| no need for disease: testing extinction hypotheses for the thylacine using multi-species metamodels. | population viability analysis (pva) is widely used to assess the extinction risk of threatened species and to evaluate different management strategies. however, conventional pva neglects important biotic interactions and therefore can fail to identify important threatening processes. we designed a new pva approach that includes species interactions explicitly by networking species models within a single 'metamodel'. we demonstrate the utility of pva metamodels by employing them to reinterpret th ... | 2013 | 23347431 |
| phylogeographical population structure of tiger quolls dasyurus maculatus (dasyuridae: marsupialia), an endangered carnivorous marsupial. | tiger quolls, dasyurus maculatus, are the largest carnivorous marsupials still extant on the mainland of australia, and occupy an important ecological niche as top predators and scavengers. two allopatric subspecies are recognized, d.m. gracilis in north queensland, and d.m. maculatus in the southeast of the mainland and tasmania. d.m. gracilis is considered endangered while d.m. maculatus is listed as vulnerable to extinction; both subspecies are still in decline. phylogeographical subdivision ... | 1999 | 10583825 |
| could direct killing by larger dingoes have caused the extinction of the thylacine from mainland australia? | invasive predators can impose strong selection pressure on species that evolved in their absence and drive species to extinction. interactions between coexisting predators may be particularly strong, as larger predators frequently kill smaller predators and suppress their abundances. until 3500 years ago the marsupial thylacine was australia's largest predator. it became extinct from the mainland soon after the arrival of a morphologically convergent placental predator, the dingo, but persisted ... | 2012 | 22567093 |
