Peatland Mid-Infrared Database 1.0.0 Open
Systematic collections of peat mid-infrared spectra and other peat properties are scarce, but useful to understand peat chemistry and develop spectral prediction models. The Peatland Mid-Infrared Database ('pmird') stores 3877 mid-infrared…

Peat oxic and anoxic controls of <i>Sphagnum</i> decomposition rates in the Holocene Peatland Model decomposition module estimated from litterbag data Open
The Holocene Peatland Model (HPM) is a widely applied model for understanding and predicting long-term peat accumulation, but it is difficult to test due to its complexity, measurement errors, and lack of data. Instead of testing the compl…

A synthesis of <i>Sphagnum</i> litterbag experiments: initial leaching losses bias decomposition rate estimates Open
Our knowledge of the magnitude and controls of Sphagnum decomposition rates is derived to a large extent from litterbag experiments that do not explicitly consider initial leaching losses. Previous research on vascular plants suggests that…

Patterns and drivers of organic matter decomposition in peatland open-water pools Open
Peatland pools are unvegetated, inundated depressions that cover up to 30 % of the surface of many temperate and boreal peatlands and that are net carbon (C) sources within C-accumulating ecosystems. The emission of carbon dioxide (CO2) an…

Abstract. Decomposition is one of the major controls of long-term sequestration of carbon in northern peatlands. Our knowledge of the magnitude and controls of decomposition rates is derived to a large extent from litterbag experiments. Si…

Underestimation of Anaerobic Decomposition Rates in Sphagnum Litterbag Experiments by the Holocene Peatland Model Depends on Initial Leaching Losses Open
The Holocene Peatland Model (HPM) is a widely applied model to understand and predict long-term peat accumulation. Here, we test whether the HPM can predict decomposition of available Sphagnum litterbag data along a gradient from oxic to a…

Horticultural additives influence peat biogeochemistry and increase short-term CO2 production from peat Open
Aims Peat is used as a major ingredient of growing media in horticulture. Peat extracted from bogs can be acidic and low in nutrient availability and is therefore mixed with liming agents, nutrients, surfactants, perlite and so on. This st…

Comment on Hodgkins et al. (2018) Open
Hodgkins et al. (2018) used mid infrared spectra (MIRS) to make inferences about the stability of peat against decomposition along a latitudinal gradient from the tropics to northern latitudes. Recently, we have shown that these spectral p…
