Obsidian samples from Monte Arci in Sardinia (Italy) have been characterized by their minor and trace element concentration
in order to find discriminating parameters useful to provenance the prime matter of obsidian artifacts. Obsidian samples were
collected both at the SA, SB and SC outcrops and far away from them. All samples were submitted to INAA. The trace element
concentration appears to be very useful to discriminate the three flows. Multivariate statistical analysis confirms the satisfactory
distinction between the three sources. The assignment of the samples collected far away from outcrops to a specific flow (SC)
validates the hypothesis that obsidian blocks might have been washed out by alluvial events.

The Mediterranean is one of the major biodiversity hotspots of the world. It has been identified as the “core” of the speciation process for many groups of organisms. It hosts an impressive number of species, many of which are classified as endangered taxa. Climate change in such a diverse context could heavily influence community composition, reducing ecosystems resistance and resilience. This study aims at depicting the distribution of nine orchid species in the island of Sardinia (Italy), and at forecasting their future distribution in consequence of climate change. The models were produced by following an “ensemble” approach. We analysed present and future (2070) niche for the nine species, using Land Use and Soil Type, as well as 8 bioclimatic variables as predictors, selected because of their influence on the fitness of these orchids. Climate change in the next years, at Mediterranean latitudes, is predicted to results mainly in an increase of temperature and a decrease of precipitation. In 2070, the general trend for almost all modelled taxa is the widening of the suitable areas. However, not always the newly gained areas have high probability of presence. A correct interpretation of environmental changes is needed for developing effective conservation strategies.

Obsidian samples from the Tokaj Mountains (Hungary) and from the neighbouring Zemplin Hills (Slovakia) were analysed by instrumental
and epithermal neutron activation analysis for obtaining a “fingerprint” for discrimination of potential natural sources of
raw material that would permit tracing the origin of archaeological obsidian artefacts. These techniques fully discriminate
the Zemplin Hills sources (Carpathian I, eastern Slovakia) and the Tokaj Mountain sources (Carpathian II, north-eastern Hungary)
as well as these Central European sources from those already studied of the Mediterranean basin and adjacent regions.

The choice of stress resistant and highly adaptable species is a fundamental step for landscaping and ornamental purposes in arid and coastal environments such as those in the Mediterranean basin. The genus Tamarix L. includes about 90 species with a high endurance of adversity. We investigated the water relations and photosynthetic response of Tamarix arborea (Sieb. ex Ehrenb.) Bge. var. arborea and T. parviflora DC. growing in an urban environment. Both species showed no evidence of drought or salt stress in summer, and appeared to follow two strategies with T. arborea var. arborea investing in high carbon gain at the beginning of the summer, and then reducing photosynthetic activity at the end of the season, and T. parviflora showing lower but constant levels of photosynthetic activity throughout the vegetative season. For landscaping and ornamental purposes, we suggest T. arborea var. arborea when a fast-growing, high-cover species is necessary, and T. parviflora when less-invasive species are required.

Thirty-seven episodes of dust intrusion were observed between February 12, 1991 and August 31, 2000 in the Hungarian atmosphere
and found to be of Saharan origin. They have been assigned to typical source areas in Northern Africa selected by systematic
investigations related to the Mediterranean Basin. Elemental concentrations and regional signatures deduced from PIXE analysis,
total suspended particle mass, and black carbon mass have been measured on dust samples collected in Debrecen, Hungary. These
data combined with Aerosol Index data, and dust plume axes obtained from TOMS data from NASA satellites were used for assigning
the most probable source areas of the dust transported to the sampling site. Our data and conclusions are in accordance with
other published investigations on the predominant role of Saharan dust emission in building up the aerosol load of the global

Tomato crop in the Mediterranean Basin has been recently affected by the exotic pest Tuta absoluta (Meyrick), which is difficult to control due to its high reproduction rate and potential to develop resistance to insecticides. In this paper, the suitability and effectiveness of three predatory phytoseiid mites Cydnoseius negevi (Swirski and Amitai), Neoseiulus barkeri (Hughes) and Amblyseius largoensis (Muma), an indigenous species, were evaluated on larvae of T. absoluta under laboratory conditions. First instar larvae of T. absoluta proved to be possible food source for tested phytoseiid mites under laboratory conditions.
Females of C. negevi, A. largoensis and N. barkeri were able to feed and sustain oviposition on unfed, first instar larvae of T. absoluta. A diet of insect larvae provided the shortest oviposition period and adult longevity of C. negevi and A. largoensis, while N. barkeri showed the longest corresponding periods. The total and daily number of insect larvae consumed was significantly higher in N. barkeri than in A. largoensis and C. negevi. Likewise, N. barkeri laid significantly higher number of eggs (23.6 eggs / female) than that deposited by C. negevi and A. largoensis (2.5 and 3.9 eggs / female). The sex ratio of the progeny was female biased and ranged: (females / total=0.62-0.68%) when insect larvae were provided for females of C. negevi, A. largoensis and N. barkeri.
Guest Editors of this Special Chapter and the Conference Organisers are looking
forward to meeting you at the

Izmir ‘The pearl of the Aegean’
is the third most populous city of Turkey and the country’s largest
port after Istanbul. It is located on the Aegean Sea near the Gulf of Izmir.
The former Smyrna is one of the oldest cities of the Mediterranean basin,
established in the 3rd millennium B.C. Impressive
civil work of Greek architecture, synagogues, early Christian and Islamic
buildings are preserved in the town and in the near surrounding. Modern Izmir
also incorporates world-famous ancient cities like Ephesus, Pergamon and Sardis.
IZMIR INSTITUTE OF TECHNOLOGY
was established in 1992 as
the third University in Izmir. There are 115 teaching staff, 403 research
assistants, and about 2000 students in the University. The University has
Faculties of Science, Engineering and Architecture. The 31st International
Vacuum Microbalance Techniques Conference will be held during September 2007
in the Department of Chemical Engineering. The Department has three professors,
three associate professors, and 9 assistant professors. The main research
