| 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 <i>Paranychocamptus nanus</i> and <i>Tachidius discipes</i> a large part of the variation in time scales longer than 1 year is explainable as cyclic factors. In <i>P. nanus</i> clear cycles with periods of 2 years and 1.5 years were found. These cyclic factors can be extrapolated for prediction. In <i>Canuella perplexa</i> 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 <i>P. nanus</i> series showed that the essential features of the series were still discernible.
