Genetic differentiation among populations of the Roseate spoonbill (Platalea ajaja; Aves: Pelecaniformes) in three Brazilian wetlands
Effective population size, levels of genetic diversity, gene flow, and genetic structuring were assessed in 205 colonial Roseate spoonbills from 11 breeding colonies from north, central west, and south Brazil. Colonies and regions exhibited similar moderate levels of diversity at five microsatellite...
