“…Additionally, marine fungi play fundamental roles in the ecosystem as saprotrophs and are known for their significant contributions to decomposition cycles (Ainsworth et al, 2017), which in turn provide food for detritivores (Jones et al, 2015). More importantly, the establishment of marine microeukaryote community structure can also be potentially used as bioindicators of environmental change or pollution (Xu et al, 2015). Characterization of eukaryote communities from ARMS will thus have important implications for understanding reef ecosystem health and species trophic functions, since these non‐metazoans are involved in food production and detrital nutrient cycling that support significant reef organismal biomass (Rogers et al, 2018).…”

Coral reefs are among the richest marine ecosystems on Earth, but there remains much diversity hidden within cavities of complex reef structures awaiting discovery. While the abundance of corals and other macroinvertebrates are known to influence the diversity of other reef‐associated organisms, much remains unknown on the drivers of cryptobenthic diversity. A combination of standardized sampling with 12 units of the Autonomous Reef Monitoring Structure (ARMS) and high‐throughput sequencing was utilized to uncover reef cryptobiome diversity across the equatorial reefs in Singapore. DNA barcoding and metabarcoding of mitochondrial cytochrome c oxidase subunit I, nuclear 18S and bacterial 16S rRNA genes revealed the taxonomic composition of the reef cryptobiome, comprising 15,356 microbial ASVs from over 50 bacterial phyla, and 971 MOTUs across 15 metazoan and 19 non‐metazoan eukaryote phyla. Environmental factors across different sites were tested for relationships with ARMS diversity. Differences among reefs in diversity patterns of metazoans and other eukaryotes, but not microbial communities, were associated with biotic (coral cover) and abiotic (distance, temperature and sediment) environmental variables. In particular, ARMS deployed at reefs with higher coral cover had greater metazoan diversity and encrusting plate cover, with larger‐sized non‐coral invertebrates influencing spatial patterns among sites. Our study showed that DNA barcoding and metabarcoding of ARMS constitute a valuable tool for quantifying cryptobenthic diversity patterns and can provide critical information for the effective management of coral reef ecosystems.

“…Protozoa respond rapidly to changes of environmental conditions, and are easily collected for spatial/temporal comparisons, and thus have been widely used as a bioindicator of water quality in aquatic ecosystems (Morin et al ., 2010; Xu et al ., 2014c). Based on our previous studies, biofilm-dwelling protozoa represent a feasible indicator of water quality status in marine ecosystems (Xu et al ., 2014a, b, c, 2015a, b, c, d).…”

As an inherent function of a community, body-size spectrum has been increasingly used as a useful indicator in global ecological research. The colonization dynamics of biofilm-dwelling protozoa with regard to body-size spectrum were studied based on a 1-month baseline survey in coastal waters of the Yellow Sea, northern China. Samples were collected at time intervals of 1, 3, 7, 10, 14, 21 and 28 days from depths of 1 and 3 m. A total of seven body-size ranks were identified based on a trait hierarchy. The individual abundance of the protozoa at each body-size rank was well fitted to the logistic model equation. The body-size spectra showed a clear shift in probability density during the colonization period at both depths. The multivariate approach demonstrated that the temporal dynamics in body-size spectra of the protozoa may be divided into initial (1 day), transitional (3–7 days) and stable (10–28 days) stages during the colonization period. These results provide useful information for ecological research and monitoring programmes using biofilm-dwelling protozoa in marine ecosystems.
