Abstract:
This thesis is involved with changes that have occurred to small mammal populations following a major disturbance in the Anglesea region as a result of the 1983 Ash Wednesday fires. Fire, with its effects on spatial and temporal heterogeneity, was found to be an important factor in the maintenance of vegetation and small mammal community structure and diversity in the region. Successional changes in vegetation and small mammal communities were described by multivariate analyses, using data collected annually from 22 study sites. The use of factor analysis techniques, in reducing the annual cap

Abstract:
Marsupial moles (genus Notoryctes) are the most highly specialised burrowing marsupials. The specialisations of the appendicular musculo-skeletal system of the marsupial moles are extensive and widespread; the major alterations are concentrated in, but not restricted to, the forelimb. Many of the derived features of the muscular system appear to be adaptations for improving the mechanical advantage of the limbs for burrowing. A number of the specialisations of the muscular system of the marsupial moles are convergent with those previously documented in other fossorial mammals, including golden

Abstract:
Genomic imprinting is responsible for monoallelic gene expression that depends on the sex of the parent from which the alleles (one active, one silent) were inherited. X-chromosome inactivation is also a form of monoallelic gene expression. One of the two X chromosomes is transcriptionally silenced in the somatic cells of females, effectively equalising gene dosage with males who have only one X chromosome that is not complemented by a gene poor Y chromosome. X chromosome inactivation is random in eutherian mammals, but imprinted in marsupials, and in the extraembryonic membranes of some place
