| new zealand forest-dwelling skinks of the oligosoma oliveri (mccann) species-complex (reptilia: scincidae): reinstatement of o. pachysomaticum (robb) and an assessment of historical distribution ranges. | the forest-dwelling skinks of the oligosoma oliveri ('marbled skink') species-complex, from the north island of new zealand, have proven difficult taxonomically because all mainland populations are extinct, obscuring patterns of distribution and population interaction. twenty-four small insular populations have survived off the north-east coast of the north island, which are at present classified into three species. in this paper i re-assess the available phenotypic, ecological, biogeographic an ... | 2019 | 31719439 |
