We studied genetic structure in polar bear (Ursus maritimus) populations by typing a sample of 473 individuals spanning the species distribution at 16 highly variable microsatellite loci. No genetic discontinuities were found that would be consistent with evolutionarily significant periods of isolation between groups. Direct comparison of movement data and genetic data from the Canadian Arctic revealed a highly significant correlation. Genetic data generally supported existing population… 

Genetic structure among continental and island populations of gyrfalcons

It is inferred that the observed microsatellite population genetic structure has developed since the last glacial maximum, consistent with gyrfalcons having expanded rapidly from a single glacial‐age refugium to their current circumpolar distribution.

Genetic structure in large, continuous mammal populations: the example of brown bears in northwestern Eurasia

Data on population structure, genetic diversity and gene flow in a brown bear population inhabiting the large territory of northwestern Eurasia indicates a complex pattern where a fraction of the population exhibits large‐scale gene flow that is unparalleled by other wild mammals studied to date.

Genetic diversity and differentiation of Kermode bear populations

Kermodism was established and is maintained in populations by a combination of genetic isolation and somewhat reduced population sizes in insular habitat, with the possible contribution of selective pressure and/or nonrandom mating.

Implications of the Circumpolar Genetic Structure of Polar Bears for Their Conservation in a Rapidly Warming Arctic

An expansive analysis of polar bear (Ursus maritimus) circumpolar genetic variation during the last two decades of decline in their sea-ice habitat seeks to evaluate whether their genetic diversity and structure have changed, how their current genetic patterns compare with past patterns, and how genetic demography changed with ancient fluctuations in climate.


The analysis of the Florida Mottled Duck population indicated high levels of heterozygosity and no evidence of genetic subdivision among breeding units, and the objective was to identify nuclear DNA-based markers for Mottling Ducks and determine levels of subdivision among populations in Florida.

Canadian polar bear population structure using genome‐wide markers

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

Genetic structure of North American wolverine (Gulo gulo) populations

It is suggested that reductions in this species’ range may have led to population fragmentation in the extreme reaches of its southern distribution and the continued reduction of suitable habitat for this species may lead to more populations becoming isolated remnants of a larger distribution of northern wolverines, as documented in other North American carnivore species.

Population genetic structure of North American thinhorn sheep (Ovis dalli)

The spatial genetic structure of thinhorn sheep populations representing both subspecies is investigated by genotyping individuals from across the species range at 12 variable microsatellite loci and shows evidence for genetic differences between the two currently recognized thinhorn subspecies.

Arctic fox Vulpes lagopus population structure : circumpolar patterns and processes

Movement is a prominent process shaping genetic population structure. In many northern mammal species, population structure is formed by geographic distance, geographical barriers and various

Gene flow on the ice: genetic differentiation among Adélie penguin colonies around Antarctica

Data from seven microsatellite DNA loci for 442 individuals from 13 locations around the Antarctic continent reveal a lack of genetic differentiation between Adélie penguin colonies around the Antarctica continent, despite substantial levels of genetic variation.



Microsatellite analysis of population structure in Canadian polar bears

Using eight hypervariable microsatellite loci to study the genetic relationships between four Canadian polar bear populations indicates that gene flow between local populations is restricted despite the long‐distance seasonal movements undertaken by polar bears.

Population genetic studies of the polar bear ( Ursus maritimus ): A summary of available data and interpretation of results

A summary of existing population genetics literature is presented for polar bears and interpreted in the context of the species' life-history characteristics and regional heterogeneity in environmental regimes and movement patterns, which suggest some degree of spatial structuring.

An empirical evaluation of genetic distance statistics using microsatellite data from bear (Ursidae) populations.

A large microsatellite data set from three species of bear was used to empirically test the performance of six genetic distance measures in resolving relationships at a variety of scales, finding that linearity was lost for each of the statistics.

Microsatellite analysis of genetic variation in black bear populations

The development of microsatellite analysis in bears and its use in assessing interpopulation differences in genetic variation in black bears from three Canadian National Parks are described.

Gene flow between insular, coastal and interior populations of brown bears in Alaska

The ‘big brown bears' of coastal Alaska were found to be part of the continuous continental distribution of brown bears, and not genetically isolated from the physically smaller ‘grizzly bears’ of the interior, and the bears of the Kodiak Archipelago appear to have experienced little or no genetic exchange with continental populations in recent generations.

Patterns of differentiation and hybridization in North American wolflike canids, revealed by analysis of microsatellite loci.

It is demonstrated that wolves and coyotes do not show a pattern of genetic differentiation by distance, and gray wolves show significant subdivision that may be either due to drift in past Ice Age refugia populations or a result of other causes.

Low protein variability and genetic similarity between populations of the polar bear (Ursus maritimus)

The degree of protein and enzyme variation in the polar bear was observed to be relatively low and starch gel electrophoresis revealed variation of an unidentified serum protein, which indicates a closer connection between bears in Alaska and Canada compared to those in Greenland and Svalbard.

Noninvasive genetic tracking of the endangered Pyrenean brown bear population

Comprehensive knowledge of endangered small populations of mammals can be obtained using noninvasive genetic sampling and it is suggested that managers consider population augmentation using only females to preserve the remaining Pyrenean gene pool and increase genetic diversity.

High resolution of human evolutionary trees with polymorphic microsatellites

It is shown that polymorphic microsatellites (primarily CA repeats) allow trees of human individuals to be constructed that reflect their geographic origin with remarkable accuracy by the analysis of a large number of loci for each individual, in spite of the small variations in allele frequencies existing between populations.

Distribution and Abundance of Canadian Polar Bear Populations: A Management Perspective

Seasonal fidelity to relatively local areas and natural obstacles to movements allow the range of polar bears ( Ursus maritimus ) in Canada to be divided into 12 relatively distinct populations.
