Transcriptomics predicts Artificial Light at Night’s (ALAN) negative fitness effects and altered gene expression patterns in the midge Chironomus riparius (Diptera:Chironomidae)

The emission of artificial light at night (ALAN) is rapidly increasing worldwide. Yet, evidence for its detrimental effects on various species accumulating. While the ALAN phenotypic traits have been widely investigated, molecular level are less well understood. Here we aimed to integrate transcriptomic and level. We tested these Chironomus riparius, a multivoltine, holometabolous midge with high ecological relevance which genomic resources available. performed life-cycle experiments in exposed midges constant control conditions one generation. observed reduced fertility under from predicted population size decline 1% after 200 days. analysis revealed expression changes genes related circadian rhythmicity, moulting, catabolism oxidative stress. From hypothesised that ALAN, stress increased, moulting begins earlier. were able confirm both hypotheses two posthoc experiments, showing transcriptomics can be powerful tool predicting higher traits.

Nanoparticles for Sustainable Agriculture: Assessment of Benefits and Risks

Agronomy, Год журнала: 2025, Номер 15(5), С. 1131 - 1131

Опубликована: Май 4, 2025

Nanotechnology is rapidly emerging as a transformative force in agriculture, offering innovative solutions to support sustainable crop production. This review examines the interactions between nanoparticles (NPs) and plants, elucidating underlying mechanisms that govern NP uptake, translocation, at cellular level. We explore how NPs influence key physiological processes modulate plant defense responses both biotic abiotic stresses, highlighting their potential for enhancing stress resistance. The diverse applications of agriculture are also comprehensively surveyed, encompassing targeted delivery nutrients, enhanced biocontrol phytopathogens, engineering improved tolerance environmental extremes. address broader socioeconomic implications widespread use critically evaluating ecotoxicity, impacts on biodiversity, associated economic costs benefits. Finally, we offer perspective future directions research, including trends synthesis characterization, challenges implementation, prospects large-scale deployment nanotechnology-enabled agricultural solutions. provides rigorous balanced assessment nanotechnology revolutionize practices while acknowledging need responsible innovation risk mitigation.

Metal-rich lacustrine sediments from legacy mining perpetuate copper exposure to aquatic-riparian food webs

Integrated Environmental Assessment and Management, Год журнала: 2025, Номер unknown

Abstract Historic copper mining left a legacy of metal-rich tailings resulting in ecological impacts along and within Torch Lake, an area concern the Keweenaw Peninsula, Michigan, USA. Given toxicity to invertebrates, this study assessed influence on present day nearshore aquatic terrestrial ecosystems. We measured metal (Co, Cu, Ni, Zn, Cd) metalloid (As) concentrations sediment, pore water, surface larval adult insects, two riparian spider taxa collected from Lake nearby reference lake. Overall, elevated concentrations, particularly were all sediment samples some water Lake. For instance, Cu ∼200% higher than lake exceeded predicted effects by at least ninefold. Within insect tissues, we observed 160% lake, was only element above Adult insects both lakes had similar irrespective exposure levels. Yet found 100% spiders, demonstrating risk insectivores across aquatic-terrestrial boundary. Our results highlight that other metals mixture may not be as concerning adjacent ecosystems, but remains contaminant 60 years after ceased.

Caddisfly emergence is substantially affected by the combined exposure of titanium dioxide nanoparticles, natural organic matter and UV irradiation

Nanoparticles serve various industrial and domestic purposes which is reflected in their steadily increasing production ultimate release into the environment. Titanium dioxide nanoparticles pose due to high volume photoactive properties a potential environmental risk. Here we assessed impact combination with UV natural organic matter (NOM) at field relevant intensities on emergence dynamics quality of aquatic insect Chaetopteryx villosa (Insecta: Trichoptera) employing factorial test design. While alone TiO2 or NOM reduced by 50 %, all three factors (i.e., x NOM) caused an even stronger effect reduction 70 %). Following similar pattern, time until % larvae emerged was, depending treatment, delayed least 5.9 up 16.4 days. In contrast, nutritious adult C. villosa, characterized terms energy reserves fatty acid profiles, was hardly affected. Nonetheless, substantial same magnitude as reported for highly toxic chemicals, such insecticides. Consequently, (photoactive) may be concern, particularly under joint exposure further NOM). Moreover, light central ecological role insects interface between terrestrial ecosystems, present study points towards far-reaching consequences riparian food web productivity this meta-ecosystem.

Integrating the Bright and Dark Sides of Aquatic Resource Subsidies—A Synthesis

Ecology Letters, Год журнала: 2025, Номер 28(4)

Опубликована: Апрель 1, 2025

ABSTRACT Aquatic and terrestrial ecosystems are linked through the reciprocal exchange of materials organisms. Aquatic‐to‐terrestrial subsidies relatively small in most ecosystems, but they can provide high contents limiting resources that increase consumer fitness ecosystem production. However, also may carry significant contaminant loads, particularly anthropogenically impacted watersheds. Global change processes, including land use change, climate biodiversity declines, altering quantity quality aquatic subsidies, potentially shifting balance costs benefits for consumers. Many global processes interact impact both bright dark sides simultaneously, highlighting need future integrative research bridges as well disciplinary boundaries. We identify key priorities, increased quantification spatiotemporal variability across a range greater understanding landscape‐scale extent subsidy impacts deeper exploration relative

Selenium Differentially Influences Methylmercury Retention across Mayfly Life Stages

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Though high mercury and selenium concentrations are individually toxic to organisms, there is a hypothesized antagonistic relationship. This potential mercury-selenium interaction under-studied in aquatic macroinvertebrates, particularly relation complex life histories. We examined the proposed effect of on methylmercury accumulation between four stages for parthenogenetic mayfly (Neocloeon triangulifer). exposed diatoms elevated fed them mayflies aqueous selenomethionine. found some support antagonism hypothesis, but it was context-specific. Selenium reduced not low environments. terrestrial adult had higher compared larval stages, cumulative history transfer factor (LHTF; ratio imago late instar larvae) differed by treatment. LHTF constant all exposure levels at dietary (selenium impacts uptake loss) increased with exposures only), suggesting synergistic enhancement MeHg Se levels. These results suggest that animals eating insects than those feeding across levels, interference only present
