Study of the Interannual Rainfall Variability in Northern Algeria Etude De La Variabilite Inter-Annuelle Des Pluies De L'algerie Septentrionale
Revue scientifique et technique. LJEE N°23. Décembre 2013 STUDY OF THE INTERANNUAL RAINFALL VARIABILITY IN NORTHERN ALGERIA ETUDE DE LA VARIABILITE INTER-ANNUELLE DES PLUIES DE L'ALGERIE SEPTENTRIONALE Mohamed MEDDI. École Nationale Supérieure d’Hydraulique, Blida, LGEE. [email protected] Samir TOUMI . École Nationale Supérieure d’Hydraulique, Blida, LGEE. ABSTRACT : The work presented here focuses on the inter-annual variability of annual rainfall in Northern Algeria. This work is carried out by using the coefficient of variation (the ratio between the standard deviation and the average). We will try to show areas of low, medium and high variations in Northern Algeria. In order to do this, we use 333 rainfall stations spread over the entire study area, with a measurement period of 37 years (1968/2004). The contrast of rainfall spatial and temporal distribution has been demonstrated by studying the sixteen basins, as adopted by the National Agency of Water Resources. The high spatial variability characterizes the basins of the High Plateaus of Constantine and Chot El Hodna. Keywords: Northern Algeria - annual Rainfall - inter-annual variability - coefficient of variation RESUME : Nous présentons dans cet article une étude de la variabilité interannuelle des pluies annuelles en Algérie septentrionale. Ce travail a été réalisé en utilisant le coefficient de variation (le rapport entre l'écart-type et la moyenne). Nous essayerons de montrer les zones à faible, moyenne et forte variations dans le Nord de l'Algérie. Pour se faire, nous avons utilisé 333 postes pluviométriques réparties sur l'ensemble de la zone d'étude avec une période de mesure de 37 ans (1968/2004). -

Geological Quarterly, 2004, 48 (1): 89–96 Reptile tracks (Rotodactylus) from the Middle Triassic of the Djurdjura Mountains in Algeria Zbigniew KOTAÑSKI, Gerard GIERLIÑSKI and Tadeusz PTASZYÑSKI Kotañski Z., Gierliñski G. and Ptaszyñski T. (2004) — Reptile tracks (Rotodactylus) from the Middle Triassic of Djurdjura Mountains in Algeria. Geol. Quart., 48 (1): 89–96. Warszawa. In 1983, during stratigraphic investigations in the Djurdjura Mountains, vertebrate tracks were discovered in the Middle Triassic Haizer–Akouker Unit at the Belvédère (Bkherdous) locality in Algeria. The footprints are about 2 cm long and consist of impressions of four clawed digits (I–IV), plus a reverted digit V. Manus imprints were overstepped by those of the pes. Originally interpreted as lizard footprints, they have been recently diagnosed as Rotodactylus cf. bessieri Demathieu 1984. In the current literature, Rotodactylus trackmakers are regarded as a group closest to dinosaurs among stem archosaurs. The footprints demonstrate a terrestrial sedimentary re- gime in the Maghrebids area during the ?late Anisian.

Il s’agit de marno-calcaires contenant une riche faune de bivalves/huîtres, échinides, gastéropodes, ostracodes, foraminifères benthiques et planctoniques. Les céphalopodes se trouvent dans le membre inférieur (niveau à ammonites, n° 6). L’étude des ammonites a permis d’établir une attribution biostratigraphique précise. La zone à Mortoniceras pricei est mise en évidence grâce à la détermination d’un Elobiceras (Craginites) sp. aff. newtoni Spath, 1925. Une interprétation paléoenvironnementale et paléogéographique est proposée grâce à l’étude des différents faciès présents dans cette formation.

Operation Serval. Analyzing the French Strategy Against Jihadists in Mali
ASPJ Africa & Francophonie - 3rd Quarter 2015 Operation Serval Analyzing the French Strategy against Jihadists in Mali LT COL STÉPHANE SPET, FRENCH AIR FORCE* imilar to the events that occurred two years earlier in Benghazi, the crews of the four Mirage 2000Ds that took off on the evening of 11 January 2013 from Chad inbound for Kona in central Mali knew that they were about to conduct a mis- sion that needed to stop the jihadist offensive to secure Bamako, the capital of Mali, and its population. This time, they were not alone because French special forces Swere already on the battlefield, ready to bring their firepower to bear. French military forces intended to prevent jihadist fighters from creating a caliphate in Mali. They also knew that suppressing any jihadist activity there would be another challenge—a more political one intended to remove the arrows from the jihadists’ hands. By answering the call for assistance from the Malian president to prevent jihadists from raiding Bamako and creating a radical Islamist state, French president François Hollande consented to engage his country in the Sahel to fight jihadists. Within a week, Operation Serval had put together a joint force that stopped the jihadist offensive and retook the initiative. Within two months, the French-led coalition had liberated the en- tire Malian territory after destruction of jihadist strongholds in the Adrar des Ifoghas by displaying a strategy that surprised both the coalition’s enemies and its allies. On 31 July 2014, this first chapter of the war on terror in the Sahel officially closed with a victory and the attainment of all objectives at that time. -

Algerian Inuleae Tribe Species Distribution Modeling Under Influence of Current and Future Climate Conditions

This study aims to predict the impact of bioclimatic variables in current and future climatic scenarios on the distribution of Inuleae tribe species. Modeling the distribution of 30 species of the Inuleae tribe in Algeria was carried out with a maximum entropy model. Two models with 99 occurrence points were obtained with mean values of Area Under a Curve (AUC) of 0.987±0.01 and 0.971±0.02, reflecting excellent predictive power. Three bioclimatic variables contributed mainly to the first model and four - to the second one with cumulative contributions of 83.8% and 79%, respectively elucidating differences between species of the two major climatic zones in Algeria: the Tell and the Sahara. Two-dimensional niches of Algerian Inuleae species allowed to distinguish these two groups with the distribution of 18 Tell species, characterized by high rainfall (14-18°C, 400-1000 mm) and the other 12 species – distributed in hot and dry environments (17-24°C, 20-200 mm). Modeling the distribution under future conditions showed that habitats of the Saharan region would be much less suitable for these species with a variation in the annual mean temperature increase up to 20% and a decrease in annual precipitation, which could raise to 11 and 15%. -
