“…Amphorellopsis tetragona (Jörgensen, 1924) Kofoid et Campbell, 1929 (Fig. 1A) has not been previously noted in the Barents Sea and adjacent waters (Meunier, 1910; Olga Chovgan Rossolimo, 1927;Burkovsky et al, 1974;Burkovsky, 1976;Lifshits, 1977;Dolan et al, 2017).…”

“…Currently the total number of tintinnid species (suborder Tintinnina Kofoid et Campbell, 1929) in the Barents Sea remains unknown. There are heterogeneity and inconsistency of taxonomy information in plankton records (Lifshits, 1978;Burkovsky, 1974;Dolan et al, 2017). The morphological variability of lorica complicates distinguishing between typical forms of tintinnids, varieties and different stages of life cycle (Rossolimo, 1927;Lifshits, 1977;Dolan et al, 2017).…”

“…It should be noted that both of the small species mentioned above, under sampled or missing from the net material, are very common forms and nearly ubiquitous in the world ocean. For example, S. faurei is found in systems from Antarctica to the South Pacific and the high Arctic (Dolan et al , , ). In sum, the whole water samples provided abundance estimates an order of magnitude greater than the estimates from 52 μ m net material and indicated an assemblage of species dominated by forms with small lorica diameters.…”

A note on the differences found between examining whole water vs. phytoplankton net (52 μm mesh) samples to characterize abundance and community composition of tintinnid ciliates (marine microzooplankton) AbstractMost tintinnid species have a shortest linear dimension < 50 μm. Hence, a priori, nets of mesh sizes ≥ 50 μm will likely under-sample most tintinnid species. However, studies often appear (23 since 2015) using sampling with nets of meshes sizes ≥ 50 μm, reporting both tintinnid concentrations, and community composition. How biased are results from using coarse mesh nets? We provide a comparison of whole water vs. net sampling based on fortuitous, that is, unplanned, parallel sampling. Pairs of samples from a standard monitoring station in the Bay of Villefranche (N.W. Mediterranean Sea) taken on 44 dates from 2013 to 2018 were compared. Tintinnids were enumerated in settled material from a water column sample, an integration of six discrete depth samples between 5 and 70 m, prepared for analysis of phytoplankton composition and in material from a plankton net (52 μm mesh) tow from 70 to 0 m, taken the same day. Despite the large confidence limits due to low raw cell counts from whole water samples, cell concentration estimates were about an order of magnitude higher than those from plankton net samples and frequently biomass estimates as well. Community composition also differed. The most common species in whole water samples were small (diameter ≤ 20 μm), and some common forms were absent, or nearly, from the net samples. We show that, while valuable for collecting larger and rarer species, coarse net samples do not yield robust estimations of overall concentrations, nor allow identification of the dominant tintinnid species.

“…The P. gigantea models showed a good fit for the North Atlantic locality data, in that they recovered the areas where the species has been detected, without predicting an area too broad to be credible; however, the North Pacific was not included in the model predictions. Additional locality data for P. gigantea compiled in a recent study (Dolan et al 2017) comprised 38 additional locality points for the species, and all were anticipated in our LPT model (significant p < 0.05). Few locality points for Z. pelagicum were available from outside the North Atlantic (N = 6), all from the North Pacific.…”

The biogeographic pattern of single‐celled eukaryotes (protists), including ciliates, is poorly understood. Most marine species are believed to have a relatively high dispersal potential, such that both globally distributed and geographically isolated taxa exist. Primary occurrence data for three large, easily identified ciliate species, Parafavella gigantea, Schmidingerella serrata, and Zoothamnium pelagicum, and environmental data drawn from the National Oceanic and Atmospheric Administration's World Ocean Atlas were used to estimate each species’ spatial and environmental distributions using Maxent v3.3.3k. The predictive power of the models was tested with a series of spatial stratification studies, which were evaluated using partial receiver operating characteristic (ROC) statistics. Differences between niches occupied by each taxon were evaluated using background similarity tests. All predictions showed significant ability to anticipate test points. The null hypotheses of niche similarity were rejected in all background similarity tests comparing the niches among the three species. This article provides the first quantitative assessment of environmental conditions associated with three species of ciliates and a first estimate of their spatial distributions in the North Atlantic, which can serve as a benchmark against which to document distributional shifts. These species follow consistent, predictable patterns related to climate and environmental biochemistry; the importance of climatic conditions as regards protist distributions is noteworthy considering the effects of global climate change.
