Research ArticleOpen accessPhrase in the titleSummarizing Spatial Distribution Density, Movement Patterns and Food Resources to Study the Impacts of Logging and Forest Conversion on Orang-utan PopulationRaymond Alfred, Koh Pei Hue, Lee Shan Khee, Rayner AlfredProblem statement: Orang-utan is classified as a totally protected species and is listed as an endangered species in Borneo. The survival of this species is highly dependent on the existence and quality of the lowland forest of Sabah. However, most of the pristine habitats in the lowland area have been converted into other land use activities such as a large … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 31 Oct 2010 · 8,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Converting Tropical Peat Swamp Forest into Oil Palm Plantation on Water QualitySeca Gandaseca, Noraini Rosli, Mohd Hanafi Idris et al.Peat swamp forest is a unique forest and wetlands ecosystem that recognized as one of the most important reservoir of biodiversity and water resources protection. Rapid development particularly for development, agriculture and plantation in peat swamp forest (PSF) area had given negative impacts to its ecosystem included degradation of its water quality. This study was conducted to determine water quality … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 3 Sep 2015 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractLAND USE LAND COVER DYNAMICS OF NILGIRIS DISTRICT, INDIA INFERRED FROM SATELLITE IMAGERIESP. Nalina, T. Meenambal, R. Sathyanarayan SridharLand use Land cover changes are critical components in managing natural resources especially in hilly region as they trigger the erosion of soil and thus making the zone highly vulnerable to landslides. The Nilgiris district of Tamilnadu state in India is the first biosphere in Western Ghats region with rare species of flora and fauna and often suffered by frequent … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 13 Jan 2014 · 7,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Soil Microbial Population, Enzymatic Activity and Biomass of Selected Natural, Secondary and Rehabilitated ForestsK. S. Daljit Singh, A. Arifin, O. Radziah et al.Substantial clearance of forests and conversion of forest into various land use types contribute to deterioration of soil fertility and associated nutrients loss. Soils from natural and rehabilitated forest in Chikus Forest Reserve and also enrichment planting forest and secondary forest of Tapah Hill Forest Reserve, Perak, Malaysia were selected in order to assess the influence of land use change … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,807 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand Degradation and Preventive Measures From the Perspective of the StakeholdersMosayeb Heshmati, Arifin Abdu, Nik Muhamad Majid, J. ShamshuddinLand degradation at the catchment scale in Iran is widespread, usually assumed to be accelerated by the activities of local inhabitants. Social issues such as low income, poverty and low level of welfare and education contribute to land degradation. A study was conducted to identify the causes of land degradation in Merek catchment, Iran and to propose appropriate measures to … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 8,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Soil Fertility Status of Rehabilitated Degraded Tropical RainforestAiza Shaliha Jamaluddin, Arifin Abdu, Hazandy Abdul-Hamid et al.An assessment of forest rehabilitation program in relation to soil fertility status by using soil indices could provide fundamental information on soil suitability for species preferences and improve the effective technique for future rehabilitation program in tropical rainforests. This study was conducted in order to characterize the soil properties and identifying the soil fertility status of rehabilitated and secondary forests. … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 8,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Land Use Practices on the Organic Carbon Content, Cation Exchange Capacity and Aggregate Stability of Soils in the Catchment ZonesMosayeb Heshmati, Arifin Abdu, Shamshuddin Jusop, Nik Muhammad MajidProblem statement: Land use practice leads to changes in the physico-chemical properties of soils, such as Soil Organic Carbon (SOC), Cation Exchange Capacity (CEC) and Soil Aggregate Stability (SAS) that cause soil erosion. Approach: Merek catchment, Iran suffers from land degradation due to poor land use practice. A study was carried out with the objectives: (i) to determine soil nutrient … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 25 Oct 2011 · 8,726 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Fertility of Soils under Khaya ivorensis Plantation and Regenerated Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem statement: It is widely accepted that conversion of natural forest to other land use types leads to deterioration of soil fertility and increased soil compaction which consequently become degraded secondary forests. Degraded secondary forest or forestland is indicated by low in soil fertility and organic matter due to imbalance input and output from original vegetation. Forest plantation through planting … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Converting Secondary Tropical Peat Swamp Forest into Oil Palm Plantation on Selected Peat Soil Physical PropertiesMohd Suffian Firdaus, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: The conversion of forest land into oil palm plantation is considered to be one of the causes of soil degradation and loss of tropical land forest in Southeast Asia. The objective of this study was to compare selected peat soil physical properties of secondary tropical peat swamp forest and oil palm plantation to determine the effect of forest … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,749 accessesView PDFCite
