重新发现曾经被认为灭绝或濒临灭绝的物种是罕见的。自1980年以来，红狼在美国墨西哥湾沿岸沿着已经灭绝，最后一批红狼出现在路易斯安那州和德克萨斯州沿海地区。我们报告了在德克萨斯州加尔维斯顿岛的犬科动物种群中重新发现的红狼幽灵等位基因。我们分析了超过7000个单核苷酸多态性（SNP）在60犬科动物的代表，从所有法律认可的北美犬种和两个表型模糊的犬科动物从加尔维斯顿岛。我们发现，显着高贝叶斯聚类分配的加尔维斯顿犬科动物圈养红狼广泛共享红狼私人等位基因。今天，唯一已知的现存野生红狼仍然存在于北卡罗来纳州的一个重新引入的种群中，这个种群在政治和分类学的争议中逐渐减少。近40年后，我们重新发现了红狼的祖先，这既为采取更多的保护行动带来了积极的机会，也带来了困难的政策挑战。
Rediscovering species once thought to be extinct or on the edge of extinction is rare. Red wolves have been extinct along the American Gulf Coast since 1980, with their last populations found in coastal Louisiana and Texas. We report the rediscovery of red wolf ghost alleles in a canid population on Galveston Island, Texas. We analyzed over 7000 single nucleotide polymorphisms (SNPs) in 60 canid representatives from all legally recognized North American Canis species and two phenotypically ambiguous canids from Galveston Island. We found notably high Bayesian cluster assignments of the Galveston canids to captive red wolves with extensive sharing of red wolf private alleles. Today, the only known extant wild red wolves persist in a reintroduced population in North Carolina, which is dwindling amongst political and taxonomic controversy. Our rediscovery of red wolf ancestry after almost 40 years introduces both positive opportunities for additional conservation action and difficult policy challenges.
