Resumo: | Published studies on the demography and reproductive strategies of harpacticoid copepods are examined critically. At the technical level, the popular approximation &lt;i&gt;r&lt;/i&gt; = ln R&lt;sub&gt;0&lt;/sub&gt;/T&lt;sub&gt;c&lt;/sub&gt; 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 &lt;i&gt;ad hoc&lt;/i&gt; variants of &lt;i&gt;r&lt;/i&gt; and &lt;i&gt;R&lt;sub&gt;0&lt;/sub&gt;&lt;/i&gt; 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.
