Local terrestrial landscape, aquatic conditions and dendritic distance shape bacterioplankton communities along a small hydrological network in the Colombian Amazon
Here, we explored the relative importance of terrestrial landscape composition, local aquatic conditions and dendritic distance in explaining the variation in aquatic bacterial communities along a small Amazonian hydrological network with terrestrial landscape heterogeneity. In general, our results stress the importance of the terrestrial surrounding landscape in the variation of the bacterioplankton community structure. This improves our understanding of the dynamics of freshwater bacterioplankton metacommunities, and provides clear links between freshwater and surrounding terrestrial environments, which should modify our approach to ecosystem conservation and biomonitoring strategies.
