Index. décimale : 570 Sciences de la vie. Biologie Résumé : Through a 3-year survey of 9 stations in North East of Algeria, we recorded 16 species of grasshopper belonging to the family Pamphagidae. The National Park of Belezma, near Batna city, appears to be the richest region for this family, with 10 species. Notably, Paracinipe sulphuripes, only known from Djelfa, is present at Belezma, showing unexpected relationship between these two areas, separated by 280 km. Within the Pamphagus djelfensis complex, a new species is described,P. batnensis Benkenana& Petit, easily distinguishable by its epiphallic characters. Taking into account severalstudies dealing with other Algerian stations, we provide certain climatic constraints of most species, as illustrated by bioclimagrams. We show that the semi-arid stage with fresh winter and sub-humid stage with cold winter correspond to the most suitable conditions for this family.
We studied the diet of 10 species of grasshoppers belonging to the family Pamphagidae. The examination of plant epidermis in faeces allowed to determine all the plant species consumed, by comparison with a bank of epidermis constructed from field samples. All the grasshopper species were revealed to be polyphagous, but the percentages of consumed Poaceae are variable among species. Tmethisand Ocneridiafeed on Poaceae at a higher rate than other species and are considered as ambivores. In Pamphagusgr. djelfensis, the three species rather avoid Poaceae and are qualified as forbivore. Their diet cannot be distinguished between each other. We also compared the frequency of Fabaceae in the faeces to their abundance in the field, and O. volxemiiis the only species avoiding this plant family.
The sensilla repertoire in the labrum was also studied in both sexes of each species. Once the size effect of labrum is removed, we found that forbivore species harbour higher numbers of sensilla of type A1, A2, and A3 (but not A10) than ambivore species. This last category is more abundant in Pamphagidae than in Acrididae where graminivore diet is prevalent, suggesting a food mode adapted to semi-arid conditions.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/BEN6356.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=6356 Inventaire et analyse bio systématique de la famille des Pamphagidae (Orthoptera, Caelifera) de l’Est algérien [texte imprimé] / Naima Benkenana, Auteur ; Aboud Harrat, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2013 . - 136 f. ; 30 cm.

The symbiosis Rhizobium-legume leads to the formation of root nodules fixing atmospheric nitrogen. This natural process has a considerable economic and agronomic interest. In Algeria, the production of food and forage legume is affected by environmental and climatic stresses (high temperature, water deficit...). In this study, total of 237 isolates were isolated from root nodules collected on lentil (Lens culinaris), proteaginous and forage peas (Pisum sativum) grown in the field in six sites representing two contrasting eco-climatic zones, sub humid and semi-arid in Eastern Algeria. The main objective was to determine the
degree of variability of the genetic structure of populations of Rhizobium nodulating among sites and isolated plants in different climatic conditions. Our isolates were characterized by PCR-restriction fragment length polymorphism (RFLP) of the 16S-23S rRNA intergenic region (IGS), and the nodD-F symbiotic region. The combination of these haplotypes allowed to clustered the isolates into 26 distinct genotypes. Phylogenetic analysis of 16S rDNA sequences allowed us to classify all isolates as Rhizobium leguminosarum. Results obtained showed that the variation of symbiotic marker (nodD-F) is low with the predominance of one
haplotype nod g, previously recovered at high frequency in Europe. Sequence analysis of IGS further confirmed its high variability in the studied strains. An AMOVA analysis showed highly significant differentiation in the IGS haplotype distribution between populations from both eco-climatic zones. This difference was reflected by differences in dominant genotype frequencies. Conversely we could not detect any host plant effect. The nodD gene sequence based phylogeny suggests that symbiotic gene diversity in pea and lentil nodulating rhizobial populations in Algeria is low compared to that reported elsewhere in the world.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/RIA6607.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9720 Diversité et structure génétique des populations de Rhizobium leguminosarum symbiovar viciae isolées du pois (Pisum sativum) et de la lentille (Lens culinaris) cultivés dans deux zones éco-climatiques subhumide et semi-aride de l'est Algérien [texte imprimé] / Nassira Riah, Auteur ; Abdelhamid Djekoun, Directeur de thèse ; Gisèle Laguerre, Directeur de thèse ; Philippe De Lajudie, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2014 . - 131 f. ; 30 cm.

?????? ?????? ???????/????? ?????? ???????Index. décimale : 570 Sciences de la vie. Biologie Résumé : The use of data on the health status of populations throughout the world, and their importance in the development of protocols and strategies for care and prevention are currently the subject of great interest. In Algeria, the increasing prevalence of overweight and obesity continues significantly. It is the consequence of a radical change in the mode
of life.
A cross-sectional survey of 273 households from 12 districts located in urban areas in 1091 and introducing people, aged 18-75 years, helped describe the epidemiological profile and enjoy the oxidant / antioxidant status of the population overweight in the town of Ain Fakroun located in eastern Algeria.
The epidemiological approach shows that over one third (1/3) of the recruited population is overweight (BMI> 25 kg / m²). The prevalence increased significantly (p = 0.0014) in adult women and then gradually decreases with age and drops significantly among seniors over 60 years. The study of the association between BMI levels and risk factors reinforces conventional notions. From a descriptive point of view, among both men and women, overweight seems strongly linked to social, biological and environmental factors.
The evaluation of various parameters related to oxidative / antioxidant status indicates an imbalance in the obese. The imbalance seems more pronounced among women. A negative relationship was observed between adiposity and antioxidant capacity for the presence of oxidative stress in obese individuals from our study sample. Indeed, we found reduced levels of antioxidant systems, proved through in reduced plasma levels of vitamin E and vitamin A, glutathione, trace elements linked to the system in this case zinc, even where enzymes, particularly the CAT. Added to the significant concomitant increase in the levels of oxidizing system including lipid peroxidation and copper in the blood plasma of obese compared to overweight individuals.
With the advent of industrialization, bank loans and medical care, the situation remains a concern in our country since the trend is for a development that alarmed plagues. Also, a prevention strategy is urgent to undertake.
