Dissolved organic carbon in water fluxes of Eucalyptus grandis plantations in northeastern Entre Ríos Province, Argentina [PDF]

, 2014
Water fluxes in tree plantations and other ecosystems carry dissolved organic carbon (DOC) provided by atmospheric inputs, autotrophic and heterotrophic metabolisms and from the lysis of dead material. These compounds may be colorless or provide a yellow-

Plant detritus carbon dominates over microbial necromass carbon in topsoil of alpine ecosystems

Communications Earth & Environment
Determining microbial necromass carbon and plant detritus carbon is essential for accurate global soil organic carbon modeling. Yet soil organic carbon precursors are usually ignored in alpine assessments.

Microbial necromass accrual from newly added labile and native soil carbon in the rhizosphere vs. non-rhizosphere of broadleaved and coniferous trees

Geoderma
Microbe-mediated carbon (C) transformation plays a crucial role in the accumulation of soil organic C (SOC). However, microbial conversion efficiency of newly-added labile C and native SOC to necromass remain under-investigated.

Ecological interpretations of nitrogen isotope ratios of terrestrial plants and soils [PDF]

, 2015
Background Knowledge of biological and climatic controls in terrestrial nitrogen (N) cycling within and across ecosystems is central to understanding global patterns of key ecosystem processes. The ratios of 15N:14N in plants and soils have been used as

Decoupled Climatic Drivers of Tree and Ground‐Layer Carbon Uptake in Mountain Ecosystems Around the World

Global Change Biology, Volume 32, Issue 4, April 2026.
Across four continents, we investigated how temperature controls the productivity of high mountain vegetation. We found that the productivity of plants growing close to the ground (< 1 m) tends to be controlled by highly localised “microclimate” temperatures, while the productivity of trees was strongly linked to broader‐scale temperatures.

Legumes’ positive effects on soil carbon magnify via microbial pathways in warm-arid grasslands

Communications Earth & Environment
Legumes play a crucial role in nitrogen cycling; however, it is unclear how this effect is related to soil organic carbon dynamics in grassland across climatic gradients.

Moso bamboo expansion into subtropical coniferous forests reduces microbial carbon use efficiency and destabilizes soil organic carbon

Industrial Crops and Products
Moso bamboo (Phyllostachys edulis) is a fast-growing industrial crop, but its ongoing expansion into native forests may compromise soil organic carbon (SOC) stability.

Community shifts and carbon translocation within metabolically-active rhizosphere microorganisms in grasslands under elevated CO₂ [PDF]

, 2007
International audienceThe aim of this study was to identify the microbial communities that are actively involved in the assimilation of rhizosphere-C and are most sensitive in their activity to elevated atmospheric CO2 in a temperate semi-natural low ...

Phosphorus enrichment mediates the responses of plant lignin and microbial necromass accumulation to nitrogen addition in subalpine forest soil

Geoderma
It is widely recognized that increased nitrogen (N) and phosphorus (P) inputs play critical roles in plant carbon (C) inputs and microbial growth and activity, thereby profoundly affecting the composition and dynamics of soil organic C (SOC).

Drivers of carbon sequestration by biomass compartment of riparian forests [PDF]

, 2015
Riparian forests are expected to play a crucial role in the global carbon (C) cycle but the complex mechanisms of C sequestration in forests remain poorly understood.
