Abstract

The evolutionary importance of hybridization as a source of new adaptive genetic variation is rapidly gaining recognition. Hybridization between coyotes and wolves may have introduced adaptive alleles into the coyote gene pool that facilitated an expansion in their geographic range and dietary niche. Furthermore, hybridization between coyotes and domestic dogs may facilitate adaptation to human‐dominated environments. We genotyped 63 ancestry‐informative single‐nucleotide polymorphisms in 427 canids to examine the prevalence, spatial distribution and the ecology of admixture in eastern coyotes. Using multivariate methods and Bayesian clustering analyses, we estimated the relative contributions of western coyotes, western and eastern wolves, and domestic dogs to the admixed ancestry of Ohio and eastern coyotes. We found that eastern coyotes form an extensive hybrid swarm, with all our samples having varying levels of admixture. Ohio coyotes, previously thought to be free of admixture, are also highly admixed with wolves and dogs. Coyotes in areas of high deer density are genetically more wolf‐like, suggesting that natural selection for wolf‐like traits may result in local adaptation at a fine geographic scale. Our results, in light of other previously published studies of admixture in Canis , revealed a pattern of sex‐biased hybridization, presumably generated by male wolves and dogs mating with female coyotes. This study is the most comprehensive genetic survey of admixture in eastern coyotes and demonstrates that the frequency and scope of hybridization can be quantified with relatively few ancestry‐informative markers.

  • Scientists found that 6% of Carmine's genome showed domestic dog ancestry, which may have had some influence on his behavior and coloration.

    “Scientists found that 6% of Carmine's genome showed domestic dog ancestry, which may have had some influence on his behavior and coloration (Monzón et al., 2014;Mowry et al., 2021).”

    From Of Rarity and Symbolism: Understanding Human Perceptions of Charismatic Color Morphs (2024) · cites this paper as Monzón et al., 2014

    The Results (Admixture; page unavailable) report dog ancestry in eastern coyotes, and the Discussion (Philosophical matters and implications for coyote and wolf management; page unavailable) raises the possibility that dog alleles affect adaptation to human-dominated environments. The paper does not identify Carmine, report 6% dog ancestry for him, or link his coloration or behavior to dog ancestry. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
