A FIELD BASED EXPERIMENT ON THE RESPONSES OF DIFFERENT MICROBIAL COMMUNITIES AND RELATED ECOSYSTEM FUNCTIONS TO FUNGICIDES
In viticulture, fungicides are the predominant pesticide group and are known to affect stream microbial communities, particularly the hyphomycete fungi. These play a key role in the decomposition of allochthonous material. Previous studies showed that hyphomycete communities and its decomposition are altered along fungicide gradients. In this study, we focused on the community and ecosystem function responses to fungicides using three hyphomycete community treatments on leaves in ten streams in an intensive vinicultural region of South-West Germany. The first treatment represented an undisturbed control in a forested upstream area. The second treatment represented a viticulture treatment in the downstream vinicultural area. The third treatment represented a transplantation treatment where the leaves were colonised by hyphomycete communities in the forested upstream area and subsequently transplanted to the downstream vinicultural area. We analysed the community composition and microbial leaf decomposition of the three treatments at four different time points, capturing the time before, within and after fungicide application. We discuss the community and ecosystem function responses to fungicides and potential mechanisms.
