“…This species was typically found at temperatures of 5-10 o C with salinities of 30-35 psu (OBIS, 2017). One of the East Sea indicator species (Kim et al, 2012), Epiplocyloides reticulata, was commonly found at OnSW and UpW stations but not at OSW station. The two water types UpW and OnSW shared about 36.0% similarity in their tintinnid assemblages but the dominant species of these two water types are different.…”

“…A SIMPER analysis showed a difference between the OSW and UpW tintinnid assemblages of about 78.1% and a smaller difference of 72.9% between the OSW and OnSW communities. At our station offshore FK001 (OSW), which was warm and oceanic, as much as 50% of the species were indicators for warm Kuroshio waters (Kim et al, 2012), including the two most abundant species, Salpingella acuminata and Xystonella treforti. In our samples, one species characteristic of cold oceanic water, Acanthostomella norvegica, (Pierce & Turner, 1993), was found primarily at OnSW stations (e.g.…”

Tintinnidsarean important protozoan group in the aquatic food web and had been widely studied in various waters. There are about 1000 known species in the world. However, there have beenvery few taxonomic studies in Vietnam and therefore the number of Tintinnid taxa and their distribution are poorly known. Thepresent study documents 65 tintinnids species belonging to 30 genera and 13 families in samples collected from Khanh Hoa - Binh Thuan waters in 2016 and 2017. There were 17 new taxa records for Vietnam protozoan fauna, raising the number of tintinnids recorded in Vietnam to 125 taxa. Tintinnid assemblages in Khanh Hoa-Binh Thuan waters shared about 17 species with Ha Long Bay, 32 species with Con Co island and 26 species with coastal waters of South Vietnam. Analysis of species diversity shows that the Shannon diversity index H' varied from 1.5 to 2.6. Distribution of species numbers and diversity in the Khanh Hoa - Binh Thuan waters revealed possible combined effects of hydrographical activities (e.g. upwelling), Mekong river influent (e.g. salinity), and food available on tintinnid communities.

“…However, studies of the relationship between the TWC and small 5 zooplankton such as copepods are very limited, especially concerning their spatial distribution. In the TWC, zooplankton biomass varies interdecadally (Hirota and Hasegawa, 1999;Kang et al, 2002;Chiba et al, 2005), and community structure varies seasonally in accordance with water temperature, and interannually with the thickness of the TWC (Chiba and Saino, 2003); however, the advection of small zooplankton and its implication for communities have been not discussed, except for studies on tintinnid distributions in the Tsushima Strait (Kim et al, 2012). 10 Zooplankton biomass is homogeneous in the CBTWC area, along the Japanese coastline (Hirota and Hasegawa, 1999), but from two previous studies, Iguchi and Tsujimoto (1997) and Iguchi et al (1999), it can be identified heterogeneity in zooplankton community structure during spring bloom period: warm-water species (Calanus sinicus, Corycaeus affinis, and Palacalanus pavrus) are dominant in Wakasa Bay, in the western part of the Japan Sea, while cold-water species (Pseudocalanus newmani, Metridia pacifica, and Oithona atlantica) are dominant in Toyama Bay, in the east.…”

Abstract. This study evaluates spatial variations in zooplankton community structure and potential controlling factors along 10 the Japanese coast under the influence of the coastal branch of the Tsushima Warm Current (CBTWC). Variations in the density of morphologically-identified zooplankton in the surface layer in May were investigated for a 15-year period. The density of zooplankton (individuals per cubic meter) varied between sampling stations, but there was no consistent west-east trend. Instead, there were different zooplankton community structures in the west and east, with that in Toyama Bay particularly distinct: Corycaeus affinis and Calanus sinicus were dominant in the west and Oithona atlantica was dominant in 15 Toyama Bay. Distance-based redundancy analysis (db-RDA) was used to characterize the variation in zooplankton community structure, and four axes (RD1-4) provided significant explanation. RD2-4 only explained <6.5% of variation in the zooplankton community and did not show significant spatial difference; however, RD1, which explained 84.6% of variation, did vary spatially. Positive and negative species scores on RD1 represent warm-and cold-water species, respectively, and their variation was mainly explained by water column mean temperature. Water column mean temperature is highly correlated 20 with mean and maximum salinity, and it is considered to vary spatially with the CBTWC. The CBTWC intrusion to cold Toyama Bay is weak and occasional due to the submarine canyon structure of the bay. Therefore, the varying bathymetric characteristics along the Japanese coast of the Japan Sea generate the spatial variation in zooplankton community structure, and dominance of warm-water species can be considered an indicator of the CBTWC.

“…Thus, planktonic ciliates may act as important trophic intermediates from the microbial loop to higher trophic levels in the sea. By virtue of their rapid response to environmental changes, planktonic ciliates may play a part in indicating the water quality in aquatic ecosystems (Xu et al 2008, Jiang et al 2012, Kim et al 2012.…”

“…So far there have been several studies on the spatial patterns of marine planktonic ciliates (Sanders 1987, Montagnes et al 1988, Zhang and Wang 2000, Kchaou et al 2009, Jiang et al 2011, Kim et al 2012. There is, however, limited information about marine ciliate communities in China, and relevant research in China has mostly been conducted in the Bohai and Yellow Seas (Song and Bradbury 1998, Zhang et al 2008, Jiang et al 2011, Yu et al 2011) and the South China Sea (Gómez 2007, Su et al 2007, Feng et al 2010, Liu et al 2010.…”

Surface water samples were collected from 19 sites in the northern Beibu Gulf in April 2011. Species composition and abundance of planktonic ciliates were investigated. They were combined with environmental data to obtain the spatial pattern of the ciliate community and its relationship with the environment. A total of 36 species belonging to 13 genera and 3 orders (Oligotrichida, Haptorida and Tintinnida) were identified, including 10 dominant species. All 19 samples were divided into three groups using cluster analysis and multidimensional scaling (MDS) on the basis of the ciliate species composition and abundance. Group 1 was the least abundant. The species of the order Oligotrichida dominated in Group 2. In contrast, Mesodinium species were of increased importance in Group 3. * Corresponding author e-mail: zhangwenjing@xmu.edu.cnRedundancy analysis (RDA) revealed that ciliate communities were more closely related to the level of nitrogen (total nitrogen, nitrate nitrogen, nitrite nitrogen) and phosphorus (total phosphorus, active phosphorus) rather than other variables. As the levels of nitrogen and phosphorus increased, communities dominated by species from the order Oligotrichida were replaced by those dominated by Mesodinium species.
