Characteristics and descriptions of study sites.
Fig 1.
Richness and diversity of prokaryote 16S rRNA communities in New Zealand wetlands.
a) Rarefied richness and diversity curves; b) range of richness and diversity values for individual samples from each core (small circles) plotted against pH. Large circles represent mean values for each site or distinct soil/sediment unit within a site. Solid lines represent fitted quadratic curves with dashed lines representing the lower and upper bounds of 95% confidence intervals. Note that values in B are based on a sequencing depth of 4000 reads.
Fig 2.
Relationship between Archaea: Bacteria ratio (assigned reads) and depth within seven New Zealand wetlands.
For ombrotrophic bogs, colours reflect wetland condition: Red, Dunearn (most modified condition); Orange, Bayswater (moderate condition); Green, Awarua (most intact condition).

Archaea community composition at the taxonomic level of class.

Bacteria community composition at the taxonomic level of phyla.
Fig 5.
Bray-Curtis PCA (total prokaryote community composition) scores plotted against depth.
a) axis 1 (15.14% variation explained); b) axis 2 (8.77% variation explained); c) axis 3 (6.48% variation explained).
Fig 6.
NMDS ordination of samples based on metabolic pathway composition.
Coloured by a) locality and b) depth. c) Clusters assigned using hierarchical cluster analysis (cut at k = 7) plotted against depth.
Fig 7.
Differences in the relative abundance of metabolic pathways in three New Zealand ombrotrophic bogs along a wetland condition gradient.
a) aerobic respiration; b) denitrification; c) sulfate reduction. Red, Dunearn (most modified condition); Orange, Bayswater (moderate condition); Green, Awarua (most intact condition). Horizontal line marks 75 cm depth.
Fig 8.
Differences in the relative abundance of metabolic pathways related to the carbon cycle in three New Zealand ombrotrophic bogs along a wetland condition gradient.
a) carbon fixation; b) fermentation; c) methanogenesis; d) methanol to CO2. Red, Dunearn (most modified condition); Orange, Bayswater (moderate condition); Green, Awarua (most intact condition). Horizontal line marks 75 cm depth.
