Popis

I specialize on insect-plant relationships, evolution of plant defensive traits, and chemical ecology. In general, I am interested in insect-plant coevolution and factors driving diversification of insects and plants and evolution of plant defences.

I am involved in projects examining latitudinal gradients of insect biodiversity. Mainly, we are trying to answer the question why are there more species of insect herbivores in tropical than temperate forests. To investigate this we sample canopy assemblages of key herbivore guilds using several techniques such as sampling from canopy cranes or cherry-pickers.

Further, I am interested in evolutionary trends in Ficus and Salix defences and their impact on herbivore community assembly. Both Ficus and Salix are key plant genera supporting large diversity of insects in tropical forests and temperate wetlands. Understanding evolution of their defences is thus crucial for understanding not only the evolution of host-plant defences in general but also for understanding the factors driving diversity and specialization of insect herbivores.
