| the last scream: the distress call of a probably extinct brazilian anuran (holoaden bradei lutz, 1958). | the genus holoaden miranda-ribeiro (anura, craugastoridae, holoadeninae) includes four species endemic to the southeastern brazilian atlantic forest, which occur in cloud forests at high elevations (lutz 1958, pombal et al. 2008, martins & zaher 2013). out of these, two species are considered threatened by ministério do meio ambiente (2014): h. bradei is classified as critically endangered (cr) and h. luederwaldti as endangered (en). holoaden bradei might be already extinct in the wild, as it ha ... | 2016 | 27811647 |
| the karyotype of holoaden luederwaldti (anura, strabomantidae), with report of natural triploidy. | the genus holoaden includes three species described so far, but the only published cytogenetic data is from holoaden bradei, with the karyotype 2n = 18, based on conventional staining. in the present paper we report, for the first time, data on chromosomes of h. luederwaldti, which presented 2n = 18 and a case of natural triploidy, with 2n = 3x = 27. in this sample, another karyotypic variation was observed due to the occurrence of two types of chromosome 8, which present submetacentric or subte ... | 2012 | 22980505 |
