Genome sequence, comparative analysis and haplotype structure of the domestic dog
A high-quality draft genome sequence of the domestic dog is reported, together with a dense map of single nucleotide polymorphisms (SNPs) across breeds, to shed light on the structure and evolution of genomes and genes.
Transgressive segregation, adaptation and speciation
Credence is lent to the view that hybridization may provide the raw material for rapid adaptation and provide a simple explanation for niche divergence and phenotypic novelty often associated with hybrid lineages.
SNPs in ecology, evolution and conservation
Multigene phylogeny of the Mustelidae: Resolving relationships, tempo and biogeographic history of a mammalian adaptive radiation
Using Bayesian dating techniques, phylogenetic and dating analyses suggest that mustelid diversification may have been spurred by a combination of faunal turnover events and diversification at lower trophic levels, ultimately caused by climatically driven environmental changes.
Multiple and ancient origins of the domestic dog.
Sequences from both dogs and wolves showed considerable diversity and supported the hypothesis that wolves were the ancestors of dogs, suggesting that dogs originated more than 100,000 years before the present.

Genotyping coyote faeces systematically collected in the Santa Monica Mountains near Los Angeles, California, exemplify a general, non–invasive method to census large mammals and shows that home range use, paternity and kinship can be inferred from the distribution and relatedness patterns of faecal genotypes.
Mitochondrial DNA phylogeography and population history of the grey wolf Canis lupus
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.
High MHC diversity maintained by balancing selection in an otherwise genetically monomorphic mammal.

It is shown by simulation that genetic monomorphism at neutral loci and high MHC variation could arise only through an extreme population bottleneck of <10 individuals, approximately 10-20 generations ago, accompanied by unprecedented selection coefficients of >0.5 on MHC loci.
Genome-wide SNP and haplotype analyses reveal a rich history underlying dog domestication
It is shown that dog breeds share a higher proportion of multi-locus haplotypes unique to grey wolves from the Middle East, indicating that they are a dominant source of genetic diversity for dogs rather than wolves from east Asia, as suggested by mitochondrial DNA sequence data.
Effects of Urbanization and Habitat Fragmentation on Bobcats and Coyotes in Southern California
Abstract: Urbanization and habitat fragmentation are major threats to wildlife populations, especially mammalian carnivores. We studied the ecology and behavior of bobcats ( Lynx rufus ) and…
