Leptobrachium boringii microsatellite DNA female-biased dispersal the local resource competition hypothesis
Dispersal is an important area of ecological and evolutionary research. Although many studies have been conducted in mammals and birds, dispersal pattern in amphibians is still unclear. To verify dispersal patterns of amphibians, an?endangered species the Emei Moustache Toad (Leptobrachium boringii) was selected. In this study, we analyzed six genetic parameters: inbreeding coefficient (FIS), gene diversity (HS), the mean of corrected assignment index (mAIC), the variance of corrected assignment index (vAIC), relatedness (r) for all three years together and each year separately based on eight highly polymorphic microsatellite loci. Data in totaled across years and each year for 581 individuals captured during 2013–2015 revealed a significant female-biased dispersal pattern. Significantly higher FIS and HS in females, and lower mAIC and r for each year separately in females support that L.boringii displays female-biased dispersal, although r for the total dataset and vAIC tests did not show significant differences between the sexes. Female-biased dispersal patterns may be explained by the local resource competition hypothesis.
