Highly plastic resource allocation to growth and reproduction in females of an African annual fish

Original language description

Phenotypic plasticity is an important mechanism to maximise fitness in unpredictable environments by fine-tuning phenotypes to a specific environmental setting. We used Nothobranchius furzeri, an African annual fish from temporary pools with erratic changes in habitat condition, to study changes in the allocation to growth and reproduction and to test the key trade-off between egg size and number. In an experimental setting, we quantitatively varied ration at two levels and over two time periods, including temporal switches in ration level. As predicted, female N.furzeri possessed the capacity for compensatory growth, which surprisingly came with no longer-term cost to fecundity. Females responded strongly to ration manipulation, with a pronounced decrease in fecundity associated with a low ration, even after accounting for body mass. Due to the unpredictability of offspring environment, we expected no adaptive change in oocyte size. However, females responded to the quality of their e
