Quantitative relationships between soil N availability indices and tree growth are lacking in the oil sands region of Alberta and this can hinder the development of guidelines for the reclamation of the disturbed landscape after oil sands extraction. The aim of this paper was to establish quantitative relationships between soil N availability indices and(More)
In Table 3 of the original version of this article incorrect units were unfortunately inadvertently introduced during the revision stage. The correct units should be mg NH 2 –N kg −1 soil h −1 for protease and mg p-nitrophenol kg −1 soil h −1 for acid phosphatase, alkaline phosphatase and total phosphatase.
Understanding changes in soil N cycling with stand development is critical for forest management as tree growth is affected by soil N availability. The aim of this study was to evaluate the changes in soil N availability and loss with stand development in trembling aspen (Populus tremuloides Michx.) and jack pine (Pinus banksiana Lamb.) in northeastern(More)
Water and energy processes in frozen soils are important for better understanding hydrologic processes and water resources management in cold regions. To investigate the water and energy balance in seasonally frozen soils, CoupModel combined with the generalized likelihood uncertainty estimation (GLUE) method was used. Simulation work on water and heat(More)
The study investigated the effects of different CaCl2 concentrations (2, 5, and 10 mM) on photosynthetic enzymatic activities, photosynthesis, and chlorophyll fluorescence of tung tree seedlings under drought conditions. Plants were sprayed with either CaCl2 or distilled water until run-off. Irrigation was then withheld to induce drought stress. The(More)
Glutathione (GSH) plays an important role in maintaining redox homeostasis inside cells. Currently, there are no methods available to quantitatively assess the GSH concentration in live cells. Live cell fluorescence imaging revolutionized the field of cell biology and has become an indispensable tool in current biological studies. In order to minimize the(More)
Ornamental value of 20 Rhododendron species were investigated A total of 13 ornamental characteristics were evaluated using Fuzzy Similarity Priority Ratio and Grey system method in the "One Hundred Li Rhododendron" Forest Area in Guizhou, China. This result indicated that ten species with higher ornamental value should be widely cultivated in this Forest(More)
