Insights into the nitrogen ecophysiology of Macrocystis pyrifera
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 ...
Blue cod (Parapercis colias) population structure & connectivity in the New Zealand fjords
Tagging and stable isotopic studies suggest that blue cod (Parapercis colias) in Fiordland form discrete sub-populations at the scale of tens of kilometres with a high degree of residency, particularly in the inner fjord ...
A post-glacial relative sea level curve for Fiordland, New Zealand
During the sea level lowstand of the Last Glacial Maximum, the entrance sills of the New Zealand fiords were above sea level. With de-glacial onset, stranded lakes developed behind the sills in the fiord basins, and as sea ...
Southern right whales (Eubalaena australis): Acoustic behaviour and ambient noise
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 ...
Carbonate production by two New Zealand serpulids : Skeletal allometry, mineralogy, growth and calcification of Galeolaria hystrix and Spirobranchus cariniferus (Polychaeta: Serpulidae), southern New Zealand
This study investigates the skeletal allometry, mineralogy, growth and calcification of two New Zealand serpulids, Galeolaria hystrix and Spirobranchus cariniferus. Tube allometry (length, diameter, wall thickness, carbonate ...
The developmental responses of two closely related species of sand dollars, the tropical Arachnoides placenta, and the temperate, Fellaster zelandiae, to varied seawater temperature and pH
Two of the major climate change factors expected to effect marine life, in the near future are changes in seawater temperature and pH. The Intergovernmental Panel on Climate Change, IPCC, assessment report from 2013 predicts ...
Optimising design of large tidal energy arrays in channels: layout and turbine tuning for maximum power capture using large eddy simulations with adaptive mesh
Tidal energy has the potential to generate sustainable electricity from tidal flows using arrays of turbines. This thesis is the first exploration of the layout of large arrays in channels to explicitly model turbine-scale ...
The effects of UVR and Suncreen Compounds on Sea Urchin Larval Respiration along a Latitudinal Gradient
Sea urchin larvae are particularly vulnerable to enhanced ultraviolet radiation (UVR) exposure as they are small, highly transparent, undergo rapid cell division and occupy the upper regions of the water column. Anthropogenically ...
Factors influencing the recovery of Pecten novaezelandiae within Te Whaka ā Te Wera Mātaitai, Rakiura
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 ...
Phytoplankton responses to seabird guano fertilisation in the Southern Ocean.
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 ...
