We present the first assessment of microbial cell discharge from sediment-laden glacier basal ice. At Svínafellsjökull, a temperate valley glacier in Iceland, approximately 1017 cells a−1 are transferred through basal ice to the proglacial environment, and between 101 and 106 cells g−1 basal ice were cultured from our samples under …
Sub-glacial microbes are receiving increased attention due to their central roles in storage and release of greenhouse gases, such as methane and CO2. Climate change driven warming and resulting glacier retreat exposes bedrock that can contribute to soil formation in which subglacial-released microorganisms may play a crucial role. Basal ice, …
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 …
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 …
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 …
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 …

This week I am attending the 33rd New Phytologist symposium (Networks of Power and Influence) with Robin Sen and Francis Brearley from MMU. I will present a poster of work supported by MMU and Moors for the Future. The poster shows a preliminary network analysis of bacterial and fungal microbial …
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 …
