Fungicides are indispensable to global food security and their use is forecasted intensify. can reach aquatic ecosystems occur in surface water bodies agricultural catchments throughout the entire growing season due frequent, prophylactic application. However, comparison herbicides insecticides, exposure effects of fungicides have received less attention. We provide an overview risk covering fungicide (i.e., environmental fate, modeling, mitigation measures) as well direct indirect on...
Abstract Leaf litter breakdown is a fundamental process in aquatic ecosystems that realized by microbial decomposers and invertebrate detritivores. Although this may be adversely affected fungicides, among other factors, no test design exists to assess combined effects on such decomposer–detritivore systems. Hence, the present study assessed of model fungicide tebuconazole (65 µg/L) conditioning leaf material (by characterizing associated community) as well (i.e., direct toxicity food...
The level of protection provided by the present environmental risk assessment (ERA) fungicides in European Union for fungi is unknown. Therefore, we assessed structural and functional implications five with different modes action (azoxystrobin, carbendazim, cyprodinil, quinoxyfen, tebuconazole) individually mixture on communities aquatic hyphomycetes. This a polyphyletic group containing key drivers breakdown leaf litter, governing both microbial decomposition palatability leaves...
Abstract Background Examining the effects of pesticides is difficult in regions such as Western Europe because relatively ubiquitous use agrochemicals and lack unaffected areas. To study a wide gradient agrochemical stress, we conducted Central Romania, where traditional agriculture, which assumed to less agrochemicals, exists adjacent intensive agriculture. We investigated potential land related stressors including on aquatic–terrestrial predator–prey relationships using stable isotope...
Practical, legal, and ethical reasons necessitate the development of methods to replace animal experiments. Computational techniques acquire information that traditionally relied on testing are considered a crucial pillar among these so-called new approach methodologies. In this light, we recently introduced Bio-QSAR concept for multispecies aquatic toxicity regression tasks. These machine learning models, trained both chemical biological information, capable cross-chemical cross-species...
Summary Molecular genetic methods continuously uncover cryptic lineages harboured by various species. However, from an applied perspective, it remains unclear whether and to which extent such a diversity affects biological traits (e.g. ecological, behavioural physiological characteristics) environmental management. We assessed potential deviations regarding the trait ‘environmental stress tolerance’ using individuals five field populations of each two (called A B ) comprised under nominal...
We reconstructed the first long-term (1968-2015) spatiotemporal trends of perfluoroalkyl substances (PFAS) using archived body feathers white-tailed eagles (Haliaeetus albicilla) from West Greenland (n = 31), Norwegian 66), and Central Swedish Baltic coasts 50). observed significant temporal perfluorooctane sulfonamide (FOSA), sulfonate (PFOS), carboxylates (∑PFCAs) in all three subpopulations. Concentrations FOSA PFOS had started decreasing significantly since mid-1990s to 2000...
Aquatic micropollutants can be transported to terrestrial systems and their consumers by emergent aquatic insects. However, micropollutants, such as metals, may also affect the flux of physiologically important polyunsaturated fatty acids (PUFAs). As certain PUFAs have been linked physiological fitness breeding success consumers, reduced fluxes from could populations food webs. We chronically exposed larvae insect Chironomus riparius a range environmentally relevant sediment contents cadmium...

Abstract Ecosystem functions in streams (e.g., microbially mediated leaf litter breakdown) are threatened globally by the predicted agricultural intensification and its expansion into pristine areas, which is associated with increasing use of fertilizers pesticides. However, ecological consequences may depend on disturbance history microbial communities. To test this, we assessed effects fungicides nutrients (four levels each) structural functional resilience leaf‐associated communities...
Abstract Fungi produce a variety of extracellular enzymes, making recalcitrant substrates bioavailable. Thus, fungi are central for the decomposition dead organic matter such as leaf litter. Despite their ecological importance, our understanding relationships between fungal species diversity and ecosystem functioning is limited, especially with regard to aquatic habitats. Moreover, interactions other groups microorganisms bacteria rarely investigated. This lack information may be attributed...
Aquatic hyphomycetes (AHs), a group of saprotrophic fungi adapted to submerged leaf litter, play key functional roles in stream ecosystems as decomposers and food source for higher trophic levels. Fungicides, controlling fungal pathogens, target evolutionary conserved molecular processes contaminate streams via their use agricultural urban landscapes. Thus fungicides pose risk AHs the functions they provide. To investigate impacts fungicide exposure on composition functioning AH communities,...
Neonicotinoids are increasingly applied on trees as protection measure against insect pests. Consequently, neonicotinoids inevitably transferred into aquatic environments either via spray drift or surface runoff (due to neonicotinoids' systemic nature) senescent leaves. There particularly leaf-shredding invertebrates may be exposed through both the water phase and consumption of contaminated In 7 day bioassays (n = 30), we examined ecotoxicological differences between these two exposure...
Summary The application of fungicides is considered an indispensable measure to secure crop production. These substances, however, may unintentionally enter surface waters via run‐off, potentially affecting the microbial community. To assess such risks adequately, authorities recently called for suitable test designs involving relevant aquatic micro‐organisms. We assessed structural and functional responses leaf‐associated communities, which play a key role in breakdown allochthonous leaf...
Abstract Nanoparticle contaminants enter aquatic ecosystems and are transported along the stream network. Here, we demonstrate a novel pathway for return of nanoparticles from to terrestrial via cross-boundary subsidies. During their emergence, trichopteran caddisflies carried titanium dioxide gold into life stages. Moreover, emergence was delayed by ≤30 days, energy reserves were depleted ≤25%. Based on worst case estimates, it is suggested that predators, such as bats feeding prey, may...
Systemic neonicotinoid insecticides are increasingly used as a crop protection measure to suppress insect pests on trees. However, senescent foliage falling from treated trees represents rarely studied pathway through which neonicotinoids may enter nontarget environments, e.g., surface waters. To estimate risk posed by this pathway, residues were analyzed in black alder with one of three (imidacloprid, thiacloprid, or acetamiprid) at five concentrations, each ranging 0.0375–9.6 g active...
