Symposium 6: Linking data to wildlife management through complex ecological models

Media: Digital image drawn on the iPad app, “Paper”


I am a Postdoctoral Research Fellow at the Centre of Excellence for Environmental Decisions at the University of Queensland in Brisbane. I drew these images during my PhD, which was focussed on analysing wildlife population declines.  My research is focused on two main topics: developing decision frameworks for prioritising threatened species conservation and understanding how differences in wildlife population time-series can inform management across populations. These abstract images are based on different wildlife population dynamics, which were simulated using the logistic equation.  They represent, respectively, the convex, linear and concave curve-shapes I identified in populations on their descent to extinction. Together, these images attempt to raise awareness about the global loss of biodiversity due to human-mediated habitat degradation, overhunting, and the introduction of non-native species to natural environments. I have always been interested in art and I am especially inspired by the beautiful, abstract patterns that arise in nature.
