| species of strigea (digenea: strigeidae), parasites of the savanna hawk buteogallus meridionalis (aves: accipitridae) from argentina, with the description of a new species. | a new strigeid digenean, strigea meridionalis sp. n., is described from the small intestine of the savanna hawk, buteogallus meridionalis (latham) (aves: accipitridae), from formosa province, argentina. this species is characterised by the absence of a neck region in the hindbody, the presence of entire testes, a copulatory bursa with a membranous fold originated from the muscular ring (ringnapf) and by the arrangement of vitelline follicles in the forebody. other two strigeid species collected ... | 2009 | 20128239 |
| rickettsial infection in ticks collected from road-killed wild animals in rio de janeiro, brazil. | during 2008-2010, ticks were collected from road-killed wild animals within the serra dos orgãos national park area in the state of rio de janeiro, brazil. in total, 193 tick specimens were collected, including amblyomma dubitatum neumann and amblyomma cajennense (f.) from four hydrochoerus hydrochaeris (l.), amblyomma calcaratum neumann and a. cajennense from four tamandua tetradactyla (l.), amblyomma aureolatum (pallas) and a. cajennense from five cerdocyon thous l., amblyomma longirostre (koc ... | 2012 | 23270184 |
| digenean fauna in raptors from northeastern argentina, with the description of a new species of strigea (digenea: strigeidae). | the digenean fauna of six species of falconiform birds from northeastern argentina is reported and a new species and several new hosts and geographical records are presented. strigea proteolytica n. sp. (strigeidae) is described from buteogallus urubitinga and distinguished from their congeners by the combination of the following characters: plump body, conspicuous proteolytic gland, forebody with scarce vitelline glands, copulatory bursa with a well developed muscular ring (ringnapf), and absen ... | 2014 | 24872182 |
| polyphyly of the hawk genera leucopternis and buteogallus (aves, accipitridae): multiple habitat shifts during the neotropical buteonine diversification. | the family accipitridae (hawks, eagles and old world vultures) represents a large radiation of predatory birds with an almost global distribution, although most species of this family occur in the neotropics. despite great morphological and ecological diversity, the evolutionary relationships in the family have been poorly explored at all taxonomic levels. using sequences from four mitochondrial genes (12s, atp8, atp6, and nd6), we reconstructed the phylogeny of the neotropical forest hawk genus ... | 2006 | 16464261 |
| a review of the feather mite family gabuciniidae gaud amp; atyeo (acariformes: astigmata: pterolichoidea) of brazil, with descriptions of eleven new species. | the feather mite family gabuciniidae currently includes 16 genera and approximately 65 described species associated with birds of nine orders, with the greatest diversity on accipitriformes. in this study, 11 new species are described from the following hosts: aetacarus accipiter sp. nov. from the bicolored hawk accipiter bicolor (vieillot, 1817) (accipitriformes: accipitridae), capitolichus campoflicker sp. nov. from the campo flicker colaptes campestris (vieillot, 1818) (piciformes: picidae), ... | 2020 | 32230117 |
