Sarcophilus Harrisii

Today, the Tasmanian devil ( Sarcophilus harrisii ) is found only on the island of Tasmania, despite once being widespread across mainland Australia. While the devil is thought to have become extinct on the mainland approximately 3000 years ago, three specimens were collected in Victoria (south-eastern Australia) between 1912 and 1991, raising the possibility that a relict mainland population survived in the area. Alternatively, these devils may have escaped captivity or were deliberately released after being transported from Tasmania, a practice that has been strictly controlled since the onset of devil facial tumour disease in the early 1990s. Such quarantine regimes are important to protect disease-free, ‘insurance populations’ in zoos on the mainland. To test whether the three Victorian devils were members of a relict mainland population or had been recently transported from Tasmania we identified seven single nucleotide polymorphisms (SNPs) in the mitochondrial genome that can distinguish between Tasmanian and ancient mainland populations. The three Victorian devil specimens have the same seven SNPs diagnostic of modern Tasmanian devils, confirming that they were most likely transported from Tasmania and do not represent a remnant population of mainland devils.

Sarcophilus Harrisii

The Tasmanian devil, S. harrisii, is polyovular and monoestrus and embryonic diapause was not found. The mean number of pouch young for 69 litters was found to be 2.95. The number of young in a litter varies with the age of the mother. More young are born than can be accommodated in the pouch. The time of breeding varies from year to year, mating taking place in March. The percentage of breeding females varies annually as well as from place to place, being found to be as low as 31 % in one area. The devil has a high reproductive potential because there are no losses at the pouch-young stage. This is offset by poor recruitment of juveniles into the population. Pseudopregnancy was found to occur. The sex ratio of both pouch young and adults favoured the female. The development and growth of the young is described.

Sarcophilus Harrisii

Tooth microwear patterns in the predator Thylacinus cynocephalus and the scavenger Sarcophilus harrisii were examined as potentical indicators of dietary differences and occlusal mechanics. Homologous proximal facets on the metacrista of the maxillary right 3rd molar of each species were examined as gold coated replicas under the SEM. The density, dimensions and relative abundances of microwear features were recorded. Significant intrafacet microwear variation exists relative to the direction of the occlusal stroke in Thylacinus. Striation and pit frequency are inversely correlated down the facet, with striations being more frequent at the leading edge; pits are larger and more frequent at the trailing edge. This pattern supports proposed models of the carnassial chewing stroke, where it is predicted that the shearing component, that produces striations, is greater at the leading edge of the facet, while the compression component of the occlusal stroke, which results in relatively more pits, is greater at the trailing edge of the facet. Significant intraspecific and interspecific variation is found in microwear feature dimensions, and densities. Pit diameters and densities are significantly greater in Thylacinus, although only approximately 11% of the total variance in these features was attributable to species differences. The remaining variance was distributed equally between individuals of the same species, and the leading and trailing regions of the facet. The high degree of intraspecific variability indicates that in carnivorous species at least, a sufficient number of individuals must be examined before accurate dietary interpretations and comparisons with other species can be made.
