We conducted a factorial field experiment examining how day- and night-warming impact the growth, survivorship, and behavior of cabbage white caterpillars (<i>Pieris rapae</i>). In this experiment, the night-warming only treatment showed the highest rates of caterpillar growth, but also showed the highest mortality, the shortest maximum caterpillar lengths, the least accumulated herbivory, and reduced pupation. Caterpillars in the treatments that were not warmed during the day showed daytime-shifted growth, and caterpillars in the combined day- and night-warming treatment showed strongly night-shifted herbivory. Both biotic (e.g., predation risk) and abiotic (e.g., thermal) factors could have contributed to these results. Broadly, these results show the importance of temperature-mediated behavioral changes in diel activity for caterpillar development and survival. These results also support the emerging hypotheses that periods of reduced activity may be important for successful development, that warmer nighttime conditions could limit a temporal thermal refuge for caterpillars, and that increasing temperatures could increase the likelihood of metabolic meltdown. This experiment also illustrates the value of field studies to provide insights into how ectotherms might respond to ongoing climate change.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 7","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536924","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}

Total PAHs varied from 47.1 to 424.4 ng/g during monsoon and 155.9 to 749.4 ng/g during nonmonsoon, which remain below the levels found in most other sediment studies conducted globally. Strong positive correlations were found between PAHs and TOC (<em>r</em> = 0.457, <em>p</em> &lt; 0.05), silt (<em>r</em> = 0.521, <em>p</em> &lt; 0.01), and clay (<em>r</em> = 0.533, p &lt; 0.05), suggesting that PAHs are strongly absorbed onto fine-grained particles. The origin of PAHs in Vembanad Lake is predominantly attributed to diverse anthropogenic activities, including industrial discharges, domestic sewage, port operations, vehicular emissions, oil spills, and runoff from surrounding urban and agricultural areas. Multivariate statistical analysis showed that combustion sources (coal or biomass combustion: 50.69 %), vehicular emissions (48.08 %) and petrogenic sources (1.23 %) are the main sources of PAHs. According to sediment quality assessment, acenaphthylene (Acy) in monsoon seasons exhibited occasional biological effects, while pyrene (Py) did so in the nonmonsoon seasons. Noncarcinogenic risks due to PAHs were very low (HI &lt;1). While carcinogenic risks were moderate, BaP was found to pose significant carcinogenic risks (ILCR &gt;10⁻³).

Twelve adult participants meticulously documented their daily activities, including food intake, across seven consecutive days, while providing all urine voids for analysis. A total of 401 urine samples were collected and analyzed individually (without pooling) to assess temporal variations and exposure associations. Among the eight analyzed BPs, Bisphenol A (BPA) and Bisphenol S (BPS) were detected in over 70 %, with median concentrations ranging from below the limit of quantification (LOQ) to 1.46 ng/mL for BPA and &lt;LOQ to 0.85 ng/mL for BPS, highlighting widespread exposure. While general questionnaires provided limited insight, the multi-day diaries successfully linked BP exposure to both well-known sources-such as food containers, personal care products, detergents, and receipts-and previously underexplored sources, including ointments, medical plasters, sheer tights, wallpapering, vinyl flooring installation, crop cultivation, and food preparation with gloves. These findings demonstrate the power of combining detailed, multi-day activity tracking with individualized biomonitoring to uncover subtle and unconventional chemical exposure routes.

Astragaloside II (AS II), a natural product derived from Astragali Radix (AR), demonstrates dual anti-inflammatory and antioxidant activities. This work systematically evaluates AS II's prophylactic efficacy and molecular pathways in mitigating PM2.5-triggered pulmonary damage using a murine model. Intratracheal PM2.5 suspension (7.5 mg/kg) was applied, with AS II (25 and 50 mg/kg) pretreated via intraperitoneal (i.p.) injection before the pollutant challenge. Results demonstrated that AS II alleviated PM2.5-induced lung injury, mitigated pulmonary edema and inflammation, and reduced levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). AS II upregulated glutathione (GSH) and catalase (CAT) levels while downregulating reactive oxygen species (ROS) and malondialdehyde (MDA). Mechanistically, AS II inhibited the mitogen-activated protein kinase (MAPK) signalling pathway, activated nuclear factor erythroid 2-related factor 2 (Nrf2), enhanced expression of glutathione peroxidase 4 (GPX4), and elevated other antioxidant proteins while suppressing ferroptosis and oxidative stress markers. To further validate the role of ferroptosis, RSL3—a small-molecule ferroptosis agonist that binds and inactivates GPX4—was employed. The protective efficacy of AS II against lung injury was effectively counteracted by RSL3-induced GPX4 inactivation. Collectively, AS II protects against PM2.5-induced pulmonary injury by modulating the MAPK/NRF2/GPX4 signaling axis to inhibit ferroptosis, thereby providing a novel therapeutic strategy for the treatment of PM2.5-associated pulmonary diseases.</div></div>","PeriodicalId":303,"journal":{"name":"Ecotoxicology and Environmental Safety","volume":"302 ","pages":"Article 118613"},"PeriodicalIF":6.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535662","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}
