| Abstract |
The biological status of the so-called 'Upland seal' has remained contentious ever since historical records described a distinct seal from the uplands of New Zealand's (NZ) remote sub-Antarctic islands. Subsequent genetic surveys of the NZ fur seal (Arctocephalus forsteri) detected two highly-divergent mtDNA clades, hypothesized to represent a post-sealing hybrid swarm between 'mainland' (Australia-NZ; A. forsteri) and sub-Antarctic (putative 'Upland'; A. snaresensis) lineages. We present ancient-DNA analyses of prehistoric mainland NZ and sub-Antarctic fur seals, revealing that both of these genetic lineages were already widely distributed across the region at the time of human arrival. These findings indicate that anthropogenic factors did not contribute to the admixture of these lineages, and cast doubt on the validity of the Upland seal. Human-mediated impacts on Arctocephalus genetic diversity are instead highlighted by a dramatic temporal haplotype frequency-shift due to genetic drift in heavily bottlenecked populations following the cessation of industrial-scale harvesting. These extinction-recolonisation dynamics add to a growing picture of human-mediated change in NZ's coastal and marine ecosystems. |

Attention Score in Context
This research output has an Altmetric Attention Score of 13. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 July 2018.
All research outputs
#2,776,630
of 25,543,275 outputs
Outputs from Molecular Phylogenetics & Evolution
#576
of 4,846 outputs
Outputs of similar age
#45,321
of 400,936 outputs
Outputs of similar age from Molecular Phylogenetics & Evolution
#9
of 63 outputs
Altmetric has tracked 25,543,275 research outputs across all sources so far. Compared to these this one has done well and is in the 89th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,846 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.5. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 400,936 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 88% of its contemporaries.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 87% of its contemporaries.
