Rachel Louise Gunn
Rachel is interested in intraspecific variation in the personality of butterflyfish (Chaetodon spp.) and how these differences will allow species to potentially buffer the effects of coral bleaching and persist under future environmental conditions. Rachel will be conducting fieldwork in Indonesia, funded my Operation Wallacea, to identify personality differences between butterflyfish individuals both between and among reefs.
Through a combination of this field work, pre existing data analyses and modelling techniques, her PhD considers four broad questions:
- How variable is personality amongst individuals, within and across reefs?
- How does this variation relate to habitat complexity?
- Do fish populations on reefs that have undergone recent mass coral mortality have a higher frequency of bold, explorative individuals?
- How do these differences in personality frequency scale up to impact the potential for species to track changing climate?
