Functional analyses of nanoparticle toxicity: a comparative study of the effects of TiO2 and Ag on tomatoes (Lycopersicon esculentum).
Methods to test the phytotoxicity of two distinctly different NPs, one aerosol (nano-TiO2) and the other colloidal silver (AgNP), by specifically considering their tendencies to agglomerate and form precipitates are developed. Expand
Investigation of heavy metal accumulation in Polygonum thunbergii for phytoextraction.
Results from this study considered these results as indicative of the ability of P. thunbergii plants to take up metal ions from a soil matrix contaminated with heavy metals. Expand
Functional Analysis of TiO2 Nanoparticle Toxicity in Three Plant Species
It is suggested that titanium itself is not phytotoxic, even though plants absorb titanium, and nano-TiO2 is not toxic to the three plant species, in vitro or in situ. Expand
Management of pine wilt disease in Korea through preventative silvicultural control
Abstract Pine wilt disease (PWD) represents a major threat to forest ecosystems worldwide. Although PWD is now better understood, effective control measures for this disease have still not beenExpand
Comparison of UV-VIS and FDOM sensors for in situ monitoring of stream DOC concentrations
Abstract. Optical measurements using ultraviolet–visible (UV–VIS) spectrophotometric sensors and fluorescent dissolved organic matter (FDOM) sensors have recently been used as proxies of dissolvedExpand
Atmospheric deposition of macronutrients by pollen in the boreal forest
The combination of highly episodic, early summer deposition and very rapid nutrient turnover suggest that pollen may play an important role in supplying nutrients and promoting decomposition in the forest litter layer. Expand
Macronutrient input from pollen in two regenerating pine stands in southeast Korea
Although the annual contribution of nutrient mass by pollen is small compared to that of litterfall, the rapid turnover rate of pollen nutrients combined with episodic deposition suggests that pollen may play a disproportionate role in temperate pine forest nutrient cycling. Expand
Comparison of phenolic compounds and the effects of invasive and native species in East Asia: support for the novel weapons hypothesis
One prediction of the novel weapons hypothesis (NWH) for the dominance of exotic invasive plant species is that the allelopathic effects of successful invaders will, in general, be more biochemicallyExpand
Soil seed bank of the waste landfills in South Korea
The restoration of urban landfill is a topic of growing interest in reclamation ecology as the acreage of abandoned sites near cities increases. The goals of this study were to assess the ecologicalExpand
Ecological application of biotic resistance to control the invasion of an invasive plant, Ageratina altissima
Functional group identity and diversity of resident plant communities were good indicators of biotic resistance to invasion by introduced A. altissima, with the underlying mechanisms likely niche pre‐emption and niche partitioning. Expand
