| reconstructing an island radiation using ancient and recent dna: the extinct and living day geckos (phelsuma) of the mascarene islands. | mitochondrial (12srrna and cyt b, 1086 bp) and nuclear (c-mos, 374 bp) dna sequences were used to investigate relationships and biogeography of 24 living and extinct taxa of phelsuma geckos. monophyly of phelsuma and sister relationship to the sw african rhoptropella is corroborated. phelsuma originated on madagascar and made multiple long-distance invasions of oceanic islands including the mascarenes, aldabra, comores, seychelles, andamans, and perhaps pemba. the mascarenes were probably coloni ... | 2004 | 15019612 |
| high risks of losing genetic diversity in an endemic mauritian gecko: implications for conservation. | genetic structure can be a consequence of recent population fragmentation and isolation, or a remnant of historical localised adaptation. this poses a challenge for conservationists since misinterpreting patterns of genetic structure may lead to inappropriate management. of 17 species of reptile originally found in mauritius, only five survive on the main island. one of these, phelsuma guimbeaui (lowland forest day gecko), is now restricted to 30 small isolated subpopulations following severe fo ... | 2014 | 24963708 |
