Research ArticleOpen accessIn the abstractVegetation Analysis of Sutan-Chay Basin in ArasbaranT. Ebrahimi Gajoti, V. Haciyev, A. Javanshir et al.Problem statement: Plants associations differ in relation to environmental gradients. Therefore, it is necessary to study the interaction between ecological factors and vegetation. Approach: In this study vegetation and flora of Sutan-Chay Basin in Arasbaran was investigated using Braun Blanquet method as physiognomic floristic. Sampling of soil and vegetation was carried out by selecting areas with homogenous plant compositions. The … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,879 accessesView PDF Cite

InvestigationOpen accessAll words, across the recordChanges in the Composition and Properties of Meadow Solonchaks of the Ili Alatau Foothill Plain in the Republic of Kazakhstan during a Long Postmeliorative PeriodZhainagul Yertayeva, Saginbay Kaldybaev, Aigul Kaiyrbekovna BeketovaThe optimal depth of the groundwater table and the water-salt regime is of importance in the postmeliorative period. The scope of these studies is to provide scientifically grounded assessment of previously reclaimed soils (water irrigation with a total norm of 5000 m3/ha under conditions of deep horizontal drainage, 1986-1989) in the postmeliorative period of 2015-2016 and to develop parameters for … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Oct 2017 · 7,265 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordElemental Composition and Concentration of Atmospheric Particulate Matter in KuwaitJasem M. Al-Awadhi, Anwar B. Al-HelalHourly PM10 and PM2.5 samples were simultaneously collected at 10 and 3 urban sites, respectively in Kuwait from March 2014 to February 2015, to study the air quality and heavy metals content and Total Petroleum Hydrocarbons (TPHs) in PM10 samples. The annual average concentrations of PM10 and PM2.5 were 152 and 97.3 μg/m3, respectively, with an average PM2.5/PM10 ratio of … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 18 Feb 2017 · 7,623 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Impact of Chernozem Contamination with Lead and Oil on the Abundance and Composition of MicroarthropodsSergey Ilyich Kolesnikov, Lidiya Sergeevna Samokhvalova, Maria Gennadievna Zharkova et al.Micro arthropods population reduced with increase in the amount of oil in chernozem. The same pattern was observed up to a certain concentration of lead in the soil (background + 250 mg kg-1) and then at high doses (+500 and +1000 mg kg-1) an increase in microarthropods abundance was recorded. Gamazid mites and acaroid-trombidi form complex mites proved to be … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 29 Apr 2015 · 7,598 accessesView PDF Cite
