Synthesis Northeastern coyote / coywolf taxonomy and admixture : A meta-analysis

  title={Synthesis Northeastern coyote / coywolf taxonomy and admixture : A meta-analysis},
  author={Jonathan G. Way and William S Lynn},
A flurry of recent papers have attempted to taxonomically characterise eastern canids, mainly grey wolves Canis lupus, eastern wolves Canis lycaon or Canis lupus lycaon and northeastern coyotes or coywolves Canis latrans, Canis latrans var. or Canis latrans x C. lycaon, in northeastern North America. In this paper, we performed a meta-analysis on northeastern coyote taxonomy by comparing results across studies to synthesise what is known about genetic admixture and taxonomy of this animal… 

Spatial genetic analysis of coyotes in New York State

It is suggested that the contact zone between coyote colonization fronts has either eroded or moved further south in New York, indicating that local abundance and ecological context rather than genetic lineage are likely to determine the local ecological effects of coyotes in this region.

Geographic patterns in morphometric and genetic variation for coyote populations with emphasis on southeastern coyotes

It is offered that the larger body size of eastern coyotes reflects an adaptation that improved dispersal capabilities of individuals in the expanding range, and it is postulate that southeastern coyotes experienced lower immigration from western populations than did northeastern coyotes, and over time, genetically diverged from both western and northeastern populations.

Response Comment on “ northeastern coyote / coywolf ” taxonomy and admixture

Recently, Way and Lynn (hereafter “the authors”; 2016) conducted a thorough literature review (or “meta-analysis” in their words, although no formal meta-analysis [sensu Arnqvist and Wooster 1995]

The hybrid skull of the eastern coyote (Canis latrans var.): Nonmetric traits and craniomandibular shape

The exploration of morphometric variation identifies intermediate morphology in the hybrids, and some indication of greater morphological variability in the mandible, suggesting that skeletal signatures of hybridization are common to different mammalian taxa across multiple generations.

Predatory behaviors of coyotes (Canis latrans) living in coastal ecosystems

The coyote is a living contradiction and the search for generalities about the species can be a fruitless expedition littered with caveats, so a discussion of their predatory behavior, with new accounts and observations, may buttress ongoing studies and management regimes.

Hybridization in human evolution: Insights from other organisms

A range of examples relevant to questions about the evolution of hominins are presented, highlighting potential drivers of human evolution in the context of hybridization including: influences on adaptive evolution, climate change, developmental systems, sex‐differences in behavior, Haldane's rule and the large X‐effect, and transgressive phenotypic variation.

The natural history and ecology of melanism in red wolf and coyote populations of the southeastern United States – evidence for Gloger’s rule

Background Gloger’s rule postulates that animals should be darker colored in warm and humid regions where dense vegetation and dark environments are common. Although rare in Canis populations,



Taxonomic Implications of Morphological and Genetic Differences in Northeastern Coyotes (Coywolves) ( Canis latrans × C. lycaon ), Western Coyotes ( C. latrans ), and Eastern Wolves ( C. lycaon or C. lupus lycaon )

  • J. Way

  • 2013
The body mass of eastern (i.e., northeastern) Coyotes, western Coyotes, and Eastern Wolves is compared and it is proposed that the 5 distinct types of Canis be recognized as: western Coyote, Coywolf (northeastern Coyote), Eastern Wolf (including Red Wolf C. rufus ), Gray × Eastern Wolf hybrids (‘Great Lakes’ Wolves), and Gray Wolf (C. lupus × C. lycaon or C. l upus ).

Genetic and morphological differentiation of wolves (Canis lupus) and coyotes (Canis latrans) in northeastern Ontario

It is suggested that wolves and coyotes in the sampled area can be reliably distinguished, but further sampling is required to determine the full extent of this ability.

An Account of the Taxonomy of North American Wolves From Morphological and Genetic Analyses

Genetic data support a close relationship between eastern wolf and red wolf Canis rufus, but do not support the proposal that they are the same species; it is more likely that they evolved independently from different lineages of a common ancestor with coyotes.

Moose (Alces alces) predation by eastern coyotes (Canis latrans) and eastern coyote × eastern wolf (Canis latrans × Canis lycaon) hybrids

Predation by coyotes and coyote × wolf hybrids probably does not represent a threat to moose population viability in central Ontario, but the results suggest that researchers and managers in other areas with declining moose populations that are sympatric with eastern coyote and (or) coyote → wolf hybrids should consider coyote predation as a potential source of mortality.

Landscape Influence on Canis Morphological and Ecological Variation in a Coyote-Wolf C. lupus × latrans Hybrid Zone, Southeastern Ontario

The ecology of Coyote-Wolf ( Canis latrans × C. lupus ) hybrids has never fully been typified. We studied morphological and ecological variation in Canis within a region of Coyote-Wolf hybridization

Coyote colonization of northern Virginia and admixture with Great Lakes wolves

Noninvasive molecular techniques are used to detect the geographic origins of the recent coyote colonization of northern Virginia as a representative of the mid-Atlantic region and to detect signatures of admixture with GLWs.

Genetic Characterization of Eastern “Coyotes” in Eastern Massachusetts

Results indicate that the eastern Coyote should more appropriately be termed “Coywolf” to reflect their hybrid (C. latrans x lycaon) origin.

Sympatric wolf and coyote populations of the western Great Lakes region are reproductively isolated

A genetic analysis of sympatric wolves and coyotes from the western Great Lakes region concludes that they are reproductively isolated and that wolf–coyote hybridization in the WGLR is uncommon, and concludes that the extant W GLR wolf population is derived from hybridization between grey wolves and eastern wolves.

A Perspective on the Genetic Composition of Eastern Coyotes

Abstract Way et al. (2010) define a “coywolf” population in the northeastern United States and eastern Canada that originated through hybridization between Canis lycaon (Eastern Wolf) and Canis

Spatial genetic and morphologic structure of wolves and coyotes in relation to environmental heterogeneity in a Canis hybrid zone

This work studied resident wolves and coyotes in and adjacent to APP to identify distinct Canis types, clarify the extent of the APP eastern wolf population beyond the park boundaries and investigate fine‐scale spatial genetic structure and landscape–genotype associations in the hybrid zone.
