我们使用淀粉凝胶电泳研究23个位点的遗传变异，在107个人从7个种群的斑点猫头鹰（Strix oceanentalis）。这些种群采样所有三个目前公认的亚种。在来自俄勒冈州和加州的6个群体中未发现遗传变异。新墨西哥州猫头鹰的平均杂合性为0.022。低水平的遗传变异性将使其更难以监测这一受威胁物种的遗传;变异的缺乏可能是由于一个小的整体有效的人口规模或瓶颈在过去。在一个位点上，太平洋沿岸人群（S。O. caurina和S. O. occupentalis）和异域分类群（S. O. lucida）发现于新墨西哥州;我们估计FST为0.55。我们相信这两个异地种群长期以来一直被隔离，很可能它们代表了两个物种。这些数据无助于阐明S的亚种地位。O.珊瑚虫。
We used starch-gel electrophoresis to investigate genetic variability at 23 loci in 107 individuals from seven populations of the Spotted Owl (Strix occidentalis). These populations sample all three currently recognized subspecies. No genetic variation was found in six populations from Oregon and California. Average heterozygosity in owls from New Mexico was 0.022. The low level of genetic variability will make it more difficult to monitor the genetics of this threatened species; the paucity of variation is possibly due to a small overall effective population size or bottlenecks in the past. At one locus there was a major allelic frequency difference between the Pacific Coast populations (S. o. caurina and S. o. occidentalis) and the allopatric taxon (S. o. lucida) found in New Mexico; our estimate of FST is 0.55. We believe the two allopatric populations have long been isolated, and it is probable that they represent two species. The data do not help elucidate the subspecific status of S. o. caurina.
