Dispersal influences genetic and acoustic spatial structure for both males and females in a tropical songbird

摘要: Animals exhibit diverse dispersal strategies, including sex-biased dispersal, a phenomenon common in vertebrates. Dispersal influences the genetic structure of populations as well geographic variation phenotypic traits. Patterns spatial and may vary between sexes whenever males females different behaviors. Here, we examine structure, acoustic Rufous-and-white Wrens, year-round resident tropical bird. Both sing this species, allowing us to compare relationship song sharing for both sexes. Using long-term dataset collected over an 11-year period, used banding data molecular analyses quantify natal breeding distance Wrens. We quantified examined whether varied with distance, females. Observational indicate that is female-biased. Females dispersed farther from territories than males, more often males. Furthermore, showed no significant consistent expectations, whereas structure. Overall, appears have influence on given majority events resulted individuals moving only short distances. Song pairs same-sex animals decreases their females, although exhibited significantly greater Lastly, measured sharing. found sons shared fewer songs fathers they territories, but daughters mothers was not correlated distance. Our results reveal cultural differences sexes, suggesting culture dispersal.
