Long-term zooplankton dynamics in Lake Taupō: 2000-2020
(The University of Waikato, 2021)Long-term monitoring is essential for distinguishing between natural and anthropogenically induced changes within ecosystems, particularly those with high degrees of natural fluctuation. In order to gain further understanding ... -
Interactions between freshwater mussels and non-native species
(The University of Waikato, 2020)Biological invasions contribute to ecosystem change globally, with a disproportionate and intensified impact in freshwaters. This process is exacerbated in modified systems such as hydrogeneration reservoirs that promote ... -
Zooplankton communities in small Waikato lakes and ponds: are natural waters and farm dams the same?
(The University of Waikato, 2019)Ponds have been identified as biodiversity ‘hotspots’ that play an important role in supporting and maintaining biodiversity. In freshwater ecosystems, zooplankton are an essential trophic link between algae and fish, and ... -
Community composition and distribution of macroinvertebrates on natural and artificial substrates in North Island lakes and ponds
(The University of Waikato, 2019)Artificial structures in freshwater ecosystems are becoming increasingly common. The introduction of these structures in marine systems lead to changes in the physical structure and the biotic assemblages. Even though ... -
Evaluating the implications of recent filter-feeding Daphnia invasions for kākahi (Echyridella menziesii)
(The University of Waikato, 2019)Freshwater mussels function as key ecosystem engineers due to their highly efficient filter feeding and bioturbating abilities, which enhance water clarity and promote nutrient cycling. Although they play a crucial role ...
