Studies on the effects of climate change to date have focused on long-term change in variables such as temperature and ocean acidification. An emerging gap is the immediate and potentially devastating effects of marine heatwaves that cause extreme temperature changes in surface waters. Sessile species like pāua are especially vulnerable to heatwave events since their growth and development are influenced by water temperature. Their primary food source, macroalgae, is also negatively impacted by warming waters. During recent marine heatwaves, some populations of pāua on the Chatham Islands exhibited signs of growth stunting and starvation. This project will provide a toolkit of bioindicators that to help understand the impacts of marine heatwaves on pāua condition. Understanding the mechanisms driving recovery or mortality in animals impacted by heatwaves can guide fishery management practices.
Overall Objective:
This project aims to analyse the potential causes of growth stunting in pāua sampled during a marine heatwave event in New Zealand.
Specific Objectives:
1. Complete a suite of analyses on pāua sampled before during and after a heatwave event as a case study to identify the likely causes of starvation observed in pāua.
2. Broader outcomes.
