- Abstract
Among freshwater zooplankton, rotifers and cladocerans reproduce parthenogenetically and the cost of reproduction can be estimated using the life table data from demographic studies. Reduced probability of future survival or future reproduction as a result of current investment in offspring production is the central theme of the cost hypothesis. Correlations using present reproduction vs. future reproduction (reproductive costs) or future survival (survival costs) can be used to evaluate the cost hypothesis. In this work sets of correlations were made between present reproduction vs. future survival and present reproduction vs. future reproduction. These correlations were plotted against the cohort age-classes in order to quantify survival and reproductive costs in rotifers and cladocerans. Data supported the cost hypothesis in the majority of cases where reproduction by zooplankton of a given age class caused reduced survival and reproduction of the next age class.
