Genetic variation was surveyed at nine microsatellite loci and the mitochondrial control region (868 bp) to test for the presence of genetic stock structure in young-of-the-year Atlantic bluefin tuna (Thunnus thynnus thynnus) from the Mediterranean Sea. Bluefin tuna were sampled over a period of 5 years from the Balearic and Tyrrhenian seas in the western basin of the Mediterranean Sea, and fro...

Atlantic bluefin tuna (ABFT) are highly valued and heavily exploited, and critical uncertainties regarding their population structure hinder effective management. Evidence supports the existence of two breeding populations of ABFT; a western population in the Gulf of Mexico and an eastern population in the Mediterranean Sea; both of which migrate and mix in the North Atlantic. Conventional tagg...

Most warm-adapted Central European species are thought to have survived ice ages exclusively in Mediterranean refugia. During recent years, this point of view has been questioned. Therefore, we tested the hypothesis that extra-Mediterranean refugia also played a role in warm-adapted insect species and selected the chalk-hill blue, Polyommatus coridon. We sequenced two mitochondrial loci (COI, C...

Greece is located between parallels 340 and 420 of the Northern Hemisphere. It is a country in southeastern Europe, situated on the southern tip of the Balkan Peninsula, bordering the eastern Mediterranean. The country covers an area of about 131,000 km, the coastline of which extends to 13,676 km and it corresponds to half of the total Mediterranean coastline. The Greek islands are estimated a...

Eighteen specimens of palpigrades captured in seven caves in the provinces of Castellon and Valencia in eastern Spain are studied. We describe and illustrate three new species and a new subspecies: Eukoenenia valencianus sp. nov., Eukoenenia montagudi sp. nov., Eukoenenia sendrai sp. nov. and Eukoenenia patrizii iberica ssp. nov. The Iberian fauna now comprises nine species that we place into t...

[1] Water column stratification increased at climatic transitions from cold to warm periods during the late Quaternary and led to anoxic conditions and sapropel formation in the deep eastern Mediterranean basins. Highresolution data sets on sea-surface temperatures (SST) (estimated from U37 k0 indices) and dO of planktonic foraminifer calcite (dOfc) across late Pleistocene sapropel intervals sh...

We use monthly data of aerosol optical thickness (AOT) from the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the 7 NASA Terra and Aqua satellites for the ten-year period (2001 -2010) in order to determine seasonal variations of Saharan dust transport over the Mediterranean towards Europe. The maxima of AOT are used to visualize the transport paths. Saharan dust reaches Europe ...

Recent studies have focused on the relationship between the marine fauna of the Eastern Atlantic and the Mediterranean Sea, but within the Atlantic, little is known about genetic relationships between populations of the Macaronesian islands. In this study, we tested whether the paleo-climatology and paleo-oceanography of the region could predict the genetic relationships among three Eastern Atl...

The POSEIDON weather forecasting system became operational at the Hellenic Centre for Marine Research (HCMR) in October 1999. The system with its nesting capability provided 72-h forecasts in two different model domains, i.e. 25and 10-km grid spacing. The lower-resolution domain covered an extended area that included most of Europe, Mediterranean Sea and N. Africa, while the higher resolution d...

abstract this research attempts to investigate the role of the blocking systems in surface cyclogenesis over eastern mediterranean sea; but particular attention is focused on the flood of iran during march 2000 over western states of iran as: hamadan, ilam, lorestan, kermanshah, kurdestan, zanjan, ghazvin.the data used for this research includes upper level and mean sea level pressure charts ev...
