Microbial Ecology of Antarctic Soils

Metadata record for data from ASAC Project 36See the link below for public details on this project.From the abstract of one of the referenced papers - &Environmental conditions and microbiological properties from soils and lichens from Antarctica (Casey Station, Wilkes Land)&:Microbial habitats of an Antarctic coastal terrestrial environment are described. Emphasis was laid on soil with different contents of organic matter and some representative lichen species. Parameters for this description were microclimatic conditions, organic and inorganic matter, epifluorescence microscopy, and parameters describing microbial and enzymatic activity. The data of direct measurements of bacterial standing stock (number and biomass) and of exoenzymatic activity via FDA-hydrolysis were found to be the most valuable parameters for microbiological properties. The data show significant differences with regard to nutrients and microbial activity. Scales of patches are only a few square decimetres with wide ranges of environmental and microbiological properties within short distances.

本数据集的元数据记录来源于ASAC 36项目（ASAC Project 36），该项目的公开详情可通过下方链接查阅。本文引自其中一篇引用论文的摘要——《南极洲威尔克斯地凯西站土壤与地衣的环境条件及微生物学特性》：本研究对南极沿海陆地环境的微生物栖息生境展开描述，重点关注有机质含量各异的土壤与若干代表性地衣物种。本次表征采用的观测参数涵盖微气候条件、有机质与无机质含量、落射荧光显微观测结果，以及用于描述微生物与酶活性的相关指标。经评估，细菌现存量（数量与生物量）的直接测量数据，以及通过FDA水解法测得的胞外酶活性数据，是反映微生物学特性的最具价值的参数。数据集结果显示，营养物质水平与微生物活性均存在显著差异。微生境斑块的尺度仅为数平方分米，在极短的空间距离内，环境与微生物学特性即可呈现出宽泛的变化区间。
