W olf individuals and populations have a striking variety of colours, ranging from white in arctic regions to black in some forested areas of western Canada and Alaska. The white colour in regions with ice and snow has long been suggested to be adaptive, concealing coloration to aid successful survival and predation. Similarly, some researchers have suggested that black colour is adaptive in forested areas with low light. In most mammals, black colour is the result of pigment type-switching to… Expand
Sequence analysis of three pigmentation genes in the Newfoundland population of Canis latrans links the Golden Retriever Mc1r variant to white coat color in coyotes
TLDR
It is speculated that natural selection, with or without a founder effect, may contribute to the observed frequency ofwhite coyotes in Newfoundland, as it has contributed to the high frequency of white bears, and of a domestic dog-derived CBD allele in gray wolves. Expand
Black coats in an admixed wolf × dog pack is melanism an indicator of hybridization in wolves?
TLDR
Admixture analyses of empirical and simulated genotypes indicate the parents of the pack originated through a single hybridization event at least two generations back, and suggest that the pack received the K locus deletion from dogs. Expand
Genetics and conservation of wolves Canis lupus in Europe
TLDR
The wolf Canis lupus, the most widespread of the four species of large carnivores in Europe, after centuries of population decline and eradication, is now recovering in many countries, and population structure and dynamics are efficiently monitored by non-invasive genetic methods. Expand
Spatial assessment of wolf-dog hybridization in a single breeding period
TLDR
This work considers that real-time population level assessments of hybridization provide a new perspective into the debate on wolf conservation, with particular focus on current management guidelines applied in wolf-dog hybridization events. Expand
Identifying footprints of selection in stocked brown trout populations: a spatio‐temporal approach
TLDR
This is the first study demonstrating footprints of selection in wild salmonid populations subject to spawning intrusion by farmed fish and no evidence for selection was found in the most strongly admixed population. Expand
Two decades of non-invasive genetic monitoring of the grey wolves recolonizing the Alps support very limited dog introgression
TLDR
The first genetic analysis of wolf-dog admixture in an area entirely recolonized, the northwestern Alps, is provided, with only 2 of them showing significant signs of admixture stemming from past interbreeding with dogs, followed by backcrossing. Expand
Living a dog’s life: a putative gray wolf in a feral dog group
TLDR
The most feasible explanation for this individual’s atypical behavior is that it is of hybrid origin (assumption based on phenotype), setting the basis for further investigation of the complex interaction between wolves, dogs and hybrids in the wild. Expand
Interface of Human/Wildlife Interactions: An Example of a Bold Coyote (Canis latrans) in Atlanta, GA, USA
There is arguably no other North American species that better illustrates the complexities of the human-wildlife interface than the coyote. In this study, a melanistic coyote in metropolitan Atlanta,Expand
Gene flow between wolf and shepherd dog populations in Georgia (Caucasus).
TLDR
The results of the study suggest that wolf-dog hybridization is a common event in the areas where large livestock guarding dogs are held in a traditional way, and that gene flow between dogs and gray wolves was an important force influencing gene pool of dogs for millennia since early domestication events. Expand
Warring brothers: The complex interactions between wolves (Canis lupus) and dogs (Canis familiaris) in a conservation context
TLDR
The review highlights how the wolf–dog relationship challenges human attempts to construct simple dichotomies between wild and domestic, or between nature and culture, and wolf conservation must adapt to this more complex reality. Expand

Color patterns among wolves in western North America
TLDR
Observations from wolf research, records from wildlife management agencies, and published accounts are compiled to document occurrence and distribution of pelt colors, and changes in individual wolves from black or gray to white. Expand
Molecular and Evolutionary History of Melanism in North American Gray Wolves
TLDR
It is shown that the melanistic K locus mutation in North American wolves derives from past hybridization with domestic dogs, has risen to high frequency in forested habitats, and exhibits a molecular signature of positive selection. Expand
Differentiation of tundra/taiga and boreal coniferous forest wolves: genetics, coat colour and association with migratory caribou
TLDR
Findings show that substantial genetic and phenotypic differentiation in highly mobile mammals can be caused by prey–habitat specialization rather than distance or topographic barriers, and highlights the need to preserve migratory populations. Expand
Agouti sequence polymorphisms in coyotes, wolves and dogs suggest hybridization.
TLDR
It is concluded that these were coyote-dog hybrids because both were heterozygous for 2 mutations causing fawn coat color in dogs, and a relatively common polymorphism in the 3' UTR sequence that could be used for population studies. Expand
Molecular Genetics and Evolution of Melanism in the Cat Family
TLDR
The inferred multiple origins and independent historical elevation in population frequency of felid melanistic mutations suggest the occurrence of adaptive evolution of this visible phenotype in a group of related free-ranging species. Expand
The genealogy and genetic viability of reintroduced Yellowstone grey wolves
TLDR
Simulations showed that the Yellowstone population has levels of genetic variation similar to that of a population managed for high variation and low inbreeding, and greater than that expected for random breeding within packs or across the entire breeding pool. Expand
Dewclaws in wolves as evidence of admixed ancestry with dogs
TLDR
It is concluded that dewclawed wolves, when present, are a clue of hybridization with dogs, and patterns of dewclaw inheritance in wolf–dog hybrids and backcrosses have not been ascertained. Expand
The genetic basis of adaptive melanism in pocket mice
TLDR
The molecular changes underlying adaptive coat color variation in a natural population of rock pocket mice, Chaetodipus intermedius, are described and four mutations in the melanocortin-1-receptor gene seem to be responsible for adaptive melanism in one population of lava-dwelling pocket mice.

TLDR
The many millions of North American bison in the mid-19th century were reduced to near extinction by the middle 1880s, which resulted in the present-day plains bison population being descended from less than 100 founders. Expand

TLDR
Results indicate that introgressive hybridization can be locally pervasive, and that conservation plans should be implemented to preserve the integrity of the gene pools of wild populations, as well as evaluating risks of outbreeding depression. Expand
