Main Research Interest
- social parasitism in ants
- myrmecophily
- interactions between ants and fungi
- ant biodiversity
- division of labour in social insects
- development of personality in ants
Current projects
- Susceptibility of ant colonies for social parasitism and the impact of social parasites on host colony fitness (NCN: UMO-2012/04/S/NZ8/00218). In this project I study the effect of social parasites on ant colony fitness and arm race between Myrmica host ants and their social parasites Maculinea butterflies. I also try to look which ant colony traits can make them more prone for social parasitism.
- Influence of goldenrod invasion on Myrmica ant colony life history traits.
- Relationship between Myrmica ants and their parasitic fungus Rickia wasmannii.
- Studies on inquiline social parasite- Myrmica karavajevi.
