Use of genetic methods to establish male-biased dispersal in a cryptic mammal, the swamp wallaby (Wallabia bicolor)

摘要: Mammalian dispersal tends to be male-biased although female-biased has also been reported in a range of taxa. Most our knowledge on mammalian sex-biased is based studies eutherians and less work done the direction causes marsupials. This study investigated swamp wallabies between two habitat patches South Gippsland, Victoria, using genetic methods. A Bayesian clustering test showed high level exchange despite their separation by 10–17 km cleared land, creek highway. Females overall sample were more closely related each other than males females within whereas converse was true for males. inference that migrating from east west patch male migration rate higher female rate. The differential did not cause significant difference relatedness but it These patterns indicate wallaby male-biased.
