ABSTRACT

Abstract. Many environments occupied by North American sea ducks are remote and difcult to access, and as a result, detailed information about life history characteristics that drive population dynamics within and across species is limited. Nevertheless, progress on this front during the past several decades has beneted by the application of genetic technologies, and for several species, these technologies have allowed for concomitant tracking of population trends and genetic diversity, delineation of populations, assessment of gene ow among metapopulations, and understanding of migratory connectivity between breeding and wintering grounds.
