Hemosporidian blood parasites in seabirds—a comparative genetic study of species from Antarctic to tropical habitats
Whereas some bird species are heavily affected by blood parasites in the wild, others reportedly are not. Seabirds, in particular, are often free from blood parasites, even in the presence of potential vectors. By means of polymerase chain reaction, we amplified a DNA fragment from the cytochrome b...

Whereas some bird species are heavily affected by blood parasites in the wild, others reportedly are not.
