| interspecific variability of prevalence in blood parasites of adult passerine birds during the breeding season in alaska. | blood parasite prevalence based on microscopic examination of stained blood smears was determined in adults of 11 passerine bird species sampled during their breeding season (may and june 1997-98) in interior alaska (usa). these species included primarily nearctic migratory species such as the dark-eyed junco (junco hyemalis) and neotropical migratory species such as the blackpoll warbler (dendroica striata), alder flycatcher (empidonax alnorum), swainson's thrush (catharus ustulatus), northern ... | 2001 | 11272501 |
| old divergences in a boreal bird supports long-term survival through the ice ages. | unlike northern europe and most of northern north america, the eastern palearctic and the northwesternmost tip of north america are believed to have been almost unglaciated during the quarternary glacial periods. this could have facilitated long-term survival of many organisms in that area. to evaluate this, we studied the phylogeography in east asia and alaska of a boreal migratory passerine bird, the arctic warbler phylloscopus borealis, and compared our results with published data on especial ... | 2010 | 20128930 |
