There was no relationship between the genetic distances between individuals and their dialect membership. High rates of gene flow were estimated between vocal dialects based on genetic differentiation. In addition, 5. The number of effective migrants per generation between dialects estimated with the micro- satellite data was roughly one-seventh the number estimated with mitochondrial control region sequence data from the same individuals, suggesting that gene flow may be female-biased.
Together, these results suggest that the observed mosaic pattern of geographic variation in vocalizations is maintained by learning of local call types by immigrant birds after disper- sal, amazon parrot dissertation.
We found no evidence that ongoing habitat fragmentation has contributed to cryptic population structure. The reduced dispersal hypothesis predicts that gene Vocal dialects have been documented in a range of bird flow will also be reduced between dialects. In this case there would individuals from one dialect to another.
Dispersal could be be no expectation of genetic structuring along dialect limited because immigrants to a new dialect experience boundaries no matter how long these boundaries have been reduced survival due to ecological specializations to present.

Of the remaining nine birds in our sample, six were nesting females at nests from which no chicks were sampled and three were non-nesting birds. Materials and methods We extracted DNA from either feather tips or blood samples preserved in lysis buffer Longmire et al.

Products were sized on Genetic Analyser Applied Biosystems with genescan version 3. Genotypes were scored using genotyper version 2. Positive controls were included to ensure consistent size scoring across all runs. All loci showed Mendelian inheritance indicating autosomal linkage.
