Long-term effects of air pollution on microbial communities of moorland peat

Upland peatlands receive the majority of their ecosystem inputs through precipitation, which delivers not only moisture but also atmospheric gases and particulates. Pristine peatlands are characterised by nutrient limitation, leading to the establishment of oligotrophic organism communities both above- and below-ground. Sphagnum mosses in particular thrive, and their presence promotes …

Diverse mycorrhizal representation and bacterial-fungal interactions in an upland peatland vegetation mosaic undergoing restoration

Peatlands are under threat from land management, anthropogenic pollution and climate change. These factors are implicated in severe degradation of peatlands in the southern Pennines of northern England. Significant areas of unconsolidated bare peat are both highly vulnerable to peat erosion and resistant to natural re-vegetation. Restoration efforts during the …

Microbial community responses in degraded peatlands undergoing restoration in the Southern Pennines

Over 70% of upland peatlands in the Southern Pennines are degraded, with extensive areas of bare unconsolidated peat incised with networks of gullies often down to the bedrock. Land management, air pollution and climate change are implicated as major factors leading to loss of vegetation and susceptibility to erosion. Over …

Diversity of planktonic and attached bacterial communities in a phenol-contaminated sandstone aquifer

Polluted aquifers contain indigenous microbial communities with the potential for in situ bioremediation. However, the effect of hydrogeochemical gradients on in situ microbial communities (especially at the plume fringe, where natural attenuation is higher) is still not clear. In this study, we used culture-independent techniques to investigate the diversity of …

Dynamic changes in microbial community structure and function in phenol-degrading microcosms inoculated with cells from a contaminated aquifer

Contamination of aquifers by organic pollutants threatens groundwater supplies and the environment. In situ biodegradation of organic pollutants by microbial communities is important for the remediation of contaminated sites, but our understanding of the relationship between microbial development and pollutant biodegradation is poor. A particular challenge is understanding the in …
