| 英文摘要 | In natural ecosystems, large amounts of epiphytic bacteria live on the surfaces of submerged plants or non biological substrates. Although it contributes greatly to host plant health or ecological functions in waters, little is known about the temporal dynamics and assembly mechanisms of epiphytic bacteria. To test whether host plant chemistry leads to divergent community dynamics, we investigated the fine scale temporal community successions of both epiphytic bacteria and the bacterioplankton of the surrounding water in two submerged plants and one non-biological artificial substance. We first observed differentiated epiphytic or surrounding water bacterial communities for different substrates in small spaces (approximately 1 m x 1 m). Selection played dominant roles in affecting the assembly of epiphytic bacteria in the high-phenolic plant Hydrilla verticillata, while for the artificial substance and the low-phenolic plant Vallisneria natans, drift and dispersal drove the assembly of both epiphytic bacteria and bacterioplankton. The higher selection may also contribute to higher turnover rates in both bacterioplankton and epiphytic communities of H. verticillata, with the latter changing drastically in approximately one week. Epiphytic bacteria in H. verticillata developed more complex networks with a higher proportion of positive links, suggesting that more intense interactions such as mutualism or facilitation may exist within epiphytic bacterial communities of the high-phenolic plant. Our results also implied that for the submerged macrophytes used in biological purification, the dynamics of epiphytic biofilm in the purification-related functional capacities might also be considered.
