Hang Thi Thuy Nguyen

PhD (Otago). The ecophysiology of coralline algae in Southern New Zealand. Hang’s research looks at the ecology of coralline algae within the East Otago Taiāpure. Hang’s work includes research on the nutrient physiology of coralline algae, and looks at using different irradiance levels to evaluate the ability of coralline algae to carry out photosynthesis. This research also looks at the effect that different temperatures have on photosynthesis in coralline algae.

 

 

 

Eugene Leahy

MSc (Otago). Expansion and Harvestability of Undaria pinnatifida throughout North Otago CPAs.  Eugene’s research looks at the expansion of the invasive seaweed species Undaria in the East Otago Taiāpure. This work looks at the expansion of both geographic range, and depth, as well as the effects of expansion upon native species in Otago. Eugene’s research also looks at the feasibility of harvesting Undaria in customary protection areas. This research has the aim of identifying if range expansion has occurred, evaluating indications of any negative effects on the native seaweed community, and assessing opportunities for Undaria harvest in the East Otago Taiāpure.

 

Simone Jarrett

MSc (Otago). Causes of coralline algae bleaching within the East Otago Taiāpure. Simone’s research is investigating the causes of coralline algae bleaching. It investigates whether high light dosage and/or temperature induces bleaching of some of the species found in the East Otago Taiāpure, with a focus on the species Arthrocardia corymbosa. Simone’s research also surveys the extent of bleaching seen in Butterfly Bay in the East Otago East Otago Taiāpure.

 

 

Anna Kluibenschedl

PhD (Otago). Future Ocean and New Zealand Coralline Algae: Biological and Ecological Responses Under Elevated pCO2. Anna’s work is focused on crustose coralline algae (CCA) and the impacts of the expected changes in our oceans. Her work is centered around the CCA occurring within the East Otago Taiāpure. Combining information from ongoing  pH-monitoring efforts in the Taiāpure and laboratory experiments, she tries to understand how CCA are going to be affected by increased carbon dioxide levels in the ocean. Studying the effects of increased carbon dioxide on these algae might help us to better understand implications for other organisms.
