brueelia (phthiraptera: ischnocera: philopteridae) of north american nine-primaried oscines (aves: passeriformes: passerida) with descriptions of nine new species.nine new species of chewing lice in the genus brueelia kéler, 1936 , are described from north american hosts. they are brueelia thorini n. sp. from haemorhous mexicanus frontalis (say, 1822) and haemorhous mexicanus potosinus griscom, 1928; brueelia straseviciusi n. sp. from haemorhous purpureus (gmelin, 1789); brueelia mattsonae n. sp. from coccothraustes vespertinus brooksi (grinnell, 1917); brueelia novemstriata n. sp. from icterus wagleri wagleri sclater, 1857, and i. parisorum bonaparte, 18 ...201931730417
extensive gene flow characterizes the phylogeography of a north american migrant bird: black-headed grosbeak (pheucticus melanocephalus).we describe range-wide phylogeographic variation in the black-headed grosbeak (pheucticus melanocephalus), a songbird that is widely distributed across north american scrublands and forests. phylogenetic analysis of mitochondrial dna (mtdna, n=424) revealed three geographically structured clades. one widespread clade occurs throughout the rocky mountains, great basin, and mexican plateau, a second clade is found on the pacific coast and in coastal ranges; and, a third in the sierra madre del sur ...201424841539
a hybrid zone revisited: molecular and morphological analysis of the maintenance, movement, and evolution of a great plains avian (cardinalidae: pheucticus) hybrid grosbeaks (pheucticus melanocephalus) and rose-breasted grosbeaks (pheucticus ludovicianus) are passerine bird species known to hybridize in the great plains of north america. both extrinsic (environmental) and intrinsic factors (pre- and postzygotic reproductive isolation) have been credited for the generation and maintenance of the grosbeak hybrid zone, but little is known about the genetic characteristics of this hybrid zone. to investigate the stability and extent of the grosbea ...200919619198
nasal mites of the subfamily speleognathinae (ereynetidae) from birds in texas.nasal mites of the subfamily speleognathinae were recovered from several species of birds in texas. new host records include ophthalmophagus striatus (crossley) 1952 from columbigallina passerina, boydaia clarki fain 1963 from callipepla squamata, boydaia falconis fain 1956 from falco sparverius, and boydaia tyrannus ford 1959 from myiarchus cinerascens. also recovered was astrida coccyzae pence 1972 from coccyzus americanus. boydaia pheucticola sp. n. from pheucticus melanocephalus is described ...1976932921
a systematic review of the subfamily syringophilinae (acari: syringophilidae) of the nearctic region. part 1: quill mites associated with passerines (aves: passeriformes).quill mites belonging to the subfamily syringophilinae lavoipierre, 1953 associated with the nearctic passeriform birds are revised. all of the 49 known species, which are grouped in seven genera, are recorded. among them, four new species are described: syringophiloidus audubioni sp. nov. from spizella breweri (cassini) (emberizidae), syringophilopsis catesbyi sp. nov. from vireo olivaceus (linnaeus) (vireonidae), s. wilsoni sp. nov. from pheucticus melanocephalus (swainson) (cardinalidae), and ...201627394276
