A clear definition of carbon sequestration in soils is necessary to quantify soil's role in climate change mitigation accurately. Don et al. (2023) proposed defining carbon sequestration as "[the] Process of transferring carbon from the atmosphere into the soil through plants or other organisms, which is retained as soil organic carbon resulting in...

Decomposition of senescent plant tissue (litter) is the first step in the terrestrial carbon (C) cycle and a critical component determining the C balance at the ecosystem scale. Generally, degradation of plant litter is thought to be biotically mediated. But, more recently photodegradation was identified as a control of litter decomposition, that i...

Plant litter decomposition stands at the intersection between carbon (C) loss and sequestration in terrestrial ecosystems. During this process organic matter experiences chemical and physical transformations that affect decomposition rates of distinct components with different transformation fates. However, most decomposition studies only fit one-p...

Plant litter decomposition in terrestrial ecosystems involves the physical and chemical breakdown of organic matter. Development of databases is a promising tool for achieving a predictive understanding of organic matter degradation at regional and global scales. In this paper, we present aridec, a comprehensive open database containing litter mass...

RESUMEN. Conocer la estructura y el funcionamiento de la fracción subterránea de la vegetación es fundamental para comprender numerosos procesos que ocurren en distintos niveles de organización. Sin embargo, dicha fracción fue menos estudiada que su contraparte aérea, principalmente por el gran esfuerzo que demanda muestrearla a campo y procesarla...

In most temperate grasslands, cattle grazing can promote physiognomic changes on plant communities, as well as changes in species growth patterns. Through these changes in vegetation, cattle grazing can generate changes in allocation to total, fine and coarse root biomass, which can further affect ecosystem processes. The objective of this work was...
