Autor: Daniel N. Schillereff, Richard C. Chiverrell, Jenny K. Sjöström, Malin E. Kylander, John F. Boyle, Jessica A. C. Davies, Hannah Toberman, Edward Tipping

Publikováno v: Communications Earth & Environment, Vol 2, Iss 1, Pp 1-10 (2021)

Increased long-term phosphorus accumulation reduces carbon sequestration in mid-latitude peatlands reliant on atmospheric nutrient sources, according to a synthesis of data from Central Europe, North America, Chile, Sweden and the UK.

Ombrotrophic peatlands are a globally important carbon store and depend on atmospheric nutrient deposition to balance ecosystem productivity and microbial decomposition. Human activities have increased atmospheric nutrient fluxes, but the impacts of

Comparing lake sediment records of landscape macronutrient loadings with N14CP model simulations: 200 years of change in British lakes

Autor: Hannah Toberman, Jess Davies, Neil L. Rose, Richard C. Chiverrell, Edward Tipping, Simon Turner, Daniel Schillereff, John Boyle

To fully understand coupling between P and other macronutrients it is necessary to have both long-term data sets and process models, combining empirical reality with numerical simulation of coupling processes. Here, lake sediment records of N and P f

In this paper we report new data on peat carbon (C), nitrogen (N) and phosphorus (P) concentrations and accumulation rates for 15 sites in the UK. Concentrations of C, N and P measured in peat from five ombrotrophic blanket mires, spanning 4000–10,

Dependence of ombrotrophic peat nitrogen on phosphorus and climate

Autor: Edward Tipping, Peter A. Henrys, Allan Lilly, Hannah Toberman, Rachel Helliwell, John Boyle

Publikováno v: BIOGEOCHEMISTRY

Nitrogen (N) is a key, possibly limiting, nutrient in ombrotrophic peat ecosystems, and enrichment by pollutant N in atmospheric deposition (Ndep, g m-2 a-1) is of concern with regard to peatland damage. We collated data on the N content of surface (

High-frequency fire alters C : N : P stoichiometry in forest litter

Autor: James J. Elser, Tom Lewis, Hannah Toberman, Chengrong Chen

Publikováno v: Global Change Biology. 20:2321-2331

Fire is a major driver of ecosystem change and can disproportionately affect the cycling of different nutrients. Thus, a stoichiometric approach to investigate the relationships between nutrient availability and microbial resource use during decompos

Decomposition ‘hotspots’ in a rewetted peatland: implications for water quality and carbon cycling

Autor: Nathalie Fenner, Chris Freeman, Brian Reynolds, Robert Williams, Hannah Toberman, S. Hughes

Publikováno v: Hydrobiologia. 674:51-66

Restoration of drained peatlands has been promoted to reduce gaseous and aquatic carbon losses; however, there are conflicting reports as to its effectiveness. Here we report “hotspots” of organic matter decomposition as a result of rewetting a d

Turnover of labile and recalcitrant soil carbon differ in response to nitrate and ammonium deposition in an ombrotrophic peatland

Autor: Ian D. Leith, Hannah Toberman, Lorna Dawson, Pauline M. Currey, René van der Wal, David W. Johnson, Rebekka R. E. Artz, Lucy J. Sheppard

Publikováno v: Global Change Biology. 16:2307-2321

The effects of 4 years of simulated nitrogen deposition, as nitrate (NO3 ) and ammonium (NH4 1), on microbial carbon turnover were studied in an ombrotrophic peatland. We investigated the mineralization of simple forms of carbon using MicroRespt meas

Impeded drainage stimulates extracellular phenol oxidase activity in riparian peat cores

Autor: Chris Freeman, Hannah Toberman, Chris D. Evans, Nathalie Fenner, Rebekka R. E. Artz

Publikováno v: Soil Use and Management. 24:357-365

Peat drainage, a common land-use practice in Europe, has been associated with habitat degradation and increased particulate and dissolved carbon release. In the UK, peatland drain blockage has been encouraged in recent years as a management practice

Summer drought decreases soil fungal diversity and associated phenol oxidase activity in upland Calluna heathland soil

Autor: Rebekka R. E. Artz, Chris D. Evans, Hannah Toberman, Chris Freeman, Nathalie Fenner

Publikováno v: FEMS Microbiology Ecology. 66:426-436

Natural moisture limitation during summer drought can constitute a stress for microbial communities in soil. Given globally predicted increases in drought frequency, there is an urgent need for a greater understanding of the effects of drought events
