    Size-structure dynamics of the rotifer chemostat: a simple physiologically structured model (1998)
    Springer
    Hydrobiologia 387-388 (1998), S. 469-476 
    Details
    ISSN: 1573-5117
    Keywords: population dynamics ; size structure ; dilution rate

    Topics: Biology
    Notes: Abstract The classical chemostat models of Monod and others were designed for unicellular organisms. We summarize evidence that these models are not adequate for the rotifer chemostat, then propose a new, physiologically structured model that resolves some of their key problems yet remains biologically simple. The new model includes separate ontogenetic stages for eggs and free-swimming rotifers, with generalized age structure in the egg stage and body mass structure in the free-swimming stage. We present several numerical examples to illustrate the model's behavior, and we compare these in a preliminary way with experimental evidence from the literature.

    Rotifer size distribution changes during transient phases in open cultures (1998)
    Springer
    Hydrobiologia 387-388 (1998), S. 477-482 
    Details
    ISSN: 1573-5117
    Keywords: Rotifera ; Brachionus ruhens ; Brachionus calyciflorus ; population dynamics ; steady-state growth ; continuous culture ; size distributions

    Topics: Biology
    Notes: Abstract In laboratory studies, rotifers (Brachionus calyciflorus) were monitored under well-defined environmental conditions at different supply rates of a unicellular algal food (Chlorella vulgaris). Rotifer size frequency distributions are described for conditions of steady-state growth, exponential increase, and starvation. Temporal fluctuations in size-age structure are described for cultures during transient conditions during the approach to a steady state and following step changes in food supply rate. The size structures of the populations displayed definite and reproducible shifts among typical patterns during transient conditions, reflecting the physiological and other dynamic processes that underlay the population dynamics. Size structure probably is a key variable that should be included in models for predicting growth dynamics during transient growth conditions.
