A validation study of phycocyanin sensors for monitoring cyanobacteria in cultures and field samples
(University of Waikato, 2016)Cyanobacteria are photosynthetic prokaryotes present in almost all terrestrial and aquatic environments. Under favourable conditions of high nutrient inputs, high water temperature and adequate light, they can rapidly ... -
Bloom formation, species succession, toxin variability and benthic recruitment of cyanobacteria in Lake Rotorua, Kaikoura
(University of Waikato, 2016)Cyanobacteria are an ancient group of photosynthetic prokaryotes that are found in a wide range of habitats including freshwater lakes and rivers. In aquatic ecosystems, under favourable environmental conditions, cyanobacteria ... -
Capabilities and considerations for the implementation of a phycocyanin sensor to enhance cyanobacteria monitoring in lakes
(University of Waikato, 2017)Bloom-forming cyanobacteria are problematic in recreational waters as humans may be exposed to their toxins via primary contact or ingestion. Cyanobacteria can be monitored using microscopy but this is time consuming, ... -
Elucidating the origin and transmission of tetrodotoxin in New Zealand bivalves
(The University of Waikato, 2021)Tetrodotoxin (TTX) is a potent neurotoxin that acts by selectively targeting sodium channels, blocking propagation of action potentials and causing paralysis. It has been responsible for countless human intoxications and ... -
Elucidating the Origin of Tetrodotoxin in Pleurobranchaea maculata and Stylochoplana sp.
(University of Waikato, 2015)Tetrodotoxin (TTX) is an extremely potent neurotoxin that acts by selectively targeting voltage gated sodium channels blocking propagation of action potentials. Long believed to be present only in pufferfish, TTX has now ... -
Investigating Diet as the Source of Tetrodotoxin in the Grey Side-gilled Sea Slug, Pleurobranchaea maculata
(University of Waikato, 2014)Pleurobranchaea maculata (grey-side gilled sea slug) was discovered to contain the neurotoxin tetrodotoxin (TTX) in 2009 after a spate of dog poisoning cases on the beaches of Auckland, New Zealand. One of the great mysteries ... -
The Role of Viral Systems in Nutrient Cycling
(University of Waikato, 2011)The Te Arawa/Rotorua lakes located in the central North Island of New Zealand have significant cultural, historic, social and economic value. Anthropogenic changes in land use have led to a decline in water quality in some ... -
Spatial and temporal trends of phytoplankton and physiochemical variables in a hypertrophic, monomictic lake
(University of Waikato, 2011)Spatial and temporal variations in the physical, chemical and biological composition of Lake Ōkaro were measured over 16 months. Lake Ōkaro is a small (0.32 km2) hypertrophic, monomictic lake located in the Central Volcanic ...
