(Thesis, Master of Science, 2017)Estuaries represent a transitional environment influenced by both terrestrial and marine processes. There are several types of estuary defined by their connectivity with the marine environment that are found along coastlines ... -
(Thesis, Master of Science, 2017)Photography is one of the most widely used tools in conservation biology. In the analysis of social species, analyses of photographic identification data are used to infer the degree of association among uniquely marked ...

(Thesis, Doctor of Philosophy, 2017)Paphies ventricosa is a large surf clam endemic to New Zealand with a patchy distribution and whose populations have substantially declined during the past century owing to overfishing and habitat degradation. Poor recruitment ... -
(Thesis, Doctor of Philosophy, 2017)The loss of canopy-forming macroalgae is one aspect of coastal ecosystem degradation that is being driven by anthropogenic stressors. The drivers of canopy loss are, in many cases, well understood, but the effect of light ... -
(Thesis, Master of Science, 2017)Hard parts of squid are used in a variety of post mortem analyses, such as diet studies, which shed light on various aspects of the squid’s life. In this thesis, hard parts were reviewed. Beaks and statoliths were found ... -
(Thesis, Doctor of Philosophy, 2017)Deep-sea meiofaunal communities vary at a range of spatial scales. However, identifying which scale(s) account for most of the variability in deep-sea communities remains difficult, as few studies have been designed in ... -
(Thesis, Master of Science, 2016)The broadnose sevengill shark, Notorynchus cepedianus, is an important marine apex predator found in temperate coastal regions worldwide. Despite being identified as an abundant, high trophic level species, there is a ... -
(Thesis, Master of Science, 2016)The present study quantifies the effects of various water masses, including the oceanic, neritic, and coastal waters, on the abundance and distribution of surface macro-zooplankton off the Otago Coast through a series of ... -
(Thesis, Master of Science, 2016)Anthropogenic carbon dioxide (CO2) emissions are causing long-term changes in ocean carbonate chemistry. This process, ocean acidification (OA), produces reduced seawater pH and overall shifts in carbonate chemistry. ... -
(Thesis, Master of Science, 2016)Investigating how environmental variation influences population, food web, and community dynamics is important for predicting the influence of climate change on ice covered ecosystems. The sea ice gradient that runs from ... -
(Thesis, Master of Science, 2016)Ocean acidification refers to the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide from the atmosphere. This ocean acidification is considered to be a threat to marine organisms and ... -
(Thesis, Master of Science, 2016)The New Zealand scallop (Pecten novaezelandiae) is an important customary and recreational species in Whaka ā Te Wera, Rakiura (Paterson Inlet, Stewart Island). Customary management tools such as Mātaitai reserves allow ... -
(Thesis, Doctor of Philosophy, 2016)Great congregations of seabirds in coastal areas of the Southern Ocean result in delivery of nutrient-rich guano to coastal waters potentially enhancing productivity and supporting biodiversity in the region. The magnitude ...
-
(Thesis, Master of Science, 2016)Under future ocean warming, thermal tolerance of developmental stages may be a key driver of changes in the geographical distributions and abundance of marine invertebrates. Additional stressors such as ocean acidification ...

(Thesis, Doctor of Philosophy, 2015)Low nitrogen availability is one of the major environmental factors limiting macroalgal growth in temperate marine ecosystems. Macroalgae have overcome the fluctuating nature of nitrogen supply via adjustments to their ... -
(Thesis, Master of Science, 2015)A seismic survey was collected between March and October 2013 using the RV Polaris II on the inner‐mid Otago continental shelf. The survey included ~200 km of high resolution single channel boomer seismic, CHIRP and side ... -
(Thesis, Master of Science, 2015)Commercial fishing often reduces densities and changes the structure of target populations. Within these target populations, the transmission dynamics of parasites are usually strongly dependent on host densities. Because ... -
(Thesis, Master of Science, 2015)The in situ nitrogen (ammonium and nitrate) uptake kinetics of Macrocystis pyrifera and the potential for M. pyrifera to be used in an integrated multi-trophic aquaculture (IMTA) approach with salmon (Oncorhynchus tshawytscha) ... -
(Thesis, Doctor of Philosophy, 2015)Anthropogenic noise in the ocean is steadily increasing as more industrial and recreational activities occur in coastal and offshore areas. Responses of marine mammals to noise vary widely, ranging from temporary behavioural ... -
(Thesis, Master of Science, 2015)The New Zealand scallop (Pecten novaezealandiae) is a species of high commercial, recreational and customary value. Productivity within scallop fisheries is highly variable due to sporadic recruitment, high mortality and ...
