Resumo: | The life-cycle of &lt;i&gt;Rhabditis marina&lt;/i&gt; Bastian 1865 was studied at 25°C and 20 promille salinity. The following demographic parameters were computed from life-table data: the intrinsic rate of natural increase (r&lt;sub&gt;m&lt;/sub&gt;) = 0.914 day; net reproductivity (R&lt;sub&gt;0&lt;/sub&gt;) = 400; minimum generation time (T&lt;sub&gt;min&lt;/sub&gt;) = 4.5 days; cohort generation time (T&lt;sub&gt;c&lt;/sub&gt;) = 7.2 days; mean generation time (T) = 6.6 days; and the age of an adult female when a median egg is deposited (T) = 6.1 days. Several approximate equations used to estimate r&lt;sub&gt;m&lt;/sub&gt; were compared with these life-table calculations. Some give erroneous estimations and should be used with extreme caution. For iteroparous organisms (including most free-living nematodes), T&lt;sub&gt;min&lt;/sub&gt; only gives an indication of the development time and is therefore unsuitable for describing "mean generation time".
