From rivers to ocean basins – quantifying sex-specific connectivity in sharks
My PhD project aims to quantify fine-scale, sex-specific connectivity in sharks. To accomplish this, neonates from spatially well-defined nursery areas will be examined and genotyped for sex-linked regions. Connectivity in sharks will also be analysed on a global scale in order to provide critical information on management units for species conservation and fin trade management. Candidate species include the Endangered river shark species (Glyphis glyphis and G. garricki) and the iconic bull shark (Carcharhinus leucas). The first two species will be analysed as part of NESP Marine Biodiversity Hub: Northern Australian hotspots for the recovery of threatened euryhaline species. In the end, understanding male-specific gene flow and female philopatry will provide policymakers with crucial information on population dynamics and boundaries.

My previous research has always focussed on applying molecular techniques to answer ecological questions. My master thesis investigated a recent biological invasion of an Australian mussel (Xenostrobus securis) and the best actions for eradication. During 6 months of volunteering at James Cook University, I looked at the diet composition from three sympatric coral trout species. In addition, we also examined which genetic marker exhibit the best qualities for metabarcoding in tropical reef predators. Furthermore, I helped on some small projects, including ‘Effects of ketogenic diet on gut microbiome and schizophrenia-like behaviour in mice’ and ‘Coral microbiomes: their habitat distribution and response to environmental changes’. Finally, during a short-term employment at CSIRO I analysed genomic data to identify population differentiation on a fine scale in Australian and New Zealand school sharks (Galeorhinus galeus).
