Understanding the variability of post-fire C cycling on heterogeneous landscapes is critical for predicting changes in C storage with more frequent disturbance. We measured C pools and fluxes for 77 lodgepole pine (Pinus contorta Dougl. ex Loud var. latifolia Engelm.) stands in and around Yellowstone National Park (YNP) along a 300-year chronosequence to examine how quickly forest C pools recover after a stand-replacing fire, their variability through time across a complex landscape, and the role of stand structure in this variability. Carbon accumulation after fire was rapid relative to the historical mean fire interval of 150-300 years, recovering nearly 80% of pre-fire C in 50 years and 90% within 100 years. Net ecosystem carbon balance (NECB) declined monotonically from 160 g C m-2 yr-1 at age 12 to 5 g C m 2 yr-1 at age 250, but was never negative after disturbance. Decomposition and accumulation of dead wood contributed little to NECB relative to live biomass in this system. Aboveground net primary productivity was correlated with leaf area for all stands, and the decline in aboveground net primary productivity with forest age was related to a decline in both leaf area and growth efficiency. Forest structure was an important driver of ecosystem C, with ecosystem C, live biomass C, and organic soil C varying with basal area or tree density in addition to forest age. Rather than identifying a single chronosequence, we found high variability in many components of ecosystem C stocks through time; a > 50% random subsample of the sampled stands was necessary to reliably estimate the non-linear equation coefficients for ecosystem C. At the spatial scale of YNP, this variability suggests that landscape C develops via many pathways over decades and centuries, with prior stand structure, regeneration, and within-stand disturbance all important. With fire rotation projected to be < 30 years by mid century in response to a changing climate, forests in YNP will store substantially less C (at least 4.8 kg C/m2 or 30% less).", "keywords": ["Pinus contorta var. latifolia", "13.

The objectives of this study were: (1) to quantify the effect of contrasting methods of organic residue management on tree growth and soil CO2 effluxes in the first 2 years after planting and (2) to evaluate the impact of organic residue manipulations on the mineralization of soil organic matter over the length of the experiment. Three treatments were setup in 0.125 ha plots and replicated in three blocks at the harvesting of a Congolese Eucalyptus stand, resulting in an aboveground organic residue mass ranging from 0 to 6.3 kg m \ufffd 2 . The mineralization of SOM was deduced in each treatment by partitioning sources of soil CO2 effluxes using decomposition experiments and by upscaling specific root respiration. Soil CO2 effluxes were greatly affected by seasons and organic residue manipulation, although there were no significant changes in topsoil water content and topsoil temperature over most of the study period. Aboveground organic residue was the first contributor to soil CO2 efflux in the two treatments with a litter layer. Organic residue management did not significantly influence the mineralization of SOM in our study, probably due to the low quality of Eucalyptus litter, or to the hypothetical lack of dissolved organic carbon transfers from litter to soil. A strong relationship was found between cumulative heterotrophic CO2 efflux and tree growth, supporting the hypothesis that the early growth of Eucalyptus trees in a sandy tropical soil is largely dependent on the nutrients released by the decomposition of organic residues.", "keywords": ["P33 - Chimie et physique du sol", "0106 biological sciences", "Tropical forest plantation", "[SDV]Life Sciences [q-bio]", "MATTER DYNAMICS", "F62 - Physiologie v\u00e9g\u00e9tale - Croissance et d\u00e9veloppement", "Eucalyptus growth", "01 natural sciences", "630", "Harvest organic residue", "NUTRIENT ACCUMULATION", "STAND-LEVEL", "SOIL CARBON BALANCE", "http://aims.fao.org/aos/agrovoc/c_33553", "ABOVEGROUND LITTER", "http://aims.fao.org/aos/agrovoc/c_16118", "http://aims.fao.org/aos/agrovoc/c_35657", "580", "BIOGEOCHEMICAL CYCLES", "2.

The leaching of dissolved organic carbon (DOC) from soils to the river network is an overlooked component of the terrestrial soil C budget. Measurements of DOC concentrations in soil, runoff and drainage are scarce and their spatial distribution highly skewed towards industrialized countries. The contribution of terrestrial DOC leaching to the global\uffe2\uff80\uff90scale C balance of terrestrial ecosystems thus remains poorly constrained. Here, using a process based, integrative, modelling approach to upscale from existing observations, we estimate a global terrestrial DOC leaching flux of 0.28\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.07\uffc2\uffa0Gt\uffc2\uffa0C\uffc2\uffa0year\uffe2\uff88\uff921 which is conservative, as it only includes the contribution of mineral soils. Our results suggest that globally about 15% of the terrestrial Net Ecosystem Productivity (NEP, calculated as the difference between Net Primary Production and soil respiration) is exported to aquatic systems as leached DOC. In the tropical rainforest, the leached fraction of terrestrial NEP even reaches 22%. Furthermore, we simulated spatial\uffe2\uff80\uff90temporal trends in DOC leaching from soil to the river networks from 1860 to 2010. We estimated a global increase in terrestrial DOC inputs to river network of 35\uffc2\uffa0Tg\uffc2\uffa0C\uffc2\uffa0year\uffe2\uff88\uff921 (14%) from 1860 to 2010. Despite their low global contribution to the DOC leaching flux, boreal regions have the highest relative increase (28%) while tropics have the lowest relative increase (9%) over the historical period (1860s compared to 2000s). The results from our observationally constrained model approach demonstrate that DOC leaching is a significant flux in the terrestrial C budget at regional and global scales.We investigated whether the degree of light inhibition of leaf respiration (R) differs among large Eucalyptus saligna grown in whole\uffe2\uff80\uff90tree chambers and exposed to present and future atmospheric [CO2] and summer drought. Associated with month\uffe2\uff80\uff90to\uffe2\uff80\uff90month changes in temperature were concomitant changes in R in the light (Rlight) and darkness (Rdark), with both processes being more temperature dependent in well\uffe2\uff80\uff90watered trees than under drought. Overall rates of Rlight and Rdark were not significantly affected by [CO2]. By contrast, overall rates of Rdark (averaged across both [CO2]) were ca. 25% lower under drought than in well\uffe2\uff80\uff90watered trees. During summer, the degree of light inhibition of leaf R was greater in droughted (ca. 80% inhibition) than well\uffe2\uff80\uff90watered trees (ca. 50% inhibition). Notwithstanding these treatment differences, an overall positive relationship was observed between Rlight and Rdark when data from all months/treatments were combined (R2\uffe2\uff80\uff83=\uffe2\uff80\uff830.8). Variations in Rlight were also positively correlated with rates of Rubisco activity and nitrogen concentration. Light inhibition resulted in a marked decrease in the proportion of light\uffe2\uff80\uff90saturated photosynthesis respired (i.e. reduced R/Asat). Collectively, these results highlight the need to account for light inhibition when assessing impacts of global change drivers on the carbon economy of tree canopies.

Despite scarce empirical evidence, paludiculture is expected to have significant GHG mitigation potential for organic soils. This study provides the first comprehensive dataset on full GHG balances for newly established fen paludicultures over a water table (WT) gradient spanning annual mean WT of \u22120.29 m to +0.04 m, stratified into moderately rewetted conditions (\u22120.30 m < WT < \u22120.10 m) and rewetted conditions (WT \u2265 \u22120.10 m). We used manual and novel automated chambers to measure annual carbon dioxide (CO2), methane and nitrous oxide emissions from five typical fen plant species (Carex acutiformis, Phalaris arundinacea, Phragmites australis, Typha angustifolia and T. latifolia) newly established as peatland biomass crops in three temperate fen peatlands in southern Germany. Our study confirms a significant GHG mitigation potential for the tested plant species and found a C sink function of paludiculture. The results yield preliminary emission factors of \u22120.1 and \u221212.0 t CO2-equivalents ha\u22121 yr\u22121 under moderately rewetted conditions (n=39) and under rewetted conditions (n=43), respectively. We further identify an optimal annual mean WT of \u22120.07 m for maximizing GHG reduction across all plant species and sites with a net C sink achieved at a mean annual WT of \u2265 \u22120.12 m. Presuming the conversion of arable land into paludiculture, a mitigation potential of up to \u221251.9 t CO2-equivalent is attainable per hectare and year. These findings highlight that well-managed paludiculture could make a considerable contribution toward achieving the politically targeted CO2 sink function in the LULUCF sector.", "keywords": ["peatland", " organic soil", " water table", " Carex", " Phalaris", " Phragmites", " Typha", " LULUCF", " preliminary emission factor", " carbon balance"], "contacts": [{"organization": "Bockermann, Carla, Eickenscheidt, Tim, Dr\u00f6sler, Matthias,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.16026838"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.16026838", "name": "item", "description": "10.5281/zenodo.16026838", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.16026838"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-07-17T00:00:00Z"}}, {"id": "2013/ULB-DIPOT:oai:dipot.ulb.ac.be:2013/320463", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-24T16:24:34Z", "type": "Journal Article", "created": "2020-11-29", "title": "Leaching of dissolved organic carbon from mineral soils plays a significant role in the terrestrial carbon balance", "description": "Abstract
