| Abstract: | Morphometric analysis of 282 skulls of the brown bear Ursus arctos from the Far Eastern part of the range was carried out. The presence of two morphological clusters for both males and females is shown. Samples from two clusters were compared with their geographical location and subspecies. It was found that one cluster or another had no specific reference to the particular region or subspecies of a particular cluster, only the superiority of one over the other in a cluster of different subspecies and regions was changed. A comparison with the spread of brown bear genetic lines in the Far East of Russia is made. It was noted that the precise distribution of a particular cluster to a specific genetic line of haplotypes was not found. |
