1. Community-level effects of biological invasions
In a research project starting in 2021 I will study the consequences of multispecies invasions on vegetation diversity.
2. Plant community assembly
We study co-existence patterns and mechanisms using taxonomical and trait information, assembly models, and analytical methods of community ecology. Most of our sample sites are located on grassland of the Kiskunság region.
3. Testing and developing statistical methods used in ecology
During the statistical analysis of ecological data, I enjoy giving creative solutions to methodological challanges, and some become useful for the broader scientific community.
4. Vegetation classification
I lead and contribute to several projects aiming at the description of the diversity of broader vegetation types (e.g. mesic meadows, oak forests on loess). Such projects have typically broad geographical coverage inlcuding several countries, and they utilize either taxonomical or trait information of species as variables.
