunetea which includes the class Paliuretea. Currently, we recognized three orders within this class: Prunetalia spinosae for central and south-central Europe; Pyro spinosae-Rubetalia ulmifolii within the Temperate oceanic bioclimate of the sub-Mediterranean variant; Paliuretalia spinae-christi with a central Mediterranean and sub-Mediterranean distribution, that mainly occurs in the central-eastern Mediterranean (Southern Apennine Peninsula) and the Balkans.Finally, a part of the shrub vegetation dominated by Paliurus spina-christi is referred to the class Quercetea ilicis, the order Pistacio lentisci-Rhamnetalia alaterni, the alliance Oleo sylvestris-Ceratonion siliquae and the suballiance Oleo sylvestris- Paliurenion spinae-christi that refers to thermophilous shrub communities that require high edaphic humidity.

For the first time, an otolith shape analysis was used to investigate the stocks of saddled bream (Oblada melanura, Linnaeus, 1758) in three fishing zones along the Tunisian coast (Bizerte, Kélibia and Sayada). Otolith shape analysis was used on 30 otoliths for each site, sampled during the spawning period. Using elliptic Fourier descriptors (EFD) the quantization of the shape otolith was investigated by SHAPE and multivariate statistical procedures. Considering the environmental and the genotypic aspects, the preliminary results of the otolith shape analysis showed dissimilarity in silhouette of otoliths of saddled bream stocks collected from the north (Bizerte), the north-east (Kélibia) and the east (Sayada) of the Tunisian coast. Therefore, these three groups could be considered as three sub-units of the Tunisian stock, which should be managed separately.

This study investigates gravity-induced landforms that populate the North-Eastern coast of Malta. Attention is focused on tens of persistent joints and thousands of boulders associated with deep-seated gravitational slope deformations (DGSDs), such as lateral spreads and block slides. Lateral spreads produce deep and long joints, which partially isolate limestone boulders along the edge of wide plateaus. These lateral spreads evolve into large block slides that detach thousands of limestone boulders from the cliffs and transport them towards the sea. These boulders are grouped in large slope-failure deposits surrounding limestone plateaus and cover downslope terrains. Gravity-induced joints (n = 124) and downslope boulders (n = 39,861) were identified and categorized using Google Earth (GE) images and later validated by field surveys. The datasets were digitized in QGIS and stored using ESRI shapefiles, which are common digital formats for storing vector GIS data. These types of landslides are characterized by slow-moving mechanisms, which evolve into destructive failures and present an elevated level of risk to coastal populations and infrastructure. Hundreds of blocks identified along the shore also provide evidence of sinkholes; for this reason, the paper also provides a catalogue of sinkholes. The outputs from this research can provide coastal managers with important information regarding the occurrence of coastal geohazards and represent a key resource for future landslide hazard assessment.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.
