| changes in the grassland-forest boundary at ta-ta-chia long term ecological research (lter) site detected by stable isotope ratios of soil organic matter. | the carbon isotope analysis [delta13c values] of organic samples can be a useful research in ecological studies because delta13c values are indicative of the plant source. this study investigated the changes in plant communities along the grassland-forest boundary in the alpine forest at ta-ta-chia long term ecological research (lter) site in central taiwan using carbon isotope data. the aim of this study was focused on the forest fire affected the change of vegetation community. four pedons fro ... | 2004 | 14559272 |
| humic substances affect the activity of chlorophyllase. | three humic substances--humic acid, fulvic acid, and humin--were isolated from soils located in the northern and southern forests of the yuanyang lake nature preserve in northern taiwan's ilan county. aqueous extracts of fresh wet soil and of three humic substances, at concentrations of 0.125, 0.25, and 0.5 mg/ml, were investigated for their effects on the activities of chlorophyllase a and b. aqueous extracts of forest soils at the northern and southern bank, dominated by the pure vegetation of ... | 2004 | 15274448 |
