Mitochondrial DNA phylogeography and population history of the grey wolf Canis lupus
TLDR
The results suggest that fluctuating population sizes during the late Pleistocene have left a genetic signature on levels of variation in both species, and a statistical parsimony analysis indicates local genetic structure that suggests recent restricted gene flow.
Ancient DNA Evidence for Old World Origin of New World Dogs
Mitochondrial DNA sequences isolated from ancient dog remains from Latin America and Alaska showed that native American dogs originated from multiple Old World lineages of dogs that accompanied late
Widespread origins of domestic horse lineages.
Domestication entails control of wild species and is generally regarded as a complex process confined to a restricted area and culture. Previous DNA sequence analyses of several domestic species have
Complete Mitochondrial Genomes of Ancient Canids Suggest a European Origin of Domestic Dogs
TLDR
The findings imply that domestic dogs are the culmination of a process that initiated with European hunter-gatherers and the canids with whom they interacted, and molecular dating suggests an onset of domestication there 18,800 to 32,100 years ago.
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.
FAST TRACK: Legacy lost: genetic variability and population size of extirpated US grey wolves (Canis lupus)
TLDR
Analysis of mitochondrial DNA sequences of 34 pre‐extermination wolves found that they had more than twice the diversity of their modern conspecifics, implying a historic population size of several hundred thousand wolves in the western cUS and Mexico, and a much wider geographical mandate for the reintroduction of Mexican wolves than currently planned.
Population genetics of ice age brown bears.
The Pleistocene was a dynamic period for Holarctic mammal species, complicated by episodes of glaciation, local extinctions, and intercontinental migration. The genetic consequences of these events
Nuclear Genomic Sequences Reveal that Polar Bears Are an Old and Distinct Bear Lineage
TLDR
A high-resolution data set from multiple independent loci across the nuclear genomes of a broad sample of polar, brown, and black bears reveals polar bears as a sister lineage to all brown bears, and confirms previous suggestions that polar bears carry introgressed brown bear mitochondrial DNA due to past hybridization.
Species-specific responses of Late Quaternary megafauna to climate and humans
TLDR
It is shown that climate has been a major driver of population change over the past 50,000 years, however, each species responds differently to the effects of climatic shifts, habitat redistribution and human encroachment.
