SOC influences soil fertility and structure and is controlled by various factors, including land use, land management practices, and climate change. Biological invasion is a significant yet controversial factor that can alter SOC levels. We conducted a meta-analysis of 445 observations from 61 published reports and followed up with field surveys to clarify the impact of plant invasion on SOC. Our results indicated that plant invasion leads to a 29% increase in microbial biomass carbon (MBC), which is one of the key fractions of SOC. Specifically, among different ecosystems, plant invasion caused MBC increases of 59% in estuaries, 59% in alluvial land, 53% in wetlands, and 80% in orchards. Furthermore, invasion by plants from the Asteraceae family resulted in a 33% increase in MBC, whereas invasion by plants from the Lythraceae family caused a 72% increase in MBC. Our field survey also revealed that plant invasion elevated the soil MBC content relative to the occurrence of native plants or bare ground. Overall, these findings suggest that plant invasion impacts soil carbon, especially by increasing MBC, which may in turn affect future invasions. These effects are influenced by the type of invasive species, ecosystem type, and soil layer depth, highlighting the complex role of biological invasion in the global carbon cycle.</p>\u0000 </div>","PeriodicalId":175,"journal":{"name":"Global Change Biology","volume":"31 3","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that high ESG performance is significantly associated with the widening of the intra-firm pay gap. Further analysis indicates the increasing gap mainly comes from escalating management compensation, while the rank-and-file employees' salaries remain unchanged. We explore three mechanisms behind the above relationship: reducing agency costs, enhancing managerial capabilities, and improving managerial reputation. Furthermore, our analyses suggest that the effect of ESG performance on the intra-firm pay gap is intensified when the majority shareholder wields greater influence and rank-and-file employees have less bargaining power.

We investigated the effects of ditch border type (conventional vs. regenerative) on litter decomposition (standardized litter using Tea Bag Index, and locally collected leaf and root litter), vegetation composition, litter quality, and soil characteristics along transects that extended from the water's edge into the adjoining field (40 cm, 80 cm, 360 cm and 640 cm) in a peat polder in North Holland, the Netherlands. The decomposition rate of standardized litter was unaffected by ditch border type, however the stabilization factor was 43% and 35% lower in regenerative ditch borders at 40 cm and 80 cm from the water's edge, respectively. Leaf litter collected from regenerative borders decomposed 75% slower than leaf litter from conventional borders. Regenerative soils were higher in organic matter content, carbon and nitrogen content, and soil moisture content, and lower in bulk density and soil compaction. This pattern was related with a lower decomposition rate and stabilization of standardized litter. Changes in litter decomposition are predominantly driven by a lower leaf litter quality produced at regenerative borders. Efforts to reduce carbon emissions should therefore focus on reducing decomposition rates by creating conditions that stimulate plant species producing litter of a lower quality.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"378 ","pages":"Article 124725"},"PeriodicalIF":8.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
