Environmental data for: Brine contamination gradients drive taxonomic turnover and niche specialization of soil microbial communities

This dataset supports an environmental study focusing on the effects of brine contamination on soil microbiota within a 25-hectare site impacted by brine in Northern Alberta, Canada. Soil samples were collected along four transects, each extending 300 meters, to cover a gradient from unaffected to severely affected by brine, incorporating analyses of both the A and B soil horizons. The investigation included a microbiome analysis leveraging 16S rRNA amplicon sequencing, enabling the examination of microbial community structure and diversity. Included within this dataset are alpha diversity indices (Faith's Phylogenetic Diversity and Shannon Entropy) and beta diversity assessments (Weighted UniFrac distance Principal Coordinates Analysis).

本数据集支撑一项针对加拿大阿尔伯塔省北部25公顷受盐水污染场地的环境研究，聚焦盐水污染对该场地土壤微生物群的影响。研究沿四条各延伸300米的样带采集土壤样本，以覆盖从未受污染至严重受盐水污染的污染梯度，并纳入了土壤A层与B层的相关分析。本次调查采用16S rRNA扩增子测序技术开展微生物组分析，得以解析微生物群落的结构与多样性。本数据集包含α多样性指数（Faith's 系统发育多样性与香农熵）以及基于加权UniFrac距离的主坐标分析的β多样性评估结果。
