“…Planktonic ciliates, as an important component of microzooplankton, have been extensively investigated for their important ecological roles in the Pacific Arctic Region (e.g., Jiang et al, 2015 ; Dolan et al, 2016 , 2021 ; Li et al, 2016 ; Xu et al, 2018a , b ; Wang et al, 2019 , 2022b ; Wang C. F. et al, 2020 ). However, studies related to ciliate Pacification are still scant.…”

“…In the Pacific Arctic Region, Pacific-origin tintinnids were transported from the Bering Sea to the Arctic Ocean mainly in waters > 4 ° C ( Li et al, 2016 ; Wang et al, 2019 , 2022b ). For this reason, they probably could not survive in cold Arctic waters (<0 ° C).…”

“…The size-fractions were further clustered into small (10–20 μm), medium (20–30 μm), and large (>30 μm) ( Sohrin et al, 2010 ). Tintinnid taxa were identified to the species level according to the size and shape of loricae following Taniguchi (1976) , Davis (1977 , 1981) , Zhang et al (2012) , Dolan et al (2014 , 2017) , Li et al (2016) , and Wang et al (2019 , 2022a , b) . Because mechanical and chemical disturbance during collection and fixation can detach the tintinnid protoplasm from the loricae ( Paranjape and Gold, 1982 ; Alder, 1999 ), we included empty tintinnid loricae in cell counts.…”

Planktonic ciliates are an important component of microzooplankton, but there is limited understanding of their responses to changing environmental conditions in the Pacific Arctic Region. We investigated the variations of ciliate community structure and their relationships with environmental features in the Pacific Arctic Region in the summer of 2016 and 2019. The Pacific water was warmer and more saline in 2019 than in 2016. The abundance and biomass of total ciliate and aloricate ciliate were significantly higher in 2019 than those in 2016, while those of tintinnid were significantly lower. The dominant aloricate ciliate changed from large size-fraction (> 30 μm) in 2016 to small size-fraction (10–20 μm) in 2019. More tintinnid species belonging to cosmopolitan genera were found in 2019 than in 2016, and the distribution of tintinnid species (Codonellopsis frigida, Ptychocylis obtusa, and Salpingella sp.1) in 2019 expanded by 5.9, 5.2, and 8.8 degrees further north of where they occurred in 2016. The environmental variables that best-matched tintinnid distributions were temperature and salinity, while the best match for aloricate ciliate distributions was temperature. Therefore, the temperature might play a key role in ciliate distribution. These results provide basic data on the response of the planktonic ciliate community to hydrographic variations and implicate the potential response of microzooplankton to Pacification as rapid warming progresses in the Pacific Arctic Region.

“…Therefore, we conclude that the higher sea temperature in 2019 was due to warm advection from PIW, bringing heat to the Arctic Ocean. Planktonic ciliates, as an important component of microzooplankton, have been extensively investigated for their important ecological roles in the Pacific Arctic Region (e.g., Jiang et al, 2015;Dolan et al, 2016Dolan et al, , 2021Li et al, 2016;Xu et al, 2018a,b;Wang et al, 2019Wang et al, , 2022bWang C.
