Table A2.
R values for factors tested via ANOSIM for association with variation in archaeal amoA sequence diversity.
| Factor | Sequences included in analysis |
||
|---|---|---|---|
| Global alignment | Water column sequences | Water associated sequences (water column, groundwater, sea, lakes/rivers) | |
| Habitat (13 levels) | 0.378 (n = 6202) | NA | NA |
| Latitude (low, mid, high) | 0.026 (n = 7138) | 0.296 (n = 440) | 0.049 (n = 984) |
| Temperature (psychrophilic, mesophilic, thermophilic) | 0.170 (n = 2014) | 0.263 (n = 290) | NA |
| Water depth (surface, mid, deep) | NA | 0.464 (n = 898) | NA |
| Salinity (high, low) | NA | NA | 0.576 (n = 1402) |
| Marine versus freshwater / terrestrial1 | 0.422 (n = 6202) | NA | NA |
| Soil/sediment versus aquatic | 0.099 (n = 6202) | NA | NA |
Significant R values (P<0.001) are indicated in bold. Level designations for each habitat are provided; definitions for levels are given in the text. The number of sequences included in each analysis (n) is given below R values. All factors are individually tested in ANOSIM analyses.
NA, not applicable.
1The marine level included sequences associated with aquaria and biofilters, coastal sediments, marine sediments, hydrothermal vents, seas, water column (marine), coral/sponge, and selected wastewater treatment sequences obtained from high-salinity bioreactors in Hong Kong (EU860262–EU860273, EU870438–EU870442). The terrestrial level included sequences associated with soils, lakes and rivers, caves, groundwater, hot springs, and the majority of the wastewater treatment sequences.
