The biogeography and trophic roles of coastal marine sponges (Porifera) from the west coast of the North Island, New Zealand: Influences of catchments.
(The University of Waikato, 2021)Anthropogenic activities are degrading coastal marine ecosystems globally. While the ecological and biodiversity implications of some of these impacts are well understood, for others there is a need for a greater understanding ... -
Microplastics in the marine environment: Sediment contaminant and bioaccumulation rates in bivalves within the Bay of Plenty
(The University of Waikato, 2021)Microplastic pollution is recognised as a significant anthropogenic issue in coastal ecosystems around the world. The accumulation of microplastics in coastal environments causes both direct and indirect effects on these ... -
Habitat use and trophic ecology of bronze whaler sharks (Carcharhinus brachyurus) in New Zealand
(The University of Waikato, 2021)Sharks are among some of the most diverse and abundant top-level predators within marine ecosystems. Their predatory role in controlling the population size, distribution and behaviour of species within the lower levels ... -
Comparing competitive interactions and settlement success among native and non-indigenous species in marine hard bottom communities of colonial ascidians, from the Bay of Plenty, New Zealand
(The University of Waikato, 2020)The requirement for space in marine hard bottom assemblages is paramount for life. Due to the crowded nature and demand for space in these sessile assemblages, bare space that is freed is quickly occupied. The intense push ... -
New Zealand seagrass (Zostera muelleri) response to acute sedimentation: Linking non-structural carbohydrate reserves to resilience
(The University of Waikato, 2020)Seagrass meadows form healthy near-coastal marine environments that provide a wide range of ecosystem services in New Zealand and Australia. However, seagrass habitats are declining regionally and globally. It is therefore ... -
The ecology of ray species in an urbanised estuary: seasonality, habitat use and pollutant exposure in Tauranga Harbour.
(The University of Waikato, 2020)Information about the movement, seasonality, and use of habitats by marine animals is vital for the mitigation of potential anthropogenic impacts. Ray species may be particularly at risk as they regularly inhabit coastal ... -
The quantification of external colour changes during sexual transition in the protogynous spotty wrasse Notolabrus celidotus
(The University of Waikato, 2019)Hermaphroditism in fish has been well documented. Protogynous hermaphrodites (female to male sex change) are normally found in a polygamous social hierarchy. The male is the dominant within the group, followed by the largest ... -
Marine demosponge responses to a changing ocean; effects of sedimentation and temperature increases on Tethya burtoni metabolism
(University of Waikato, 2017)As atmospheric CO₂ levels currently increase at an unprecedented rate, the effects of climate change are increasingly recognized as a significant threat. Changes to climate are predicted to influence natural systems, ... -
Managing the Unwanted Organism Sabella spallanzanii (Gmelin, 1791): investigating how desiccation, fragmentation and acetic acid can be used to manage this pest on aquaculture facilities.
(University of Waikato, 2017)Human activities have enabled non-indigenous marine species (NIMS) to cross geographic barriers outside their natural dispersal range. As a novel habitat, marine aquaculture facilities often grow NIMS, or are fouled by ... -
The Fate and Effects of Contaminants in Estuarine Environments
(University of Waikato, 2017)Estuaries are sensitive environments regarding their response to anthropogenic events. The accumulation of toxic trace elements, such as Cd and Pb, has detrimental consequences on benthic community composition and function ... -
Characterisation, potential toxicity and fate of storm water run-off from log storage areas of the Port of Tauranga.
(University of Waikato, 2015)Stormwater run-off from industrial sources can impact the receiving environment by the discharge of toxic substances, nutrients, sediments or fresh water (in marine environments). The Port of Tauranga is New Zealand’s ...
