Effects of permafrost thaw on nitrogen availability and plant-soil interactions in a boreal Alaskan lowland: IV - Plant vs Nitrogen Data 2013

This dataset examines shifts in soil and plant characteristics, and extractable soil pore water chemistry along a lowland boreal permafrost thaw chronosequence. Data was collected in 2013 at the APEX Beta and forested study plots, located adjacent to the BNZ experimental forest. Data includes mean DIN, DON, free amino acids, and TDN from seasonal pore water measurements as well as aboveground vegetation C and N concentrations, and summertime, litterfall % N, and resorption efficiency for C. calyculata.

本数据集旨在分析低地北方冻土解冻时间序列样带上的土壤与植物特性，以及可提取土壤孔隙水化学性质的动态变化。相关数据于2013年在毗邻BNZ实验林的APEX Beta样地与森林研究样地中采集得到。数据集涵盖基于季节性孔隙水测定获得的溶解态无机氮（Dissolved Inorganic Nitrogen, DIN）、溶解态有机氮（Dissolved Organic Nitrogen, DON）、游离氨基酸与总溶解氮（Total Dissolved Nitrogen, TDN）的均值，同时包含地上植被碳（C）、氮（N）浓度、夏季凋落物氮含量百分比，以及C. calyculata的养分重吸收效率。
