“…A lower mean annual abundance of 533–729 ind. cm−3 was found in sandy coastal sediments of the Bay of Biscay ( Fernandez‐Leborans & Novillo, 1993), probably due to the coarser sediments and lower organic input.…”

“…Fenchel (1967) concluded that HF and amoebae were much less important than ciliates but was aware that his methodology was most suitable for the counting of ciliates. Fernandez-Leborans & Novillo (1993) found that in sandy sediments of the Bay of Biscay, biomass © 2000 Blackwell Science Ltd, Freshwater Biology, 45, 147 -167 was dominated by ciliates at two of the three stations investigated, and by amoebae at the third station. Finlay et al (1988) estimated the biomass of benthic and pelagic heterotrophic protists in a hypertrophic freshwater pond.…”

“…A number of studies were aimed at the overall structure of either the protozooplankton or the micro-and nanozoobenthos, usually identifying either ciliates or flagellates as the dominant groups (e.g. Smetacek, 1981;Fernandez-Leborans & Novillo, 1993;Mathes & Arndt, 1994;Epstein, 1997). Comparisons between protozooplankton and benthic protistan communities were rarely presented (Bark, 1981;Finlay et al, 1988;Arndt et al, 2000).…”

Benthic–pelagic coupling: a comparison of the community structure of benthic and planktonic heterotrophic protists in shallow inlets of the southern Baltic

et al. 2000

1. The taxonomic composition, abundance and biomass of heterotrophic protists (ciliates, heterotrophic flagellates (HF), rhizopods and actinopods) in the sediment and water column of shallow inlets of the Southern Baltic was studied under a variety of environmental conditions during 1996–1997. A shallow, highly eutrophic station and a deeper, less eutrophic station were compared.  2. Community biomass ranged from 0.12 to 0.34 μg C cm−3 in the water column and from 1.5 to 105 μg C cm−3 in the sediment. Heterotrophic protists dominated zooplankton biomass at both stations (73% and 84% mean contribution), while they were of minor importance within the zoobenthos. Expressed per unit area, benthic biomass contributed a significant part (44% and 49%) to the total heterotrophic protistan community at both stations.  3. Although the methodology for counting ciliates and HF was focussed on a high taxonomic resolution, the results reveal some general trends in the distribution of heterotrophic protists: protozooplankton biomass was dominated by flagellates (80% mean biomass contribution) at the shallow station and by ciliates (73% mean biomass contribution) at the deep station. In the benthos at both stations, ciliates were the dominant protozoans, followed by the hitherto little‐studied rhizopods (25% and 35% mean biomass contribution) and flagellates.  4. The degree of benthic–pelagic coupling differed between taxonomic groups. Benthic and pelagic communities of ciliates showed little taxonomic overlap. In contrast, many heterotrophic flagellate species were found both in the benthos and in the pelagic. These benthic–pelagic species contributed significantly to the biomass of HF in the water column. The planktonic rhizopod community consisted of a subset of those species found in the benthos.  5. The abundance of benthic and pelagic protists was positively correlated at the shallow station, but taxonomic data indicate that the direct exchange between benthic and pelagic communities was only partly responsible.

“…The most frequently occurring species (at more than 30% of stations) were Salpingoeca rutt neri (Bourrelly, 1953) Bourrelly, 1968 (22 stations), Paraphysomonas sp. (17), Cafeteria roenbergensis Fenchel and Patterson, 1988 (16), Goniomonas amphinema Larsen and Patterson, 1990 (13), G. paci fica Larsen and Patterson, 1990 (8), and Massisteria marina Larsen and Patterson, 1990 (7). Fourteen spe cies (more than 40% of the species richness) were only found at one of the stations, suggesting a high degree of heterogeneity of the heterotrophic flagellate com munity.…”

“…Despite the recent studies [10,11,17,19,21,24,26,29,35], not much is known to date about the diver sity of protozoan communities (except foraminifera) of the sublittoral and deep water zones of the World Ocean [22]. At the same time, heterotrophic protists (particularly flagellates) are the most important con sumers of bacteria (including blue green algae), and microalgae in different aquatic ecosystems; they play a tremendous role in nutrient remineralization and car bon transfer to higher links of microbial loops in both pelagic and benthic habitats [20].…”

Free-living heterotrophic flagellates of the sublittoral and bathyal zones of the Kara Sea

The first data are presented on the species diversity and community structure of deep sea benthic heterotrophic flagellates in the Arctic (the Kara Sea). Thirty three species and forms of heterotrophic flagel lates were found, with kinetoplastids, stramenopiles, apusomonadids, and choanoflagellates being predomi nant. The species diversity of the studied region was characterized by a high beta diversity and a low alpha diversity, which is indicative of a substantially higher potential species richness of flagellates in the Kara Sea. The total number of species of flagellates decreased with increasing depth (from 15 to 554 m); peculiar fea tures of the species composition of deep sea flagellates were not revealed. However, the flagellate communi ties within two different biotopes (the upper layer of the bottom sediments and the loose, flocculent layer on the surface of sediments together with near bottom suspended matter) had similar taxonomic and trophic structures, but differed in the ratio of species with different feeding strategies. Attached or free swimming flagellates were predominant in the loose surfacelayer, whereas rapidly gliding species that are able to actively search for and capture food predominated in the bottom sediments.
