Abstract:

Blue-flowered Conospermum are endemic to Western Australia, and show great potential as cut flowers. Propagation from cuttings or seed proved difficult, and root initiation in vitro is problematic. This thesis examines the floral biology of the species and the possibility of using somatic embryogenesis to overcome propagation problems. A survey of explant tissue types for C. eatoniae and C. caeruleum was carried out to identify tissue that could be induced into embryogenic pathways. Vegetative, semi-floral and floral buds were initiated into culture from February to June, but were found

Abstract:

Echinococcus granulosus is a small endoparasitic tapeworm which is recognised as one of the world's major zoonoses affecting humans and domestic animal. The adult worm inhabits the intestinal tract of a variety of canids, while the larval or metacestode stage develops in the organs of sheep, cattle, pigs, other ungulates, or humans and causes hydatid disease. Hydatid disease constitutes a serious public health problem with considerable morbidity and mortality. At present, effective treatment and control programs for this disease have not been achieved. Major deficiencies still exist in

Abstract:

The aerial shoot pigments of three epiphytic mistletoes and their hosts were examined and the results were found to concur with earlier reports. Emphasis was placed on the mistletoe Phoradendron juniperinum. Absorbance spectroscopy indicated a very similar ratio of pigments in both the aerial tissue of the mistletoe and its juniper host. Spectroscopic examination found the presence of chlorophyll in the endophytic tissue of the genus Phoradendron for the first time. Total chlorophyll concentrations of the endophytic tissue of Phoradendronjuniperinum were found to be approximately 10% that of a

Abstract:

The objective of my thesis was to develop novel techniques and methods to probe the dielectric properties of biomembranes in air and their natural environment - liquid solution. The dielectric constant ε(r) of biomembranes is a parameter especially important in cell electrophysiology as it ultimately determines the ion membrane permeability, the membrane potential formation or the action potential propagation velocity, among others. However, no technique is able to provide this quantity with the required nanoscale spatial resolution and in electrolyte solution. AFM is an extremely versatile

Abstract:

Ephedra (Gnetales) is a gymnosperm genus with a long evolutionary history; the first dispersed pollen grains with affinity to the group are known already from the Permian. This thesis focuses on the evolutionary history of the group and different aspects of its pollination mechanisms. Despite the limited number of extant species of the genus (50-60), and a low morphological and genetic divergence among species, there is variation in pollination syndrome in the genus. The prevailing state in Ephedra, and most gymnosperms, is wind pollination. It is therefore surprising that one species, E. foem

Abstract:

Corals combine photosynthesis and calcification in an intricate and delicately balanced relationship to form large biomineralized structures that are dominant features of tropical coastlines worldwide. Coral reefs have great scientific and economic importance but have recently experienced widespread decline attributed to increasing anthropogenic pressure on reef systems. Physical damage events, such as ship groundings, when coupled with existing nutrient stress and changing global climate present a poor outlook for successful natural recovery of reef communities. The main goal of the proposed
