    Notes: . A new foraminiferan species, Rotaliella elatiana n. sp., was isolated in the Gulf of Elat, where it lives in association with a macrophytic green alga, Enteromorpha. The agamont of this tiny new species has a transparent test composed of a bilocular embryonic chamber followed by six to seven trochospirally coiled inflated chambers. The spiral sutures are undulated. The umbilical side has numerous denticules and has radial grooves. The gamont has only one inflated chamber. Rotaliella elatiana has a classical, heterophasic life cycle, with a regular alternation of diploid agamontic phase and haploid gamontic phase. The gamontic phase of the life cycle is exceptionally reduced and the uninucleated gamonts pair immediately after they build their first chamber. A few cases of autogamic reproduction were observed. R. elatiana is a heterocaryotic species; agamonts have one somatic and two to three generative nuclei.

    Contributions to the Life Cycle of Peneroplis planatus (Fichtel and Moll) Montfort (1993)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 40 (1993), S. 0

    Notes: Direct observations of schizonts and agamonts releasing megalospheres clarified the asexual phase of the life cycle of Peneroplis planatus and made it most probable that this species has a paratrimorphic life cycle. Specimens with maximum lengths between 837 and 3,503 μm released about 500 to 1,500 megalospheric juveniles, which possessed two chambers (proloculi and flexostyles) prior to emergence from the parental shell. The presence of gamonts was not shown and was only implied by the occurrence of the agamonts. Since agamonts and schizonts have been found from December to May and since asexual reproduction occurs in spring in Elat, sexual reproduction probably occurs at another time of year (June to December). More detailed studies of this species need to be conducted throughout the year to improve our knowledge of the life cycle of this species.

    Informational Energy Flow As an Aspect of Protozoan Nutrition, (1980)

    Notes: SYNOPSIS The time is ripe for protozoan ecologists to begin the general evaluation of the role of food quality in the energy transformations and materials flow in food webs involving protozoa and other small organisms. Current evidence suggests that major pathways of energy flow at any particular time depend upon the matches between prey species and consumers. There are 2 components to food quality related (informational) energy flow: (a) the information present in the molecular constitution of the prey; and (b) the ability of the protozoa to recognize and use it. If the evidence obtained from trophodynamic studies of 2 marine ciliates, Uronema marinum Dujardin and Euplotes vannus Müller indicates a generalized ability of protozoa to regulate catabolic reactions to points which optimize energetic gains from their food, then it may be one of the keys to the evolutionary successes of the group.
