Bacterial community response to environmental change varies with depth in the surface soil Soil Biol. Biochem. (IF 7.609) Pub Date : 2022-06-17 Kristin M. Barbour, Claudia Weihe, Steven D. Allison, Jennifer B.H. Martiny
Bacterial communities in the organic leaf litter layer and bulk (mineral and organic) soil are sensitive to environmental change. However, despite close interactions between these communities, the leaf litter layer has historically been studied in isolation from the bulk soil. Whether bacterial response to environmental change is uniform throughout the surface soil remains unclear. Here, we simultaneously

Homoacetogenesis competes with hydrogenotrophic methanogenesis for substrates in a peatland experiencing ecosystem warming Soil Biol. Biochem. (IF 7.609) Pub Date : 2022-06-18 Cory LeeWays, Laura L. McCullough, Anya M. Hopple, Jason K. Keller, Scott D. Bridgham
Peatlands contain up to half of terrestrial soil organic carbon (C) while simultaneously emitting the potent greenhouse gas methane (CH4). Global change will alter C biogeochemistry in peatlands, but is hard to predict without a mechanistic understanding of the processes that control anaerobic C cycling. One of the least known anaerobic C cycling pathways in wetland systems is homoacetogenesis, the

The temperature sensitivity (Q10) of soil respiration (Rs) is crucial to assess the carbon (C) budget of terrestrial ecosystems under global warming. The Q10 changes along a climatic gradient as well as its seasonal dynamics remain unclear, and the underlying microbial mechanisms are not well known. Here, the seasonal Q10 of Rs at the northern, middle, and southern sites of a natural temperate mixed

A plant's neighborhood context can alter its interactions with other organisms, but little is known about how these dynamics occur belowground, especially with soil microbes. Microbial communities in rhizosphere soil are influenced by many factors, including abiotic conditions and root-derived signals. In particular, root exudates have strong effects on rhizosphere assembly, respond to changes in abiotic

Belowground insect herbivory is an important interaction that can shape ecological communities above- and belowground. A key component of belowground ecosystems are the arbuscular mycorrhizal (AM) fungi that associate with roots of most terrestrial plants. Despite the shared ecological significance of root herbivores and AM fungi, there is an absence of data on how insect root herbivory affects root-colonising

Nitrogen addition to croplands greatly increases global emissions of the potent greenhouse gas nitrous oxide (N2O). Three ammonia-oxidizing functional guilds constitute the major producers of N2O in agricultural soils, but their relative contributions are still poorly understood, especially the newly discovered and widespread complete ammonia oxidizers (comammox).

Root exudates determine plant's ability to acquire nutrients through influencing plant's interactions with soil microorganisms. Recent studies suggest that plant's associations with beneficial soil microorganisms explain variation in root exudation as plants opt to minimize the exudation cost through such symbiosis. Yet, we have a poor understanding of whether plants change their exudation rates through

Earthworms are invading soil communities worldwide, and their actions as decomposers and ecosystem engineers are vastly impacting many ecosystem functions. In the northern regions of North America, invasive earthworms are often functionally distinct from the native invertebrate fauna and, thus, typically occupy empty trophic niches in soil food webs. Nevertheless, they can affect the co-occurring soil

Nitrous oxide (N2O) emissions from arable soils are predominantly caused by denitrifying microbes, of which fungal denitrifiers are of particular interest, as fungi, in contrast to bacteria, terminate denitrification with N2O. Reduced tillage has been shown to increase gaseous nitrogen losses from soil, but knowledge of how varying tillage regimes and associated soil physical and chemical alterations

Deep-C storage: Biological, chemical and physical strategies to enhance carbon stocks in agricultural subsoils Soil Biol. Biochem. (IF 7.609) Pub Date : 2022-05-17 Erik S. Button, Jennifer Pett-Ridge, Daniel V. Murphy, Yakov Kuzyakov, David R. Chadwick, Davey L. Jones
Due to their substantial volume, subsoils contain more of the total soil carbon (C) pool than topsoils. Much of this C is thousands of years old, suggesting that subsoils offer considerable potential for long-term C sequestration. However, knowledge of subsoil C behaviour and manageability remains incomplete, and subsoil C storage potential has yet to be realised at a large scale, particularly in agricultural

Saltwater intrusion induces shifts in soil microbial diversity and carbon use efficiency in a coastal grassland ecosystem Soil Biol. Biochem. (IF 7.609) Pub Date : 2022-05-11 Robert W. Brown, Jennifer M. Rhymes, Davey L. Jones
Salt accumulation and salinisation of coastal soils is a global issue. Further, climate change is likely to increase the amount of land affected by salinity due to the increasing frequency and severity of coastal flooding and brackish water ingress. The impact of this on the ability of soils to deliver ecosystem services, particularly carbon (C) storage, however, remains unclear. We hypothesized that

The persistence of soil organic carbon (SOC) is influenced by soil physicochemical properties, organic matter quality, and climatic conditions that govern its vulnerability to microbial activity. We compared the susceptibility of newly formed SOC to mineralization in two soils (Andosols) that developed under contrasting precipitation regimes. Soil from the high rainfall region (‘highrain’) had higher

Mechanisms and kinetics of (de-)protection of soil organic carbon in earthworm casts in a tropical environment Soil Biol. Biochem. (IF 7.609) Pub Date : 2022-04-27 N. Puche, C. Rumpel, G. Le Mer, P. Jouquet, A. Mazurier, L. Caner, P. Garnier, T.M. Tran, N. Bottinelli
Earthworms have potential to stabilize soil organic carbon (SOC), but the biophysical controls on SOC dynamics in earthworm casts and the SOC residence time in casts is poorly known. To this end, we aimed to investigate (1) the kinetics of SOC (de-) protection in earthworm casts deposited in a tropical environment and (2) changes in the spatial relationships between fresh particulate organic matter
