Abstract In times of global change, high temperatures can potentiate the negative effects pesticides and other stressors. Here, we evaluated under controlled laboratory conditions effect a moderate increase in temperature combination with ivermectin (an antiparasitic drug used cattle that is excreted dung), an herbicide, parasitic pressure, on reproductive success, development time adult survival dung beetles Euoniticellus intermedius, which are naturally exposed to these We found heat increased number proportion emerged offspring, but ivermectin, herbicide treatments, it had synergistic effects. Moreover, parasitism caused offspring mortality and, synergistically accelerated development. Our results indicate enhance stressors act them, harming beetles, group important ecological economic value natural productive ecosystems. Although sex ratio was not affected by experimental contrasting responses were between males females, supporting idea both sexes use different physiological mechanisms cope same environmental challenges. The combined have insects deepen our understanding why losing beneficial species their functions drastic change.

The brown planthopper, Nilaparvata lugens (Stål), is a major rice pest in various Asian countries, causing significant negative impacts on yield and quality. In this study, we developed novel nanoplatform (NIT@MON@CuS) for pesticide delivery that responds to redox near-infrared light stimuli. consisted of CuS nanoparticles with mesoporous organic silica (MON), loaded nitenpyram (NIT). With an average size 190 nm loading efficiency 22%, NIT@MON@CuS exhibited remarkable thermal response the region, demonstrating excellent photothermal conversion ability stability. vitro release kinetics demonstrated rapid under glutathione conditions, facilitating satisfactory temperature increase accelerated drug release. NIT@MON@CuS-treated group higher mortality N. lugens, increasing from 62 88% compared treated technical after 96 h. Bioassay revealed significantly enhanced toxicity by more than 1.4-fold against both laboratory insecticide-resistant field strains lugens. Furthermore, RT-qPCR results MON@CuS had capability reduce P450 gene expression, thereby improving sensitivity insecticides. These findings suggest holds great potential as intelligent control platform, offering sustainable efficient approach protect crops pests.

Due to their high biodiversity, small water bodies play an important role for freshwater ecosystems. Nonetheless, systematic pesticide monitoring in creeks with a catchment <30 km2 is rarely conducted.In this study, event-driven samples were taken from May until November 2017 and March July 2018 after 20 rain events at three sampling sites areas of <27 the Wetterau, region intensive agriculture Southern Hesse, Germany. Additionally, enriched extracts native campaign used Microtox assay determine baseline toxicity invertebrates over time sum toxic units (STU) calculated compare potential samples.Overall, 37 pesticides 17 transformation products found, whereby herbicide metamitron (79 µg/L) showed highest concentration. Regularly, concentrations peaked level within each event. Within event maximum concentration was mostly reached during first two hours. The time-weighted mean values all between 2.0 µg/L 7.2 µg/L, measured exceeded regulatory acceptable (RAC) 55% least one pesticide.

For sites, significant linear correlation STUinvertebratewas found (r2 = 0.48).The present study suggest (1) current programs underestimate risks posed by exposure aquatic organisms (2) pre-authorization risk assessment schemes are insufficient protect environments.

Abstract Marine heatwaves (MHWs), increasing in duration and intensity because of climate change, are now a major threat to marine life can have lasting effects on the structure function ecosystems. However, responses taxa ecosystems MHWs be highly variable, making predicting interpreting biological outcomes challenge. Here, we review how MHWs, from individuals ecosystems, mediated by fine‐scale spatial variability coastal environment (hereafter, local gradients). Viewing observed through lens ecological theory, present simple framework three ‘resilience processes’ (RPs) which gradients influence MHWs. Local (1) amount stress directly experienced individuals, (2) facilitate adaptation acclimatization populations, (3) shape community composition then influences We synthesize known examples that affected benthic foundation species including kelp forests, coral reefs, seagrass meadows link these varying RPs. series case studies various illustrate differential impacts both temperature other co‐occurring drivers. In many cases, had large effect sizes with several causing 10‐fold difference or more (e.g., survival, coverage). This highlights need for high‐resolution environmental data accurately predict manage consequences context ongoing change. While current tools may capture some already, advocate enhanced monitoring finer scale integration heterogeneity into models. will essential developing effective conservation strategies mitigating future biodiversity loss.

ABSTRACT The rise in global temperatures and increasing severity of heat waves pose significant threats to soil organisms, disrupting ecological balances communities. Additionally, the implications environmental pollution are exacerbated a warmer world, as changes temperature affect uptake, transformation elimination toxicants, thereby vulnerability organisms. Nevertheless, our understanding such processes remains largely unexplored. present study examines impact high on uptake effects fungicide fluazinam springtail Folsomia candida (Collembola, Isotomidae). Conducted under non‐optimum but realistic temperatures, experiments revealed that increased hampered detoxification F. , enhancing toxic fluazinam. High exerted synergistic interactions, reducing candida's reproduction adult mortality beyond what would be predicted by simple addition chemical effects. These findings highlight need reevaluate current risk assessment regulatory framework response climate changes. This research enhances how warming affects toxicokinetics toxicodynamics (TK‐TD) chemicals terrestrial invertebrates. In conclusion, results suggest adjustments threshold values necessary address changing climate.
