| two new and two redescribed species of anonchotaenia (cestoda: paruterinidae) from south american birds. | morphological examination of novel specimens of paruterinid cestodes from passerine birds from brazil and chile and of museum specimens from paraguay revealed two new species: anonchotaenia prolixa sp. n. from elaenia albiceps chilensis hellmayr from chile, and anonchotaenia vaslata sp. n. from tyrannus melancholicus (vieillot) (type host) and myiodynastes maculatus (statius muller) from paraguay. the generic diagnosis of anonchotaenia conn, 1900 is amended, prompted by the presence of the armed ... | 2014 | 25549500 |
| the ruby-crowned tanager tachyphonus coronatus vieillot, 1822 (passeriformes: thraupidae) as a new host for isospora ramphoceli berto, flausino, luz, ferreira, lopes, 2010 in brazil. | despite 12 coccidian species had been recorded from passerines of the thraupidae family, none of them has been reported in the parque nacional do itatiaia, in southeastern brazil. this locality is a protected area with a high degree of vulnerability, and is considered a "conservation island" of biodiversity. the aim of the current work was describe isospora ramphoceli berto, flausino, luz, ferreira, lopes, 2010 from ruby-crowned tanagers tachyphonus coronatus vieillot, 1822 in the parque naciona ... | 2017 | 28426404 |
| molecular diversity and coalescent species delimitation of avian haemosporidian parasites in an endemic bird species of south america. | haemoproteus spp. and plasmodium spp. are blood parasites that occur in birds worldwide. identifying the species within this group is complex, especially in wild birds that present low parasitemia when captured, making morphological identification very difficult. thus, the use of alternative tools to identify species may be useful in the elucidation of the distribution of parasites that circulate in bird populations. the objectives of this study were to determine the prevalence and parasitemia o ... | 2020 | 33030600 |
