✦ Synopsis

The reproductive potential of two harpacticoid copepods, Tachidius dis~pes and Paronychocamptus nanus,

as measured by the intrinsic rate of natural increase, r m, has been studied. The influence of temperature on all factors used in the calculation of r m has been taken into account. Generation time, which has also been determined in a third species, Nitocra typica, is the single factor which is most affected by temperature and which has the most pronounced effect on r m. Values of the reproductive potential differ considerably according to temperature, and thus to the time of the year; during the spring bloom more than half the reproductive potential is realized.
