“…For instance, the changes in planktonic ciliate diversity from shallow to deep waters and from inshore to offshore on the continental shelf are significantly associated with increasing salinity (Grattepanche et al ). Nitrite and nitrate nitrogen (NO x ‐N), an important nutrient for autotrophs such as diatoms, has been associated with the temporal variability of eukaryotic community composition (Wang et al , ; Xue et al ). In the present study, NO x ‐N was associated with variations in community composition for all three protist groups, even the primarily heterotrophic ciliates.…”

The relative importance of different ecological processes that shape community structure is a central but poorly understood topic in protist ecology. This study used an 18S rRNA gene sequencing approach to examine the relative contributions of environmental selective (environmental filtering) and neutral processes (dispersal and ecological drift) in the community assembly of three diverse protist groups (Bacillariophyta, Cercozoa, and Ciliophora) from intertidal sediment samples spanning a geographical distance up to 12,000 km. All three protist communities exhibited similar and distinct biogeographical patterns, and followed strong distance-decay relationships at continental scale (ca. 12,000 km), regional scale (ca. 1500 km), and local scale (ca. 50 km). Network analysis showed that temperature, salinity, nitrite and nitrate nitrogen, total nitrogen, and 0.1-0.25 mm grain size together associated with 60.8%, 55.5%, and 50.0% of the OTUs, which represented 68.1%, 58.5%, and 59.2% of sequence abundances for Bacillariophyta, Cercozoa, and Ciliophora co-occurrence networks, respectively, indicating that these environmental variables played the central roles in influencing community composition. On the other hand, a neutral community model explained 73.6%, 64.2%, and 70.2% of community variation for Bacillariophyta, Cercozoa, and Ciliophora, respectively. More importantly, variation partitioning and partial Mantel tests showed that environmental selection exhibited a slightly greater influence on Ciliophora compared to spatial factors, but both components were roughly equivalent in Bacillariophyta and Cercozoa communities. Taken together, these results demonstrate that both environmental selection and neutral processes play important roles in creating the biogeographical patterns of protist communities in intertidal sandy beach ecosystems.

As an important component of microzooplankton, ciliates play a key role in matter cycling and energy flow in marine planktonic ecosystems. Studies of planktonic ciliate have been extensive in the South China Sea (SCS) over the last 20 years. Here, we summarize the recent progress on the diversity and distribution of this group in the SCS. This includes that in: (1) the waters covering the intertidal zone of the northern SCS, most studies have focused on taxonomy, with 71 species collected, identified, and described (with ~ 40% new species); (2) neritic waters distribution patterns have been examined at a regional scale, with ciliates displaying significant spatial variations and seasonal dynamics; (3) in oceanic waters, there has been a focus on ciliate distribution in north, centre, and south regions, where mesoscale physical processes play roles in controlling distributions, and noticeable vertical variations occur. More generally, some studies examine the influences of environment variables on ciliates, and indicate that chlorophyll a concentration is commonly positively correlated with ciliates abundance. In addition, some significant findings are summarized, the limitations of past studies are considered, and recommendations are made for future work on planktonic ciliates in SCS.

“…E-mail: huanghh@scsfri.ac.cn environments and phytoplankton community (Li et al, 2012). The drastic changes in the environmental and biological factors would lead to a great alteration of the ciliates abundance and species composition (Wang et al, 2013;de Cao et al, 2013). Many investigations have thus been conducted on the ciliates abundance and species diversity in the SCS (Liu et al, , 2013Gomez, 2007).…”

Ciliates are very important components in most marine ecosystem. They are trophic link between the microbial food web and grazing food chain. In this study, ciliates were collected from 11 sites in the southern South China Sea (SCS) during August 25 to September 28, 2011. Their composition and distribution at the surface and 75 m deep depth of the ocean were studied. A total of 30 species belonging to 22 genera were identified, and 22 species of 15 genera were Tintinnids. Eutintinnus fraknoii and E. stramentus were the most common species. The other dominants were strombidiids ciliates including Strombidium conicum and S. globosaneum, which were followed by the tide form, Mesodinium pulex. Ciliates abundance ranged from 46 ind L −1 to 368 ind L −1 in the open sites, 46-368 ind L −1 at surface and 73-198 ind L −1 at 75 m deep layer. In the Yongshu reef, ciliates abundance ranged from 167 ind L −1 to 365 ind L −1 in the water column, similar to that in Sanya coral reef waters. Ciliates composition showed obvious difference between surface and 75 m deep layer at station S2 (P < 0.05), while no similar result was observed at other sites. At 75 m deep layer, salinity was negatively related to mixed layer depth (P < 0.05), but positively to chlorophyll a concentration (P < 0.05), indicating that the change of vertical mixing in water column influenced vertical distribution of ciliates in the southern SCS.
