Didymosphenia geminata is an alga of major concern in temperate regions due to ongoing spread and unprecedented bloom formation. The aim of this study was to identify physical and chemical habitat conditions which affect D. geminata at catchment to patch scales. To examine this, we conducted a field-based survey of 55 distinct waterways across the South(More)
There has been renewed interest in the combined use of high-rate algal ponds (HRAP) for wastewater treatment and biofuel production. Successful wastewater treatment requires year-round efficient nutrient removal while high microalgal biomass yields are required to make biofuel production cost-effective. This paper investigates the year-round performance of(More)
Carbon limitation in domestic wastewater high rate algal ponds (HRAPs) is thought to constrain both microalgal photosynthesis and biomass production. CO2 augmentation is one way of overcoming this carbon limitation; however, high carbon demands due to large microalgal biomass means that the frequency of CO2 supply is likely to be critical to its success.(More)
Acid mine drainage (AMD) is a significant environmental issue worldwide. On the West Coast of the South Island, New Zealand, many AMD-affected streams occur within close proximity to naturally acidic streams, enabling us to compare the response of communities in naturally and anthropogenic acidified systems. We investigated epiphytic diatom communities in(More)
