Northern aapa mire complexes are characterized by patterned fens with flarks (wet fen
surfaces) and bog zone margins with Sphagnum moss cover. Evidence exists of a recent …

Extreme climatic events are among the drivers of recent declines in plant biomass and
productivity observed across Arctic ecosystems, known as “Arctic browning.” These events …

Northern mires (fens and bogs) have significant climate feedbacks and contribute to
biodiversity, providing habitats to specialized biota. Many studies have found drying and …

Winter is an important period for ecological processes in northern regions; however,
compared to other seasons, the impacts of winter climate on ecosystems are poorly …

The net ecosystem CO 2 exchange (NEE) drives the carbon (C) sink–source strength of
northern peatlands. Since NEE represents a balance between various production and …

Gross primary production (GPP) is a key driver of the peatland carbon cycle. Although many
studies have explored the apparent GPP under natural light conditions, knowledge of the …

The use of cavity ring-down spectrometer (CRDS) based portable greenhouse gas
analyzers (PGAs) in closed-loop configuration to measure small sample volumes (< 1 l) for …

Peatlands present substantial terrestrial carbon reservoirs actively engaged in land-
atmosphere carbon exchanges. Ongoing variations in carbon dynamics, attributed to global …

Increased soil frost associated with winter climate change could have immediate and carry-
over effects on biological processes in high-altitude forest soils, but the nature of these …

Stress factors such as climate change and drought may switch the role of temperate
peatlands from carbon dioxide (CO2) sinks to sources, leading to positive feedback to global …
