Research ArticleOpen accessEvery word in the titleASSESSING SOIL RESPIRATION AS AN INDICATOR OF SOIL MICROBIAL ACTIVITY IN RECLAIMED METAL CONTAMINATED LANDSKassandre Goupil, Kabwe NkongoloMining, roasting as well as smelting of these elements have caused sulphur dioxide fumigations and metal particulate depositions which have led to various detrimental effects on the overall environmental quality of the Greater Sudbury region. Soil amendment and revegetation within the Greater Sudbury Region were initiated to restore the damage land. Several methods have been used to assess the progress … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 11 Jul 2014 · 8,104 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhytoplankton Diversity as Indicator of Water Quality for Fish CultivationArunava Pradhan, Pranami Bhaumik, Sumana Das et al.Waste water fed fisheries are a common feature in different parts of the world. Yet not all work as efficiently as those operating at East Calcutta Wetland for more than 70 years now. The objective of this study is to unravel the reason for the markedly greater efficiency of the Bheris in fish production compared to other water bodies like … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,655 accessesView PDFCite

This paper presents data on the morphometric characteristics of rainbow trout fry grown in three types of farms in Kazakhstan and wild forms from Lake Lower Kolsay. The comparison was … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 1 Apr 2026 · 1,391 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHydrophysical Properties of Soils as Indicators of the Hydrological Role of Rudny Altai ForestsAndrey Kalachev, Tamara Burenina, Stanislav Rogovsky et al.The hydrophysical properties of soils and parent rock are key factors shaping forest hydrological functioning, as they influence multiple runoff components. This study assessed the effects of forest stand composition on soil moisture and water permeability between 2021 and 2023 in the middle mountain-taiga zone of the Rudny Altai, within the Zhuravlikha River basin, a tributary of the Irtysh River. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 24 Mar 2026 · 1,322 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePod Shattering and Seed Shedding Resistance Indicators in the Soybean Collection and Hybrid PopulationsSagit Islambek, Didorenko Svetlana, Rinat Kasenov et al.Early pod shatter is a critical factor contributing to soybean yield loss, with potential losses ranging from 34 to 99%. When shatter-resistant genotypes are grown in different agro-climatic zones, there is often a loss of this resistance. Therefore, there is a need for a more detailed critical analysis of breeding methods and strategies to reduce soybean pod shatter. It has … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 25 Nov 2025 · 2,027 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Quantitative Analysis of Preparedness and Performance: Predictive Indicators in First-Year Tertiary MathematicsGurudeo Anand TularamStudent preparedness at university entry plays a critical role in determining success in mathematics courses. This study investigates how three observable behaviours: (1) completion of weekly problem sets, (2) regular tutorial attendance, and (3) performance on a mid-semester test. We investigate how they relate to each other and their final examination results. Over five years, data were collected from 450 … …Journal of Social Sciences, Vol. 21, Issue 1 · 10 Oct 2025 · 2,728 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFormation of Vegetation Cover and Soil Quality Indicators at the Mine Sites of a Gold-Bearing Deposit (the Case of Kara-Agash, Kazakhstan)Vadim Chashkov, Aliya Bugubaeva et al.At present, the processes of natural recovery, vegetation coverage, and degraded lands of several coal, iron ore, uranium, and polymetallic mines and gold-bearing deposits are well-studied. The present study aims to identify opportunities to shape the soil layer and vegetation cover on reclaimed dumps/tailings of industrial waste and degraded land via artificial restoration. For this purpose, in July 2023, studies … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 16 Sep 2024 · 4,773 accessesView PDFCite
