Soil carbon and nitrogen cycling at the atmosphere–soil interface: Quantifying the responses of biocrust–soil interactions to global change

Global Change Biology, Volume 30, Issue 10, October 2024.
Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.

Vegetative stage and soil horizon respectively determine direction and magnitude of rhizosphere priming effects in contrasting tree line soils

Functional Ecology, Volume 38, Issue 9, Page 1984-2002, September 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tree lines in high latitudes and high altitudes are considered sentinels of global change. This manifests in accelerated encroachment of trees and shrubs and enhanced plant productivity, with currently unknown implications for the carbon balance of these biomes.

Soil microbial biomass under mulch types in an integrated apple orchard from Southern Brazil Biomassa microbiana do solo sob coberturas em pomar integrado de maçãs no Sul do Brasil

Scientia Agricola, 2011
The use of mulching is an alternative to control weeds but there are few studies on its effect on soil quality. In this sense, this study aimed to evaluate the effect of types of mulching on the attributes of microbial carbon, nitrogen and phosphorus in ...

Alteration of the tree–soil microbial system triggers a feedback loop that boosts holm oak decline

Functional Ecology, Volume 38, Issue 2, Page 374-390, February 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In anthropic savanna ecosystems from the Iberian Peninsula (i.e. dehesa), complex interactions between climate change, pathogen outbreaks and human land use are presumed to be behind the observed increase in holm oak decline.

High methane concentrations in tidal salt marsh soils: Where does the methane go?

Global Change Biology, Volume 30, Issue 1, January 2024.
Salt marsh soils can contain high concentrations of methane, but what happens to this gas? There are a few possibilities, including vertical and lateral transport, storage within the soil, and/or oxidation resulting in transport as carbon dioxide or dissolved inorganic carbon.
