    Notes: SYNOPSIS. Polysphondylium pallidum WS-320 grows indefinitely as vegetative amebae in a liquid medium where (a) substrates comprise sucrose, glycerol, acetate, lactate, citrate, and glutamate; (b) essential nutrients (riboflavin, lysine, glycine, and possibly several other amino acids that may be essential) are supplied. The growth thus supported (2 × 106 cells/ml) is more than doubled by provision of a mixture of crude fatty acids, an acid hydrolysate of casein supplemented with B vitamins, purines, pyrimidines, and fat-soluble antioxidants.

    Notes: SYNOPSIS. A polymorphic allogromiid (our strain NF) was isolated in monoxenic culture but attempts at its axenic culture failed. Growth of monoxenic cultures was stimulated by various metals and vitamins. The morphology and life cycle of this allogromiid with a prominent collar have been studied in detail. It varied in form from ovoid to elongate bioral “Shepheardella-like” forms and to irregular polyoral organisms. The organisms ranged in length from 56–385 μ (118 μ± 50.54) and in width from 35–385 μ (99 μ± 39.34). The number of nuclei per organism averaged 8.9 ± 6.3 (range 1–40). Reproduction of “Shepheardella-like” forms was by binary fission. Three types of budding have been observed and, rarely, schizogony. No evidence for sexual reproduction has thus far been seen.

    Tracer Experiments in Feeding Littoral Foraminifera (1966)

    ISSN: 1550-7408

    Topics: Biology
    Notes: SYNOPSIS. Tracer technic has proved to be an excellent tool in the study of predator-prey relationships among the foraminifera. More than fifty axenic species of protists including diatoms, dinoflagellates, chlorophytes, chrysophytes, cyanophytes, bacteria and yeasts were tested as potential food for Allogromia sp (NF), A. laticollaris, Am. monia beccarii, Quinqueloculina spp, Rosalina floridana, Anomalina sp, Elphidium sp, Spiroloculina hyalina, Globigerina bulloides, and Globorotalia truncatulinoides. Although many types of potential food are present in the environment, foraminifera select only certain organisms. The yeasts, cyanophytes, dinoflagellates, chrysophytes and most bacteria tested were not eaten. Selected species of diatoms, chlorophytes and bacteria were eaten in large quantity. Three additional factors affect feeding: the “age” of the food organism, the “age” of the foraminifer or its position in the life cycle, and the concentration of the food. Feeding by foraminifera on most food is erratic below a concentration of 103 organisms and is approximately directly proportional to concentration within a range of 103-106 organisms per 10 ml experimental tube. A natural bloom of Protelphidium tisburyensis was analyzed. A high concentration of 6 species of diatoms characterized the community. A “bloom”-feeder hypothesis for foraminiferal nutrition is presented.

    Notes: SYNOPSIS. Two new dinoflagellates, isolated from Long Island Sound and maintained axenically, are described. Gyrodinium instriatum n. sp. changes shape and size as cultures age. Glenodinium halli n. sp. is a delicately-armored form whose plate structure differs slightly from the present diagnosis of the genus, but not sufficiently like any other genus in morphology or life history for inclusion elsewhere. In G. halli the size of the motile form and predominance of motile or vegetative stages are nutrient dependent. Both dinoflagellates illustrate the need for morphological descriptions based upon continuous culture methods in defined media.

    Prolonged Culture of the Voracious Flagellate Peranema in Antioxidant-Containing Media (1966)

    Notes: SYNOPSIS. Peranema trichophorum remained vigorous at least a year in milk-lecithin media and 3 months in a nearly defined autoclavable biphasic agar medium fortified with the fat-soluble antioxidant butylated hydroxytoluene. The only undefined substance in the present “defined” medium is crude soybean lecithin; 0.001% lecithin suffices in the presence of a mixture of long-chain saturated and unsaturated fatty acids. Linoleic acid may be indispensable. Histidine is an absolute requirement as well as a favored substrate. Cholesterol, not ergosterol, satisfied the sterol requirement. Voracity is retained in these media as shown by engorgement on plastic latex particles.

    Cytological Observations on Two Planktonic Foraminifera, Globigerina bulloides d'Orbigny, 1826, and Globigerinoides ruber (d'Orbigny, 1839) Cushman, 1927 (1965)

    Notes: SYNOPSIS. Globigerina bulloides and Globigerinoides ruber, two pelagic foraminifera from the North Atlantic, were fixed in modified Zenker or Bouin solutions directly after collection and studied cytochemically. They have two unusual organelles: a vesicular system and an organelle provisionally named a “cryptosome.” The vesicular system occurs chiefly in the newest formed chambers and consists of a pair of intertwined tubules with helical fine structure which terminate in a bouquet of approximately 20 vesicles or loops. The function of this system is unknown. The detailed morphology of the vesicular system is different in each species. The cryptosome is a structure which varies greatly in its morphology. It is better developed in G. bulloides than it is in G. ruber. At times a cryptosome may occupy up to 2/3 of the protoplasm of a chamber. In Himes-Moriber-stained preparations crypto-somes stain with naphthol yellow S and contain within them an azure A-Schiff staining spongy reticulum. Both of the pelagic foraminifera studied are heterokaryotic. Agamonts of G. ruber may have a graded series of nuclear sizes but those of G. bulloides typically have a single somatic nucleus. The zooxanthellae of G. ruber are similar to Symbiodinium microadriaticum and may collectively occupy almost 4/5 the volume of a chamber.

    Isolation and characterization of the “zooxanthellae” from soritid foraminifera and the giant clam Tridacna maxima (2005)

    Notes: Various methodological approaches are being used to characterize Symbiodinium spp isolated from Marginopora vertebralis and Amphisorus hemprichii and Amphisorus sp. from the Indo-pacific. While most of the cells in culture are non-motile vegetative cells, dinospores occur in batch cultures. We find consistant variance among the isolates in the duration and time of appearance of motile forms. Nitrate (0.146 mM) supports higher populations of the isolates than NH4 (0.146 mM). Higher concentrations of NH4 inhibit growth. Although Fensome et al. (1993) characterized the Order Suessiales (and Family Symbiodiniaceae) as gymnnodiniphycideans in which the amphiesmal vesicals are arranged in 7–10 longitudinal series we were unable to detect any plates on the surfaces of our isolates in the SEM. We were unsuccessful in revealing plates on non-motile forms by freeze fracture but they were present after treatment with various chemical agents (e.g. H2O2, HOCl−) and enzymes (cellulase, chitinase). They are not polygonal or arranged in the patterns anticipated for the Symbiodiniaceae. Polyclonal antibody studies of the Symbiodinium-like isolates are in agreement with molecular systematic studies in the sense that there is a common relation. The foram endosymbiotic dinoflagellates share some common surface antigens with each other and with the few invertebrate isolates we have tested. Studies of the foraminiferal symbionts' plastids revealed considerable morphological diversity. We isolated a diversity of endosymbionts from the mantle of Tridacna maxima from the Red Sea and the Marshall Islands. These included Symbiodinium, Amphidinium, Tetraselmis, and an unidentified chlorophyte.

    Quantitative Studies on the Growth of Allogromia laticollaris (Foraminifera) (1969)

    Notes: SYNOPSIS. The growth and reproduction of Allogromia laticollaris was studied. More schizozoites were generally produced in mixtures of food organisms than on single algal foods. In the presence of moderate numbers of bacteria, cultures with Phaeodactylum tricornutum, Chlorococcum sp., Nannochloris sp., and an unidentified chlorophyte (BL-1), added singly, were also highly productive. Schizogony was the dominant asexual form of reproduction. Binary fission and cytotomy also occurred in bacterized otherwise unfed controls. 35S and 32P are convenient labels for measuring growth of A. laticollaris when introduced into the system in the range of 1 × 104 - 1 × 105 dpm/ml (32P specific activity ∼ 2.03 MCi/g; 35S specific activity ∼ 95 μCi/g). Small allogromiids grew faster than did larger ones. By means of the Taylor series modification of the classical least-squares method, a continuous life-cycle representation was calculated for A. laticollaris for the conditions of the experiment. Four points of cell volume growth were maxima for reproduction: 1.0 × 107μ per organism for curve I; 2.2 × 107μ3 and 1.2 × 107μ3 for curve II; and 6.7 × 107μ3 for curve III.
