{"title":"Successful recovery of native plants post-invasive removal in forest understories is driven by native community features","authors":"Laís Petri,&nbsp;Inés Ibáñez","doi":"10.1002/eap.70012","DOIUrl":"https://doi.org/10.1002/eap.70012","url":null,"abstract":"<p>Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long-term persistence of diverse and functional forest understories is threatened by the impacts of invasive plants. As a result, a common practice is the removal of the agent of invasion. Despite this, we know little about the success of these practices and lack a comprehensive understanding of what intrinsic and extrinsic factors shape the recovery. In a multiyear field experiment, we investigated (Q1) whether native propagule availability drove native community recovery, (Q2) what the characteristics of successfully recovering communities were, and (Q3) under which environmental conditions native community recovery rates were faster. After initial removal of invasives, we seeded native species to manipulate assembly history and mimic restoration practices, we also implemented a repeated, versus once, removal treatment, all in a full-factorial design. We collected data on plant species composition and abundance (i.e., species level percent cover) and on environmental conditions (i.e., light and soil water availability) in the three subsequent summers. Our results show that native community recovery rates were independent of seeding additions or frequency of invasive plant removal. The fastest rates of recovery were associated with high native species richness, native communities with higher values of specific leaf area (SLA), and low drought stress years. Our results suggest that restoration practices post-invasive plant removal should be tailored to enhance natural dispersal, or artificial addition if the resident community is species-poor, of native species with traits compatible with high resource availability, such as species with high SLA. In addition to the importance of the native community characteristics, our results underscore the need for assessing environmental conditions, favoring management practices during years of low drought stress to maximize native community recovery.</p>","PeriodicalId":55168,"journal":{"name":"Ecological Applications","volume":"35 2","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eap.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530081","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}

In the binary system, surfactants suppressed TC transport because of surfactants’ bridging effects; similarly, ferrihydrite colloids also restrained TC mobility stemming from the colloid-associated TC retention. Interestingly, the degree of the inhibitory effects of colloids/surfactants increased with decreasing pH values. Surprisingly, the mutual influences of surfactants and colloids on TC movement displayed a strong pH dependence. Concretely, surfactants strengthened the repressive impacts of ferrihydrite colloids on TC mobility at pH 5.0 caused by the enhanced TC deposition on colloids attached to sand surfaces through the linking effects of surfactants. Nevertheless, at pH 7.0, adding surfactants reduced the repressive effects due to increased TC-colloid mobility and enhanced electrostatic repulsion. Unexpectedly, colloids accelerated the transport of TC with surfactants at pH 9.0 owing to colloids acting as TC carriers, the enhanced TC^2–/TC^– species mobility, and competitive retention. Notably, SDS exhibited a greater effect on individual TC mobility or colloid-mediated TC transport than Rha at a certain pH, which was related to the different surfactant-binding abilities of sand grains/ferrihydrite colloids.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"66 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532361","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}

This study investigated the efficacy and mechanism of the Cl₂-UV process (chlorine followed by UV irradiation) for removing ARGs in various forms. The Cl₂-UV process caused irreversible damage to nearly all ARB at typical disinfectant dosages. In solutions containing only extracellular ARGs (eARGs), the Cl₂-UV process achieved over 99.0% degradation of eARGs. When both eARGs and intracellular ARGs (iARGs) were present, the process reached a 97.2% removal rate for iARGs. While the abundance of eARGs initially increased due to the release of iARGs from lysed cells during pre-chlorination, subsequent UV irradiation rapidly degraded the released eARGs, restoring their abundance to near-initial levels by the end of the Cl₂-UV process. Analysis of the roles in degrading eARGs and iARGs during the Cl₂-UV process revealed that UV, rather than free radicals, was the dominant factor causing ARG damage. Pre-chlorination enhanced direct UV damage to eARGs and iARGs by altering plasmid conformation and promoting efficient damage to high UV-absorbing cellular components. Furthermore, no further natural transformation of residual ARGs occurred following the Cl₂-UV treatment. This study demonstrated strong evidence for the effectiveness of the Cl₂-UV process in controlling antibiotic resistance.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"36 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532477","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}

Epidemiological studies indicate that exposure to O₃ is associated with an elevated risk of kidney disease, a common complication of diabetes. However, the harmful effects of O₃ on the kidneys remain unconfirmed. Herein, we established models for non-diabetic and diabetic mice exposed to 0.5 ppm O₃ for 28 days (4 h/day). We evaluated O₃-induced renal injury and potential mechanisms through analyzing biochemical markers related to renal function, along with histopathology and transcriptomic sequencing of the kidneys. The results showed that O₃ exposure caused glomerular hypertrophy in both non-diabetic and diabetic mice, with mesangial hypercellularity and kidney function impairment specifically in diabetic mice. Furthermore, renal levels of free fatty acids and cholesterol were significantly elevated in O₃-exposed diabetic mice. The important roles of lipid and water-electrolyte metabolism related pathways in O₃-induced kidney damage were found by transcriptome sequencing analysis. The mRNA and/or protein expressions of some genes involved in β-ENaC and AQP2 pathways, which are related to renal water and sodium retention, were changed in diabetic mice following O₃ exposure by real-time quantitative PCR, immunofluorescence staining, and Western blotting. Overall, diabetic mice exhibit a higher vulnerability to adverse effects in the kidney after O₃ exposure than non-diabetic mice. Dysregulation of lipid metabolism and imbalance in water-electrolyte homeostasis have been discovered as key contributing mechanisms. This study offers valuable insights into mechanisms through which ambient O₃ poses renal health risks to both the general subjects and susceptible individuals.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"32 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

A comprehensive sensitivity analysis based on the Sobol's method is conducted to investigate the key impacts of contaminant distribution and degradation rate in the source, cut-off wall retardation factor and Darcy velocity in CGCW. The results show that the performance of the CGCW significantly is controlled by the leakage. The peak contaminant concentration at the outlet of CGCW for large leakage (10^-8 m/s) can be 77.1 times larger than that for small leakage (10^-11 m/s), with a performance deterioration of 98.7%. Additionally, the performance of the CGCW can be significantly enhanced by the source remediation technique. The CGCW will not be broken through when contaminant source degradation rate is larger than 2.9 × 10^-8 /s. Increasing the cut-off wall retardation factors (&gt; 14.7) and decreasing the standard deviation of contaminant source distribution (&lt; 0.1) can also improve the CGCW performance. Moreover, the analytical model coupled with the genetic algorithm is used for the CGCW leakage detection and performance prediction at an abandoned pesticide site based on the monitoring data. Accurate leakage detections in the field (with errors of &lt; 5 m) can be achieved through the analytical solution, which is validated by the non-destructive high-voltage technique. The analytical solution can be an easy-to-use tool for the design, installation and construction of the CGCW at polluted sites.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"84 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528179","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}

Impact of particle size distribution on mercury (Hg) mobility and transformation in the complex aqueous matrices is still unclear. In this study, we considered Hg mine wastes as a natural Hg releasing source to local rivers, and collected water samples from the source to the downstream during high and low flow periods. The water samples were analyzed for Hg morphology, concentration, speciation, and isotope to understand transport and transformation dynamics along the river flows. We found that visible Hg compounds observed by transmission electron microscopy were mainly bound to particles with size fractions of &lt;0.05 and &gt;0.45 μm in the upstream, while the proportion of Hg bound to particles with 0.05-0.45 μm only accounted for 20.0 ± 17.1% of the total Hg (THg). With increasing distance from the mine waste pile in the downstream, nano-colloidal Hg (&lt;0.05 μm) became the dominant from due to settling of large particles and remained constant throughout the whole river. The Hg isotope results also revealed that colloidal Hg could migrate steadily for long distances into the downstream. Most importantly, a significantly positive correlation was observed between the proportion of nano-colloidal Hg to water THg and the proportion of methylmercury (MeHg) to water THg, indicating nano-colloidal Hg as an important substrate for Hg methylation in the river. These results highlighted the pivotal role of the nano-colloidal particles as a significant reservoir for Hg in aquatic environment.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"8 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528180","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}

Water samples from three recreational lakes and a reference reservoir were collected in April and July from both surface and water column layers were analysed to quantify OUVFs concentrations and calculate aquatic risk quotients (RQs). Our results revealed a clear seasonal pattern, with significantly higher OUVF concentrations in July, particularly at Kryspinów reservoir, coinciding with peak tourist activity. IAMC, HMS, and BMDBM were the main contributors to moderate cumulative risk values with localized high-risk values at Kryspinów, while the reference site exhibited consistently low contamination and negligible risks. This study not only establishes a baseline for OUVF contamination in Central European recreational waters but also demonstrates the utility of a multi-depth sampling approach in assessing pollution dynamics.

Herein, this work proposed a conversion of pyrite to ferrous sulfide (FeS) for realizing hyper-enrichment gold concentrates and rapid acid leaching, as well as increasing the added value of Fe and S resources simultaneously. The transition state of Fe_1-xS during FeS formation provides diffusion channel for Au atom transfer and gather. Afterwards, FeS phase is able to dissolve fastly in 30 minutes, inhibiting the formation of S₈ secondary inclusions around gold effectively. Using this method, the gold grade can increase up to 70.70 g/t and the residue yield of the concentrates is reduced to 3.4%. Additionally, high-value Fe- and S- containing products are yielded as green vitriol and sulfur, respectively. Besides, gram-scale concentrates produced by kilogram-scale FeS are evaluated for industrial application, emphasizing process stability and economic sustainability.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"34 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528236","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}
