Recent peat and carbon accumulation following the Little Ice Age in northwestern Québec, Canada

open access: yesEnvironmental Research Letters, 2019
Peatland ecosystems are important carbon sinks, but also release carbon back to the atmosphere as carbon dioxide and methane. Peatlands therefore play an essential role in the global carbon cycle.

‘Molten‐globule“ state accumulates in carbonic anhydrase folding [PDF]

open access: yesFEBS Letters, 1984
Kinetics of folding and unfolding of bovine carbonic anhydrase B were monitored by circular dichroism, viscometry and esterase activity. It was shown that kinetic intermediate states accumulating in folding process reveal a native‐like compactness and secondary structure but have a symmetrized average environment of aromatic side groups and no esterase

Carbon accumulation in arid croplands of northwest China: pedogenic carbonate exceeding organic carbon [PDF]

open access: yesScientific Reports, 2015
AbstractSoil carbonate (SIC) exceeds organic carbon (SOC) greatly in arid lands, thus may be important for carbon sequestration. However, field data for quantifying carbonate accumulation have been lacking. This study aims to improve our understanding of SIC dynamics and its role in carbon sequestration.

Holocene peat humification and carbon dynamics in the Westerlies-influenced Northwest China

open access: yesEnvironmental Research Letters, 2020
Understanding peat carbon dynamics in the past is of significance, given the uncertainties as to whether there will be an increase or a reduction in carbon as a result of future climate change.

Spatial and temporal variability in blue carbon accumulation in the largest salt marsh in British Columbia, Canada

open access: yesFrontiers in Marine Science
Preserving blue carbon ecosystems, such as salt marshes, for climate change mitigation requires quantifying their carbon (C) dynamics. Boundary Bay (BB) marsh is a 222-ha salt marsh in southern British Columbia, Canada, where construction began in 2023 ...

Holocene carbon accumulation in the peatlands of northern Scotland [PDF]

open access: yesMires and Peat, 2018
The response of peatland carbon accumulation to climate can be complex, with internal feedbacks and processes that can dampen or amplify responses to external forcing.

Recent Changes in Peatland Testate Amoeba Functional Traits and Hydrology Within a Replicated Site Network in Northwestern Québec, Canada

open access: yesFrontiers in Ecology and Evolution, 2020
Northern peatlands, which are highly heterogeneous ecosystems, are a globally important carbon (C) store. Understanding the drivers and predicting the future trajectory of the peatland C store requires upscaling from cores and sites to regions and ...

UNPRECEDENTED CARBON ACCUMULATION IN MINED SOILS [PDF]

open access: yesThe Bulletin of the Ecological Society of America, 2013
Opencast mining often causes permanent damage to soils and vegetation. Here we investigate how resource input and plant colonization promote revegetation and reconstruction of mined soils in central Brazil. We show that: (1) after several decades without vegetation cover, resource input into regoliths prompts the establishment of a diverse plant ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
