关于北美大湖区狼状犬科动物的起源和分类地位以及这些神秘的捕食者对保护政治的影响的广泛辩论正在进行中。利用母系、父系和双亲遗传分子标记，我们证明了五大湖狼是灰狼的一个独特的种群或生态型。此外，我们还发现，五大湖狼经历了古代和现代高度的郊狼和西部灰狼mtDNA和Y染色体单倍型的导入，而20世纪初因迫害和栖息地枯竭而造成的人口瓶颈并没有反映在遗传数据中。
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.
