Coastal seagrass, mangrove and salt-marsh ecosystems—also termed blue-carbon
ecosystems—play an important role in the global carbon cycle. Much of the organic carbon …

The projected loss of soil carbon to the atmosphere resulting from climate change is a
potentially large but highly uncertain feedback to warming. The magnitude of this feedback …

Soil organic carbon (SOC) can be defined by measurable chemical and physical pools, such
as mineral-associated carbon, carbon physically entrapped in aggregates, dissolved …

Climate models have evolved into Earth system models with representation of the physics,
chemistry, and biology of terrestrial ecosystems. This companion book to Gordon Bonan's …

Biogeochemical processes are of tremendous importance for determining the fate of many
organic and inorganic compounds in the subsurface. Most global elemental cycles involve …

Climatic, atmospheric, and land-use changes all have the potential to alter soil microbial
activity, mediated by changes in plant inputs. Many microbial models of soil organic carbon …

Increases in carbon (C) inputs to soil can replenish soil organic C (SOC) through various
mechanisms. However, recent studies have suggested that the increased C input can also …

Large model uncertainty in projected future soil carbon (C) dynamics has been well
documented. However, our understanding of the sources of this uncertainty is limited. Here …

Explicit consideration of microbial physiology in soil biogeochemical models that represent
coupled carbon–nitrogen dynamics presents opportunities to deepen understanding of …

Terrestrial ecosystems have absorbed roughly 30% of anthropogenic CO 2 emissions over
the past decades, but it is unclear whether this carbon (C) sink will endure into the future …
