Full-text available
Agricultural land covers approximately 40% of Earth’s land surface and affects hydromorphological, biogeochemical and ecological characteristics of fluvial networks. In the northern temperate region, agriculture also strongly affects the amount and molecular composition of dissolved organic matter (DOM), which constitutes the main vector of carbon...
Conference Paper
Tree trunks that naturally fall into rivers or are introduced through river restoration have been shown to significantly change the flow and sediment characteristics in the surrounding areas of the river bed. Hence, we hypothesized that even the presence of a single wood log may exert significant and reproducible effects on invertebrate colonizatio...
Article
Full-text available
The ecological status of subtropical floodplain lakes is threatened by eutrophication, which can shift lakes from a clear, macrophyte-dominated equilibrium state to a turbid, phytoplankton-dominated state. Such a shift is reflected in their macroinvertebrate assemblages, which may serve as good indicators of long-term changes in such lake ecosystem...
