Estimating Population Parameters of the Cladocera

ABSTRAKT

A new method for calculating birth rates in cladoceran populations during periods of time shorter than the duration of embryonic development (taking into account the age structure of eggs) was used for processing the results of observations on the Diaphanosoma brachyurum population dynamics in summer, obtained by means of daily sampling. The results showed that birth rate indices may change significantly during intervals shorter than three days. The accuracy of data on population dynamics increases as intervals between sampling become shorter. The main factors affecting the dynamics of D. brachyurum populations are ambient temperature and predation by other invertebrates.
