An investigation of the symbiotic association between the sub-aquatic fungus Dermatocarpon luridum var. luridum and its green algal photobiontFontaine, Kyle Matthew 10 October 2012 (has links)
The biology of the sub-aquatic lichen, Dermatocarpon luridum, was
investigated. This lichen is sparsely distributed within the temperate climatic
zones around the world, colonizing rock along watercourses that regularly
experience water level fluctuations. Specimens collected from Canada and
Austria were cultured using standard growth media. Brightfield microscopy was
used for algal species identification, while fungal ITS, algal ITS and algal actin
gene sequences were used for phylogenetic and population genetic evaluation.
Results were: 1) axenic cultures of the photobiont were successful, while those of
the mycobiont were not successful; 2) Diplosphaera chodatii is the photobiont
associated with D. luridum var. luridum and allies, suggesting algal sharing
between mycobiont species; 3) genetic diversity is high, and gene flow was high
within local populations, but low between continental populations. Diplosphaera
chodatii may be a keystone species contributing to the survival of D. luridum var. luridum along with other sub-aquatic, aquatic and terrestrial lichens.

Aspects of the population genetics and ecology of herbicide resistant annual ryegrass / John M. Matthews.Matthews, John M., 1944- January 1996 (has links)
Bibliography: leaves 180. / viii, 200 leaves : ill. ; 20 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / This study shows the widespread nature of resistance in L. rigidum populations, the tendency to genetic dominance even in early generations of selection and the propensity to display resistance to many herbicides. The fitness of resistant plants and the likely failure of herbicides for weed management suggests that an Integrated Weed Management programme is the best solution. / Thesis (Ph.D.)--University of Adelaide, Dept. of Crop Protection, 1997
