Antarctic ecosystems in transition - life between stresses and opportunities
(Wiley, 2020)Important findings from the second decade of the 21st century on the impact of environmental change on biological processes in the Antarctic were synthesised by 26 international experts. Ten key messages emerged that have ... -
Characterisation of Antarctic cyanobacteria and comparison with New Zealand strains
(Springer, 2013)Cyanobacterial mats are common in Antarctic lakes, ponds and on moist soils. The species comprising these mats have adapted to tolerate extreme conditions (e.g. high salinities and UV radiation, freezing and extended periods ... -
Distribution of tetrodotoxin in the New Zealand clam, Paphies australis, established using immunohistochemistry and liquid chromatography-tandem quadrupole mass spectrometry
(MDPI, 2018)Tetrodotoxin (TTX) is one of the most potent neurotoxins known. It was originally thought to only occur in puffer fish but has now been identified in twelve different classes of freshwater and marine organisms, including ... -
Effect of river flow, temperature, and water chemistry on proliferations of the benthic anatoxin-producing cyanobacterium Phormidium
(2016-12-15)Proliferations of the benthic anatoxin-producing cyanobacterium Phormidium are increasing in prevalence in cobble-bed rivers worldwide. This proliferation is of particular concern when rivers are used as sources of drinking ... -
Effects of fine sediment on seagrass meadows: A case study of Zostera muelleri in pāuatahanui inlet, New Zealand
(MDPI, 2020)Seagrass meadows are vulnerable to fine sediment (mud) pollution, with impacts usually attributed to reduction in submerged light. Here we tested two non-exclusive hypotheses, that mud particles (≤63 μm) impact seagrasses ...

Nutrient and sediment dynamics in two coastal plain rivers in the Bay of Plenty
(The University of Waikato, 2022)A large amount of literature concerns eutrophication development in lakes, reservoirs, or estuaries. In contrast, literature concerning to the development of eutrophication in flowing waters is more scarce and, in New ... -
Relationships between cyanobacteria and water colour in Central North Island lakes of contrasting trophic status
(The University of Waikato, 2022)Nutrient enrichment of lakes and rising global temperatures promote the proliferation of cyanobacteria. Cyanobacterial blooms are becoming more widespread and increasing in frequency, size and duration, causing a cascade ... -
Remote sensing of dynamics and aboveground biomass of seagrass in Tauranga Harbor (Bay of Plenty), New Zealand
(The University of Waikato, 2021)Seagrasses are angiosperm plants that are completely adapted to life in seawater. They are distributed widely across the climatic regions, ranging from the tropics to temperate regions, in both inter-tidal and sub-tidal ... -
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 ... -
Sediment-effects on seagrass Zostera muelleri in New Zealand
(The University of Waikato, 2021)Seagrasses are ecosystem engineers that provide important ecological functions and societal economic values. Examples of the services that seagrasses provide are: sediment and coastal stability; maintenance of water quality; ...
