  • Effects of burning on vegetation, soil physicochemistry and prokaryotic microbial communities in surface and subsurface peat

    November 7, 2024 | Filed under: papers, Research

    Prescribed burning is a common management strategy in peatlands that has the potential to affect soil physicochemistry, alter biogeochemical cycles and trigger changes in vegetation structure. How burning affects prokaryotic community composition across different soil profiles is not well understood. This study explored the effects of prescribed burning on the …

  • Methane production and oxidation potentials along a fen‐bog gradient from southern boreal to subarctic peatlands in Finland

    September 1, 2021 | Filed under: papers, Research

    Methane (CH4) emissions from northern peatlands are projected to increase due to climate change, primarily because of projected increases in soil temperature. Yet, the rates and temperature responses of the two CH4 emission-related microbial processes (CH4 production by methanogens and oxidation by methanotrophs) are poorly known. Further, peatland sites within a fen-bog …

  • Surface Stability in Drylands is Influenced by Dispersal Strategy of Soil Bacteria

    October 9, 2019 | Filed under: papers, Research

    Microbial communities of dryland ephemeral lake bed, dunes, and river channels are characterised – Wind preferentially mobilises specific microbes from soil surface biocrusts – Microbial dispersal adaptations may influence soil stability by promoting or inhibiting adhesion

  • Icelandic glaciers research fieldwork

    June 22, 2016 | Filed under: environment, field recording, photo stories

    We had a long difficult hike to access basal ice of Kvíárjökull because meltwater forced us to skirt a long way along the steep western moraine. It was a spectacular location though and we were quite lucky with the weather which turned bad as we were approaching the car to leave. Working …

  • Seasonal differences in soil CO2 efflux and carbon storage in Ntwetwe Pan, Makgadikgadi Basin, Botswana.

    January 24, 2014 | Filed under: papers

    The carbon cycle in salt pans is complex and poorly understood. Field-based data are needed to improve regional estimates of C storage and land–atmosphere CO2 fluxes from dryland environments where pans are prevalent. This paper provides a first estimate of C stores and CO2 efflux within the salt pan, grassland and woodland …

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

    May 3, 2013 | Filed under: papers

    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 …

  • Long-term partial nitrification in an intermittently aerated sequencing batch reactor (SBR) treating ammonium-rich wastewater under controlled oxygen-limited conditions

    August 15, 2011 | Filed under: papers

    Highlights Development of a novel technology for partial nitrification at ambient temperature. First time to use online NH4-–N measurement as a control parameter for bioreactors. RT-PCR analysis shows the population size of AOB was up to 10% of total bacteria. Intermittent aeration and oxygen-limited conditions sustained partial nitrification. The bioreactor …

Cast from the Past? Microbial Diversity of a Neolithic Stone Circle

We studied the microbial diversity colonizing limestone rock pools at a Neolithic Monument (Arbor Low, Derbyshire, England). Five pools were analyzed: four …

A dataset of acoustic measurements from soundscapes collected worldwide during the COVID-19 pandemic

Political responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium …

Biological soil crusts: spatio-temporal development and ecological functions of soil surface microbial communities across different scales

Editorial for a special issue on Biocrusts in Frontiers in Microbiology can be found here. The special issue consists of 25 articles …

Changes in nitrogen functional genes and microbial populations in soil profiles of a peatland under different burning regimes

Microbes in peatlands provide key ecosystem services and are essential for their role in biogeochemical cycling. Prescribed burning is a common aspect …

Spatial organisation of fungi in soil biocrusts of the Kalahari is related to bacterial community structure and may indicate ecological functions of fungi in drylands

Biological soil crusts, or biocrusts, are microbial communities found in soil surfaces in drylands and in other locations where vascular plant cover …

Bio-protection of cementitious materials below ground: The significance of natural soil environments

This study explores the potential impact of natural soil on concrete crack self-healing in sub-surface structures. Three types of pre-cracked cement mortar …

Bio-self-healing of cementitious mortar incubated within clay soil

The use of bacteria-based self-healing concrete for sub-structures in ground conditions is an area of increasing interest for enhancing the durability and …

Monitoring the bio-self-healing performance of cement mortar incubated within soil and water using electrical resistivity

In research on self-healing concrete, the restorative performance can be evaluated by a wide range of techniques. However, most of these techniques …

Good practice guidelines for long-term ecoacoustic monitoring in the UK

Passive acoustic monitoring has great potential as a cost-effective method for long-term biodiversity monitoring. However, to maximise its efficacy, standardisation of survey …
