Biologie Résumé : Aures is a region of eastern Algeria, characterized by its high mountains, vast plains, history, population and their customs and traditions. The strategic location of this region and the ancient scientific work provided by the researchers has been a motivation for conducting a comprehensive study on locusts.
due to the prospections carried out in the Aurès region in three sites at different altitudes:
Lazrou, Djerma and Hamla ranging from 800 m to 1200 m, we inventoried 21 locust species belonging to the families Pamphagidae, Pyrgomorphidae and Acrididae, and 60 plant species that have been interpreted using the phytosociological system.
At the local scale, variation in flora accounts for the greater diversity of Orthoptera in Djerma, but not the differences observed between Hamla and Lazrou. On a regional scale, climatic constraints expressed by the shortening of the high-altitude growing season explain the lower diversity of locusts in Hamla, through a counter-selection of taxa showing unsuitable life cycles. The mid-domain effect explains more than 50% of the variations in locust diversity, through direct and indirect actions on Locusts. Local and regional scales contribute in a complex way, as well as the effect of the field environment, to locust diversity.

BiologieTags : Aurès Apoidea distribution floral diversity الأوراس النحل البري التوزيع تنوع الأزهار Index. décimale : 570 Sciences de la vie. Biologie Résumé : Anthophorini and Eucerini, like the whole of Apoidea, occupy a key position in the ecosystems. They take part in a dominating way in pollination of the entomophilous plants.
They are particulary remarkable by their very targeted floral choices. Indeed, the majority of the species belonging to these tribes is polylectic even oligolectic. Unfortunaly, these tribes are very badly known. For an unspecified study applied, it was thus necessary to arry out a signifiant synthesis on the taxonomy and the biogeography of this group. From the many data resulting from the laboratory of Biosystematics and Ecology of Arthropods and and personal
collections, several mechanisms are built. First, a monograph of the species at regional level (Aures) is achieved. On the other hand, catalog is taken over the commonly recognized synonyms of different taxa. Turthermore, we studied the functional features on phenology of each species studied. At the end of this work, we collected 1525 specimens belonging to 68 species, 5 genus and 17 sub-genus of Anthophorini and Eucerini were listed on a regional
level, Eight species are new for our fauna. Thus Eucerini includes 62.36% of species diversity compared to anthophorini which represent only 37.64%. To understand their dynamic, distribution maps are realized. In the same way, their diversity centers were highlighted on several geographical and taxonomic levels. The world distribution of Apidae and richness of each biogeographic area (Ethiopian, East-Paleartic and West-Paleartic) are specified.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/MAG7164.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10449 Biogéographie des apidae (hymenoptera; apoidea) d’algérie et monographie des espèces d’eucerini et anthophorini dans la région des aurès.

ICP-M" Index. décimale : 540 Chimie et sciences connexes Résumé : Our goal in this work was to search the secondary metabolites of flavonoids type from two species from Asteraceae and Cistaceae families in order to search new natural compounds of biological interest. Thirteen (13) extracts from different species including twelve (12) from the Aures regions were subjected to a phytochemical screening. On the basis of these preliminary results, the phytochemical investigation of the aerial parts two species, Pulicaria inuloides and Cistus albidus from the Bechar and the Aures regions respectively was carried out. This approach allowed the isolation of twelve natural compounds, among which eleven flavonoids, one phenolic compound as well as two acetyl derivatives of one of the isolated compounds were characterized using spectroscopic methods such as UV-Visible, IR and NMR.
The biological activities in vitro (antioxidant and antibacterial activity) as well as the total phenolic and flavonoids compounds of the various extracts were discussed. We also reported the evaluation of the in vitro antiprotozoal activity of the two species Pulicaria inuloides and Cistus albidus against Leishmania amazonensis, Trypanosoma cruzi and Acanthamoeba castellanii str. Neff. The bioguided fractionation of the CHCl3 extract from the aerial part of P. inuloides leads to the isolation and characterization of quercetagetin-3,5,7,3'-tetramethylether as the active ingredient. Two acetylated derivatives were prepared from this natural compound and these three compounds were evaluated for their activities against the promastigote form of L. amazonensis.
All these compounds exhibited moderate leishmanicidal activity with IC50 values ranging from 0.234 to 0.484 mM and low toxicity to macrophage cells (CC50 ranging from 0.365 to 0.664 mM). This study reported the antiprotozoal evaluation of Pulicaria inuloides for the first time and the results show that this species can be considered as a source of anti-leishmanicidal agents. The bioguided fractionation of the active extract of CHCl3 from C. albidus against T. cruzi led to the isolation of two fractions F6,4 and F6,5 which showed also a potent activity up to 100 μg/ml. The bioguided fractionation of the active extract of AcOEt from the aerial part of C. albidus against A. castellanii led to the isolation of a fraction F14A which showed a significant activity up to 100 μg / ml. Fractions F6,4 ; F6,5 and F14A consists of product mixtures, which have not been separated.
We have also described the chemical compositions of the essential oils of Pulicaria inuloides and Cistus albidus. The major compounds of the species C. albidus are manool and 15,16-dinorlabd-8(20)- en-13-one whose skeleton of type labdane is a specific marker in this genus, these compounds are not described in samples from other regions and in particular in the Mediterranean regions (Spain and France) that appeared in the literature. The major compounds of the species Pulicaria inuloides are: δ- cadinene, α-muurolene, γ-cadinene, α-epi-cadinol and α-cadinol are not present in the other samples of Pulicaria inuloides from other areas published in the literature.
In this study, the mineral content (inorganic elements) of 21 isolated extracts of various aromatic species of the Sahara (P. inuloides) and the Aures region (Euphorbia helioscopia L., Peganum harmala L., Daphne gnidium L., Calendula algeriensis L., Bunium incrassatum L., Echinops ritro L. Marrubium deserti de Noè., Juniperus oxycedrus L., Juniperus phoenicea L., Marrubium vulgare L., Cedrus atlantica (Endl.) Manetti and Thymus algeriensis L.) were also determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and inductively coupled plasma mass spectroscopy (ICP-MS) . The results obtained showed higher concentrations of Ca, K, Mg, Na and S
(mg/kg) in the different plant extracts.
