| north american transmission of hemosporidian parasites in the swainson's thrush (catharus ustulatus), a migratory songbird. | the geographic structuring of parasite communities across the range of a single host species can illuminate patterns of host-population connectivity. to determine the location of parasite transmission in a neotropical migrant bird species, we sampled adult and hatch-year (hy) birds across the breeding and wintering range of the swainson's thrush (swth), an abundant passerine with a migratory divide. we examined the phylogenetic relationships among cytochrome b lineages of the avian blood parasit ... | 2013 | 23030456 |
