Hypothesis
How does the presence of the snail Bellamya purificata affect the bacterial, fungal, and protist communities in sediment?
Conclusion
The presence of Bellamya purificata significantly enhances the diversity of fungal communities while reducing the diversity of protist communities in sediment.
Supporting Evidence
- B. purificata significantly enhanced the diversity and evenness of the fungal community.
- B. purificata decreased the diversity and richness of the protist community.
- The presence of B. purificata altered the composition and relative abundance of dominant phyla in microbial communities.
- B. purificata expanded the habitat niche breadth for sediment bacteria and protists.
- B. purificata shifted the fungal community assembly from stochastic to deterministic processes.
Takeaway
Snails can change the types of tiny living things in the mud, helping some grow more and others less.
Methodology
The study used high-throughput sequencing technology to analyze microbial communities in sediment with and without the presence of B. purificata over a 90-day experiment.
Limitations
The study primarily focused on a single species of snail and its effects, which may not be generalizable to other benthic organisms.
