Resumo: 	Caswell and Hastings (1980) introduced an explicit model for the relative merits, in terms of growth rate &lt;i&gt;lambda&lt;/i&gt;, of developmental shifts vs. fecundity increases. Some aspects of their model are clarified by concentrating on the (fitness &gt;1) half-plane rather than on the (accelerated reproduction) half-plane. There is no strict equivalence between Caswell and Hastings' key parameter &lt;i&gt;lambda/P&lt;/i&gt; and the dynamic behaviour of the population which is governed by &lt;i&gt;lambda&lt;/i&gt;. Thus in some stationary/declining populations time shifts of reproduction (forward or backward, according to the value of &lt;i&gt;lambda/P&lt;/i&gt;) are just as effective in promoting a high &lt;i&gt;lambda&lt;/i&gt; as they are in growing populations; therefore selection for higher &lt;i&gt;m&lt;/i&gt;, may, but need not, prevail in stationary/declining populations.
