| 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 |
| australasian contributions to an understanding of the epidemiology and control of hydatid disease caused by echinococcus granulosus--past, present and future. | for several years after echinococcus granulosus was introduced into australasia from europe, its life cycle was unknown. before the end of the 19th century, however, cystic hydatid disease (chd) was recognized in humans as an important cause of death, although its magnitude was not quantified. during the first 50 years of the 20th century, the urban component declined, but chd remained a serious source of ill-health. during the second half of the 20th century major research contributions have in ... | 1990 | 2210938 |
