| Resumo: |
Published studies on the demography and reproductive strategies of harpacticoid copepods are examined critically. At the technical level, the popular approximation <i>r</i> = ln R<sub>0</sub>/T<sub>c</sub> is shown to be inappropriate as an estimate of the intrinsic rate of increase of harpacticoids. It leads to a systematic underestimation, by 8-29%, for life histories typical of fast-breeding species. Various <i>ad hoc</i> variants of <i>r</i> and <i>R<sub>0</sub></i> calculations occurring in the literature are also criticized. At the conceptual level, a more discriminating approach to life-history characteristics is necessary; this applies both to the assessment of their 'strategic' significance, and to their diagnostic power with regard to the various 'strategies'. Special attention is given to the non-equivalence of parity and voltinism. Recommendations that should promote the construction of a more rigorous cognitive framework are included.
