5 | Conclusion
We collected zooplankton community samples from the coral reef of an
oceanic island and performed metatranscriptome analyses. We found higher
similarity of OTU compositions in smaller- and lower similarity in
larger-size zooplankton community samples. Daytime and nighttime samples
were mixed in smaller- but separated in larger samples in nMDS analyses.
Furthermore, the effective number of communities increased toward
larger- and decreased toward smaller-size community samples. These
results indicated a shift in the role of dispersal through size. We
argue that metatranscriptomics is a promising platform for future
large-scale monitoring and detection of temporal and spatial
compositional changes.
