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. Expand
Fluctuating Asymmetry: Measurement, Analysis, Patterns
With these words Darwin opened a brief paragraph citing observations antithetical to his supposition: anecdotal reports of the inheritance of characters missing from one side of the body. His initialExpand
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. Expand
Fluctuating Asymmetry Analyses Revisited
In spite of a decade of furious activity and an increasingly bewildering array of analytical methods, essential requirements for a robust study of fluctuating asymmetry have not changed: judiciousExpand
Genetic tagging of free-ranging black and brown bears
This work investigated the genetic variability of American black bears and brown bears in the Columbia River basin of British Columbia, Canada, and developed a method to obtain genetic samples from free-ranging bears, and established the background genetic variability using microsatellite genotyping at 9 loci using tissue and blood samples from captured bears.

Undesirable evolutionary consequences of trophy hunting
Declines in mean breeding values for weight and horn size have declined significantly over time in an evolutionary response to sport hunting of bighorn trophy rams, resulting in the production of smaller-horned, lighter rams and fewer trophies. Expand
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. Expand
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 inExpand
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.

Characterization of microsatellite loci in caribou Rangifer tarandus, and their use in other artiodactyls
Genetic analysis of caribou populations using microsatellites will be useful in addressing a number of population issues in this species, including the amount of genetic variation within and between populations, gene flow and herd identity. Expand
