Multigenerational pedigrees have been developed for free-ranging populations of many species, are frequently used to describe mating systems, and are used in studies of quantitative genetics. Here, we document the development of a 4449-individual pedigree for the Western Hudson Bay subpopulation of polar bears (Ursus maritimus), created from relationships inferred from field and genetic data collected over six generations of bears sampled between 1966 and 2011. Microsatellite genotypes for 22… Expand

Figures and Tables from this paper

Incidence of Multiple Paternity and Inbreeding in High-Density Brown Bear Populations on the Shiretoko Peninsula, Hokkaido, Japan.
TLDR
The results suggest that male-biased natal dispersal effectively limits mating between closely related individuals (aside from fathers and daughters) in brown bears, similar to a Scandinavian population. Expand
Heritability of body size in the polar bears of Western Hudson Bay
TLDR
A 4449‐individual pedigree and an array of 5,433 single nucleotide polymorphisms (SNPs) to provide the first quantitative genetic study of polar bears and suggested that variation in body length was associated with genes in the regulatory cascade of cyclin expression, which has previously been associated with body size in mice.

Pedigree reconstruction reveals large scale movement patterns and population dynamics of wolverines (Gulo gulo) across Fennoscandia
Dispersal is a biological imperative for many species, facilitating gene flow and influencing population dynamics. Modern landscapes are increasingly fragmented, leaving species that rely onExpand
Assessing polar bear (Ursus maritimus) population structure in the Hudson Bay region using SNPs
TLDR
Using SNPs to detect fine‐scale population structure in polar bears from the Hudson Bay region and compared the results to the current designations demonstrating the value of using SNPs for fine-scale population delineation in polar Bears. Expand
Variance in lifetime reproductive success of male polar bears
TLDR
The results support a growing body of evidence that suggests that male-biased size dimorphism and polygynous mating systems need not be associated with high variance in male mating and/or reproductive success. Expand
Quantitative analysis of connectivity in populations of a semi-aquatic mammal using kinship categories and network assortativity.
TLDR
K kinship networks were built and a method based on the assortativity coefficient, which measures the proportion between observed and expected kinship relationships across a barrier, enabled us to infer that the most important barrier in the area was the watershed divide between the rivers, followed by a dam on one of the rivers.

TLDR
Amyoplasia, a specific nongenetic form of arthrogryposis, appears to occur in spontaneous MZ twinning and may be related to twin–twin transfusion. Expand

TLDR
The mating system of polar bears in the Barents Sea appears to be promiscuous, usually with a single successful father siring full siblings within a year, but with consecutive litters of a mother being fathe... Expand

TLDR
In outbred diploid populations, the pedigree approach is superior to analyses based on marker-based pairwise estimators of coancestry, and even where only imprecise pedigrees are available it is possible to estimate the consequences of imprecision for the questions of interest. Expand
Genetic linkage map of a wild genome: genomic structure, recombination and sexual dimorphism in bighorn sheep
TLDR
A first-generation bighorn sheep linkage map is developed that will facilitate future studies of the genetic architecture of trait variation in this species and suggests that domestication may have played a role in altering patterns of heterochiasmy. Expand
Estimation of pairwise relatedness with molecular markers.
TLDR
Two examples are given in which the new estimators are applied to natural populations, one that reveals isolation-by-distance in an annual plant and the other that suggests a genetic basis for a coat color polymorphism in bears. Expand

TLDR
The results provide novel insights into the reproductive ecology of fur seals and also support an earlier study showing that molecular genetic analysis can provide an effective means of validating field observations of pinniped twins. Expand

TLDR
Evidence supports the hypothesis that inbreeding avoidance is achieved by means of male‐biased dispersal but also indicates that competition (for mates or resources) modifies dispersal patterns. Expand
Single nucleotide polymorphism-based dispersal estimates using noninvasive sampling
TLDR
The results illustrate the potential of using a combination of noninvasively collected samples at high resolution and specialized SNPs for pedigree-based dispersal models and are in agreement with the previously identified pattern of male-biased dispersal. Expand

An attempt to map quantitative trait loci for birth weight in an unmanipulated, wild population of red deer (Cervus elaphus) is described, the first time that a QTL for any trait has been mapped in a wild mammal population. Expand
