Resumo: | The predictability of temporal changes was analysed in the population density of three meiobenthic copepod species, and for three parameters characterizing this community. For &lt;i&gt;Paranychocamptus nanus&lt;/i&gt; and &lt;i&gt;Tachidius discipes&lt;/i&gt; a large part of the variation in time scales longer than 1 year is explainable as cyclic factors. In &lt;i&gt;P. nanus&lt;/i&gt; clear cycles with periods of 2 years and 1.5 years were found. These cyclic factors can be extrapolated for prediction. In &lt;i&gt;Canuella perplexa&lt;/i&gt; almost all the variation was due to unpredictable long-term drift. Community parameters are generally better predicted than population densities. In our data set total density of the copepods was the best parameter to monitor. Monitoring does not necessitate a strict sampling scheme; irregular quarterly sampling from the &lt;i&gt;P. nanus&lt;/i&gt; series showed that the essential features of the series were still discernible.
