Diversity among assemblages of mammalian hosts and parasites in northern terrestrial
ecosystems was structured by a deep history of biotic and abiotic change that overlies a …

We provide the first comparative multispecies analysis of spatial genetic structure and
diversity in the circumpolar Arctic using a common strategy for sampling and genetic …

The response of Arctic organisms and their parasites to dramatic fluctuations in climate
during the Pleistocene has direct implications for predicting the impact of current climate …

Beringia is the region spanning eastern Asia and northwestern North America that remained
ice-free during the full glacial events of the Pleistocene. Numerous questions persist …

Abstract Aim Eric Hultén hypothesized that most arctic plants initially radiated from Beringia
in the Late Tertiary and persisted in this unglaciated area during the Pleistocene glaciations …

A novel shrew was discovered recently in Alaska and described based on morphological
characters as Sorex yukonicus. This species is closely allied to Sorex minutissimus, a …

Fossil evidence shows that populations of species that currently inhabit arctic and boreal
regions were not isolated in refugia during glacial periods, but instead maintained …

Phylogeographical investigations of arctic organisms provide spatial and temporal
frameworks for interpreting the role of climate change on biotic diversity in high‐latitude …

Little is known about the possible influence that past glacial events have had on the
phylogeography and population structure of avian predators in the Arctic and sub‐Arctic. In …

Glacial cycles in the late Pleistocene played a dominant role in sculpting the evolutionary
histories of many high-latitude organisms. The refugial hypothesis argues that populations …
