I am a molecular ecologist that uses genomics and statistical models to understand natural populations, particularly marine mammals. The role of behaviour in shaping how connected different groups or populations has been a particular theme in my research; this has including migratory fidelity and migratory culture in southern right whales.
My Rutherford Discovery Fellowship is on "Family Matters: Developing close kin mark recapture methods to estimate key demographic parameters in natural populations". This is work with Assoc. Prof. Rachel Fewster, UOA, Assoc. Prof Simon Jarman, Dr Mark Bravington, Assoc. Prof. Rochelle Constantine and Prof. C. Scott Baker.
Conventionally, the only way to estimate key population demographic parameters critical for management and conservation (abundance, survival, growth rates) was from long-term studies that follow individuals over their lifetime. In this project, we will use close kin mark recapture (CKMR), which extends the field of capture-recapture models that are predicated on the recapture of individuals, to include the recapture of close kin to estimate demographic parameters. The CKMR method has striking advantages over conventional analyses because the effective sample size is higher than the actual number of individuals sampled: individuals will be recaptured in the genome of their kin even if not physically recaptured. More importantly, when combined with age data, CKMR requires only a short-term, cross-sectional sample of a population, not decades-long datasets. In addition to providing valuable information on an endangered species, the southern right whale, this work will generate new methodologies that can be applied more broadly in the field of ecology.
