| revision of the genus parvirostrum fuhrmann, 1908 (cestoda: cyclophyllidea: paruterinidae). | redescriptions are presented of the type-materials of parvirostrum reticulatum fuhrmann, 1908 (type-species of parvirostrum fuhrmann, 1908) from lepidocolaptes albolineatus (passeriformes: dendrocolaptidae) and of p. synallaxis (mahon, 1957) n. comb. (syn. deltokeras synallaxis mahon, 1957) from synallaxis rutilans (passeriformes: furnariidae), both from brazil. p. linusi n. sp. is described from dendrocolaptes platyrostris (dendrocolaptidae) from paraguay. it is characterised by a strobila up t ... | 2001 | 11559843 |
| nucleolar organizer regions in sittasomus griseicapillus and lepidocolaptes angustirostris (aves, dendrocolaptidae): evidence of a chromosome inversion. | cytogenetic studies in birds are still scarce compared to other vertebrates. woodcreepers (dendrocolaptidae) are part of a highly specialized group within the suboscines of the new world. they are forest birds exclusive to the neotropical region and similar to woodpeckers, at a comparable evolutionary stage. this paper describes for the first time the karyotypes of the olivaceous and the narrow-billed woodcreeper using conventional staining with giemsa and silver nitrate staining of the nucleola ... | 2013 | 23569410 |
| mitogenomes of two neotropical bird species and the multiple independent origin of mitochondrial gene orders in passeriformes. | at least four mitogenome arrangements occur in passeriformes and differences among them are derived from an initial tandem duplication involving a segment containing the control region (cr), followed by loss or reduction of some parts of this segment. however, it is still unclear how often duplication events have occurred in this bird order. in this study, the mitogenomes from two species of neotropical passerines (sicalis olivascens and lepidocolaptes angustirostris) with different gene arrange ... | 2018 | 29455315 |
