Aboriginal man as an exterminator of Wallaby and Kangaroo populations on Islands Round Australia.

摘要: The occurrence of kangaroos, wallabies and related species (Family Macropodidae) on islands area 90 ha or more round Australia is non-random. Few adjacent to the northwestern, northern eastern coasts have macropods present in contrast a large number near mid-and southwestern most southern coastline. latter group was not visited by aborigines because they lacked watercraft, were apparently too small support human populations. It argued that Aboriginal man, through direct predation, his introduction Dingo, frequent use fire, chiefly responsible for difference representation two groups islands.The median with at least one macropod which are used Aborigines about six times larger than occupied Aborigines. Several possible alternative hypotheses account distribution pattern described above discussed. For these inadequate data hand assess their significance.It suggested provides guide reserve sizes necessary conservation mainland Australia. Areas 5,000 probably needed local long-term persistence macropod, areas 9,000 survival reserves species.
