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.

CD ?????????? ? ????? 36Index. décimale : 570 Sciences de la vie. Biologie Résumé : This study aims at determining the incidence of overweight and obesity in children aged, from 7 to 8 years, attending school in the town of Constantine, with a follow-up for three years 2009-2010, 2011-2012 and 2012-2013.
The determinants of obesity are multiple and complex interactions. Beyond the individual biological or genetic factors that can not be ignored, obesity is primarily the result of an energy imbalance but this imbalance is strongly influenced by the child's environment, as well as early throughout the life.
We have also characterized in a second part of the risk factors associated with overweight. The third objective of this thesis was to investigate a relationship between fat taste and weight. Whether the oral sensitivity, in the obese, to oleic acid and normal weight children was the same. In other words, if they had the same fat taste detection thresholds or if this threshold was altered in obese children. There was a significant correlation between
age and childhood obesity.
The low level of education, corpulence of the parents, macrosomia seem to play an important role in the development of childhood obesity. Although the difference was not significant, obesity is more common in children with artificial feeding. Obese children are more sedentary compared to normal weight.
Obese children took less often breakfast compared to normal weight ones. They also tended to take more snacks in the evening and throughout the day with high energy density foods. All children consumed foods high in fat, grains, starches, meats and fish and soft drinks during lunch and dinner.
Obese children appear to have a significant reduction (40 times) in the gustatory perception of fat taste. These differences in taste sensitivity may be the result of polymorphism of CD36 gene. Early preventive actions, therefore, are necessary to stop and, if possible, reverse the progression of overweight/obesity.
