Figure 1

Phylogeny of seabird species and hemoparasite infections. The clasification includes species for which at least 15 individuals have been sampled for blood parasites, using blood smears or molecular methods. Colour marked are those species which were found to be infected with Hepatozoon (blue), Plasmodium (red) and Haemoproteus (yellow). The apparent phylogenetic clustering was, however, not statistically significant.
