Soil metagenome Raw sequence reads

In this study, we address questions about the effects of biogeochemistry and seasonal variation during vertebrate decomposition. The goal of this study was to integrate soil biogeochemistry with microbial changes during human decomposition. In a field study conducted at the University of Tennessee Anthropology Research Facility, soils were collected at two depths, 0-1 cm (interface), and 1-16 cm (core), from controls and from underneath three decomposing human individuals for the period of one year, beginning in the winter. Soil physicochemical parameters were measured, and microbial (bacterial and fungal) communities were assessed via 16S and ITS amplicon sequencing. This dataset is compared to a secondary dataset beginning in the spring.

本研究聚焦脊椎动物腐败过程中的生物地球化学效应与季节变化相关问题。本研究的核心目标为，将土壤生物地球化学特征与人类腐败过程中的微生物群落变化进行整合分析。本研究于田纳西大学人类学研究设施（University of Tennessee Anthropology Research Facility）开展野外实验：以冬季为起始节点，在为期一年的周期内，分别从对照组与3具正在腐败的人类遗体下方采集土壤样本，采样深度分为两层——0~1 cm（界面层）与1~16 cm（核心层）。研究人员对土壤理化参数进行了测定，并通过16S与ITS扩增子测序技术对细菌与真菌群落开展评估。本数据集将与另一组始于春季的辅助数据集进行对比分析。
