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.

引自相关论文《南极（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》的摘要：
本研究对南极海岸陆地环境的微生物生境展开系统描述，重点关注不同有机质含量的土壤以及部分代表性地衣物种。本次描述采用的观测参数包括微气候条件、有机质与无机质含量、落射荧光显微镜观测结果，以及表征微生物与酶活性的相关指标。经检测，通过直接测定细菌现存量（数量与生物量）以及采用FDA水解法检测胞外酶活性所得到的数据，是表征微生物学特性的最具价值的参数。数据显示，不同样地的营养物质水平与微生物活性存在显著差异。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较大的变化跨度。
