Bacterial ratios
Sagova-Mareckova et al. (2021) offers a comprehensive review of compositional indices and ratios as paramount parameters of environmental assessment.
| Ratio | Formula | Reference |
|---|---|---|
| A:S | Alteromonas over SAR11 Clade | Ferrera et al. (2016) |
| BNγ:β | Bacteroidetes, Nitrospira and Gammaproteobacteria over Betaproteobacteria | Garrido et al. (2014) |
| BBC:α | Bacilli, Bacteroidetes and Clostridia over Alphaproteobacteria | Wu et al. (2010) |
| BFγ:α | Bacteroidetes, Firmicutes and Gammaproteobacteria over Alphaproteobacteria | Niu et al. (2018) |
1 Which are the overall distributions of these ratios?
2 Did bacterial ratios vary locally?
3 How did bacterial ratios change over time?
