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.

北方森林中植物的生长期很短。因此，对于植物如何以及何时获取氮非常重要，氮是其生长的限制因素。本研究从氮源和季节性的角度对植物氮素利用进行了研究。我关注的是森林火灾或河流洪水等森林干扰后出现的早期演替物种。结果显示出主要的物种差异，这表明对氮的竞争受到源分离或时间分化的抑制。
