Microhabitat preference and coexistence of ectoparasitic arthropods on Alaskan seabirds
The population structure and distribution patterns of ectoparasitic arthropods on four species of Alaskan seabirds (common murre (Uria aalge), thick-billed murre (Uria lomvia), black-legged kittiwake (Rissa tridactyla), and red-legged kittiwake (Rissa brevirostris)) were studied and interspecific in...

The population structure and distribution patterns of ectoparasitic arthropods on four species of Alaskan seabirds (common murre (Uria aalge), thick-billed murre (Uria lomvia), black-legged kittiwake (Rissa tridactyla), and red-legged kittiwake (Rissa brevirostris)) were studied and interspecific interactions were examined. In most ectoparasite populations on murres and kittiwakes, females predominated. This pattern may be attributable to differences in activity, behavior, and mortality between the sexes of the ectoparasites. Except for feather mites, adults of most ectoparasites were less abundant than immatures. The extremely high relative abundance of immature ticks was probably due to the high fecundity of these organisms and predation pressure. Distribution patterns of adults differed significantly from those of immatures in most louse and tick populations. Populations of lice (Quadraceps obliquus (Mjöberg), Quadraceps ornatus (Grube)) and ticks (Ixodes uriae White) on murres and kittiwakes were highly clumped. The degree of clumping was lower among ectoparasites on murres than among those on kittiwakes.
