New and regenerated sources of nitrogen: from the ice edge to the equator in ...

The distribution of diazotrophs and the magnitude of N2 fixation along with the input of new N through this process remains poorly constrained globally, but particularly in the...全球范围内，固氮微生物（diazotrophs）的分布、固氮作用（N2 fixation）的强度，以及该过程所输入的新增氮素，相关研究与数据约束仍较为不足，而在……方面这一情况尤为显著。
