The project deals with biodiversity of large central European cities. It will use standardized sampling protocols in selected man-made habitats and selected cities, representing areas of central Europe with different macroclimatic and socioeconomic characteristics. The focus will be on two model taxonomic groups: vascular plants and land snails. The main questions are: (1) How does spread of alien species depend on the macroclimate of different parts of Central Europe and different types of urban habitats? (2) Does urban environment positively or negatively affect diversity of native species and overall species richness of the selected taxonomic groups? (3) Does urbanization cause biotic homogenization, and if so, is homogenization manifested both at the level of species and the level of species traits? Which habitats and species groups are most homogenized? (4) Are the patterns in urban diversity consistent between different taxonomic groups?
