Mean values of important co-variates at the full range of distance classes from the DMTS haul road in CAKR, with the standard error of the mean (presented in parentheses).

Mean elemental values are mg/kg in Hylocomium splendens tissue, dry weight, except % Total S and % Total N. Values are presented for the Reference Sites and the Kotzebue road sites that were not included in subsequent analyses of vegetation community structure. The 2001 values for Cd, Pb and Zn are from Hasselbach et al. [18].

本数据集的元素平均含量以干重计的塔藓（Hylocomium splendens）组织中的毫克每千克（mg/kg）为单位，总硫（% Total S）与总氮（% Total N）除外，二者以百分比形式表征。本次发布的含量数据涵盖参照样地（Reference Sites）与未被纳入后续植物群落结构分析的科策布公路样地（Kotzebue road sites）。2001年的镉（Cd）、铅（Pb）与锌（Zn）含量数据引自Hasselbach等人[18]的研究。
