A Diet Study Of Australia's Most Critically Endangered Mammal, Gilbert's Potoroo, Potorous Gilbertii (Marsupialia : Potoroidae), Vinh Nguyen
Theses : Honours
After 125 years of presumed extinction, Gilbert's Potoroo (Potorous gilbertii) was rediscovered in 1994 in Two Peoples Bay Nature Reserve, Albany. As only one population is known to exist, conservation is of prime importance. Faecal analysis was used to examine the diet of P. gilbertii. The species was found to be predominantly mycophagous (fungus-feeding) with invertebrate and plant matter fanning only a small part of its diet. Fungal material made up more than 90% of faecal matter throughout the year. A total of 44 fungal spore types were discerned. Of these, five were tentatively identified to species level with the …
Management Of A Bioeroding Sponge On The Pearl Oyster, Pinctada Maxima, Luisa Rawlinson
Management Of A Bioeroding Sponge On The Pearl Oyster, Pinctada Maxima, Luisa Rawlinson
Theses : Honours
This thesis examines environmentally and economically viable ways to manage a sponge that is bioeroding the pearl oyster, Pinctada maxima, in pearl oyster farms throughout north-western Australia. The sponge is causing a massive loss in revenue to the pearling industry as a result of damage to the half-shell, the pearl and, often, death of the oyster. The information arising from this study is important for pearl producers and the Australian pearling industry, to ensure that the best quality P. maxima can be grown in a way that will not have adverse effects on the pristine environment in which these …
An Examination Of The Impact Of Moon Phase On Catch Rates Of The Western Rock Lobster, Petra Roberts
An Examination Of The Impact Of Moon Phase On Catch Rates Of The Western Rock Lobster, Petra Roberts
Theses : Honours
The western rock lobster is the most valuable single-species fishery in Australia returning a commercial value of around $250 million annually. This fishery is considered fully exploited and requires careful management to ensure a viable and sustainable fishery. Scientists at Marine Research Laboratory, Western Australia have already built detailed computer models of the lobster fishery and further research is required to continuously update and refine these models to provide an accurate picture of the fishery. One area of interest that could improve this model is the impact of the moon phase, if any, on the daily catch rates of the …
Salinity Tolerance Of Selected Ectomycorrhizal Fungi (Pisolithus Tinctorius Pers.) And Ectomycorrhizal Eucalypts, Ben Bradshaw
Salinity Tolerance Of Selected Ectomycorrhizal Fungi (Pisolithus Tinctorius Pers.) And Ectomycorrhizal Eucalypts, Ben Bradshaw
Theses : Honours
Increasing soil salinity has become a major problem worldwide. It has led to a reduction in the amount of arable land, has put at risk the supply of freshwater and threatens the existence of many natural habitats. The major increase in salinity has been attributed to human activities such as clearing of natural vegetation and large-scale irrigation programmes. The alleviation of this problem has focussed on changed management strategies. the most significant of which is the re-establishment of deep rooted plants in sail affected areas. This, however, is difficult because of the variation in salt tolerance of such plants and …
