    Notes: SYNOPSIS. The foraminiferal distribution in samples from the Western Pacific collected in the summer of 1956 is presented, particularly those of the islets comprising Eniwetok Atoll. Some information is based upon samples taken shortly after atomic tests had been conducted. The distribution of foraminifera from northern islets where the tests were conducted is compared with that from the southern islets of Eniwetok Atoll. Collections from Eniwetok Atoll are compared with those made the same summer from other locations in the Southern and Western Pacific. A comparison is also made with the survey made by Cushman et al. of the Marshall Islands prior to bomb testing.

    Notes: SYNOPSIS. Blepharisma seculum sp. nov. is described as a small-sized blepharisma with a compact, spheroid macronucleus and a distinct curvature of the body anteriorly. A comparison of this form with other species of the genus Blepharisma subgenus (Compactum) is given.

    Nuclear Structure and Mitosis in the Dinoflagellate Gonyaulax monilata (1967)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 14 (1967), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Nuclear structure and mitosis in Gonyaulax monilata were studied. Between the arms of the U-shaped interphase nucleus is a band of material which, it is suggested, is homologous with the “central body” of G. tamarensis. Histochemical studies of whole cells, extruded nuclei and Epon-embedded sections indicate that the band is composed at least in part of protein, phospholipid and possibly RNA. The chromosomes of interphase nuclei are attached to the ends of the band. The band is also attached to a proteinaceous, extra-chromosomal matrix which pervades the nucleus. Studies on material treated with trypsin indicate that the matrix may be a factor in maintaining chromosomal integrity and orientation and nuclear form. During mitosis the band acts as a point of attachment for the chromosomes, and appears to control anaphase and telophase movements. It is suggested that the band is a component of the mitotic apparatus in G. monilata.

    DNA Synthesis Cycle in Blepharisma (1968)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 15 (1968), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Observations made with tritiated thymidine uptake indicate that Blepharisma cannot utilize this precursor directly from the organic medium. An intermediary, such as a food organism (bacteria or Tetrahymena, is needed. These food organisms are not only capable of incorporating thymidine from the medium, but must also break it down or prepare it in a form that is utilizable for Blepharisma.DNA synthesis phase in Blepharisma occurs 17 hours after division. Maximum incorporation is obtained 18 and 19 hours postdivision and lasts thru 24 hours. This is followed by a 1–2 hour postsynthesis phase and division.

    Macronuclear Variation During the Life Cycle of Blepharisma dawsoni n.sp. and B. wardsi (1967)

    Notes: SYNOPSIS. From characteristics of binary fission, conjugation, size and number of micronuclei, body size and incidence of giantism, a Blepharisma isolate hitherto called B. undulans is classified as B. dawsoni sp. nov. Binary fission in B. wardsi differs from fission in B. dawsoni in that the strand connecting the macronuclear nodes is severed; in B. dawsoni the strand persists.

    A Proposed Organization of the Genus Blepharisma Perty and Description of Four New Species (1965)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 12 (1965), S. 0

    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. The following four subgenera. I based chiefly on the form of the macronucleus, are proposed for thr genus Blepharisma Perty 1852: 1) Compactum, having a single compact interphase macronucleus. Type species B Compactum hyalinum Perty. 2) Filijormis, having a vermiform or tubular elongate interphase macronuclcus. occasionally doubled or even fragmented in individuals. Type spcies B. (Filiformis) intermedium Bhandary. 3) Blepharisma, having an interphase macronucleus with two or more nodes usually connected by a very thin strand between the nodes. Type species B. (Blepharisma) Perisicinum Perty. 4) Halteroides, having an interphase macronucleus in two nodes connected by a thick strand. Type species B. (Halteroides) tropicum Bhandary. Differences between the subgenera also can be found in the size, pigmentation, presence or absence of cysts and conjugaion 26 species are presented.While integradations between the subgenera and species exist, it is felt that separation of the four groups is warranted and may indicate possible evolutionary trends within the genus.
