Although extensive studies have documented earthworm-mediated carbon cycling in croplands and forestlands under optimal temperatures, their impact on carbon dynamics under suboptimal temperatures remains poorly understood, particularly in forest soils. This study conducted a one-year field experiment in a bamboo forest across different temperature phases (warm and cool conditions) to investigate the density-dependent effects of earthworms (<em>Pheretima guillelmi</em>) on soil carbon preservation capacity (CPC), quantified as sequestered SOC, in both topsoil (0–15 cm) and subsoil (15–30 cm). Results indicated that earthworm bioturbation significantly increased coarse particulate organic carbon (by 8.5–24.9 %), fine particulate organic carbon (by 11.3–19.7 %), and mineral-associated organic carbon (by 11.9–22.9 %). Under warm conditions, earthworm bioturbation significantly increased the proportion of large macroaggregates (&gt; 2 mm) by 35.1–62.8 % and promoted aggregate stability (mean weight diameter and geometric mean diameter) in the topsoil. However, under cool conditions, there were no significant changes in aggregate in the topsoil and subsoil. Earthworm-mediated CPC exhibited significant temperature dependence: CPC significantly increased by 12.3–25.3 % under warm conditions but only by 6.0–15.9 % under cool conditions. Notably, earthworms enhanced CPC mainly through improving aggregate stability and promoting SOC fractions during warm conditions. In contrast, the efficacy of earthworm bioturbation diminished as temperatures dropped, with CPC variation becoming primarily affected by SOC fractions. This mechanistic understanding establishes earthworm bioturbation as a temperature-sensitive driver of carbon stabilization and provides theoretical insights into the potential of earthworms to enhance soil carbon protection under climatic variability in agroforestry ecosystems.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"400 ","pages":"Article 110240"},"PeriodicalIF":6.4,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145956484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smooth bromegrass (<em>Bromus inermis, Lyess</em>), a C₃ cool-season grass, dominates cattle grazing pastures in eastern Nebraska and is valued for its productivity and nutritional quality. However, nitrogen fertilization of smooth brome pastures carries nitrate leaching risks, and potential water degradation. Dry Distiller Grains plus Solubles (DDGS), a by-product of corn ethanol production, has emerged as an alternative to mineral fertilization. This study investigated the interactive effects of long-term (2005–2023) pasture management (fertilization and rotational grazing) and climate variability on smooth bromegrass performance over four years (2020–2023). Treatments included mineral nitrogen fertilization, DDGS supplementation, and no fertilization, each under grazed and ungrazed conditions. Biomass (total and live), leaf area index, chlorophyll content, crude protein, acid detergent fiber, neutral detergent fiber, and soil moisture were measured seasonally and across years. Results showed that fertilization consistently produced higher biomass, leaf area index, and crude protein, relative to other treatments, reinforcing its role in sustaining forage productivity. DDGS, while offering a reduced environmental footprint, showed potential in enhancing forage production and quality under average or above average precipitation and soil moisture. However, its efficacy declined during dry years. While long-term fertilization treatment remained the most consistent strategy for sustaining productivity under both ungrazed and rotational grazing systems, DDGS supplementation emerged as a strategic option for regions with adequate growing season precipitation, reducing reliance on mineral fertilizers without compromising yields. These findings emphasize the value of adaptive practices that integrate fertilization and grazing to maintain smooth bromegrass productivity under increasing climate variability.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"400 ","pages":"Article 110216"},"PeriodicalIF":6.4,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145956701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current practices like mowing and grazing considerably alter plant biomass allocation patterns, yet the underlying functional mechanisms remain unclear. To clarify this, we combine community-level leaf and root traits with biomass partitioning analysis across a management gradient (from natural to heavily grazed wetlands) in China's Songnen Plain. Results revealed that agricultural intensification triggered strategic biomass reallocation: aboveground biomass (AGB) and belowground biomass (BGB) decreased 83.1 % and 51.9 % from natural wetlands (NW, 1093.5 g m⁻²) to heavily grazed sites (HG), while root-to-shoot ratio (RSR) increased 12-fold (HG:3.6 vs. NW:0.3). This coincided with the coordinated leaf-root economic strategies: NW favored acquisitive strategies (e.g. peak high leaf area [LA] =1917.1 mm², and specific root length [SRL] = 3219.3 cm g⁻¹), whereas mowed/grazed sites optimized conservation investments (e.g. peak leaf carbon concentration [LCC] = 487.4 g kg⁻¹, and root carbon concentration [RCC] = 391.0 g kg⁻¹), illustrating a functional shift from resource acquisition to conservation. Correlation analysis and stepwise regression identified leaf dry weight (LDW), leaf carbon-to-nitrogen ratio, leaf phosphorus concentration, LA, LCC, root length, specific root area (SRA), RCC, and root surface area (RSA) as key predictors for AGB, whereas BGB was predicted by LCC, LDW and leaf nitrogen-to-phosphorus ratio, RSA, SRA and root phosphorus concentration (RPC). Leaf traits (LA and LDW) and root traits (RCC, RPC, and SRL) were identified as the best predictors of RSR. Variance partitioning analysis showed that leaf-root trait interactions dominated biomass production and allocation (76.9 %-89.8 % of explained variance), underscoring an integrated root-leaf economic network. Structural equation modeling further revealed that the decreased LA indirectly enhanced RSR through positive effects on AGB and synergistic interactions with LDW, SRL and RCC. Contrasting effects of LA-LDW/SRL interactions on BGB further regulated RSR. LA-driven synergies with SRL and trade-offs between RCC and SRL directly modulated RSR. These results collectively demonstrate that trait interaction networks, rather than individual traits, serve as the key driver of biomass production and allocation in agriculturally managed wetlands.
