Abstract

Terrestrial originated suspended sediments from the Yellow River are crucial to understand the sources of the suspended sediment and ecological processes in estuary. This study integrated physicochemical indices, stable isotopes and microbial communities to trace the origin of the suspended sediment, and investigated the importance of ecological processes in community assembly via the null model and neutral community model. Global data revealed that the dissolved and particle ratios of carbon and nitrogen obviously decreased from the headstream to the estuary. A significant positive correlation was detected between δ15N and δ13C from Henan Province to offshore. Notable differences in bacterial community composition were found between Henan Province and offshore in dry season, whereas nearly no remarkable changes were detected throughout the entire YR basin in wet season. Multiple lines of evidence from physicochemical analysis, stable isotopic and genetic tracing revealed the possibility that the terrestriall
