Allochthonous and autochthonous particulate organic matter in floodplains of the River Danube: the importance of hydrological connectivity

摘要

1. The elemental composition, the proportion of living organic carbon and the carbon stable isotope signatures of particulate organic matter (POM) were determined in a large river floodplain system in order to elucidate the major carbon sources in relation to the hydrological conditions over a 13-month period.
