Host Dependence of Zooplankton-Associated Microbes and Their Ecological Implications in Freshwater Lakes

Zooplankton is colonized by quite different microbes compared with free-living and particle-associated bacteria, serving as a non-negligible niche of bacteria in aquatic ecosystems. Yet detailed analysis of these bacterial groups is still less known, especially in freshwater lakes. To widen our know...
