This study uses crisp-set Qualitative Comparative Analysis (csQCA) of 25 conservation conflict cases from the Environmental Justice Atlas to identify the pathways through which defenders effectively resist unjust conservation practices. We identify four causal pathways to successful mobilization: two epistemic strategies, where defenders use alternative knowledge mobilization to either strengthen legal claims or build broad coalitions; one preventive strategy focused on early mobilization; and a comprehensive strategy drawing on nearly all conditions, except direct action. Across all pathways, alternative knowledge mobilization, such as defender-led health studies and ecological assessments, plays a central role in successful mobilization, while direct action tactics were notably absent in all successful pathways. These findings challenge assumptions about confrontation as a necessary ingredient for effective resistance and advance new insights into how knowledge politics shape just outcomes in conservation conflicts. As the global conservation community intensifies efforts to safeguard biodiversity and uphold the rights of affected communities, centering the strategies and experiences of environmental defenders is essential to ensuring equitable and effective conservation.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"93 ","pages":"Article 103030"},"PeriodicalIF":8.6,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144338250","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}

The SEM and TEM analyses indicated Cd-induced stomatal injury and massive damage at subcellular level. Confocal microscopic visualization clarified the ROS accumulation and cell death by Cd-mediated redox imbalance. However, application of Ag-NPs effectively reduced Cd bioaccumulation (BCF) and root-to-shoot Cd translocation (TF) rate. Moreover, the Ag-NPs application (Cd + Ag-NPs) mitigated Cd-induced oxidative damage by improving the activities/levels of antioxidants such as APX, AsA, and SOD by 248.45%, 132.67% and 29.43%, respectively, compared with Cd only. The Ag-NPs also upregulated the expression of genes related to growth, chlorophyll, carotenoid biosynthesis, and antioxidative defense. Therefore, Ag-NPs can be employed as a sustainable approach to reduce environmental toxic impact of Cd and also to ensure food safety.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"240 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144329184","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}

This progressive accumulation is facilitated by the fact that macroplastics released in the environment progressively fragment into micro and nanoplastics, which are easily taken up by a wide range of living organisms. As these micro and nanoplastics are particulate materials, they are handled in these living organisms by specialized phagocytic cells, namely macrophages in vertebrates, opening the possibility that plastics accumulating in macrophages may elicit a variety of responses. Thus, one way of alleviating such accumulation in macrophages and in other cell types would be to use biodegradable plastics. Polycaprolactone is a biodegradable plastic showing favorable degradation characteristics in several environments. We thus investigated the responses of macrophages upon treatment with polycaprolactone nanobeads, using a combination of proteomics and validation experiments, and compared these results to the ones induced by polystyrene nanobeads. Many changes detected by proteomics, for example in the mitochondrial, lysosomal or reticulum proteins did not induce detectable physiological consequences. A slight decrease in the phagocytic capacity of polycaprolactone-treated cells was detected, but not for polystyrene-treated cells. We also showed that polycaprolactone nanobeads degrade within a few days in macrophages, modulating the macrophage responses. The derease in phagocytosis disappeared, while polystyrene induced a delayed surge in the phagocytic response. A delayed decrease in the secretion of pro-inflammatory cytokines was also observed in of polycaprolactone-treated cells, which may be linked to the release of hydroxycaproic acid.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"12 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319336","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}

While silica nanoparticles (SiNPs) have been shown to enhance plant tolerance to waterlogging, their mechanisms of action in ginger remain poorly understood. This study aims to elucidate the role of SiNP200 in mitigating waterlogging stress, providing a foundation for utilizing SiNPs to counteract the detrimental effects of abiotic stress in plants. The results showed that waterlogging stress had adverse effects on the growth, photosynthetic and plant water content of ginger seedlings. SiNP200 treatment significantly increased the net photosynthetic rate, reduced the oxidative damage of leaf cells, and alleviated plant senescence and wilting. Additionally, SiNP200 application can increase leaf relative water content by 9.61% under waterlogging stress, thus maintain osmotic balance and increase water state of the whole plant. Besides, SiNP200 enhanced root growth and significantly increased root hydraulic conductivity (by up to 113.46%) in ginger seedlings. This improvement was further supported by the upregulated expression of aquaporin genes, including ZoPIP1;3, ZoTIP2;2, and ZoNIP2;6, which collectively facilitated water absorption and elevated tissue water content. Under waterlogging conditions, the activities of anaerobic respiratory enzymes, such as alcohol dehydrogenase (ADH) and lactate dehydrogenase (LDH), significantly increased. Following SiNP200 treatment, the activities of ADH and LDH were further enhanced, potentially intensifying the anaerobic respiration in ginger seedling roots. This enhancement may enable the roots to better adapt to the dramatic reduction in soil oxygen levels, thereby improving their tolerance to waterlogged environments. Therefore, this study will help to better understand the role of SiNP200 in alleviating waterlogging stress and provide foundation for the use of SiNPs in plants to offset the negative effects of abiotic stress.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"43 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311980","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}

However, and given its early days, concerns regarding their risks to human health and environment remain to be investigated. New Approach Methodologies (NAMs) are on high demand, e.g. omics, allowing to move beyond standard hazards, providing insights into the mechanism of toxicity of chemicals. The toxicity of WELGRO®, a commercial nanoagrochemical, was studied in the non-target soil invertebrate Enchytraeus crypticus (Oligochaeta) but the mechanisms are unknown. The aim of the present study was to investigate the underlying mechanisms that lead to the toxicity of WELGRO®, this based on high-throughput transcriptomic analysis (4x44K microarray), measuring the Differentially Expressed Genes (DEGs). The animals were exposed in the natural soil LUFA 2.2, for 2 and 21 days, to control (un-spiked soil) plus 100-1000 mg WELGRO®/kg, the lower dose corresponding to realistic topsoil concentrations, based on the recommended application rates. Results showed that gene transcription was clearly time dependent. The impacts after immediate exposure (2d) were highest at lowest concentration while the opposite occurred for the longer exposure time (21d), at highest concentration. The main findings showed that, regardless of the exposure period, ABC transporters were shut down, leading to accumulation of waste products and further endoplasmic reticulum (ER) stress as a possible cause of toxicity. DNA damage seems to also occur as part of the impact. Immediate exposure (2 days) affected neurotoxicity related pathways, although probably a transient/ reverted impact, as this was no longer observed after 21 days. Indications are that WELGRO® is probably up-taken (at cellular level) by clathrin-mediated endocytosis – a nano-related pathway. This study provides the first insights into the mechanisms of toxicity of a commercially available nanoagrochemical, based on a realistic exposure scenario for a non-target species. Our findings support the principle that risk assessment of nanoagrochemicals should consider the nano-specific features of those products.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"23 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311979","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}

This research examined the lethal and behavioral effects of Cinnamomum verum (cinnamon) extracts on house flies, employing an age-stage two-sex life table methodology to evaluate life table parameters. The analysis utilizing gas chromatography-mass spectrometry (GC-MS) revealed significant phytochemicals present in cinnamon bark, such as cinnamaldehyde and eugenol, which are recognized for their insecticidal and behavioral effects in insects. Acute toxicity assessments demonstrated lethal concentrations (LC₅, LC₂₅, and control) of cinnamon extracts, significantly affecting developmental and reproductive parameters. Interestingly, lower concentrations (LC₅) promoted fecundity and intrinsic growth rates compared to higher concentrations (LC₂₅), suggesting a biphasic response that aligns with the concept of pesticide-induced hormesis. Furthermore, oviposition preference trials confirmed a concentration-dependent deterrent effect of cinnamon extracts, with higher doses significantly reducing egg-laying behavior in gravid females. This research has included traditional GC-MS-based phytochemical screening by incorporating comprehensive biological and molecular assessments, offering a more integrated approach for biopesticide identification.

Integrating transcriptomics, proteomics, and metabolomics data—known as multi-omics data integration—is a powerful strategy for uncovering the molecular mechanisms underlying the effects of CBNs on a plant's molecular level, providing detailed insights into their biological impacts. Here, we combined transcriptomic (RNA-Seq) and proteomics (Tandem MS) data to understand mechanisms of improvement of tolerance to salt stress in tomato plants exposed to CBNs (carbon nanotubes (CNTs) and graphene). At the proteome level,exposure to CNTs resulted in complete restoration of the expression of 358 proteins and partial restoration of the expression of 697 proteins in tomato seedlingsexposed to salt stress.Similarly, exposure to graphene resulted in the complete restoration of 587 proteins and the partial restoration of 644 proteins affected by salt stress. In the integrative analysis of transcriptomics and proteomics data86 upregulated and 58 downregulated features showed the same expression trend (restoration expression towards normal level) at both “omics” levels in NaCl-stressed seedlings exposed to CBNs. Our data indicated that elevated salt tolerance of CBN-treated tomato plants can be associated with the activation of MAPK and inositol signaling pathways, enhancing the ROS clearance, stimulation of hormonal and sugar metabolisms, regulation of water uptake through work of aquaporins, regulation of the production of heat-shock proteins, and promotion of the production of secondary metabolites with defense functions.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"147 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319335","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}
