South polar skua (Catharacta maccormicki) as biovectors for long-range transport of persistent organic pollutants to Antarctica
Migratory bird species may serve as vectors of contaminants to Antarctica through the local deposition of guano, egg abandonment, or mortality. To further investigate this chemical input pathway, we examined the contaminant burdens and profiles of the migratory South polar skua (Catharacta maccormic...
