Abstract: | The tufted duck (Aythya fuligula, Anatidae) is widespread in the Palaearctic across Northern Eurasia. Birds breeding in Northern and Eastern Europe are highly
migratory, while populations from Western Europe are partially migratory or resident. The aim of this study is to explore
genetic variation within and between ducks breeding in Latvia and migrants sampled in North West Russia and Belarus. The technique
of random amplified polymorphic DNA was applied using five random primers (ol-1, ol-9-12). Genetic variability was measured for all tufted ducks investigated and for different sub-populations from various regions.
Individual genetic structure and genetic variability was higher in ducks collected from Latvia. Gene diversity of amplified
DNA bands in birds of Latvian origin was 24% with 80% polymorphism. Means of gene diversity and polymorphism for tufted ducks
sampled in other countries varied from 12 to 14% and from 27 to 40%, respectively. A high number of unique bands characterized
ducks breeding in Latvia. The oligonucleotide primers used in this study were suitable to analyze differences among tufted
ducks of different origin. Possible explanations for the variation observed among the studied ducks are discussed. |
