Explaining mechanisms of coexistence in species-rich and structurally diverse forests is still a
great challenge in ecology. Niche-based processes, reflecting differences in functional traits of
neighbouring trees, provide a viable explanation of forest dynamics. This project aims to
investigate how functional traits contribute to community dynamics in temperate and tropical
forests by mediating tree interactions with neighbours, enemies, and mutualists across different
environmental contexts and spatio-temporal scales. Using several observational and
experimental approaches associated with large tropical and temperate forest plots, we plan to
explore the effects of 1) similarity of functional traits on the coexistence with neighbouring trees,
2) adult trees, natural enemies and mycorrhizal fungi on seedling performance and traits, and 3)
species- and individual-level functional traits during the regeneration phase. This will
substantially advance our understanding of the effects of tree’s functional traits for the
coexistence of tropical and temperate tree species

Although regional meadow seed mixtures have been used in our country for a long time, these are only local activities. The project investigates the methods that are most suitable for the near natural restoration of species-rich meadows (brushed plant biomass containing seeds, green hay transfer, threshing). The efficiency of different brush collectors is being tested, from the smallest hand-held collector to manually pushed collectors up to the tractor-guided collector. The project has several objectives: 1) to find as many diverse meadows as possible across the country that can serve as a source of seeds, map them, and enter them into a database; 2) to test different seed collection technologies in different conditions and evaluate their benefits and limitations; 3) to disseminate all the collected knowledge and experience to the general public

This is a project directed by the PI group from Institute of Botany, Třeboň, the plant functional ecology group of our department is co-PI. Our group is mainly responsible for the Carex workpackage, investigating the differentiation of functional traits within individual Carex species, and between the species. We use the range of methods, from a glasshouse experiments investigating effects of biotic interactions and abiotic conditions on Carex species trait, and landscape scale measurement of traits in relationship with host plant communities of several populations of each of ca 20 Carex species.

Project is based on the idea that the main driver of competitive exclusion in plant communities is mainly competition asymmetry, and not so much competition intensity. The rate of competitive exclusion increases with competition asymmetry. It is expected that the aboveground competition is more asymmetric than the belowground competition, but the experimental proof is missing. In the project, we use newly established experiments, as well as the long-term data from our permanent plots (mainly Ohrazení). Common project with the working group of Tomáš Herben (Botanical institute CAS, Průhonice).
