BLI Community Ecology Research Group

Leader of the research group: 
Profile of the group: 

1. Diversity and composition of ecological communities
The main objective of the group is to study ecological communities. We focus mostly on freshwater macroinvertebrates. We apply wide variety of approaches (observational and experimental studies, meta-analyses and modelling) and focus on the causes and consequences of patterns in diversity and composition.

2. Human impacts on freshwater biodiversity
We examine the effects of human impacts on freshwater biodiversity. We focus on how the different facets (taxonomic, phylogenetic and functional) and components (alpha and beta) of diversity, as well as the taxonomic- and trait-based community respond to anthropogenic disturbances such as urbanization, pollution or habitat degradation.

3. Numerical ecology
We deal also with the methodology of community ecology. We are interested in approaches quantifying community-level phenomena such as beta diversity or nestedness, as well as in methodology enumerating functional diversity.
