An extensive debate concerning the origin and taxonomic status of wolf-like canids in the North American Great Lakes region and the consequences for conservation politics regarding these enigmatic predators is ongoing. Using maternally, paternally and biparentally inherited molecular markers, we demonstrate that the Great Lakes wolves are a unique population or ecotype of gray wolves. Furthermore, we show that the Great Lakes wolves experienced high degrees of ancient and recent introgression of coyote and western gray wolf mtDNA and Y-chromosome haplotypes, and that the recent demographic bottleneck caused by persecution and habitat depletion in the early 1900s is not reflected in the genetic data.
关于北美五大湖地区狼样犬科动物的起源和分类地位以及这些神秘食肉动物对保护政策影响的广泛辩论正在进行。利用母系、父系和双亲遗传分子标记，我们证明五大湖狼是灰狼的一个独特种群或生态型。此外，我们表明五大湖狼经历了郊狼和西部灰狼线粒体DNA和Y染色体单倍型的高度古老和近期渗入，并且20世纪初因迫害和栖息地枯竭导致的近期种群瓶颈并未在遗传数据中体现出来。
