BACKGROUND Several different classifications to characterize estuarine systems have been proposed. In this present paper, one of the most important estuaries in North Africa, the Oued Loukkos (Morocco), forms a case-study for proposing a systematic classification of this particular tidal estuary according to the vertical salinity gradient. FINDINGS This study, conducted using a CTD, shows tha...
In addition to the three so far known species of Prosopistoma Latreille, 1833 from West Palaearctic region, P. pennigerum (Müller, 1785), P. oronti Alouf, 1977 and P. orhanelicum Dalkıran, 2009, two new species are described based on larvae. Prosopistoma helenae sp. n. has been found in Iraq (Tigris River in Mosul) and Prosopistoma alaini sp. n. in Algeria (Oued Isser, Sidi Abdelli). Critical d...
Aim: This study was conducted on local bovine breed (black and white breed) in the east and the south of Algeria in order to reveal the influence of age, sex and altitude on the morphometry of red blood cells. Materials and methods: The animals were divided into three equal groups at different altitudes while the animals of each group include adult males, adult females, young males, young femal...
The Pleistocene Fluvial-lacustrine of Ait Hajji Formation is located in South East of Tiddas, and in the Quaternary deposits of the Moroccan Central Plateau. These outcrops represent on a geomorphosite of great importance for the study of geological heritage, and for a natural eco-tourism valorization in Morocco. For to aim a natural tourism promotion, for indigenous peoples, this geomorphosite...
The combination of detailed topographic leveling on the southwest segment of the El Asnam thrust fault with existing seismic and geologic data implies that the geometry of this fault involves shallow dipping flats and steep ramps. The fault appears to be growing along strike toward the southwest end, where the main shock initiated in 1980. From a depth of about 10 km, the main thrust appears to...
