Defining subpopulations using genetics has traditionally used data from microsatellite
markers to investigate population structure; however, single‐nucleotide polymorphisms …

The primary habitat for polar bears is sea ice, yet unlike most of the high Arctic, Hudson Bay
undergoes a summer ice-free period that forces all bears ashore until ice forms again in fall …

Identifying biologically meaningful populations is essential to the conservation and
management of at‐risk species. Natural populations can be delineated using a variety of …

Predicting the consequences of environmental changes, including human‐mediated climate
change on species, requires that we quantify range‐wide patterns of genetic diversity and …

Single‐nucleotide polymorphisms (SNP s) offer numerous advantages over anonymous
markers such as microsatellites, including improved estimation of population parameters …

As global warming accelerates the melting of A rctic sea ice, polar bears (U rsus maritimus)
must adapt to a rapidly changing landscape. This process will necessarily alter the species …

Changes in sea-ice dynamics are affecting polar bears Ursus maritimus across their
circumpolar range, which highlights the importance of periodic demographic assessments to …

A summary of existing population genetics literature is presented for polar bears (Ursus
maritimus) and interpreted in the context of the species' life-history characteristics and …

A morphometric study was conducted on four skull traits of 37 male and 18 female adult East
Greenland polar bears (Ursus maritimus) collected 1892–1968, and on 54 male and 44 …

Polar bears (Ursus maritimus) are unique among bears in that they are adapted to the Arctic
sea ice environment. Genetic data are useful for understanding their evolution and can …
