For the first time, a complex of insect pests and entomophages is being specified in the Astana green belt stands. The biological effectiveness of biopreparations and insecticides against harmful insects in the system of protective measures and the forest … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 18 Jan 2018 · 7,520 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleComparison of Microbial and Heavy Metal Contents in Soils and Roots under Mangrove Forest Stands with Different Levels of Pollution in the Niger River Delta, NigeriaAroloye Ofo NumbereOil and gas exploration in the Niger Delta, has resulted to increased heavy metal contamination. It is thus postulated that increased heavy metal will lead to decreased microbial content in soil and root. To test this hypothesis ten replicates each of soil and root samples were collected from already established sites. Samples were sent to the laboratory for analyses of … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 25 Jun 2017 · 8,177 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHydrophysical 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 · 1,316 accessesView PDFCite
Research ArticleOpen accessIn the abstractFormation of Post-Fire Water Repellent Layers on Nothofagus glauca (Hualo) Forests, After the Historical “Las Máquinas” Wildfire in South-Central ChilePablo A. Garcia-Chevesich, Eduardo Martínez, Alejandro García et al.The Chilean summer of 2017 was the worst wildfire season by far. Hundreds of wildfires burned a total of more than half a million hectares of forested land (native forests and forest plantations). A significant portion of the burned area was occupied by Hualo (Nothofagus glauca (Phil.) Krasser), a native forest species widely distributed in central Chile. Using the water-drop-penetration-time … …American Journal of Environmental Sciences, Vol. 15, Issue 1 · 15 Jan 2019 · 9,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvivorship and Growth Performance of Shorea macrophylla (de Vriese) after Enrichment Planting for Reforestation Purpose at Sarawak, MalaysiaMugunthan Perumal, Mohd Effendi Wasli, Ho Soo Ying et al.Reforestation may offer one means of mitigating the processes of forest land degradation and is indispensable in an effort to conserve forest biological diversity in the tropics. Thus, a preliminary assessment was conducted in order to evaluate the survivorship and growth performance of Shorea macrophylla (de Vriese) after enrichment planting for reforestation purpose in Sarawak, Malaysia.
