| widespread and structured distributions of blood parasite haplotypes across a migratory divide of the swainson's thrush (catharus ustulatus). | we examined the phylogenetic distribution of cytochrome b haplotypes of the avian blood parasite genera haemoproteus and plasmodium across the migratory divide of the swainson's thrush (catharus ustulatus) in british columbia, canada. from 87 host individuals, we identified 8 parasite haplotypes; 4 of plasmodium and 4 of haemoproteus. six haplotypes were novel; 1 haemoproteus haplotype was identical to h. majoris found in the blue tit (parus caeruleus) in sweden, and another halotype was identic ... | 2007 | 18314697 |
