Fungal composition on leaves explains pollutant-mediated indirect effects on amphipod feeding.
TLDR
Effects of a fungicide on the conditioning process of leaf material by means of food-choice experiments using Gammarus fossarum seems to be a suitable indicator for alterations in leaf associated microbial communities, especially fungal species composition, caused by chemical stressors. Expand
Effects of subchronic fungicide exposure on the energy processing of Gammarus fossarum (Crustacea; Amphipoda).
TLDR
Direct ecotoxicological implications of tebuconazole, a frequently used triazole fungicide, on the leaf-shredding amphipod Gammarus fossarum were assessed and feeding rate, a sublethal endpoint, was significantly reduced. Expand
Effects of fungicides on decomposer communities and litter decomposition in vineyard streams.
TLDR
The results suggest that fungicides can affect LD under field conditions and that the structure of microbial and shredder communities as well as fungal biomass changed along the fungicide toxicity gradient. Expand
Ecotoxicological impact of the fungicide tebuconazole on an aquatic decomposer-detritivore system.
TLDR
Results suggest that tebuconazole affects both components of the investigated decomposer-detritivore system, however, adverse effects on the level of detritivores cannot be explicitly attributed to direct or indirect pathways. Expand
The functional and physiological status of Gammarus fossarum (Crustacea; Amphipoda) exposed to secondary treated wastewater.
TLDR
High proportions of wastewater in the stream flow may affect both the breakdown rates of leaf material and thus the availability of energy for the aquatic food web as well as the energy budget of G. fossarum. Expand
Does the current fungicide risk assessment provide sufficient protection for key drivers in aquatic ecosystem functioning?
TLDR
The results suggest that the European Union’s first-tier ERA provides sufficient protection for the tested fungicides, with the exception of tebuconazole and the mixture, while higher-tierERA does not provide an adequate level of protection for fungicides in general. Expand
Effects of peak exposure scenarios on Gammarus fossarum using field relevant pesticide mixtures.
TLDR
It is indicated that both pathways of exposure, namely via food or water, reduce gammarids' feeding rate synergistically, which suggests that both exposure pathways should be considered for compounds exhibiting a high Kow during the risk assessment of single substances and mixtures. Expand
The relative importance of diet-related and waterborne effects of copper for a leaf-shredding invertebrate.
TLDR
The results suggest that for adsorptive freshwater contaminants dietary uptake should be evaluated already during the registration process to safeguard the integrity of detritus-based ecosystems. Expand
Does the presence of titanium dioxide nanoparticles reduce copper toxicity? A factorial approach with the benthic amphipod Gammarus fossarum.
TLDR
Nano-TiO2 may be applicable as Cu-remediation agent, while its potential long-term effects need further attention. Expand
Fungicides: An Overlooked Pesticide Class?
TLDR
It is shown that fungicides occur widely in aquatic systems, that the accuracy of predicted environmental concentrations is debatable, and that fungicide exposure can be effectively mitigated, andThat fungicides can be highly toxic to a broad range of organisms and can pose a risk to aquatic biota.
