Measurements and modelling of eutrophication processes in Lake Rotoiti, New Zealand
… three stations in morphologically complex Lake Rotoiti, North Island, New Zealand, with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations. There was no overarching statistical relationship between measured environmental …

Sediment-Pore Water Chemistry of Taupo Volcanic Zone Lakes and the Effect Trophic State has on Exchange with the Water Column
… monomictic TVZ lakes (Taupo, Tarawera, Okataina, Rotoiti and Ngapouri) of widely varying trophic state, in order to evaluate the interaction between sediments and lake water. In particular, 15N enrichment in the benthic nepheloid layer (BNL), sediment-pore water geochemistry, the lead record in …

Kōura (Paranephrops planifrons) populations in the Te Arawa lakes: An ecological assessment using the traditional Māori tau kōura harvesting method and recommendations for sustainable management
… customary fisheries in some CNI lakes (Rotomā, Rotoiti, Tarawera, and Taupō) where large populations of kōura still exist. Nevertheless, there is considerable anecdotal evidence of declines in populations of kōura in the Te Arawa lakes district since European settlement. A number of …

Effects of lake trophic state and seasonal cycling on production and bioaccumulation of methylmercury in Te Arawa Lakes
… in trout, koura, and kakahi from Lakes Rotorua, Rotoiti, and Rotomahana exceeded WHO recommended safety thresholds. This study also found that a substantial proportion of THg was comprised of MeHg, which was predominantly accumulated in muscle tissue, whereas THg was primarily concentrated in the …

The distribution and dynamics of planktonic rotifera in the North Island, New Zealand
… trophic state and mixing regime: Lakes Tikitapu, Rotoiti, Okaro and Ngaroto. Total rotifer abundances were consistently lowest in winter. The temporal occurrence of species assemblages within lakes related to mixing pattern, with different communities in stratified (or relatively stable) and …
