Pre-exposure to chemicals increases springtail vulnerability to high temperatures

Global climate change is increasing the frequency and intensity of heat waves, posing a significant threat to ectothermic organisms. Concurrently, chemical pollution, including heavy metals and pesticides, remains a pervasive environmental stressor. This study investigates the effects of sublethal copper and fluazinam exposure on the thermal tolerance of the soil-dwelling springtail, Folsomia candida. Using a Thermal Death Time (TDT) framework, we assessed how pre-exposure to these toxicants at two acclimation temperatures (20 °C and 24 °C) influenced survival under heat stress. Our findings indicate that toxicant exposure reduced heat tolerance at moderately high temperatures (32.5 °C) but had negligible effects at extreme temperatures (37 °C). Acclimation at 24 °C mitigated the negative effects of both toxicants, suggesting an enhanced capacity for cellular homeostasis under warm conditions. Additionally, soil type influenced thermal tolerance, highlighting the importance of environme..., , # Data from: Pre-exposure to chemicals increases springtail vulnerability to high temperatures

全球气候变化正导致热浪的发生频率与强度持续攀升，对变温生物构成了严峻威胁。与此同时，包括重金属与农药在内的化学污染仍是广泛分布的环境胁迫因子。本研究旨在探究亚致死剂量铜与氟啶胺(fluazinam)暴露对土壤栖息弹尾虫白符跳虫(Folsomia candida)耐热性的影响。本研究采用热致死时间(Thermal Death Time, TDT)框架，评估了在两种驯化温度（20℃与24℃）下预先暴露于上述毒物，如何影响受试生物在热胁迫下的存活率。结果显示，毒物暴露会在中等高温（32.5℃）下降低受试生物的耐热性，但在极端高温（37℃）下几乎无显著影响。在24℃条件下进行驯化可缓解两种毒物带来的负面影响，提示温暖环境下细胞稳态的调控能力得到增强。此外，土壤类型会对耐热性产生影响，凸显了环境因子的重要性……
