Abstract. Ectoenzymatic activity, prokaryotic heterotrophic abundances and production were determined in the Mediterranean Sea. Sampling was carried out sub-surface, deep chlorophyll maximum layer (DCM), core of Levantine intermediate waters deeper part mesopelagic layers. Michaelis–Menten kinetics assessed using a large range concentrations fluorogenic substrates (0.025 to 50 µM). As consequen...

The invasion of Red Sea organisms through the Suez Canal, known as “Lessepsian migration” (after Ferdinand de Lesseps, the Frenchman who directed the canal’s construction), has profoundly modified the ecosystem of the Eastern Mediterranean. This migration, the result of major man-made changes in the area, has given us a unique opportunity to study the process of invasion and colonization by tro...

While Modern Standard Arabic is the formal spoken and written language of the Arab world, dialects are the major communication mode for everyday life; identifying a speaker’s dialect is thus critical to speech processing tasks such as automatic speech recognition, as well as speaker identification. We examine the role of prosodic features (intonation and rhythm) across four Arabic dialects: Gul...

Abstract. Ocean deoxygenation is a rising threat to marine ecosystems and food resources under present climate warming conditions. Organic-rich sapropel layers deposited in the Mediterranean Sea provide natural laboratory study processes that have controlled changes seawater oxygen levels recent geological past. Our based on three sediment cores spanning last 10 000 years located bathymetric tr...
