Populations of a host species may exhibit different assemblages of parasites and other symbionts. The loss of certain species of symbionts (lineage sorting, or ‘‘missing-the-boat’’) is a mechanism by which geographical variation in symbiont assemblages can arise. We studied feather mites and lice...
Survey of nasal mites (Rhinonyssidae, Ereynetidae, and Turbinoptidae) associated with birds in Alberta and Manitoba, CanadaDownload
Abstract: Three major lineages of mites (Arachnida: Acari) are parasitic in the nasal passages of birds: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), Cytoditidae, and Turbinoptidae (Astigmata). The most diverse group of avian nasal mites is the Rhinonyssidae, which are obligate...
Altricial young face two significant energetic challenges in the nest: thermoregulation and stress caused by ectoparasites. Ectoparasites feed on blood of nestlings and serve as vectors for bacterial and viral infections. Many bird species line their nests with feathers, which insulate the nest...
