- Temporal stability and plant niche complementarity

Temporal stability and plant niche complementarity


Jena Experiment

The quest to find the underlying mechanisms of observed productivity-biodiversity relationships has often focused 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 main Jena Experiment. However, with the new trait-based experiment, we can now address such aspects at species and community levels.

We will acquire high temporal and spatial resolution datasets on optical properties and use a unique combination of state-of-the-art techniques, including terrestrial laser scanning (LiDAR) techniques at sub-daily to bi-weekly time steps, fine-scale canopy inventories, spectral foliar analyses as well as already existing data sets from the main plots on traits and phenology.

Based on these high-resolution measurements, 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.
