| 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 |
| mercury concentrations in bicknell's thrush and other insectivorous passerines in montane forests of northeastern north america. | anthropogenic input of mercury (hg) into the environment has elevated risk to fish and wildlife, particularly in northeastern north america. investigations into the transfer and fate of hg have focused on inhabitants of freshwater aquatic ecosystems, as these are the habitats at greatest risk for methylmercury (mehg) biomagnification. deviating from such an approach, we documented mehg availability in a terrestrial montane ecosystem using a suite of insectivorous passerines. intensive and extens ... | 2005 | 15931968 |
