Assessing New Zealand's spider (Araneae) fauna, using DNA barcoding
(The University of Waikato, 2018)The ability to accurately monitor biological diversity is the foundation to most ecological research. However, the morphological identification of spiders, as with many arthropod taxa, is often complicated by phenotypic ... -
Comparison of riparian willows and riprap as habitat for fish and invertebrates in the Waikato River
(University of Waikato, 2011)Willows (Salix spp.) are an abundant alien tree and have been the mainstay of river bank protection throughout New Zealand. Riprap is another method of bank stabilisation consisting of rocks used to amour shorelines to ... -
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 ... -
Effects of emergent structure on the abundance and size distribution of Trichoptera in Bay of Plenty hill country streams
(The University of Waikato, 2018)Restoration of streams is not limited to recreating structural habitat complexity, but also requires recolonisation of biota that had been excluded prior to restoration. Aquatic insects are a key component of a streams ... -
Effects of native forest and pastoral land use on the population dynamics and trophic role of the New Zealand freshwater crayfish Paranephrops planifrons (Parastacidae)
(The University of Waikato, 2000)Deforestation and conversion to pasture of over 50% of land area has affected the water quality, physical habitat, and fish and benthic invertebrate communities of New Zealand streams, but the impact of land use change on ... -
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 ... -
Food webs in the lower Waikato River and the role of hydrogeomorphic complexity
(University of Waikato, 2014)Large rivers are fundamental to human societies and consequently their ecosystems have come under increasing pressure from a range of developments and uses. Despite this, there is still a major knowledge gap understanding ... -
The influence of connectivity on the functional role of a natural and re-constructed side-arm in the lower Waikato River
(University of Waikato, 2011)This thesis was a comparative study of a natural and a recently re-constructed (artificial) side-arm in the lower Waikato River. A twelve monthly temporal investigation into (i) the physico-chemical variables, nutrient and ... -
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 ... -
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. ... -
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 ... -
Remediating small-scale migratory fish barriers with floating fish ramps
(The University of Waikato, 2018)Instream barriers are a well-documented stressor for diadromous fish species, and can be numerous and costly to remediate. In New Zealand, previous experiments have investigated the swimming ability of indigenous migratory ... -
Sources and effects of catchment-derived bioavailable contaminants in Hamilton urban streams
(University of Waikato, 2013)Awareness of the consistently degraded state of urban streams, with lower biodiversity has heightened worldwide, increasing restoration initiatives to ameliorate the adverse effects. The present study examined anthropoge ... -
The ecology of constructed ponds on the lower Waikato River floodplain: implications for waterfowl management
(University of Waikato, 2014)Numerous ponds have been constructed in recent years on the lower Waikato River floodplain yet many waterfowl populations are in decline. Overseas research highlights the importance of constructed ponds for waterfowl ... -
The link between floodplain inundation and whitebait food supplies in the lower Waikato River
(University of Waikato, 2015)Globally, many large, lowland rivers are regulated due to the construction of stopbanks and flood protection schemes. Many of these changes now govern discharge regimes and lateral floodplain interactions. These modifications, ...
