Research ArticleOpen accessIn the keywordsMonitoring of the Saiga Population: Balancing Nature and AgricultureZhanbolat Ibraibekov, Saule Atshabarova, Ermek Gabdullin et al.The rapid recovery of the Saiga population (Saiga tatarica) in Kazakhstan represents a significant conservation success; however, it has simultaneously generated complex ecological and socio-economic challenges in steppe ecosystems. This study evaluates the relationships between Saiga population density and pasture ecosystem condition and identifies ecological thresholds relevant to balancing biodiversity conservation and sustainable agricultural land use. The research is based … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 27 Oct 2026 · 50 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimisation of Plant Mineral Nutrition, Growth Stimulation and Yield Enhancement Through the Use of a Bio Formulation Based on Phosphate Solubilising BacteriaZhanar Zhumadilova, Laura Tokhetova, Gulsim Baimbetova et al.The aim of this study was to evaluate the agronomic and fodder efficiency of various fertilisation treatments in relation to their effects on plant growth, chemical composition, and soil properties. The study evaluated the effectiveness of a bio-formulation based on Phosphate-Solubilising Bacteria (PSB) in combination with mineral fertiliser (N60P90 + N30) in enhancing the productivity of forage crops and improving … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 23 Sep 2026 · 392 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRotational Pasture Management for Ameliorating Productivity and Feed Value of Vegetation, Soil Quality, and Sustainability in Dry Steppe ZoneGani Stybayev, Meisam Zargar, Beibit Nasiyev et al.Over the past years, a farming system in the Akmola region of Kazakhstan has undergone significant changes: The average number of animals per farm and the use of external inputs have significantly enhanced while the diversity of farming practices has decreased, becoming similar to intensive farming. In this research, we evaluated the rotational pastures for increasing the productivity and feed … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 18 Jan 2025 · 4,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPoly-Species Phytocenoses for Ecosystem Restoration of Degraded Soil CoversAlmabek B. Nugmanov, Sergey V. Mamikhin, Khusain Kh. Valiev et al.Agroecological studies are based on the concept that, by understanding ecological processes, it is possible to manage agroecosystems for more sustainable production of more biomass and, thus, protection of natural resources. Many studies in the field of agroecology show that some farming methods can improve soil quality and restore agroecosystems by increasing plant biodiversity. Functional characteristics of plants for the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 22 Jul 2022 · 5,716 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDNA Yields and PCR Amplification Success Using Degraded Animal CorpsesJimmy Ilunga, Paul Michael, Grace Daniel et al.A recurring problem with ancient specimens from wildlife animals is that their preserved tissues contain small amounts of DNA in a degraded state. The specific objectives of the present study were: (1) To determine DNA yields from different animal tissues; (2) to compare traditional (manual) DNA extraction protocols with commercial procedures and (3) to assess the success of PCR amplification … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 12 Feb 2020 · 7,483 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSELECTIVE ISOLATION OF A GRAM NEGATIVE CARBAMATE PESTICIDE DEGRADING BACTERIUM FROM BRINJAL CULTIVATED SOILDilara Islam Sharif, Mithun MollickA bacterial species having the ability to grow in the presence of carbosulfan pesticide “Marshall” was isolated from Solanum melongena (brinjal) cultivated soil in Khulna region, Bangladeh, having a history of pesticide usage. The strain was morphologically and biochemically identified to belong to the genera Pseudomonas. A comparative study of growth of this strain with other isolated bacteria showed its … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 24 Sep 2013 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalytic and Nonlinear Prognostic for Vehicle Suspension SystemsAbdo Abou Jaoude, Khaled El-TawilPredicting Remaining Useful Lifetime (RUL) of industrial systems becomes currently an important aim for industrialists knowing that the expensive failure can occur suddenly. As the classical strategies of maintenance are not efficient and practical because they neglect the evolving product state and environment, the recent prognostic approaches try to fill this gap. This approach shows to be important in ensuring … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 23 Feb 2013 · 7,526 accessesView PDFCite
