GENECLASS2: a software for genetic assignment and first-generation migrant detection.
TLDR
GENECLASS2 is a software that computes various genetic assignment criteria to assign or exclude reference populations as the origin of diploid or haploid individuals, as well as of groups of individuals, on the basis of multilocus genotype data, for the specific task of first-generation migrant detection.
Genetic assignment methods for the direct, real‐time estimation of migration rate: a simulation‐based exploration of accuracy and power
TLDR
Simulated data sets were used to test the power and accuracy of Monte Carlo resampling methods in generating statistical thresholds for identifying F0 immigrants in populations with ongoing gene flow, and hence for providing direct, real‐time estimates of migration rates.
Microsatellite analysis of population structure in Canadian polar bears
TLDR
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.
Microsatellite analysis of genetic variation in black bear populations
TLDR
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.
Computer Note GENECLASS 2 : A Software for Genetic Assignment and First-Generation Migrant Detection
TLDR
GENECLASS2 is a software that computes various genetic assignment criteria to assign or exclude reference populations as the origin of diploid or haploid individuals, as well as of groups of individuals, on the basis of multilocus genotype data, for the specific task of first-generation migrant detection.
An empirical evaluation of genetic distance statistics using microsatellite data from bear (Ursidae) populations.
TLDR
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.
Gene flow between insular, coastal and interior populations of brown bears in Alaska
TLDR
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.
Variation in Genetic Diversity across the Range of North American Brown Bears
Understanding the factors that influence the rate at which natural populations lose genetic diversity is a central aspect of conservation genetics because of the importance of genetic diversity in…
Genetic structure of the world’s polar bear populations
TLDR
It is suggested that the observed pattern of genetic discontinuities has developed in response to differences in the seasonal distribution and pattern of sea ice habitat and the effects of these differences on the distribution and abundance of seals.
Microsatellite analysis of paternity and reproduction in Arctic grizzly bears.
TLDR
Analysis of microsatellite loci of 30 grizzly bear family groups demonstrate that each cub in a litter can be sired independently, and estimates of maximum reproductive success for males are derived from an Arctic population in northwestern Alaska that is minimally affected by human activities.
