Molecular phylogeny of the Arctoidea (Carnivora): effect of missing data on supertree and supermatrix analyses of multiple gene data sets.
Phylogenetic relationships of 79 caniform carnivores were addressed based on four nuclear sequence-tagged sites (STS) and one nuclear exon, IRBP, using both supertree and supermatrix analyses. We… Expand
Ancient Hybridization and an Irish Origin for the Modern Polar Bear Matriline
BACKGROUND Polar bears (Ursus maritimus) are among those species most susceptible to the rapidly changing arctic climate, and their survival is of global concern. Despite this, little is known about… Expand
Genomic Evidence for Island Population Conversion Resolves Conflicting Theories of Polar Bear Evolution
Despite extensive genetic analysis, the evolutionary relationship between polar bears (Ursus maritimus) and brown bears (U. arctos) remains unclear. The two most recent comprehensive reports indicate… Expand
Multiple fossil calibrations, nuclear loci and mitochondrial genomes provide new insight into biogeography and divergence timing for true seals (Phocidae, Pinnipedia)
Aim To better understand the historical biogeography of the true seals, Phocidae, by combining nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) in a divergence time analysis using multiple fossil… Expand
Ecological Consequences of Sea-Ice Decline
After a decade with nine of the lowest arctic sea-ice minima on record, including the historically low minimum in 2012, we synthesize recent developments in the study of ecological responses to… Expand

- 22 June 2012
Steamer ducks (Tachyeres) comprise four species, three of which are flightless. The flightless species are believed to have diverged from a flying common ancestor during the Late Pleistocene;… Expand
Multiple markers and multiple individuals refine true seal phylogeny and bring molecules and morphology back in line
Despite decades of study, some aspects of Phocidae (Pinnipedia, Carnivora) phylogeny still remain unresolved. Using the largest novel dataset to date, including all extant phocids and comprising 15… Expand
Novel phylogeny of the raccoon family (Procyonidae: Carnivora) based on nuclear and mitochondrial DNA evidence.
The raccoon family, Procyonidae, is the least studied of the caniform (dog-like) carnivore families. Often represented by two or three species in carnivore phylogenetic studies, to date, no molecular… Expand
Setting up an ancient DNA laboratory.

Entering into the world of ancient DNA research is nontrivial. Because the DNA in most ancient specimens is degraded to some extent, the potential for contamination of ancient samples and DNA… Expand
Genomic evidence of geographically widespread effect of gene flow from polar bears into brown bears
Polar bears are an arctic, marine adapted species that is closely related to brown bears. Genome analyses have shown that polar bears are distinct and genetically homogeneous in comparison to brown… Expand
