How environmental change is affecting ecosystems
Current work within Prof. Andrew Lowe's group involves ecological analysis of vegetation communities within a regional monitoring transect we have established between the Mount Lofty Ranges and northern Flinders Ranges, South Australia (the TREND transect). The main research focus is on patterns of ecosystem composition and functional responses to changes in climate through space and time. Through this work we hope to better understand how Mediterranean ecosystems in southern Australia respond to environmental change and apply new information on climate change impacts to practical interventions.
Taxonomy of Australian Lamiaceae
On-going research involves taxonomic revision of the genera Hemigenia and Microcorys (classification and species-level) and investigation of the evolution of stamen morphology and pollination systems (with Prof. Dr. Regine Claßen-Bockhoff's group).
