Genetic analysis of the population structure of socially organized oystercatchers (Haematopus ostralegus) using microsatellites.

abstract：:Comparisons among patterns exhibited by functionally distinct genetic markers have been widely used to infer the impacts of demography and selection in structuring genetic variation in natural populations. However, such multilocus comparisons remain an indirect evaluation of selection at particular candidate loci; ide...
