Inventaire des proies ingérées par le marbré Lithognathus mormyrus (Linnaeus, 1758) (pisces : perciformes : sparidae) dans la baie d'Alger et d' Annaba ArchiMer
Harchouche, K; Maurin, C; Quero, Jean-claude.
At the time of a survey of the biology of Lithognathus mormyrus and its feeding ecology and dynamies, in the region of Algiers and Annaba, preys ingested by this species were determined from stomach contents. Food was composed entirely of benthic organisms. It has been counted more than 45 species-preys distributed in 9 taxonomic classes. The quantitative analysis of these preys and the variation of the food regime according to a certain number of parameters were treated. The young individuals fed on small Tellinids bivalves and adults, on Crustaceans Amphipods, Cumaceans, Decapodes, Molluscs, sea urchins and Polychaetes. The feeding of this fish was rich and varied in preys species and little among them were preferential. The three main sources of food...

Processus Gravitaires et Évaluation de la Stabilité des Pentes : Approches Géologique et Géotechnique. Application à la marge algérienne et à l'effondrement de l'aéroport de Nice en 1979 ArchiMer
Dan, Gabriela.
The present work consists of two areas of interest: the Algerian margin and the area affected by the 1979 Nice slide. The first scientific survey, MARADJA, took place in 2003 in order to characterize the Algerian margin from a morpho-sedimentary point of view and to map the presence of mass-wasting deposits. Based on other two scientific surveys, PRISMA and MARADJA 2, the mechanical and physical properties of the Algerian sediment were defined. The geotechnical properties were used to identify the triggering mechanisms of the observed mass-wasting deposits and to assess the present-day slope stability. The main results are: • The sedimentary processes are clearly influenced by the morphology of the margin, which is controlled by the tectonics. The...
