| Abstract: | The spatio-temporal fluctuations of gut bacteria were monitored in peat-pore water collected from post-mined peatlands in Sarobetsu Mire, northern Japan, where various mammalian species are present, during snow-free periods from spring 2018 to autumn 2019. The composition of gut bacteria was measured by operational taxonomic units (OTUs) in four successional habitats: bare ground, sedgeland, grassland and moss (Sphagnum) mat. Of the 140 peat-pore water samples collected, 129 samples contained gut bacteria. The total of 56 gut -bacteria OTUs found comprised 5.10 % of all the 1,097 taxa, while the gut bacteria accounted for a mean 0.07 % and maximum 1.71 % of relative dominance. The relative dominance of gut bacteria fluctuated seasonally at various taxonomic levels. Although the total read numbers of bacteria did not differ between the four habitats, the read numbers of gut bacteria in Clostridiales, Bacterioidiales and Lactobacteriales tended to show higher dominance in vegetated habitats. These results lead us to hypothesise that vegetation development is related to the richness and abundance of gut bacteria. |
