The quest to find the underlying mechanisms of observed productivity-biodiversity relationships has often focussed on nutrient, light and water use complementarity. In contrast, architectural and phenological diversities giving rise to spatial and temporal niche complementarities have hardly been addressed in the Jena (main) Experiment. However, with the new trait-based experiment, we can now address such aspects at species and community levels. In particular, we will acquire high temporal and spatial resolution datasets on optical properties (WP1) that will allow us to address the following questions: How does diversity in plant stature and architecture translate into efficient exploitation of above-ground space? (WP2); how do phenological niches change in response to diversity, allowing communities to exploit resources over an extended period of time? Can phenology models - predicting community stand development and productivity solely with climate inputs - be improved by including information on plant diversity? (WP3); how does diversity, i.e., species richness, architectural and phenological diversities, affect magnitude and temporal development of plant and ecosystem transpiration and water-use efficiency? (WP4). We will use a unique combination of state-of-the-art techniques, including digital imaging techniques at sub-daily to bi-weekly time steps (time-lapse, close-range, thermal), fine-scale canopy inventories, phenological trait assessments at plant species and community level, spectral, chemical and isotopic foliar analyses as well as already existing data sets from the main plots (on traits, phenology and surface temperatures). Based on these high-resolution measurements within the trait-based experiment and validation measurements on the main plots, we will acquire proxy data of community structure and functioning to address our overarching hypothesis that spatial and temporal niche complementarities contribute to the observed biodiversity effects on ecosystem functioning.
