It explores the hypothesis that the composition of wetland vegetation is determined by components of the water regime, namely depth, duration and the rate and timing of flood and drawdown. / Thesis (Ph.D.)--University of Adelaide, Cooperative Research Centre for Freshwater Ecology and School of Earth and Environmental Sciences, Discipline of Environmental Biology, 2004
