Genomics detects population structure within and between ocean basins in a circumpolar seabird: The white‐chinned petrel
International audience The Southern Ocean represents a continuous stretch of circumpolar marine habitat,but the potential physical and ecological drivers of evolutionary genetic differentiationacross this vast ecosystem remain unclear. We tested for genetic structure acrossthe full circumpolar range...
