De Smet K. 2003. Cheetah in and Around Hoggar National Park in Central Sahara (Algeria)
de Smet K. 2003. Cheetah in and around Hoggar National Park in Central Sahara (Algeria). Cat News 38(Spring):22-4. Keywords: 1DZ/Acinonyx jubatus/cheetah/Hoggar NP/National Park/North Africa/prey/Sahara/status/ territorial behaviour Abstract: According the studies conducted in the late' 80s, in 2000 and in 2003, the cheetah is largely widespread in the Hoggar Mountains (Algeria) and its surroundings. Their numbers have probably risen since 2000. The potential preys of the cheetah are abundant. However, the cheetah is often killed by the Tuaregs despite their protection status. Cheetahs are reported to move on constantly from one valley to another, but have a territorial behaviour. The absence of competitors allows cheetah to hunt its preys without facing their robbery. The situation may be good in the Tassili Mountains too. D'après les études menées à la fin des années 80, en 2000 et en 2003 le guépard est largement répandu dans les montagnes du Hoggar (Algérie) et ses environs. Leur nombre a probablement augmenté depuis 2000. Les proies potentielles du guépard sont abondantes. Cependant, malgré son statut d'espèce protégée, le guépard est souvent tué par les Touaregs. D'après les observations, les guépards se déplacent constamment d'une vallée à l'autre, mais gardent un comportement territorial. L'absence de compétiteurs permet au guépard de chasser ses proies sans avoir à faire face à leur vol. La situation doit également être bonne dans les montagnes du Tassili.

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). -

(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.

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%. -
