Plants, microbes and insects
Plant-based species interactions

This lab revolves around plant-based species interactions. Our key aim is to use experimental, theoretical and molecular techniques to study interkingdom interactions between plants, microbes and insects. For this, we will initially focus on two familiar study systems: the below- and aboveground food web surrounding the plant Plantago lanceolata, and the pathogen and insect metacommunity on the pedunculate oak (Quercus robur). In the coming years we hope to explore new study systems, like the smut fungus on the evening primrose (Primula farinosa) and the microbial community associated with Sweden’s wild plants. Overall, we are broadly interested how ecological and evolutionary interactions between plants, insects and microbes play out in a spatial setting.
