Bacterial and fungal representation and interactions in a former degraded 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 ombrotrophic 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 …

Bacterial and fungal communities in a degraded ombrotrophic peatland undergoing natural and managed re-vegetation

The UK hosts 15-19% of global upland ombrotrophic (rain fed) peatlands that are estimated to store 3.2 billion tonnes of carbon and represent a critical upland habitat with regard to biodiversity and ecosystem services provision. Net production is dependent on an imbalance between growth of peat-forming Sphagnum mosses and microbial …

Soil microbes of the Kalahari and the Pennines

Soil is a non-renewable resource which sustains life and delivers countless beneficial ecosystem services that we need and take for granted. The microbial diversity of soil dwarfs above-ground plant diversity, but is intimately linked with it. Whilst macroscopic ecology is a well-developed discipline that supports our efforts to manage and …

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 …

Niche partitioning of bacterial communities in biological crusts and soils under grasses, shrubs and trees in the Kalahari

The Kalahari of southern Africa is characterised by sparse vegetation interspersed with microbe-dominated biological soil crusts (BSC) which deliver a range of ecosystem services including soil stabilisation and carbon fixation. We characterised the bacterial communities of BSCs (0–1 cm depth) and the subsurface soil (1–2 cm depth) in an area typical of …
