The role of the deposit feeding bivalve Macomona liliana in a simple biophysical model for predicting estuarine ecosystem tipping points
(The University of Waikato, 2022)Estuaries are highly productive, coastal marine environments that provide vital ecosystem functions supporting human health. Throughout history, many major settlements have been established adjacent to estuaries, so to ... -
Spatial structuring and patterns of connectivity among Antarctic toothfish (Dissostichus mawsoni) stocks in the Southern Ocean: a view through otolith chemistry
(The University of Waikato, 2022)An important prerequisite of sustainable fisheries management is knowledge about the spatial structure of fish populations. Such information provides a basis for understanding population dynamics and connectivity as well ... -
Implications of sea-level rise on estuarine benthic biodiversity and ecosystem functioning
(The University of Waikato, 2022)Estuarine habitats are among the most productive ecosystems around the globe. The macroinvertebrate communities within these habitats underpin ecosystem functioning and therefore the provision of ecosystem services valued ... -
The effects of ocean acidification on microbial nutrient cycling and productivity in coastal marine sediments
(The University of Waikato, 2022)Ocean Acidification (OA), commonly referred to as the “other CO₂ problem,” illustrates the current rise in atmospheric carbon dioxide (CO₂) levels, precipitated in large by human-related activity (e.g., fossil fuel combustion ... -
Effect of exposure on the erodibility of intertidal mudflats
(The University of Waikato, 2021)Sediments on intertidal flats are exposed during low tides. Under the effect of exposure, the water content of sediments decreases because of the evaporation process, which alters the erosive behaviour of cohesive sediments, ... -
Detecting anthropogenic impacts on estuarine benthic communities
(The University of Waikato, 2021)Our estuaries, and the benefits that we derive from them, are threatened by the cumulative effects of interacting stressors. Separating the impacts of anthropogenic stressors from natural variability in the marine environment ... -
From ecology to the assessment of multiple ecosystem services; a case study of estuarine bivalves
(The University of Waikato, 2021)Estuarine and coastal environments provide a wide range of societal goods and services that need to be strategically managed to ensure sustainable use of resources. Ecosystem service (ES) assessments are transitioning from ... -
Investigating groundwater derived nutrient fluxes within Tauranga harbour, New Zealand
(The University of Waikato, 2021)Submarine groundwater discharge (SGD) is one of the key pathways that connects land and ocean, delivering freshwater, nutrients, carbon, metals, and other chemical constituents to coastal waters. In New Zealand, local Māori ... -
The influence of interacting stressors on soft sediment ecosystem function
(The University of Waikato, 2021)Soft sediment intertidal habitats provide valuable ecosystem services to millions of people worldwide yet are under intense anthropogenic pressure. In particular, the intensification of land derived sediment and nutrient ... -
Small-scale spatial patterns of Austrovenus stutchburyi in natural and translocated beds
(The University of Waikato, 2020)Ecosystems are patterned and patchy as a result of spatial and temporal variation in the abundance and distribution of essential resources, as well as due to geological and ecological processes. Large-scale patterns are ... -
Response and resilience of estuarine benthic ecosystems to anthropogenic pressures
(The University of Waikato, 2020)Human activities are altering coastal environments at local and global scales with largely unknown consequences. Catchment land-use changes increase the rates of delivery of fine sediments and nutrients to estuaries, ... -
Variation in benthic primary production during tidal emersion within different intertidal habitats
(The University of Waikato, 2019)Intertidal habitats provide a wealth of ecosystem services including fuelling oceanic food webs and processing nutrients however, understanding the response of these habitats to emersion has been largely overlooked. ... -
Dynamics of internal nutrient loading in a eutrophic, polymictic lake (Lake Rotorua, New Zealand)
(The University of Waikato, 2006)Lake Rotorua is a large (80 krn2), polymictic, eutrophic, shalJow (mean depth 10.8 m) lake in central North Island, New Zealand. Blooms of cyanobacteria and occasional anoxia of bottom waters are characteristic of the ... -
Contribution of seagrass (Zostera muelleri) to estuarine food webs revealed by carbon and nitrogen stable isotope analysis
(The University of Waikato, 2006)Seagrass is a conspicuous marine angiosperm that forms extensive beds in coastal and intertidal estuarine areas. In many regions worldwide seagrass is in decline and there is a pressing need to understand the function and ... -
Ecological effects of turbidity variations in and around dredging areas in the Port of Tauranga
(The University of Waikato, 2018)Turbidity is the scattering of light in water bodies and is an important measurement for assessing water quality in coastal systems. Suspended particles in the water column can greatly impact on light penetration and ... -
The effects of common carp on zooplankton communities using morphological and molecular techniques
(The University of Waikato, 2018)Understanding the factors causing a decline of water quality is important to ecologists, but particularly challenging given the complexity of natural systems. New Zealand’s freshwater ecosystems are under threat from ... -
Distribution of nematodes in pasture soil across seasons and in combination with plant species and fertiliser application
(The University of Waikato, 2018)The intensification of pastoral land use has increased with the use of fertilisers and the selection of highly productive pasture plant species to increase pasture production. When choosing a ryegrass cultivar infected ... -
The impact of macrophyte mats on biodiversity and ecosystem functioning of benthic communities
(The University of Waikato, 2018)Macroalgal blooms, such as Ulva spp., are a common disturbance to estuarine benthic fauna worldwide. As large quantities of macroalgae break free from growing substrates, drifting mats are formed that eventually deposit ... -
Do benthic macrofauna functional groups or their key constituent species better predict variation in ecosystem functioning?
(The University of Waikato, 2018)Estuarine ecosystems are important zones for primary productivity and nutrient processing, have rich communities of plants and animals and support important fisheries and are fundamental to food webs. Intertidal habitats ... -
Transport and retention of benthic marine invertebrates in the Southern Tauranga Basin
(The University of Waikato, 2018)Dispersal is the process in which individuals are transferred between populations, and is essential for population sustainability and longevity. In estuarine soft sediment communities, dispersal often occurs as the interaction ...
