High-resolution, male-inherited Y-chromosomal markers are a useful tool
for population genetic analyses of wildlife species, but to date have only
been applied in this context to relatively few species besides humans.
Using nine Y-chromosomal STR and three Y-chromosomal single nucleotide
polymorphism markers (Y-SNPs), we studied whether male gene flow was
important for the recent recovery of the brown bear (Ursus arctos) in
Northern Europe, where the species declined dramatically in numbers and
geographic distribution during the last centuries but is expanding now. We
found 36 haplotypes in 443 male extant brown bears from Sweden, Norway,
Finland and Northwestern Russia. In 14 individuals from southern Norway
from 1780 to 1920, we found two Y chromosome haplotypes present in the
extant population as well as four Y chromosome haplotypes not present
among the modern samples. Our results suggested major differences in
genetic connectivity, diversity, and structure between the eastern and the
western populations in Northern Europe. In the west, our results indicated
that the recovered population originated from only four male lineages,
displaying pronounced spatial structuring suggestive of large-scale
population size increase under limited male gene flow within the western
subpopulation. In the east, we found a contrasting pattern, with high
haplotype diversity and admixture. This first population genetic analysis
of male brown bears shows conclusively that male gene flow was not the
main force of population recovery.
Y-STR data, Y-SNP data and geographic location of brown bears in Northern
EuropeThis data file contains sample names (indicating the sampling
location used to group samples for the analyses) and the respective Y-STR
and Y-SNP haplotypic profile for each individual as well as the assigned Y
chromosomal haplotype. In addition, each sample is given the samling
country and the sampling coordinates in decimal format.Datafile_DRYAD.xlsx
