Previous phylogeographical and palaeontological studies on the biota of northern North
America have revealed a complex scenario of glacial survival in multiple refugia and …

Abstract Aim Late Pleistocene ice sheets are thought to have covered most of western
Canada, including all of British Columbia (BC). We examine patterns of genetic variation in …

Aim We examine several hypotheses emerging from biogeographical and fossil records
regarding glacial refugia of a southern thermophilic plant species. Specifically, we …

The ranges of arctic–alpine species have shifted extensively with Pleistocene climate
changes and glaciations. Using sequence data from the trnH‐psbA and trnT‐trnL chloroplast …

The glacial episodes of the Quaternary (2.6 million years ago–present) were a major factor
in shaping the present-day distributions of extant flora and fauna, with expansions and …

PREMISE OF THE STUDY: Glacial cycles have influenced the genetic structure of many
species. In addition to facilitating genetic divergence, isolation in multiple glacial refugia may …

Hypotheses of tree survival in refugia or long-distance postglacial migration can be
disentangled combining genetic polymorphisms and ecological niche modeling. This is …

Glaciations especially the Pleistocene glaciations have important effects on the patterns of
spatial distribution and genetic structure of organisms. Glacial refugium is the area where …

Regional phylogeographical studies involving co‐distributed animal and plant species have
been conducted for several areas, most notably for Europe and the Pacific Northwest of …

Glacial cycles have played a dominant role in shaping the genetic structure and distribution
of biota in northwestern North America. The two major ice age refugia of Beringia and the …
