| Research Abstract |
The growth period for plants is short in boreal forests. Therefore, it is important for plants how and when they acquire nitrogen, which is the limiting factor for their growth. In this study, plant nitrogen use was investigated from the viewpoint of nitrogen source and seasonality. I focused on the early successional species that appeared after forest disturbance such as forest fire or river flooding. The results showed major species differences, which suggested the competition for nitrogen was restrained by separation of source or temporal differentiation.
