指示物种分析(Indicator Species Analysis)是扩增子数据中使用非常广泛的一种经典分析方式,可在许多高分文章主图中见到。通过indicator value 寻找处理的指示微生物(类似于Lefse分析寻找Biomarker),即对处理存在显著正响应的微生物,从而进行处理效应的研究。同时可以基于indicator值来比较微生物和处理关联性大小。一下列举indi...

Indicator species analysisIn order to reveal the effect of disturbance on species composition and detect indicator species for disturbance gradients, we conducted an investigation of urban forest communities along a disturbance gradient in Guangzhou, China. Species richness in the tree layer and ...
The study on pollen rain of characteristic indicator species has important significance for reconstructing paleo_ecological environment.───特征指示种花粉雨研究,对古生态环境重建也具有重要的意义。 scores of ordination were then used for a two way indicator species analysis (TWINSPAN) to the species.─...
species and its relationships with the environmental parameters (temperature, salinity, and turbidity and phytoplankton distribution) in some sandbanks of the Belgian coastal zone was carried out by the use of Two-Way Indicator Species Analysis (TWINSPAN) and Canonical Correspondence Analysis (CANOCO)....
A species whose presence, absence, or relative well-being in a given environment is a sign of the overall health of its ecosystem. By monitoring the condition and behavior of an indicator species, scientists can determine how changes in the environment are likely to affect other species that ar...
