Coupled organic and inorganic carbon dynamics mediated by calcium in semi-arid olive orchards

kaoutar boufous, Matheus Sampaio Carneiro Barreto, Jean Legeay, Mohamed Hijri et autres

Soil organic carbon (SOC) and soil inorganic carbon (SIC) are key carbon reservoirs in semi-arid agroecosystems, yet the mechanisms governing their spatial distribution and interaction in perennial cropping systems remain poorly understood. This study investigated the spatial heterogeneity of SOC and SIC, …

vegetation and tight C-N cycling. Using synchrotron-based micro-FTIR imaging, we observed that PG promoted greater spatial clustering of SOC functional groups and stronger organo-mineral associations with clay minerals, suggesting enhanced SOC stabilization. These findings suggest that stabilization occurred primarily through enhanced physical …

Changes in soil organic matter content and quality in Amazonian mangrove forests converted to shrimp farms

Francisco Ruíz, T. L. D. Ferreira, Matheus Sampaio Carneiro Barreto, Cornelia RUMPEL et autres

Mangroves are highly efficient carbon sinks, yet they are increasingly threatened by aquaculture expansion. Moreover, the long-term impacts of shrimp farming on soil organic matter (SOM) quality and carbon sequestration in Amazonian mangroves remain poorly understood, particularly regarding changes in SOM composition …

Hurricanes and turbulent floods threaten arsenic-contaminated coastal soils and vulnerable communities

Amin Tamadoni, Matthew G. Siebecker, Piyapas Sricharoenvech, Matheus Sampaio Carneiro Barreto et autres

Coastal environments, particularly those adjacent to Superfund sites, are at increased risk of contaminant release during natural disasters, posing serious threats to nearby communities. To investigate this issue, we employed an advanced laboratory flood simulator to impose arsenic-contaminated sediments to turbulent flooding …

Fate of As(V) and Cr(VI) adsorbed on goethite in a mangrove‐microcosm experiment

Matheus Sampaio Carneiro Barreto, Francisco Ruíz, Luís Carlos Colocho Hurtarte, Tiago Osório Ferreira et autres

Abstract Mangroves provide fundamental ecosystem services; however, the growing impact of human activities has resulted in increased pollution pressure, such as chemical contaminants. The redox processes are major biogeochemical players in the fate of contaminants. We investigate the effects of the redox …

Carbon Fate, Iron Dissolution, and Molecular Characterization of Dissolved Organic Matter in Thawed Yedoma Permafrost under Varying Redox Conditions

Matheus Sampaio Carneiro Barreto, Rucha P. Wani, Aleksandar I. Goranov, Tyler D. Sowers et autres

Permafrost soils store ∼50% of terrestrial C, with Yedoma permafrost containing ∼25% of the total C. Permafrost is undergoing degradation due to thawing, with potentially hazardous effects on landscape stability and water resources. Complicating ongoing efforts to project the ultimate fate of …
