| zw sex chromosomes in australian dragon lizards (agamidae) originated from a combination of duplication and translocation in the nucleolar organising region. | sex chromosomes in some reptiles share synteny with distantly related amniotes in regions orthologous to squamate chromosome 2. the latter finding suggests that chromosome 2 was formerly part of a larger ancestral (amniote) super-sex chromosome and raises questions about how sex chromosomes are formed and modified in reptiles. australian dragon lizards (agamidae) are emerging as an excellent model for studying these processes. in particular, they exhibit both genotypic (gsd) and temperature-depe ... | 2019 | 31671601 |
| a simple non-invasive protocol to establish primary cell lines from tail and toe explants for cytogenetic studies in australian dragon lizards (squamata: agamidae). | primary cell lines were established from cultures of tail and toe clips of five species of australian dragon lizards: tympanocryptis pinguicolla, tympanocryptis sp., ctenophorus fordi, amphibolurus norrisi and pogona vitticeps. the start of exponential cell growth ranged from 1 to 5 weeks. cultures from all specimens had fibroblastic morphology. cell lines were propagated continuously up to ten passages, cryopreserved and recovered successfully. we found no reduction in cell viability after shor ... | 2008 | 19199067 |
| life history influences how fire affects genetic diversity in two lizard species. | 'fire mosaics' are often maintained in landscapes to promote successional diversity in vegetation with little understanding of how this will affect ecological processes in animal populations such as dispersal, social organization and re-establishment. to investigate these processes, we conducted a replicated, spatiotemporal landscape genetics study of two australian woodland lizard species [amphibolurus norrisi (agamidae) and ctenotus atlas (scincidae)]. agamids have a more complex social and te ... | 2014 | 24750427 |
