| intra-generic and interspecific karyotype patterns of leptodactylus and adenomera (anura, leptodactylidae) with inclusion of five species from central amazonia. | the genera leptodactylus and adenomera comprise 92 species distributed throughout the neotropical region. these species have a modal diploid chromosome number 2n = 22. however, chromosome rearrangements are evident in the differentiation of five intra-generic groups in the genus leptodactylus (l. fuscus, l. latrans, l. marmoratus (formally composed by the species of the genus adenomera), l. melanonotus, l. pentadactylus), yet it is not clear if there is a karyotype pattern for each group. aiming ... | 2016 | 26650375 |
| chondrocranial morphology of leptodactylus larvae (leptodactylidae: leptodactylinae): its utility in phylogenetic reconstruction. | chondrocranial morphology of leptodactylid frogs is scarcely known and has not been completely described for any species of leptodactylus. we describe the diversity of chondrocranial morphology in the genus leptodactylus based on the analysis of 22 species, representing the four species groups: the fuscus group, ocellatus group, melanonotus group, and pentadactylus group. furthermore, 26 characters are identified and used in a phylogenetic analysis. the phylogenetic analysis using physalaemus, c ... | 1998 | 29852719 |
