| Summary: | Additive genetic variance in fitness is a prerequisite for adaptive evolution, as a trait must be genetically correlated with fitness to evolve. Despite its relevance, additive genetic variance in fitness has not often been estimated in nature. Here, we investigate additive genetic variance in lifetime and annual fitness components in common terns (Sterna hirundo). Using 28 years of data comprising ca. 6000 pedigreed individuals, we find that additive genetic variances in the Zero-inflated and Poisson components of lifetime fitness were effectively zero, but estimated with high uncertainty. Similarly, additive genetic variances in adult annual reproductive success and survival did not differ from zero, but were again associated with high uncertainty. Simulations suggested that we would be able to detect additive genetic variances as low as 0.05 for the Zero-inflated component of fitness, but not for the Poisson component, for which adequate statistical power would require c. two more decades (four tern ... : Data used for models presented in: The quantitative genetics of fitness in a wild seabird by Moiron M., Charmantier A. and Bouwhuis S. published in Evolution For information regarding the analyses, please contact mariamoironc@gmail.com For information regarding the data, please contact sandra.bouwhuis@ifv-vogelwarte.de If you'd like to use the data, please also contact sandra.bouwhuis@ifv-vogelwarte.de These data are part of those collected in an ongoing individual-based longitudinal population study Additional data are likely to be available, and we are often very happy to collaborate provided that none of our own staff or students is working on a conflicting project ... |
