| cytogenic studies of hynobiidae (urodela). xiv. analysis of the chromosome of a chinese salamander, batrachuperus pinchonii (david). | the chromosome number of a chinese salamander, batrachuperus pinchonii, was re-examined adults and embryonic specimens had a diploid number of 66, with 33 bivalents during meiosis, in contrast to previous reported results. furthermore, when c-banding analysis was performed with embryos, chromosomes with banding patterns homoeologous to those of salamandrella keyserlingii and hynobius species were found. it appears, therefore, that batrachuperus, salamandrella and hynobius might be derived from a ... | 1998 | 9539957 |
| cytogenetic studies of hynobiidae (urodela) xvi. comparative c-banded karyotype analysis of pseudohynobius flavomaculatus (fei et ye), ranodon shihi (liu) and batrachuperus pinchonii (david). | initial analysis of pseudohynobius flavomaculatus chromosomes determined the chromosome number of this species to be 2n = 52. a re-examination of ranodon shihi chromosomes detected 2n = 66 chromosomes, in contrast with a previous finding of 2n = 64. the c-banding patterns of these two species and that of batrachuperus pinchonii were compared with each other. regions of homoeology in the c-banding pattern among these three species represented 33.51-48.30% of the total length of their chromosomes. ... | 2000 | 10841054 |
| a comparative study of the hyobranchial apparatus in hynobiidae (amphibia: urodela). | the morphology of the adult hyobranchial apparatus has played an important role in understanding the systematics and evolution of urodeles, but the hyobranchial apparatus of hynobiid salamanders has received little attention so far. in this study, the hyobranchial apparatus of eight hynobiid salamanders (hynobius leechii, onychodactylus zhangyapingi, ranodon sibiricus, batrachuperus pinchonii, salamandrella keyserlingii, liua shihi, pachyhynobius shangchengensis and pseudohynobius flavomaculatus ... | 2013 | 23474179 |
