Assessing vulnerability of New Zealand lakes to loss of conservation value from invasive fish impacts
(John Wiley & Sons Ltd, 2016)1. Predictions of invasion risk for seven non-indigenous fish species, ecological impact scores for individual species, and lake conservation rankings were linked to develop Invasion Risk Impact (IRI) and Lake Vulnerability ... -
Average score per metric: an alternative metric aggregation method for assessing wadeable stream health
(R S N Z Publishing, 2008)Integrating multiple metrics derived from stream macroinvertebrate communities into single scores that reflect ecological condition can bridge the needs of multiple groups using biomonitoring data. Macroinvertebrate metrics ... -
Connectivity and complexity of floodplain habitats govern zooplankton dynamics in a large temperate river system
(Wiley, 2013)1. Large river–floodplain systems are characterised by seasonal flow variability. High flows lead to hydrological connection between the main channel and inundated off-channel lakes, wetlands and floodplains, which provide ... -
Conservation status of New Zealand freshwater invertebrates, 2013
(Department of Conservation, 2014)The conservation status of 644 freshwater invertebrate taxa, across five Phyla, 28 Orders and 75 Families, was assessed using the New Zealand Threat Classification System (NZTCS) criteria. Forty-six species were ranked ... -
Contrasting responses to catchment modification among a range of functional and structural indicators of river ecosystem health
(2009)1. The value of measuring ecosystem functions in regular monitoring programs is increasingly being recognised as a potent tool for assessing river health. We measured the response of ecosystem metabolism, organic matter ...

Partitioning along reproductive niche dimensions in sympatric New Zealand freshwater bivalve species
(The University of Waikato, 2021)Sympatric species of freshwater mussels in the order Unionida may need to partition resources to enable coexistence due to their relatively sedentary life-style and complex symbiotic life-phase dependent on host-fish. ... -
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 ... -
eDNA-based detection of New Zealand freshwater mussel (kākahi) populations using digital PCR
(The University of Waikato, 2020)Globally, freshwater mussels are one of the most endangered taxa due to pollution, nutrient loading, habitat fragmentation, and species introduction attributable to anthropogenic activities. New Zealand freshwater mussels ... -
Quantifying relationships between kōura (Paranephrops planifrons) abundance and micro-habitat features in Waikato hill-country streams
(The University of Waikato, 2019)Kōura (Paranephrops planifrons) is considered a taonga species by Māori and was once an abundant traditional fishery harvested throughout New Zealand. Kōura populations are under pressure in Waikato hill-country streams ... -
Field and laboratory investigations of Echyridella menziesii (Unionida: Hyriidae) interactions with host fishes
(The University of Waikato, 2019)Globally, the study of freshwater mussels has increased markedly in recent years, spurred on by recognition that many mussel populations are declining or are already extinct. The New Zealand freshwater mussel Echyridella ...
