| population structure and gene flow of the atlantic walrus (odobenus rosmarus rosmarus) in the eastern atlantic arctic based on mitochondrial dna and microsatellite variation. | the population structure of the atlantic walrus, odobenus rosmarus rosmarus, was studied using 11 polymorphic microsatellites and restriction fragment length polymorphism detected in the nadh-dehydrogenase nd1, nd2 and nd3/4 segments in mtdna. a total of 105 walrus samples were analysed from northwest (nw) greenland, east (e) greenland, svalbard and franz joseph land. two of the 10 haplotypes detected in the four samples were diagnostic for the nw greenland sample, which implied that the group o ... | 1998 | 9787444 |
| serum chemistry reference values in free-ranging north atlantic male walruses (odobenus rosmarus rosmarus) from the svalbard archipelago. | information regarding health and disease is limited for walruses, a keystone species in arctic marine ecosystems. serum chemistry analysis is a useful clinical tool for the health assessment of walruses, but only a few captive pacific walruses have been evaluated. | 2009 | 19473331 |
| genetic diversity of historical atlantic walruses (odobenus rosmarus rosmarus) from bjørnøya and håøya (tusenøyane), svalbard, norway. | the population size of atlantic walruses (odobenus rosmarus rosmarus) is depleted relative to historical abundance levels. in svalbard, centuries of over-exploitation brought the walrus herds to the verge of extinction, and such bottlenecks may have caused loss of genetic variation. to address this for svalbard walruses, mitochondrial haplotypes of historical walruses from two major haul-out sites, bjørnøya and håøya, within the archipelago were explored using bone samples from animals killed du ... | 2016 | 26892244 |
