These lineages, which partly coincide with subspecies described based on plumage variation and body size, do not share mtDNA haplotypes, have private nuclear alleles and exhibit marked differences in morphometric traits. We found deep subdivisions of Torrent Duck populations from the northern, central and southern portions of the Andes. We examined evidence from genetic and morphological data to address questions about the biogeography and taxonomy of the Torrent Duck ( Merganetta armata), a riverine specialist bird with a broad distribution in Andean riverine habitats which certainly comprises different subspecies and may comprise more than one species. Although several bird species are riverine specialists in the Andes, no study has extensively evaluated the population genetic structure of any of them.
Alternatively, the configuration of river networks may result in restricted dispersal within river courses or basins, leading to high genetic structure. Soon wires get crossed, and all hell breaks loose.Birds living in riverine environments may show weak population structure because high dispersal abilities required to track habitat dynamics can result in gene flow over broad spatial scales. Little does Rosie suspect, however, that her friend is sleeping with her lover Georg, an uptight journalist with an ego the size of Finland. Meanwhile, Nenne's friend and co-worker Rosie suspects that Frank is having an affair, though she does not have the nerve to tell her. Eventually, Frank shacks up with a young fetching art student named Sofia, though the experience wracks Frank with guilt. He even fantasizes about the marriage counselor that he and Nenne visit weekly. Yet Frank is deeply bored with his life and is supremely randy. He has also been married for eight years to his beautiful wife Nenne, who runs an upscale boutique.
Frank leads a respectable yuppie life working at a noted Stockholm law firm.
