Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

Felix J. Elling, Gordon N. Inglis, Nina Davtian, Sarah J. Hurley et autres

Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs). Experimental and empirical …

Legacy of peatland erosion shapes microbial communities during recovery

Fin Ring-Hrubesh, Mike Vreeken, Anne Eberle, Bradley A. Welch et autres

Abstract Human degradation has caused many peatlands worldwide to shift from long-term carbon sinks to net sources. In upland blanket peatlands, erosion disrupts plant-derived carbon input and exposes deep peat, accelerating oxidation of old carbon. The efficacy of restoration in preventing carbon …

Enhanced marine burial of terrestrial organic carbon through the Palaeocene–Eocene Thermal Maximum

Gordon N. Inglis, Jordon Hemingway, Richard Stockey, Emily H. Hollingsworth et autres

The Palaeocene-Eocene Thermal Maximum (PETM) occurred ~56 million years ago and was characterized by large-scale carbon release and transient warming. Erosion and subsequent burial of terrestrial organic carbon in marine sediments could have sequestered organic carbon during the PETM-stabilizing global carbon and …

Bacteriohopanepolyols reveal a methane cycle perturbation during the Paleocene-Eocene Thermal Maximum

Emily H. Hollingsworth, Darci Rush, Ellen C. Hopmans, Elizabeth M. Kennedy et autres

Methane emissions from wetlands have been inferred to increase during past ‘hothouse’ states, notably the Paleocene-Eocene Thermal Maximum (PETM; ∼56 Ma), likely amplifying global warming. Evidence was based upon the stable carbon isotopic composition of bacterial-derived hopanes and hopenes (δ 13 C …

Priority research questions in global peatland science

Alice M. Milner, Michelle M. McKeown, Monika Ruwaimana, Angela Gallego-Sala et autres

Abstract Peatlands are among Earth’s largest terrestrial carbon stores and are crucial for climate regulation, biodiversity conservation, and water security. Yet peatlands worldwide are deteriorating under pressures from climate change and human disturbance. Strategic, globally coordinated research is urgently needed to protect, …

Constraints on Deep Peat Decomposition: Roles of Redox Conditions, Microbial Communities, and Organic Matter Reactivity

Nea Sneddon-Jenkins, Mike Vreeken, Amelia Oakeshott, Simon Cheung et autres

Deep peat is typically more decomposed than shallow peat, and tends to be less available for microbial respiration, producing less methane and carbon dioxide per gram of stored carbon. Understanding why deep peat exhibits slower rates of decomposition – and especially the …

Biomarker approaches for determining past changes in peatland vegetation, pH and biogeochemistry: how they inform the future of tropical peatlands

Richard D. Pancost, Mike Vreeken, Pantelis Prokopiou, Yiming Zhang et autres

Lipid biomarkers are now routinely used in palaeoclimate and palaeoenvironmental investigations of peatlands. However, these applications are mainly focused on vegetation reconstruction, i.e. using n-alkane distributions as a tracer for Sphagnum mosses, and based on biomarker tools largely developed in (Northen hemisphere) …

Environmental Controls on Carbon Stability in Peatlands: Integrating Microbial, Geochemical, and Organic Matter Variation

Amelia Oakeshott, Mike Vreeken, Mark Jenkins, Yiming Zhang et autres

Peatlands are significant terrestrial ecosystems that play a large role in regulating many global processes, resulting in a high social, environmental, and cultural importance. Despite this global distribution, these systems are far from uniform with differences in their hydrology, geochemistry, vegetation, and …
