How mutualism, cooperation between different species, evolves and remains stable over evolutionary time, are major outstanding questions in evolutionary biology. To address these questions, I have adopted subterranean ant-trophobiont-microbe interaction networks as study systems. My research is organized in the following four research lines, of which three are empirically and one is theoretically focused.

Ant-trophobiont ecological interaction networks

Using DNA barcoding and morphology, I map specificity in subterranean networks of ants, trophobionts (aphids and mealybugs), their gut bacteria and the trophobionts’ host trees.

Microbiomes in ant-trophobiont mutualisms

Both ants and their trophobionts have specialized bacteria in their gut that facilitate nutrient uptake and excretion. I study bacterial presence and diversity and what role the microbiome plays in ant-trophobiont mutualism.

Partner choice in ant-trophobiont mutualisms

This theme ties the previous two together. The prime commodity of ant-trophobiont mutualisms is ‘honeydew’, the sugary excrement of aphids. I study whether the ants’ preference for certain aphids can be influenced by the ants’ and trophobionts’ gut bacteria.

Universal patterns in mutualistic networks

Using computer simulations, I study whether some network architectures may favor mutualism evolutionary stability over others and whether networks can be modulated by organisms that are not directly involved in the mutualism.
