Isotopic tracking of carnivore palaeoecology is a relatively new approach that yielded
important results for the study of the non-analogue mammoth steppe biome. After describing …

What are the models used in phylogenetic analysis and what exactly is involved in Bayesian
evolutionary analysis using Markov chain Monte Carlo (MCMC) methods? How can you …

Clovis groups in Late Pleistocene North America occasionally hunted several now extinct
large mammals. But whether their hunting drove 37 genera of animals to extinction has been …

The mechanisms of Late Pleistocene megafauna extinctions remain fiercely contested, with
human impact or climate change cited as principal drivers. We compared ancient DNA and …

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 …

Understanding the population dynamics of megafauna that inhabited the mammoth steppe
provides insights into the causes of extinctions during both the terminal Pleistocene and …

With a range that covered most of northern Eurasia and parts of North America, the cave lion
(Panthera spelaea) was one of the most widespread carnivores of the Late Pleistocene …

We provide an expansive analysis of polar bear (Ursus maritimus) circumpolar genetic
variation during the last two decades of decline in their sea-ice habitat. We sought to …

Molecular genetic analyses present powerful tools for elucidating demographic and
biogeographic histories of taxa. Here we present genetic evidence showing a dynamic …

Résumé In this report, I review recent molecular studies dealing with the origin and evolution
of polar bears (Ursus maritimus), with special emphasis on their relationships with brown …
