Migratory birds may carry fewer parasites between islands than expected, DNA shows

Article excerpt

A new study published in the Journal of Helminthology by researchers from the Estonian University of Life Sciences and the Swedish University of Agricultural Sciences, together with collaborators from Greenland and the Faroe Islands, has revealed surprisingly limited dispersal of Diplostomum parasites across North Atlantic islands. The findings challenge the common assumption that migratory birds readily transport parasites over large geographic distances.
