Temporal transect of moss-associated N2 fixation rates in Anchorage, Fairbanks, and Toolik

This is a dataset coving multiple moss species (Hylocomium splendens, Ptilium crista-castrensis, Pleurozium schreberi, Sphagnum sp., others) and their associated d15N following incubation with 15N2 in June, July, and August over the course of one growing season in 2017. Three sites at each location (Anchorage, Fairbanks, and Toolik Field Station) were sampled. We measured rates of nitrogen fixation using 15N2 incubations in a common garden close to the sites of collection.

这是一个涵盖多种苔藓物种（Hylocomium splendens、Ptilium crista-castrensis、Pleurozium schreberi、Sphagnum sp.及其他）及其在2017年一个生长季的6月、7月和8月期间经15N2培养后的相关d15N数据的数据集。在每个地点（安克雷奇、费尔班克斯和Toolik野外站）选取了3个采样点。我们在靠近采集地点的同质园中，采用15N2培养法测定了固氮速率。
