“…nov. with similar taxa (Table 2) Considering its body size and shape, moniliform macronucleus and basic ciliary pattern, Anteholosticha marimonilata should be compared with five similar congeners, i.e. A. monilata, A. xanthichroma, A. sigmoidea, A. distyla and A. australis (Augustin & Foissner, 1992;Blatterer & Foissner, 1988;Buitkamp, 1977;Foissner, 1982Foissner, , 1984Foissner & Didier, 1981;Song & Wilbert, 1989;Wirnsberger & Foissner, 1987). Among these, A. monilata is most similar to the novel species.…”

“…Anteholosticha australis can be distinguished from A. marimonilata in having fewer transverse cirri (3-6 compared with 10-13), ellipsoidal cortical granules, which can be impregnated heavily with protargol, and ejected (vs spherical cortical granules that cannot be ejected) and its terrestrial (vs marine) habitat (Blatterer & Foissner, 1988; Table 2). …”

“…To date, about 38 species of the genus Anteholosticha have been described (Alekperov & Asadullayeva, 1999;Berger, 2006Berger, , 2008Blatterer & Foissner, 1988;Borror & Wicklow, 1983;Buitkamp, 1977;Dragesco, 1966Dragesco, , 1970Dragesco & Dragesco-Kernéis, 1986;Foissner, 1982Foissner, , 1987Foissner, , 2000Foissner et al, 2002;Gellért, 1956;Grolière, 1975;Hemberger, 1985;Kahl, 1928Kahl, , 1932Von Mereschkowsky, 1877;Song & Wilbert, 1997;Wirnsberger & Foissner, 1987). Of these, only six species have been described in detail in terms of their morphogenetic processes and likewise SSU rRNA gene sequence data are also only available for six species (Berger, 2006;Chen et al, 2010).…”

The morphology, morphogenesis and molecular phylogeny of the marine ciliated protozoan Anteholosticha marimonilata spec. nov., isolated from mollusc-farming waters of the Yellow Sea, Qingdao, PR China, were investigated using microscopic observations of live and protargolimpregnated specimens and by small subunit rRNA gene sequence analysis. The novel species could be distinguished by the following features: an elongated elliptical body, in vivo size 80-160 mm ¾ 30-50 mm; an adoral zone consisting of about 36 membranelles; three frontal, one parabuccal, one buccal, two frontoterminal and usually two pretransverse ventral cirri; 10-13 transverse cirri; a midventral complex composed of 12-17 pairs of cirri only, terminating in posterior 1/5; four or five dorsal kineties; two types of colourless cortical granules; four to nine moniliform macronuclear nodules and one to three micronuclei, and a contractile vacuole positioned at mid-body. Hitherto, the ontogenesis of the genus Anteholosticha has been regarded as rather diverse, which was confirmed by the morphogenetic processes of this novel species. The most noteworthy feature of A. marimonilata was that the proter retained almost the entire parental adoral zone except for a few proximal membranelles that were renewed in situ. The SSU rRNA gene sequence information clearly discriminated this isolate from its congeners. Molecular phylogenetic analyses demonstrated, with high statistical support, that A. marimonilata branched as a sister lineage to the Nothoholosticha-Pseudokeronopsis clade and hence belongs to the core part of the order Urostylida.

“…Most species seem to be truly planktonic and free swimming, and previous references of tintinnids attached to substrates are rare. Blatterer and Foissner (1990) described an attached freshwater tintinnid, and there have been several reports of Tintinnidium inquilinum or Tintinnus (Eutintinnus) inquilinus, an attached marine tintinnid (Kofoid andCampbell 1929, 1939). There have also been several published observations of tintinnids found in samples that have diatoms attached to their loricae (Kofoid and Campbell 1929;Taylor 1982;Sassi et al 1999).…”

Attachment to suspended particles may improve foraging and reduce predation risk for tintinnid ciliates

We describe a new behavior of planktonic ciliates. The field-collected tintinnid Eutintinnus inquilinus attached with its lorica to a range of surfaces, including particulate aggregates. Most tintinnids remained attached with the aboral end of their lorica when well fed. On starvation, many tintinnids detached and resumed a free-swimming life. We hypothesize that the adhesive property of the lorica has evolved as an adaptation to attach to suspended aggregates or other seston particles. Attached E. inquilinus have a feeding rate that is 80% higher than freeswimming individuals because of the change in the fluid dynamics of the feeding current for attached E. inquilinus, which leads to steeper velocity gradients and higher flow rates close to the lorica. This mechanism will also operate for swimming suspension feeders attached to smaller particles that significantly increase the hydrodynamic drag. Selection for traits that enhance the velocity gradients in feeding currents of small plankton may be common and may partly shape behavioral patterns and functional morphology. When exposed to the calanoid copepod Acartia clausi, populations of E. inquilinus were less susceptible to predation than another Eutintinnus species of similar morphology but that were entirely free swimming.

“…More recently, specific attention has also been addressed to the description of ciliates belonging to the planktonic and benthonic microcommunities of lakes (Bark, 1981;Madoni, 1989Madoni, , 1990Beaver & Crisman, 1990;Laybourn-Pany et al, 1990a), reservoirs (Simek et al, 1990), and rivers (Baldock & Sleigh, 1988;Grabacka 1988;Carlough & Meyer, 1989;Blatterer & Foissner, 1990;Grolière et al, 1990;Finlay et al, 1993). As far as the Italian lakes are concerned, only the ciliate communities of Lake Maggiore, Lake Orta (Ruggiu, 1965(Ruggiu, , 1969, and of an artificial lake in the Tusco-Emilian Apennines (Madoni, 1989) have been studied.…”

The ciliate communities, living in different habitats of Lake Massaciuccoli and its marshland, were studied from June 1992 to July 1993. Ninety-three species were identified and their relative abundance and biomasses evaluated, both at the surface and at the bottom levels of four different stations (placed in the lake close to the shore of Piaggetta, Burlamacca canal, Collettore canal, and in one small shallow pond called Chiaro). The most interesting results are: (a) the great biodiversity of the ciliate communities found in Lake Massaciuccoli likely depends upon the wide range of different microhabitats available for these communities and present in the four stations chosen; (b) the communities of the Piaggetta and Burlamacca stations are similar to each other, mainly characterized in their seasonal dynamics at the surface level (open water); (c) the communities of the Collettore and the Chiaro stations are typical of shallow waters, characterized by very large amounts of organic debris on the bottom, as shown by the rich populations of filter-feeders and thigmotactic species which, in turn, constitute a good pabulum for the carnivorous species; (d) the major peaks of specimens density and biomass values were found during autumn 1992 and in early spring 1993.
