AN ABSTRACT OF THE DISSERTATION OF PERCY L. DONAGHAY for the
Population dynamics of Skeletonema costatum in high dilution rate chemostats

Creator:

Donaghay, Percy L.

Abstract:

A chemostatic system was developed for the long term studies of population dynamics of chain forming diatoms. Vessel volume rather than flow rate was varied in these systems to obtain different growth rates at steady state in systems with an equal capacity to produce. Population level responses to high dilution...
