The Guadalupe fur seal (Arctocephalus townsendi) population underwent one or two severe bottlenecks due to commercial sealing in the late 19th century. Since then the protected population has been growing steadily around their only rookery, Isla de Guadalupe, Mexico. We probed both nuclear and mitochondrial genomes using multilocus nuclear DNA profiling and mitochondrial DNA sequencing to estimate the level of genetic variability of the present population. Unlike other pinniped populations that have experienced similar historical bottlenecks, such as Hawaiian monk seals and northern elephant seals, high levels of genetic variability were found.
瓜达卢佩海狗（Arctocephalus townsendi）种群在19世纪后期由于商业捕杀而经历了一到两次严重的瓶颈期。从那时起，受到保护的种群在其唯一的繁殖地——墨西哥的瓜达卢佩岛周围稳步增长。我们使用多位点核DNA分析和线粒体DNA测序对核基因组和线粒体基因组进行了探测，以估计当前种群的遗传变异水平。与其他经历过类似历史瓶颈的鳍足类种群不同，如夏威夷僧海豹和北海象海豹，我们发现瓜达卢佩海狗种群具有高水平的遗传变异。
