Bi-parentally Inherited Genetic Evidence for Male-Biased Dispersal in Common Moorhen (Gallinula chloropus)

摘要: Dispersal is a life history trait that has relevant effect on both the dynamics and genetics of species sex-biased dispersal depends how resource competition affects each sexes. In this study, total 210 blood samples including 121 Common Moorhen (Gallinula chloropus) females 89 males were collected from 18 diverse areas during breeding season. Based 8 microsatellite markers analyses, we found most genetic diversities female populations higher than those males, where only 2 male individuals identified as long-distance dispersal. Analyses conducted over all sampling sites indicated mAI (female = 0.195, - 0.265, P 0.01), FST 0.045, 0.026, 0.020), r 0.118, 0.064, 0.010) in significantly at 0.05 level, which suggested male-biased pattern species. Our Mantel test results significant isolation-by-distance for but not corresponded to more frequent gene flow females. This could be explained by special mating system pair formation occurs before they leave flock spring establish territories its initiate courtship frequently compete with other small large fat reserves. The philopatric benefit knowledge particular area because may win intrasexual competitions season able produce offspring if are familiar local resources.
