Fig. 2. Short-term rejection rate of own eggs following experimental parasitism.

The proportion (in percentage) of clutches with own egg rejection 24 hours after experimental infection with foreign eggs in sympatric hosts artificially parasitized by cuckoo catfish (A), heterospecific cichlid (B), and in sham controls (handling only) (C), and in allopatric hosts parasitized by cuckoo catfish (D) and in sham controls (E). Females individually naïve to brood parasitism (white bars) and experienced host females (black bars) are distinguished. Asterisks denote statistically significant (P < 0.05) difference in the pairwise contrasts between naïve and experienced host females.
