Nutrient limitation or home field advantage: does microbial community adaptation overcome nutrient limitation of litter decomposition in a tropical peatland? (2018)
Journal Article
Hoyos-Santillan, J., Lomax, B. H., Turner, B. L., & Sjögersten, S. (in press). Nutrient limitation or home field advantage: does microbial community adaptation overcome nutrient limitation of litter decomposition in a tropical peatland?. Journal of Ecology, https://doi.org/10.1111/1365-2745.12923

Litter decomposition is an important control on carbon accumulation in tropical peatlands. Stoichiometric theory suggests that decomposition is regulated by elemental ratios in litter while the home field advantage (HFA) hypothesis predicts that deco...

High heterotrophic CO2 emissions from a Malaysian oil palm plantations during dry-season (2017)
Journal Article
Matysek, M., Evers, S., Samuel, M. K., & Sjogersten, S. (in press). High heterotrophic CO2 emissions from a Malaysian oil palm plantations during dry-season. Wetlands Ecology and Management, https://doi.org/10.1007/s11273-017-9583-6

Abstract

Tropical peatlands are currently being rapidly cleared and drained for the establishment of oil palm plantations, which threatens their globally significant carbon sequestration capacity. Large-scale land conversion of tropical peatlands... Read More about High heterotrophic CO2 emissions from a Malaysian oil palm plantations during dry-season.

Root exudate analogues accelerate CO2 and CH4 production in tropical peat (2017)
Journal Article
Girkin, N., Turner, B., Ostle, N., Craigon, J., & Sjögersten, S. (2018). Root exudate analogues accelerate CO2 and CH4 production in tropical peat. Soil Biology and Biochemistry, 117, https://doi.org/10.1016/j.soilbio.2017.11.008

Root exudates represent a large and labile carbon input in tropical peatlands, but their contribution to carbon dioxide (CO2) and methane (CH4) production remains poorly understood. Changes in species composition and productivity of peatland plant co... Read More about Root exudate analogues accelerate CO2 and CH4 production in tropical peat.

Impacts of conversion of tropical peat swamp forest to oil palm plantation on peat organic chemistry, physical properties and carbon stocks (2016)
Journal Article
Tonks, A. J., Aplin, P., Beriro, D. J., Cooper, H., Evers, S., Vane, C. H., & Sjögersten, S. (2017). Impacts of conversion of tropical peat swamp forest to oil palm plantation on peat organic chemistry, physical properties and carbon stocks. Geoderma, 289, https://doi.org/10.1016/j.geoderma.2016.11.018

Ecosystem services provided by tropical peat swamp forests, such as carbon (C) storage and water regulation, are under threat due to encroachment and replacement of these natural forests by drainage-based agriculture, commonly oil palm plantation. Th... Read More about Impacts of conversion of tropical peat swamp forest to oil palm plantation on peat organic chemistry, physical properties and carbon stocks.

Quality not quantity: organic matter composition controls of CO₂and CH₄fluxes in neotropical peat profiles (2016)
Journal Article
Hoyos-Santillan, J., Lomax, B. H., Large, D., Turner, B. L., Boom, A., Lopez, O. R., & Sjögersten, S. (2016). Quality not quantity: organic matter composition controls of CO₂and CH₄fluxes in neotropical peat profiles. Soil Biology and Biochemistry, 103, https://doi.org/10.1016/j.soilbio.2016.08.017

Tropical peatlands represent an important source of carbon dioxide (CO₂) and methane (CH₄) to the atmosphere. However, we do not know where in the peat profile these gases are produced and how controlling factors, such as substrate quality, which can...

Long-term reindeer grazing limits warming-induced increases in CO2 released by tundra heath soil: potential role of soil C quality. Environmental Research Letters, 10(9), Article 094020. https://doi.org/10.1088/1748-9326/10/9/094020

© 2015 IOP Publishing Ltd. The current climate warming in the Arctic may increase the microbial degradation of vast pools of soil carbon (C); however, the temperature sensitivity of decomposition is often highly dependent on the quality of accumulate...

To what extent can zero tillage lead to a reduction in greenhouse gas emissions from temperate soils? (2014)
Journal Article

Soil tillage practices have a profound influence on the physical properties of soil and the greenhouse gas (GHG) balance. However there have been very few integrated studies on the emission of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2...

Consequences of warming on tundra carbon balance determined by reindeer grazing history (2014)
Journal Article

Arctic tundra currently stores half of the global soil carbon (C) stock1. Climate warming in the Arctic may lead to accelerated CO2 release through enhanced decomposition and turn Arctic ecosystems from a net C sink into a net C source, if warming en...
