This paper discusses the interactions between the large and medium-sized marsupials, the introduced ruminant domestic stock, and the environment in the arid zone of Australia. The grazing of sheep and cattle has produced suitable subclimax pastures which today favor two sympatric kangaroos but not the smaller bandicoots and wallabies. Tall grass tussocks used as shelter by the latter have been grazed down by the ruminants, and replaced by "marsupial lawns" or xeric spinifex, depending on… 

Impact of Red Kangaroos on the Pasture Layer in the Western Australian Arid Zone.

Unless more effective methods of kangaroo control are integrated with stock reductions, the recovery of degraded rangeland pastures is likely to be severely limited.

Managed livestock grazing is compatible with the maintenance of plant diversity in semidesert grasslands.

It is suggested that livestock grazing of semidesert grasslands with a short evolutionary history of ungulate grazing has altered plant composition, but has not caused declines in the dominant perennial grasses or in species richness as predicted by the preceding literature.

The Diversity and Abundance of Lizards in Arid Australia: A New Hypothesis

It is suggested that lizards are better suited than other vertebrates to infertile and arid environments because of their morphological and physiological characteristics; this phenomenon reaches its climax in Australia.

Marsupial grazing lawns in Tasmania : maintenance, biota and the effects of climate change

Native vertebrate grazers have been shown to be a critical element in the structuring of natural grasslands and lawns. Tasmania has a high density of native grazers and lawns have formed sporadically

Causes of extinction of vertebrates during the Holocene of mainland Australia: arrival of the dingo, or human impact?

The arrival of the dingo in mainland Australia is believed to have caused the extinction of three native vertebrates: the thylacine, the Tasmanian devil and the Tasmanian native hen. The dingo is

The Perils of Being Populous: Control and Conservation of Abundant Kangaroo Species

It is envisage that a marriage of localised consumptive and non-consumptive uses in the indigenous-protected-area estate can better sustain abundant kangaroo populations into the future.

Population Dynamics of Eastern Grey Kangaroos in Temperate Grasslands

This thesis is about the dynamics of eastern grey kangaroo (Macropus giganteus) populations and their food supplies in temperate grasslands of south-eastern Australia. It is based on the study of

Grazing Lawns: Animals in Herds, Plant Form, and Coevolution

Natural selection at the individual level, acting on both animals and plants to produce coevolution among members of the same trophic web, can regulate such ecosystem processes as energy flow and nutrient cycling, and contribute to species coexistence and the resultant species diversity of communities.

Aridity, faunal adaptations and Australian Late Pleistocene extinctions

Abstract The faunal extinctions of the Late Pleistocene saw the disappearance of a suite of giant marsupials, birds and reptiles from the Australian landscape. Attempts to explain these extinctions

The three species of herbivore, during the study period of 1 yr and under the conditions described, were found to have food preferences that were specific enough to justify the conclusion that the plants of the habitat and the threespecies of animals constitute an ecosystem.

The pattern of density changes between fixed quadrats over a period of time was consistent with the idea that within the kangaroo population there was a spectrum of mobility types, which resulted in some of the population accumulating in relatively more favourable parts.

Reproductive behaviour in the Red Kangaroo, Megaleia rufa, in captivity

Breeding in the red kangaroo in captivity was virtually continuous but there was evidence that some females showed a slightly reduced fecundity in the winter months and the foster young were reared normally.

A relationship has been demonstrated between the levels of some constituents of the blood of euros and thelevels of protein in the vegetation which they graze and a theory of population control based on nutrition is suggested.
