Abundant and Rare Microbial Communities Respectively Contribute to an Aquaculture Pond Ecosystem

Unraveling the assembly mechanism is a core research topic of microbial ecology. Abundant and rare communities are crucial for diversity, function host health in given ecosystem, but few studies focused on their strategies. Here, we explored diversity abundant water, shrimp intestine sediment habitats cultural ponds. Our results found that numbers operational taxonomic units (OTUs) (6,003, 4,566 8,237 OTUs sediment) was dozens times more than ones (only 199, 157 122 sediment). The community taxa markedly different, as well composition. Despite different similar abundance-occupancy relationship biogeographic patterns between were observed, with much stronger obvious distance-decay relationships community. Furthermore, stochastic processes dominated assemblies both taxa, deterministic process contributed variation to taxa. All findings advance our understanding strategies prompt contributions aquatic ecosystems, which will improve aquaculture management strategy.
