Pecten novaezealandiae at its southern limit: habitat dynamics and ecology within Paterson Inlet, Stewart Island
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 ...
Biology of the sea pen Pteroeides sp. in Fiordland, New Zealand
The sea pen Pteroeides sp. shows variability in size frequency distributions and density between areas of a population, suggestive of spatially unpredictable and patchy recruitment. The spatial distribution of colonies ...
The effects of ocean acidification on juvenile Haliotis iris
The world's oceans are increasing in levels of anthropogenic CO2 resulting in reductions in seawater pH and the availability of carbonate ions which are essential to calcifying marine species. Ocean acidification is ...
Behavioural ecology and population structure of Hector's dolphin (Cephalorhynchus hectori)
Aspects of social structure, behavioural ecology, and population biology of Hector's dolphin (Cephalorhynchus hectori) were studied. Especially information on ranging behaviour and group composition of this species were ...
The ecology of the invasive kelp Undaria pinnatifida: functioning at an ecosystem level.
The Asian kelp, Undaria pinnatifida (Harvey) Suringar 1873, is considered to be one of the world’s most invasive species and is well established around the New Zealand coastline. However, ecological implications of U. ...
Effects of ocean acidification on fertilisation and early development in polar and temperate marine invertebrates
Ocean acidification is the alteration of seawater carbonate chemistry due to the sequestration of atmospheric carbon dioxide (CO₂) into the ocean. An increase in dissolved CO₂ (pCO₂ (aq)) in surface waters has caused a ...
New Zealand sea lion abundance, demographics and movements in southern New Zealand
This study represents the first comprehensive survey of the New Zealand sea lion, Phocarctos hookeri populations at Campbell Island, the first surveys in nearly 30 years at The Snares and the continuation of a monitoring ...
Does nutrient enrichment contribute to coral bleaching? A Fijian case study
This study investigated the effects of nutrient enrichment and thermal stress on the cellular and photosynthetic response of a dominant, reef-building coral in Fiji. Porites cylindrica corals were collected from Votua, ...
Distribution and ranging of Hector's dolphins : implications for protected area design
The efficacy of a Marine Protected Area (MPA) is contingent on it having a design appropriate for the species it is intended to protect. Hector's dolphin (Cephalorhynchus hectori), a coastal delphinid endemic to New Zealand, ...
Ecology of Hector's dolphin (Cephalorhynchus hectori): Quantifying diet and investigating habitat selection at Banks Peninsula
Hector’s dolphins (Cephalorhynchus hectori) are endangered and endemic to New Zealand. Although their distribution and abundance have been thoroughly described, little is known about Hector’s dolphin ecology. Being small ...
