Social constraint and an absence of sex-biased dispersal drive fine-scale genetic structure in white-winged choughs
Beck, Nadeena; Peakall, Rodney; Heinsohn, Robert
This study used eight polymorphic microsatellite loci to examine the relative effects of social organization and dispersal on fine-scale genetic structure in an obligately cooperative breeding bird, the white-winged chough (Corcorax melanorhamphos). Using both individual-level and population-level analyses, it was found that the majority of chough groups consisted of close relatives and there was significant differentiation among groups (FST = 0.124). However, spatial autocorrelation analysis...[Show more]
