Notes
A new culture method for K. cochlearis has made it possible to study isolated animals and to investigate the population dynamics of this pelagic rotifer species. The duration of principal developmental stages diminishes continuously with temperature. Decreased survival was associated with a reduced duration of individual fecundity. The age distribution of the population shifted toward younger age intervals with higher temperatures. Growth rates had an optimum at 15 degrees C; the population dynamics, while lower for K. cochlearis than for some other rotifers, were in good agreement with field data.
