Abstract:
... The white-rot fungi Phanerochaete chrysosporium have been widely applied in heavy metal bioremediation, which commonly results in a stress exposure. Exposure studies showed that Cd bioaccumulation triggered H2O2 generation. Thereafter, the H2O2, as signal molecules, activated the enzymatic antioxidant response in the case of the conjunction of SOD and CAT. High levels of R (SOD/CAT) were found ini ...

Abstract:
... Peat-mineral soil mix (PMM) over tailings sand (TS) or overburden (OB) is a commonly used prescription for oil sands reclamation. The TS and OB (the substrates) often have unfavorable conditions such as high salinity, soil compaction, low nutrient availability in OB, and low nutrient and water availabilities in TS, which may limit tree growth. The objective of this study was to identify limiting f ...

Abstract:
... The geographic patterns of leaf nutrients in different ecosystems have drawn great attention from stoichiometric ecologists. Two hypotheses, temperature–plant physiological hypothesis (TPPH) and temperature–biogeochemical hypothesis (TBH), were proposed to explain the effects of temperature on terrestrial plants nutrients concentrations and stoichiometry. However, the patterns and causes of variat ...
