Effects of environmental change on anemonefish demography

Supervisory team in UK: Dr Isabel Smallegange, Dr Theresa Rueger

Partners: Mahonia Na Dari Research and Conservation Centre (Kimbe Bay, Papua New Guinea)

Keywords: demographic modelling, coral reefs, anemonefishes, SCUBA, field work

Aim:

To perform a demographic analysis of the life history of the clown anemonefish, Amphiprion percula to understand it sensitivity to environmental change.

Objectives and hypothesis:

In this research you will use existing data (and optionally collect data yourself) on the survival, growth and reproduction of a population of Amphiprion percula in Kimbe Bay, Papua New Guinea, to create the first demographic model of this species. You will (1) create a dataset of mortality, growth and reproduction of the population using existing records, (2, optional) collect data yourself by travelling to Kimbe Bay and measure known individuals, and (3) use your life history dataset to create and analyse a demographic model using MatLab. This will allow you to explore the population consequences of variation in demographic rates of this iconic coral reef fish species and assess its sensitivity to environmental change. The project does not require prior modelling experience, though an enthusiasm to learn such techniques is preferred. Field components are optional.

Learning Outcomes:

  • Conducting a research project that follows the empirical cycle of coming up with a hypothesis set in a general background, and then testing it using the demographic analysis and assessing its implications.
  • Data management and analyses.
  • Life cycle analysis and demographic modelling using MatLab.
  • Optional: If the candidate is a SCUBA certified diver there will be an opportunity to do field work in Kimbe Bay, Papua New Guinea. There you can learn field techniques such as measuring fish and anemones. Engagement with local NGO Mahonia Na Dari and their education program will be encouraged.
  • Co-writing of a scientific paper for submission to a journal in the discipline.

Target Journal: Peer J, Ecology & Evolution, or similar journals.
