A regulatory role for phenol oxidase during decomposition in peatlands.
Unique peatland properties, such as their ability to preserve intact ancient human remains (bog bodies) and to store globally significant quantities of atmospheric CO2, can be attributed to their lowExpand

Carbon balance of UK peatlands: current state of knowledge and future research challenges
The retention of peatland carbon (C) and the ability to continue to draw down and store C from the atmosphere is not only important for the UK terrestrial carbon inventory, but also for a range ofExpand

Rapid Turnover of Hyphae of Mycorrhizal Fungi Determined by AMS Microanalysis of 14C
Processes in the soil remain among the least well-characterized components of the carbon cycle. Arbuscular mycorrhizal (AM) fungi are ubiquitous root symbionts in many terrestrial ecosystems andExpand

Identification of groups of metabolically-active rhizosphere microorganisms by stable isotope probing of PLFAs
Abstract We combined microbial community phospholipid fatty acid (PLFA) analyses with an in situ stable isotope 13 CO 2 labelling approach to identify microbial groups actively involved inExpand

Carbon fluxes from plants through soil organisms determined by field 13CO2 pulse-labelling in an upland grassland
Abstract The main findings of research into carbon (C) fluxes from plants to soil micro-organisms using in situ 13CO2 pulse-labelling on upland grassland at the NERC Soil Biodiversity ThematicExpand

UK land use and soil carbon sequestration.
This review explores the role of land use and land use change as a determinant of the soil's ability to sequester and store carbon in the UK. Over 95 percent of the UK land carbon stock is located inExpand

In situ13CO2 pulse-labelling of upland grassland demonstrates a rapid pathway of carbon flux from arbuscular mycorrhizal mycelia to the soil
Summary • The flux of pulse-derived 13C from upland pasture plants to the external mycelium of their arbuscular mycorrhizal (AM) symbionts was traced and quantified over a 7-d post-labelling period.Expand

β-Glucosidase activity in pasture soils
β-Glucosidase is involved in the degradation of cellulose in soils and has potential for monitoring biological soil quality. We assayed β-glucosidase activity in 29 permanent grassland soils fromExpand

Technical considerations for RNA-based stable isotope probing: an approach to associating microbial diversity with microbial community function.
An ongoing challenge within microbial ecology is the development of methodologies that attribute microbial community functions to microbial diversity. One approach, involving the incorporation ofExpand
