I have always had a fascination for the incredible diversity of life forms that inhabit the earth. Each habitat or ecosystem has it own suite of species that seem particularly well adapted to their specific environmental conditions. What are the adaptations that make species thrive in their own particular habitat and how could these adaptations possibly hamper them in establishing in neighboring habitats (i.e. generalization, specialization, trade-offs, phenotypic plasticity)? What mechanisms enable the coexistence of many species? SW Australia, as one of the world’s 34 biodiversity hotspots, seems particularly well suited to address some of these key evolutionary questions. Therefore my overall research objective is to use my skills in plant ecophysiology to greatly enhance our understanding of plant species distribution patterns. This is especially relevant to the many threatened plant species in SW Australia. Their continued persistence in a much warmer and possibly drier climate is largely dependent on our understanding of these species’ habitat requirements (i.e. biotic and abiotic), threats and evolutionary potential. Therefore my research aims at providing basic knowledge on the evolutionary drivers of plant species rarity and commonness, but is also essential for the conservation of threatened species and communities.
