Developing a genomic toolkit for the Antarctic fur seal: new insights into old questions
The genomic revolution has provided researchers with the opportunity to address broadreaching questions in ecology, evolution and conservation with greater power and precision than ever before. It is nowpossible to sequence genomes and produce high-resolution genomic marker datasets for practically...

The genomic revolution has provided researchers with the opportunity to address broadreaching questions in ecology, evolution and conservation with greater power and precision than ever before. It is nowpossible to sequence genomes and produce high-resolution genomic marker datasets for practically any species for which high quality DNA can be collected. There are a vast and expanding number of ways in which to develop genomic resources, but the gold standard is to create a permanent and diverse toolkit, as this is likely to provide the greatest power for addressing outstanding and timely questions long into the future. The Antarctic fur seal (Arctocephalus gazella) is an important polar predator and arguably one of the most intensely monitored pinniped species in the world. During the 18th and 19th century it was the target of large-scale commercial exploitation and despite having rebounded, worsening environmental conditions in the South Atlantic have meant that many fur seal populations are in decline again.
