Historical and ecological determinants of genetic structure in arctic canids
TLDR
Results presented here suggest that, through its influence on sea ice, vegetation, prey dynamics and distribution, continued arctic climate change may have effects as dramatic as those of the Pleistocene on the genetic structure of arctic canid species.
Prey specialization may influence patterns of gene flow in wolves of the Canadian Northwest
TLDR
Results indicate that wolf gene flow is reduced significantly across the Mackenzie River, most likely due to the north–south migration patterns of the barren‐ground caribou herds that flank it, and the possibility that these barriers reflect prey specialization by wolves in different regions.
DLA-DRB1, DQA1, and DQB1 alleles and haplotypes in North American Gray Wolves.
TLDR
The wolves studied had relatively few dog DLA alleles and may therefore represent a remnant population descended from Asian wolves, suggesting that the wolf ancestors of Asian and European dogs may have had different gene pools, currently reflected in the D LA alleles present in dog breeds.
Development and characterization of microsatellite loci from lynx (Lynx canadensis), and their use in other felids
Northwest passages: conservation genetics of Arctic Island wolves
TLDR
It is suggested that Arctic Island wolves function as a metapopulation, supported by periodic migration from mainland populations, occurring primarily through two corridors: Baffin Island in the Eastern Arctic, and Victoria Island inThe Western Arctic.
Age-dependent genetic structure of arctic foxes in Svalbard
TLDR
Genotypes at 12 microsatellite loci for 561 arctic foxes trapped in the high-arctic archipelago Svalbard are analyzed and indicate a possible kin structure among adult females, suggesting natal philopatry, but further investigations will be needed to reach firm conclusions concerning kin structure.
Pulses of movement across the sea ice: population connectivity and temporal genetic structure in the arctic fox
TLDR
The lemming cycle is likely an important factor shaping Arctic fox movement across sea ice and the subsequent population genetic structure, but is also likely to influence local adaptation to the coastal habitat and the prevalence of diseases.
Arctic fox Vulpes lagopus population structure : circumpolar patterns and processes
Movement is a prominent process shaping genetic population structure. In many northern mammal species, population structure is formed by geographic distance, geographical barriers and various…
GENOTYPING OF PSEUDOHERMAPHRODITE POLAR BEARS IN NUNAVUT AND ADVANCES IN DNA SEXING TECHNIQUES
TLDR
Ten of 11 morphologically abnormal individuals may possess no genuine male-specific DNA and nongenetic mechanisms such as maternal tumors, freemartinism, or endocrinological effects of environmental contaminants may also influence the development of the female pseudohermaphrodite phenotype in Nunavut polar bears.
Free love in the far north: plural breeding and polyandry of arctic foxes (Alopex lagopus) on Bylot Island, Nunavut
TLDR
Reproductive output in arctic foxes is closely tied to the productivity of their habitat in a given year; this data supports the hypothesis that abundant resources at o...
