Evaluating the Taxonomic Status of the Mexican Gray Wolf and the Red Wolf

Taxonomy—the scientific study of biological classification—enables scientists to name and group living organisms. However, because species are dynamic and not fixed entities, taxonomic designations are often debated. At any given time, different populations can be in different stages in the … read more

Dogs Have ‘Happy Gene’ That Make Them Friendlier, Different From Wolves

Structural variants in genes associated with human Williams-Beuren syndrome underlie stereotypical hypersociability in domestic dogs Although considerable progress has been made in understanding the genetic basis of morphologic traits (for example, body size and coat color) in dogs and wolves, … read more

Comment On “whole Genome Sequence Analysis Shows Two Endemic Species Of North American Wolf Are Admixtures Of The Coyote And Gray Wolf”

In a recent article, vonHoldt and colleagues (1) use whole-genome sequence data to address the relationships and evolutionary origins of several North American canid taxa. The authors conclude that two taxa, the red wolf (Canis rufus) and the eastern wolf … read more

Whole-genome Sequence Analysis Shows That Two Endemic Species Of North American Wolf Are Admixtures Of The Coyote And Gray Wolf

Protection of populations comprising admixed genomes is a challenge under the Endangered Species Act (ESA), which is regarded as the most powerful species protection legislation ever passed in the United States but lacks specific provisions for hybrids. The eastern wolf … read more

Dna Profiles of the Eastern Canadian Wolf & the Red Wolf Provide Evidence For a Common Evolutionary History Independent of the Gray Wolf

The origin and taxonomy of the red wolf (Canis rufus) have been the subject of considerable debate and it has been suggested that this taxon was recently formed as a result of hybridization between the coyote and gray wolf. Like … read more
