Experimental Plant Ecology

Plant Ecology

Two of the most pressing challenges facing ecologists are forecasting the spread of non-native species and predicting the response of native species to global climate change. To tackle these challenges, research in our group aims to decipher the ecological and evolutionary forces that shape plant species’ distributions and community structure. In particular, we combine field experiments with ecological modelling to study how altered biotic interactions influence species’ range dynamics under changing climate. We also study global patterns and processes in plant invasions along elevation gradients to better understand the dynamics and impacts of biological invasions.
