In recent years, due to the increased population, urbanization and changes in human consumption patterns, urban, industrial and agricultural soils have been exposed to various pollutants such as heavy metals. The objective of this research was to identify hotspots of Pb by using global and local Moran Indices in urban and suburban soils of Kashafrood catchment. A total of 261 surface soil sampl...
Tropical and subtropical freshwater habitats are among the most biodiverse ecosystems worldwide, containing a characteristic fauna high numbers of endemic species. However, exploitation organisms, global climate change, pollution introduction invasive species severely threatening this diversity. Implementation appropriate conservation protection measures in tropical systems depends on comprehen...
Subtropical and tropical forests are biodiversity hotspots, and untangling the spatial scaling of their diversity is fundamental for understanding global species richness and conserving biodiversity essential to human well-being. However, scale-dependent diversity distributions among coexisting taxa remain poorly understood for heterogeneous environments in biodiverse regions. We show that dive...
This paper examines the environmental impacts of climbing ropes using life cycle assessment (LCA). An online survey was conducted to evaluate users’ behaviour and potential an open loop recycling project for old ropes. The results LCA study show that production base material, polyamide 6, has, at 50%, highest impact on total global warming 46.6 kg CO2-eq. per rope most other issues. At present,...
Despite heated debates over the safety of genetically modified (GM) food, GM crops have been expanding rapidly. Much research has focused on the expansion of GM crops. However, the spatiotemporal dynamics of non-genetically modified (non-GM) crops are not clear, although they may have significant environmental and agronomic impacts and important policy implications. To understand the dynamics o...
In a continuing effort to develop inexpensive source tracking methods to detect human fecal contamination in environmental waters, we combined targeted sampling with fluorometry. Targeted sampling works by identifying hotspots of fecal contamination through multiple samplings over everdecreasing distances. Fluorometry identifies human fecal contamination by detecting optical brighteners, primar...
