Reproductive rates, operational sex ratios and mate choice in St. Peter’s fish
Abstract
Abstract Operational sex ratio (OSR) theory predicts that sexual differences in potential reproductive rates (PRRs) create biases in the OSR and thus determine the relative strength of sexual selection (competition and choice) operating on each sex. Although this theory is well accepted, empirical studies that quantify it are still lacking. This paper presents such a study. I measured the natural OSR of Galilee St. Peter’s fish (Sarotherodon …
