Fig. 6.

Partial maximum likelihood phylogenetic tree depicting inferred relationship among Haemoproteus mitochondrial DNA cytochrome b haplotypes obtained from waterfowl. Branch tips are labeled with GenBank accession number, lineage name, host taxon, and sample location (U.S. state and/or country). Haplotypes identified in northern pintails in Alaska and California as part of this study are indicated in bold font. A summary of continent of origin for parasite haplotypes comprising major clades is provided to the right of brackets. Bootstrap support values >70 are shown.
