Summary:
It is often assumed that plant functional traits, measurable characteristics of species linked to organisms’ functions, should
affect species performance through various components of species fitness. We aim to verify empirically this assumption in
species rich grasslands and, specifically, to explore more in depth the relationships between above- and below-ground species
traits, their environmentally induced variability and different components of species demography and performance. These
components will be assessed from long term removal and grassland management experiments (sampled for 20 years
continuously) which yield both above- and below-ground responses to competition. Species-specific data on root distribution
will be determined using molecular techniques based on next generation-sequencing and real-time PCR. The research will
provide hard data on core links between both above- and belowground plant traits and species performance in the field and it
will illustrate how to account for the environmental-contingency in the link between traits and plant performances.
