Dr Clarke uses genetic approaches to inform management of biodiversity in the face of threats such as invasive species, habitat fragmentation and climate change.
As ARC post-doctoral fellow at the Australian Centre for Ancient DNA (ACAD, University of Adelaide), Dr Clarke led a group using environmental DNA (eDNA) approaches and high-throughput sequencing to perform biodiversity surveys in aquatic and terrestrial ecosystems.
His research experience includes; population genetics studies on several plant species; exploring the environmental determinants of vegetation patterns at spring-fed wetlands in central Australia; investigating UV-screening strategies of Antarctic mosses; and analysing radioactive and stable carbon isotope profiles to explore the influence of environmental change on Antarctic plants.
